Projects: “If We Had No Crawdad, We Ate Sand”

Almost every guide to the proper care and feeding of carnivorous plants emphasizes, after using rainwater or distilled water, the proper soil mix. All of them tell enthusiasts that using standard potting mix will kill the plants in a matter of days, and many give recipes for a suitable general carnivore potting mix with a suitable acidity for healthy growth. As a general rule, one part sphagnum moss and one part sand is perfect, and some varieties work best with two parts sphagnum moss, one part sand, and one part shredded orchid bark. But what about the quality of all of these?

With the sphagnum moss and the bark, some authorities warn about making sure that these are of high quality. For instance, many retailers sell sphagnum moss with added fertilizer, which will kill your plants, or the sphagnum is cut with green moss, which has the same effect. Coir, which is shredded coconut hull, can be just as dangerous if not properly prepared, as many suppliers use coir that’s been soaked in or exposed to seawater, and the salt will, again, kill most carnivores. The quality of sphagnum moss can be checked by making sure that a bag or bundle specifically reads “PURE SPHAGNUM MOSS” and smelling the bag or bundle, as contaminated sphagnum moss tends to smell like old manure. Even salt-soaked coir can be used if it’s soaked and rinsed with rainwater, and then drained and dried. But how often does anyone check the quality of the sand they’re using?

Check most references on carnivores, and see what they have to say about sand. You’ll get recommendations not to use sea sand, because it might be contaminated with salt. You might get recommendations to use sharp or builder’s sand, which means all-silica sand. But are you sure that you’re using the right sand?

My question comes from personal experience from two years ago. The first thing I do every spring before my plants come out of dormancy is repot them, and the spring of 2006 was no different. My mistake was not to check the composition of that sand, trusting the label “Builder’s sand” on the bag, and that sand led to most of my plants dying before the end of the summer. True, the 2005-2006 drought and the summer’s heat wave contributed to the carnage, but the main cause was the quality of the sand.

The mistake I made was assuming that the sand being offered was pure silica. Pure silica sand is reasonably water-insoluble, which is why it settles into water instead of dissolving. Some will, but usually not enough to make a difference in horticulture. The problem is that most sand offered for sale can be and is contaminated with anything else that happened to be in the in the mix. If the sand was mined in an area that used to be a marine deposit, for instance, it can be full of shells. If the sand came from a river deposit, it may be full of limestone chunks or other carbonate rocks. All of these contaminants are very alkaline, which is enough of a problem to most carnivores save some purple pitchers (Sarracenia purpurea) or the Portuguese dewy pine (Drosophyllum lusitanicum). Anyone who’s mixed acids and alkalis in high school chemistry class has a pretty good idea of what happens when alkaline components of sands encounter highly acid sphagnum moss: the carbon dioxide emitted won’t hurt the plants at all, but the resultant salts will burn their roots.

Now, if you know for an absolute fact that your sand is pure silica, then feel free to use it as you see fit for any carnivore soil mix you choose. However, considering the problems I mentioned before, testing it beforehand is a good option, especially if the sand would otherwise be unusable. Carbonate-contaminated sand can be treated with acid, such as vinegar, to dissolve the carbonates, but it’s generally not worth the cost unless the sand has special colors that need to be preserved. The project at hand requires:

  • a sample of the suspected sand
  • a small bottle of common household acid (white vinegar is the easiest to obtain, but ascorbic acid, also known as Vitamin C, works well, too)
  • a small container with a sealable cap, such as a single-serving yogurt container or a 35mm film canister
  • To start, get a handful of the sand and spread it out in your palm. Look for larger particulates within the sand and note the composition. If these pieces appear to be quartz, feldspar, or other components of granite, these bits should be safe. If the larger particulates include bits of limestone, sandstone, or shell, consider how many pieces you find and their size. If the sand contains lots of these chunks, don’t buy it or use it.

    Secondly, take a small amount and put it into the container. Soak it down with the acid and watch the reaction. All-silica sand won’t react in the slightest to most household acids, and typical contaminants will spit and hiss a bit. If the sample produces lots of bubbling, particularly a froth, don’t use it, as the sand is far too alkaline to be safe for use with carnivores.

    This test won’t work for other potential contaminants: for instance, it won’t test for salts. In that case, the only option is to wash it well with pure water.

    If the tested sand is the only available option, and you literally have no other choices as to sources for sand, otherwise unsuitable sand may still be used. The first step is to sift the sand with a wire mesh trainer or riddle to remove large particulates. Afterwards, put the sand into a waterproof container such as a Rubbermaid tray or a plastic bucket and add vinegar or ascorbic acid, stirring repeatedly until the mix stops bubbling. Drain off excess liquid when it stops bubbling and add more acid; keep repeating until you get no further reaction whatsoever. Wash the sand well, and spread it out to dry.

    Now, considering the work necessary to make that bad sand usable, see the advantage to using the right sand in the first place? More importantly, are you willing to risk the health of your carnivores on unsuitable sand?

Projects: “Bathtub Luffas in a Bathtub Fit For Gin”

In the Northern Hemisphere, the absolute sign of winter is the proliferation of seed catalogs in every gardener’s mailbox. Gardening resources resolutely remain in the early Twentieth Century, and while most seed companies have extensive online resources, the print editions still fill my mail drop by the long ton. This isn’t a complaint, by the way: even the catalogs I can’t use get passed on to friends and coworkers who can, and most end their lives as source material for grade school collages and band flyers.
Many better writers than I have made fun of the inadequacies and creative embellishments found in seed catalogs and on seed packets. At the Triffid Ranch, I often laugh at the catalogs that sell Venus flytrap and pitcher plant seed as if they can be planted in the garden alongside the lettuce and carrots. Likewise, the last time I saw anyone selling saguaro cactus seeds for “easy” propagation of a plant that needs twenty years to grow to a meter in height, I laughed so hard that milk came out my nose. This was especially entertaining because I was drinking Pepsi Max at the time. Some people’s definition of “easy” is another’s of “wanting to hang the copywriter by his/her ankles from a tree branch, get a few cricket bats, and play Viking Piñata for a few hours.” And then you have the minor aggravations, such as the missing step in raising luffa squash.

Luffa squash (Luffa cylindrica), for the uninitiated, is a very versatile squash for many occasions. It grows very quickly in warm climes, so it does wonders for overgrowing ugly fences and other yard eyesores during the summer and fall. The thin vines grow one leaf and three tendrils at each vine junction, so they’re much more likely to grow to great heights on tree bark and other rough-textured surfaces, and the tendrils don’t damage the surface, so they come off readily after the first serious freeze in autumn or winter. (In Dallas, for instance, they generally keep growing all the way until Christmas if given the opportunity.) Luffa leaves don’t have stomata on both sides of the leaf, like pumpkins or summer squash, so they thrive on heat that would kill most other squash. They produce large yellow male flowers that both attract bees and bumblebees and can be stir-fried after they drop from the plant. The squash fruit themselves apparently taste like zucchini, and so long as the roots are in slightly acidic and rich soil, a typical vine will produce dozens over the growing season. (I understand that they can bee cooked or eaten raw like zucchini, but since I simply can’t handle the taste of squash, I haven’t had the courage to find out.)

It’s the mature fruit that gives luffas their main draw, though, and anyone wanting a decent supply has to save a few from the crock put or wok. Instead of decaying into a mushy pulp in winter like most squash, the luffa dries out like a gourd, but without a hard outer shell. Underneath the skin is a lattice framework of fibers, which are much prized as natural scrubbers. These are most famed for their bathtub and shower attributes, especially for those needing serious exfoliation, but they also come in handy for scrubbing nonstick pots without damaging the finish, adding texture paints to walls, or removing algae from fishtanks. Small ones can be used as short-term filters for many liquids, and the big ones can be sliced up and embedded in soaps. It’s quite the versatile little squash, which makes it a particular shame that most seed packets and garden guides leave out one important step in its processing.

To begin, for those wanting to raise luffas, get your seeds, either from luffa-growing enablers or from a commercial seed catalog. Luffa seeds, if kept in the refrigerator, remain viable for as much as five years, so don’t worry about getting them into the ground right away. In fact, you want to wait until outside low temperatures exceed 15.55° C (60° F) and then plant them, because they won’t even think of sprouting before then. Luffas generally tolerate a wide range of soils, but make sure to keep potash and fireplace ashes away from the seedlings or they’ll be permanently stunted for the season. Luffa seeds are best sown directly in their permanent location, as they don’t transplant well, but they’re very vulnerable to attacks from sowbugs until they get their first set of real leaves. I’ve found that sowing the seeds and then dumping large quantities of coffee grounds atop them not only gives them the slight acidity they seem to like, but also gives the sowbugs an alternate food source that keeps them away from the squash until they’re large enough to repel attacks. Other than that, water them regularly, especially in particularly hot weather, and the luffa will start producing its first male flowers within three weeks of sprouting and female flowers about a week later.

For the most part, luffa seem to be reasonably immune to most pests, and they attract hunting wasps to the flowers, which usually take care of caterpillars and other potential pests. For those with gardens in suitable habitat, luffa vines produce excellent habitat for climbing lizards: here in Dallas, one stand of luffa can support a whole harem of anole lizards (Anolis carolinensis), so long as pesticides aren’t used in the area. The lizards hunt, sleep, and bask within the vines, which usually grow thick enough that they offer suitable cover against birds, snakes, and other predators. In return, they clear out sucking insects and other potential threats.

The only serious pest attacking luffas is easily recognized by its long bushy tail, big eyes, and a brain the size of a pea. As the luffa fruit matures, squirrels converge on any luffas they can reach and gnaw through the vine before carrying them off. Since treerats are the antithesis of grace, and since luffas readily grow into trees, this means that the little klutzes get one or two bites out of the squash, lose their grip, and watch it fall two stories or more onto the hardest ground the squirrels can find. As with dropped nuts or peaches, does this mean that the little vermin climb down and eat the dropped luffa so it doesn’t go to waste? Of course not: the monsters instead go for another easily obtained luffa, leaving the dropped one to rot until it’s joined by a few more. (There’s a reason why I consider the term “squirrelly” to be fightin’ words.) Thankfully, luffa vines are thin so as to allow easy reach of thin branches and other precarious locales, so many fruit grow unmolested at the tops of trees before dropping when they’re good and ripe.

Okay, let’s assume that you had a good crop of luffa over the summer, and not all of them ended up in stirfry meals for grateful friends and family. You want a batch of potscrubbers and buttscrubbers, but you want to make sure that they’re at the height of ripeness. What do you do now?

The harvesting of luffa squashes for scrubbing purposes honestly depends upon the growing locale and the length of the season. Pick the luffas too early, and you’re likely to end up with a moldy, rotting mess. Peel them too early, and you’re likely to spend five times as much work cleaning them as you would when they were ready. The problem is telling whether they’re ready.

The absolutely guaranteed way of telling if luffas are ready for harvesting is to wait until they shrivel, brown, and dry out at the end of autumn. This is great in warmer climes, but it’s not practical in, say, Canada. However, the best thing to do is wait as long as possible before a killing frost damages the squash, or until the main plant takes responsibility for cutting off its offspring.

Ripe luffa

Ripe luffa

In the above photo, we have a mature luffa. For the sake of what comes next, the left side, with the length of vine still attached, is the tail. The right side, still bearing the scars from where the flower was attached, is the head. The uncleaned fruit will also be referred to as a luffa squash, while “luffa” is reserved solely for the internal structure alone. Remember these, because these become important later.

The easy way to ascertain if a luffa is ripe on the vine is to grab it at the head end and squeeze gently. It should feel like a skin over an empty framework, which is exactly what it should be. If it’s still squishy, or if it feels overly heavy, then it’s probably unripe. If you can help it, leave the luffa on the vine and don’t mess with it for at least another month. If an impending killer frost is on the way, though, then remove it from the vine, leaving about six inches of vine at the end. If the tail end of the luffa is already going brown, particularly at the junction where the tail connects to the vine, then it’s already drying, and is usually ready to be picked at the time. If that junction is still green, then leave that section of vine to assist the squash with its drying. Do NOT, under any circumstances, cut the vine flush with the tail, because you’ll likely set off mold and rot at the cut.

Dried luffas

Dried luffas

In this picture, you see two ripe and dried luffa squash. The upper one dried out in the upper boughs of a pecan tree all autumn, and the scars on the surface are from where it bumped into tree branches while it was still green. Don’t worry about those scars, because the impacts usually don’t effect the quality of the luffa within. The bottom one was dried after being picked from the vine, and note the spots of mold on the shell. These need to be watched, because small spots of mold usually won’t be a problem. If it’s a big patch, or if it appears to be sinking into the squash, then the mold might be spreading through the body of the squash. Sometimes this is all right, too, but with early-picked luffa squash, this could lead to the whole squash rotting if it’s not dealt with.

As a sidenote, you might have some luffa squash with damage such as cracks or bruises, especially when the local squirrels decide to liberate them and they fall a story or two onto the cold, cold ground. Trying to dry them will just be a waste of time, so open up the squash at the crack or bruise and take a look at the interior. If the interior is hollow or if it shows extensive stringy understructure, go directly to cleaning it. If it’s still relatively solid with a white pulp reminiscent of cucumbers or zucchini, just dump it in the compost pile. It’s too green to develop any understructure, and all it’ll do is turn into a slimy mess if you attempt to save it.

If your luffa squash are already dried, then just put them into a bag or basket and leave them alone until you’re ready to clean them. if they’re still green, then set them in a warm place with good air circulation and let them dry some more. That good air circulation is vital, because if they don’t get it, the squash WILL rot. Not “may”: WILL. I speak from experience, as the only thing worse than cleaning that aforementioned slimy mess out of a laundry room or water heater closet is the smell from that mess. Leave them out on a counter, or put them in a room under a ceiling fan, and leave them alone for a few weeks. Check up on them every couple of days, and watch as they shrink and brown.

Luffa ensemble

At this point, if your luffa vines were in decent soil and had plenty of climbing options, you should have anywhere between one and thirty dried luffa squash ready for cleaning and preparation. For that, you’ll need:

  • One bathtub or washtub, preferably one needing a good cleaning
  • One bottle of shampoo (brand doesn’t matter, and sometimes the cheap stuff works best)
  • One bowl or other container for catching seeds
  • Grubby clothes
  • Goggles or an eyeshield, to keep squash pulp out of your eyes

If your luffas are extremely dried, you’ll note that peeling the skin from the luffa is almost impossible. Greener squash are easier to peel, but they need lots of washing afterwards. Either way, take advantage of the need to clean your bathtub. I have the unfortunate habit of cleaning my tub about the time it starts to resemble a scale model of the Mississippi Delta, so it’s time to fill up the tub about halfway with hot water.

In the interim, if you know anyone who wants to raise luffa squash next season, you’ll have to gather seeds. Break off the end of the head of the squash and hold the end over a container. You’ll hear the seeds rattling, so just keep shaking gently until the seeds stop falling. Always open the squash at the head, because the luffa can sometimes get so narrow that seeds can’t escape out the tail end. Gather up the seeds and put them into bags, or put them into a jar and place them in the refrigerator until spring.

Once this is done, dump your squashes into the bathtub, and let them soak for a while. The reason why you cracked open the head was also to allow water to enter the squash, making the job easier. If you’re particularly industrious, feel free to pour hot water into the opening, but otherwise you’re going to have to wait for a while. (This also applies to luffas picked green, as you’re going to need to wash off the mucilage off the luffa before it’s usable.)

Luffas before soaking

Luffas before soaking

Once the squash has been soaking for a while and the skin is soft, punch your thumb through the skin at the tail, getting it between the luffa and the skin. Work your way up to the head, and peel back the skin. Once it comes free, set it aside for the compost pile and grab another one, because if your luffa plants were remotely productive over the year, you’re going to be busy.

Peeled luffa

Peeled luffa

At this point, your tub should be full of peeled luffas. It’ll also be full of seeds, as a lot of seeds were caught up in the luffas and unable to escape until you removed the skins. Don’t worry about them in the slightest, because you’ll have to deal with more.

Post-peeled luffas

Post-peeled luffas

Disgusting, isn’t it? This is why I recommended using a dirty tub, because you’re going to have to clean it anyway.

Now here comes the important part of the whole cleaning. The dry luffas are going to be full of dried mucilage, which will leave everything they wash with a nice coat of slime if it isn’t cleaned in advance. The green luffas have just as much mucilage, but it’s combined with starches and other compounds that also prevent the luffa from being used for cleaning. Start by grabbing that bottle of shampoo and pouring a good dollop of Aussie, Paul Mitchell, or your brand of choice right on the first luffa. Massage it in, rinse it off in the tub, and do it again. Do it with the next one, and the next, until all of your luffas are nice and sudsy.

Next, put on your goggles or faceshield and grab a luffa by the tail. Picture yourself as Thetis dipping your son Achilles into the River Styx to give him invulnerability and give that luffa the same grip. Next, picture yourself discovering that Achilles is going to dedicate the rest of his life to writing term papers on Firefly and Twilight, and bash the hell out of the luffa against the sides of the tub. Go to town, and don’t worry about the seeds and bits of pulp flying everywhere: that’s why you’re wearing eye protection. When you’re reasonably sure that you’ve removed every seed (and you’ll be able to feel them inside the luffa), scrub the luffa again with shampoo and grab the next one. Repeat the cycle, as Thetis apparently had a lot of kids planning to study Pop Culture in college.

Once you’re done with taking your frustrations out on your luffas, rinse them well, and set one tail-up into the tub drain. Drain the tub, and note how the luffa acts as a filter to prevent seeds from getting into the drain. Most of these seeds are inviable, so you’re within your rights to scoop them out of the tub and dump the whole mess into the compost pile. If you’re feeling particularly adventurous, spread out the mess where you plan to plant luffas next season, cover them with a good thick layer of coffee grounds and compost, and wait to see if they come up next year. Rinse off the luffas with clear water and set them aside to dry. Feel free to give them away to family and friends, or just settle for using them for cleaning the tub. See, I told you that it needed a good scrub by now.

Now, as with any horticultural advice, these steps may be modified or arranged in any fashion whatsoever, at the discretion of the luffa farmer. You do have to admit, though, that this is still a better guide than those seed guides, right?

Projects: “Surviving the Cube”

Now for a subject of some seriousness. We’re going to talk about “The Cube”.

For those in the carnivorous plant business, as well as with more advanced hobbyists, “cubes” refer to the prepackaged carnivores sold in hardware and home improvement stores’ garden sections. The name comes from the use of clear plastic boxes to ship and display plants, usually with three varieties of carnivore with diametrically opposed growing conditions all jammed into the same space. The boxes are an absolutely brilliant way to ship pitcher plants and sundews with a minimum of wasted packing space. Unfortunately, they’re not a good permanent living solution.

Before I start, I want to emphasize that I’m not opposed to the cubes on principle. I wouldn’t have been drawn into keeping carnivorous plants had it not been for finding a display stand full of them at a Home Depot while I was buying poplar boards for bookshelves. I still have one Nepenthes hybrid, provenance unknown, that started from one tiny plant purchased from that display stand. When I was first starting as a carnivore evangelist a year later, I was also buying up the severely discounted carnivores, at least the ones that were still alive, and rehabilitating them to give to friends. Again, cubes aren’t a permanent living solution.

The problem with cube carnivores isn’t just that they’re impulse purchases, intended with as much longterm concern for their well-being as anything else sold by the cash register at the local hardware store. It’s not just that they’re usually incredibly stressed plants by the time they’re put on display, and following the recommendation to “keep the top on your plant” usually means that it outgrows its space if it doesn’t cook in direct sun. it’s not just that the collections of flytrap, cobra plant, and lance-leafed sundew will die in a matter of weeks even under the best circumstances unless the plants are separated, and that the “growing tips” on the side of the cube have no information whatsoever on how to do this. It’s that even grocery store orchids come with better information on growing and repotting requirements than a typical cube carnivore does, and that the friendly and helpful people at your local hardware store mean well, but they have next to no correct information on feeding them. (I’ve made lots of friends in the home improvement store garden sections over the years, and I know that they suck up correct information on raising carnivores like sponges if it’s available to them. Unfortunately, Venus flytrap sales volumes are minuscule compared to roses or peach trees, so there’s no incentive from the store manager or the chain’s corporate offices to make sure they have that information.)

It’d be easy for nursery operators to tell customers “Don’t buy cube carnivores,” but I know that it’s not that easy. I think of the number of beginners who are given cubes for their birthdays, or the students who figure that one of those cubes would make a great science fair project. I also understand the urge to collect a few of those cubes when they’re on deep discount and attempt to rescue the plant inside, because I still succumb from time to time. I’m not helping convince the local Lowe’s store manager not to order more, but there’s no reason for the plant to die in order to stick with your principles.

The trick to freeing a carnivore from the cube is to understand what it is and what it needs. Sarracenia and Nepenthes pitcher plants are really bad choices for the cubes, as they get far too big far too quickly to last very long, and they often die of shock even if put into optimum conditions right away. Darlingtonia plants generally die even if they’re transplanted right away into those optimal conditions, and they usually only last a few weeks without the root disturbance. Especially if kept inside, there’s simply no way that a Venus flytrap can get enough light for proper growth in a cube, and that’s doubled if the flytrap has bugs or hamburger shoved into every trap. Butterworts and sundews need more air circulation than what’s available in cubes. Ironically enough, many terrestrial bladderworts would do better than most in a cube, so long as the cube doesn’t dry out, but I’ve never seen a bladderwort in a cube, probably because they don’t have obvious above-ground traps to attract buyers. As for other carnivores, they’re either too obscure to draw interest from anyone other than specialists (Byblis), require specialized light or temperature conditions that are almost impossible to replicate easily in a home center greenhouse (Cephalotus), or have trap structures too small to appreciate without a magnifier (Stylidium, Genlisea). The vast majority of cube plants are going to be either flytraps or pitcher plants of one sort, so let’s start with a pitcher plant.

Behold: the cube

Behold: the cube

Now, let’s look at the problems with this arrangement. Unlike cubes of days past, where the plants were shoved in the bottom amidst a handful of barely damp sphagnum moss, this one at least is in a plastic pot for drainage, but that’s the only good news. This poor Sarracenia has been in this cube for a long time, as demonstrated by the number of leaves jammed up on the top of the container. The condensation gives a good idea of the relative humidity inside of the cube, meaning both that poor air circulation has a good chance of promoting disease and fungus. Worst of all, most of the leaves are winter leaves, known as phyllodia, with tiny or nonexistent traps at the end, which means that the plant hasn’t been getting anywhere near enough light since it was first potted up. It may not die immediately, but it’s going to die soon, which may help explain why this was marked half-off at my local Lowe’s store.

Before cracking open the top, having the right equipment and supplies is vital if the plant is going to survive. These requirements include:

  • A suitable amount of carnivorous plant potting mix and distilled or rain water
  • A suitable pot, with sufficient drainage and ability to retail moisture at the same time. (For this exercise, we’re going to use a ProlitariPot for clarity.)
  • A sharp pair of utility scissors or a sharp knife
  • A plastic bag large enough to go over the plant and the pot
  • At least one thin bamboo stake or dowel rod, preferably treated to resist moisture (orchid stakes work best, but chopsticks will work in a pinch)
  • A indirectly bright windowsill or greenhouse space for recuperation

The top of the cube

The top of the cube


The first thing to do is pop open the top and see if the patient is able to be saved. Most cubes are taped shut, on top of being sealed in plastic wrap and pressure-sensitive stickers, partly to keep the cube contents in and keep meddling kids out. Examine the cube to see where the cube opens, and with the scissors or knife, cut open the various adhesives.

The cube opens

The cube opens


In this case, we have what’s probably a Sarracenia hybrid, but it’s hard to tell what kind with the way the traps are stunted and misshapen. As mentioned before, most of the leaves are phyllodia, and it’s going to be a while before it has the chance to grow any proper traps. Just getting the top open, though, is a start, and the way the leaves popped out when it came off gives an idea of how badly it needed the room to grow.

Removing the spacer

Removing the spacer

Depending upon the nursery that supplied the cube, the plants are held in place with a variety of options, such as plastic film, rubber bands and wires (seen only once, thankfully), and plastic inserts. This one came with a plastic spacer, with two wings that come in contact with the underside of the lid. The pitcher plant comes up through a hole in the spacer, and often grows over it. This spacer needs to be removed very carefully to prevent damage to the crown of the plant. If this requires grasping the leaf bunch to keep them together while pulling them through the spacer hole, do so, because any damage to the leaves in grabbing them is going to be minor compared to scraping and cutting from the sharp edges of the spacer hole.

The spacer removed

The spacer removed

If recycling facilities exist in your area for plastics, set the spacer aside for recycling. Otherwise, just throw it away. It won’t be needed again. The same goes for the cube itself, unless your idea of an exciting weekend involves polishing scratches out of Plexiglas.

The still-potted but uncubed plant

The still-potted but uncubed plant

The pitcher plant is going to look even worse once it’s removed from the cube, as the traps are too weak for most to stand upright. The good news is that it came out of the cube just in time: the humidity may have been high enough, but note that the soil mix was nearly completely dry.

Bottom of the pot

Bottom of the pot

While the example isn’t the greatest picture ever taken, note the bottom of the pot, and the root growing from the bottom right. This plant was in the cube for a good long time, sopping up available moisture from the bottom as water vapor leaked out the seams in the cube lid. When repotting, try to pull roots like this through the drainage holes without damaging them if at all possible. If the roots are too thick, or if they’re so extensively intertwined that they can’t be separated, use the knife or utility shears to cut them just enough to get them through.

The plant in its old pot

Now it’s time to decant the plant from the shipping pot. In this shot, note the original traps growing when this plant was shipped, especially when compared to the subsequent phyllodia. This plant will make it, but it’s going to need a lot of care.

Bagged carnivore

Bagged carnivore

Without disturbing the root ball, remove the original pot and put the root ball into the new pot, filling the gaps with fresh carnivore growing mix. Water it down well to get the roots rehydrated and to help settle any air pockets. Take the bamboo stake (in this case, a spare orchid stake) and put it in the edge of the pot, with at least 5 centimeters of clearance above the highest trap. Place the plastic bag bottom-side up over the pot and the plant, helping to keep up the level of humidity the plant had in the cube while giving it more air circulation than before.

Finally, here’s the important part. Place the pot, plant, and bag into a well-lit space where it will not be exposed to full sun for no less than two weeks. Repeat: do NOT put the plant in full sun, as it will likely burn until it adapts to life outside the cube. Just leave it alone, making sure to add additional water if absolutely necessary.

At the end of that two weeks, remove the plastic bag and move it into better light. With sundews and Nepenthes pitcher plants, be careful not to give them full sun right away, but good partial sun is perfect while letting them get acclimated. Sarracenia pitchers and Venus flytraps need as much light as they can get. If growing conditions are right and the plant’s time in the cube wasn’t too debilitating, you should see new trap growth within two to three weeks. The existing traps won’t grow further or straighten out, but they’ll act as an essential photosynthetic resource for new traps. As the old traps brown and die off, snip them off, and encourage the new growth to spread up and out. It may take a year, but given decent growing conditions, it won’t be too long before the carnivore that was languishing in its cube is in full form, growing and even blooming.

Again, this isn’t intended to be a slam on the cube plants themselves. However, considering the effort necessary to nurse an ailing cube plant, isn’t it easier to deal directly with a nursery that specializes in carnivores than wrangling with cubes?

Projects: “Capsicum Peppers for Bonsai”

Interested bystanders considering moving into bonsai have multiple reasons to be dissuaded from giving the art a chance. Many, particularly Americans, are put off by the amount of time necessary with many tree species for initial training. Others don’t feel comfortable with risking a valuable scion or yamadori to a design that might kill the tree. Still others feel intimidated by the techniques themselves, and wish for easier starter plants for practice before risking a pomegranate or Wollemi pine to shaping and cutting. In recent years, herbal alternatives to standard trees, particularly using rosemary and other woody shrub herbs, have achieved a popularity of their own, and an intriguing alternative is the Capsicum group of peppers.

The advantages to using Capsicum peppers for bonsai experiments include a higher resistance to dehydration than most other bonsai candidates. Since hot peppers cannot tolerate temperatures below freezing, they must be kept as indoor plants in areas with such temperatures, and the peppers thrive as indoor plants in sunny locations. Many, such as the jalapeno (Capsicum annuum) and the habanero (Capsicum chinense), produce attractive flowers and fruit as bonsai. Best of all, not only are plants suitable for bonsai available at garden centers and nurseries, but no evidence yet exists for exactly how long they may survive with proper care. Anecdotal evidence of jalapenos and habaneros surviving for as much as thirty years in plants brought in over the winter, but since most plants stop producing peppers at about that time and are subsequently composted, a Capsicum bonsai may live considerably longer than this.

Another advantage to using Capsicum peppers is that as the pepper plant ages, it builds up a woody stem that is very easy to cut and shape with standard bonsai techniques. The following project involves the beginnings of training a pepper plant for bonsai, but be aware that as with most bonsai, the final effect will take years of shaping. Using Capsicum peppers for bonsai is much faster than using comparable-sized trees, but proper techniques still require patience.

And now the safety warning, to keep the lawyers happy…

WARNING: When using hot peppers for bonsai, ALWAYS wear protective clothing when working with ripe or green fruit. While the leaves and stems do not contain capsaicin, the active compound in hot peppers that produces the distinctive fire, the fruit will, no matter what stage of growth. Some individuals are particularly sensitive to capsaicin on the skin, and all must take precautions not to get any in the eyes , mucus membranes, or particularly sensitive skin. Especially when working with notedly hot peppers such as habaneros, eye protection is highly recommended, as mild bruising of fruit that otherwise leaves no trace may still leave enough capsaicin on skin to cause extreme burning if it gets into the eyes. ALWAYS wash your hands and tools after working with Capsicum fruit, whether it is green or ripe. Neither the Texas Triffid Ranch or any of the entities therein take responsibility for any injuries or discomfort caused by exposure to Capsicum fruit, and individuals overly sensitive to capsaicin should attempt the following project using a mild pepper, such as the TAM jalapeno or habanero developed by Texas A&M University.

To begin, suitable peppers may be grown from seed, or may be purchased as seedlings from the aforementioned garden centers. A suitable pepper should have a good rootstock and a stout stem. Always examine a candidate pepper for infestations of pests such as aphids and whitefly: an infestation at this early a stage suggests a weak plant, although this could also be a factor of poor growing conditions.

Upon finding a suitable candidate plant, the first concern is training it for future shaping. Capsicum peppers are particularly adapted to hot and dry conditions, and in fact have problems with root rot if kept overly wet. My preferred choice of training pot is a five-inch pot purchased at a garden shop sale, with a lip on the drainage saucer to allow inspection of the water level. Make sure that the crown of the plant, where the stem connects to the roots, is not buried in the repotting, as this may cause stem rot and may kill the pepper. Water the pepper sparingly and only when the soil is completely dry, and fertilize every six months. As the plant responds to conditions, it will produce small leaf pods, which may be shaped later.

After six months to a year of growth, the bonsai candidate will have reached the limits of growth in its original pot. In this case, the plant shifted to the side and produced new growth along the leading edge. Several small offshoots have died back at the tip, and these may be used as deadwood or jin in the final design or removed later. The main stem now shows signs of becoming woody, and while whitefly or aphid infestations may cause localized leaf loss, new leaf clusters will appear from the trunk so long as the trunk itself is still green. In addition, while the plant was stressed, it still produced a full dozen fruit and as many flowers at the time this picture was taken, attesting to the strength of the plant. Both flowers and fruit may be removed at this time, taking care with the fruit, or they may be left intact when repotting.

Of particular note is the root system in the pot. Capsicum peppers do not seem to respond well to exposing the roots for long periods, so trying to develop a nebari may cripple or kill the pepper. However, this may be only a condition of a young pepper plant, and anyone wishing to research this on an older pepper should not be discouraged from doing so.

At this stage, the root system has filled the entire pot, meaning that it already has a sufficient root pad for repotting in a traditional bonsai pot. Try to choose a bonsai pot as deep as the root pad, as the root pad will not respond as well to root combing as other bonsai candidate species. As with most others, place a piece of nylon screening over the drainage holes to prevent soil from escaping through the bottom.

At this point, the pepper is ready for repotting. The workspace used for repotting depends upon the individual, and I use a plastic container to minimize soil escape. Use this opportunity to examine the root pad for potential diseases, but try to keep disruptions to a minimum. Excess roots through a drainage hole may be trimmed, but try not to remove excess soil or comb roots for shaping.

Actually stabilizing the root pad may use several techniques, all of which depend upon the individual artist. Peppers respond well to tying with wire through the drainage holes, but in this case, the only support is the soil itself. Note in this picture that the pepper stem itself extends well beyond the confines of the pot: once it is adapted to its new pot, the trunk may be propped to a shankan form, or the excess trimmed to encourage the new growth within the pot for a penjing display. This, as always, depends upon the form of the pepper and the demands of the bonsai artist.

As of this writing, the only addition to this planting is a broken pot used to assist the roots in keeping the pepper in its original leaning form. The pepper is watered when dry, which is usually once per week, and has been kept out of direct sun during that transition. The next stage involves improving upon the branch shape and encouraging a stronger root system, and the final results should be completed within the next six months. Since so little information is available on using peppers for bonsai, copious notes have already been taken on this bonsai’s development, and the techniques described herein will be applied to other habaneros to confirm that these work the best.

The use of Capsicum peppers for bonsai candidates may be unorthodox, but future experimentation should confirm that their use offers opportunities for expanding the art. Their quick growth rate, their unusual leaf and fruit structures, and their ability to thrive under dryer and hotter conditions than most bonsai candidates give them a decided advantage to beginners, and advanced bonsai artists may find much to work with from this particular genus. As always with bonsai, the important consideration is giving the plants time to show their best advantage.

Postscript: shortly after finishing this article, I discovered a Finnish chile enthusiast who does his own pepper bonsai. He’s at least five years ahead of me, and has already demonstrated that pepper nebari are both possible and impressive, which means that it’s time for me to get to work.

Projects: “The ProletariPot”

Back in 2007, horticulturalist and indoor plant specialist Bob Hyland offered instructions for converting a standard 2-liter soda bottle into a sub-irrigation planter he called a Volksplanter. While his design was very ingenious, I needed to do a few modifications to optimize its use for carnivorous plants. I jokingly called it a “ProletariPot” as an inside gag dedicated to the British comedian Alexei Sayle, and the ProletariPot has proven itself to be an excellent replacement for standard plastic pots. Besides being extremely cheap to manufacture, the ProletariPot encourages deep root systems, conserves water, and facilitates easy cleaning and reuse. Most of the Texas Triffid Ranch’s carnivores are raised in ProletariPots, with deep-rooting plants such as Venus flytraps particularly enjoying the improved drainage. With a bit of modification, or a return to Mr. Hyland’s original design, a ProletariPot could be used for propagation, overwintering, dormancy chilling, seed starting, or any other need that potentially requires an inexpensive container.

The list of materials

Making a ProletariPot requires at least one washed 2-liter soda bottle with cap, a sharp knife or pair of scissors, and an awl or other sharp pointy thing suitable for making holes in plastic. (If you’re doing a lot of them, a drill fitted with at least a 1/4″ bit will make things very quick.) If an awl is unavailable, and I find that the awl in most Swiss Army knives is perfect for the job, then a hammer and a large nail will work just as well. Optionally, a black Sharpie marker is handy but not absolutely necessary. Each ProletariPot will also require a cup of horticulture grade perlite, and the soil mix of your choice.

Although it’s a love-hate relationship, this is my favorite: Pepsi Max. No calories, decent flavor, and enough guanara extract to raise the dead. The Elixir of Life for anybody working in a tech job with lots of overtime and not enough sleep.

Preparation
The first step in preparation of the bottle is to strip it. With the knife or scissors, cut the label off the bottle. For best results, use bottles with plastic labels that can be peeled off, as paper labels glued by their entirety to the bottle will dull your blades.

After discarding the label, it’s time to poke a hole in the cap for drainage. You have the option of removing the cap and punching a hole with a hammer and nail, but I’ve found that using a Swiss Army knife’s awl produces a perfectly sized hole for our needs. (Again, with lots of bottles, you’re better off using a drill.) When doing it this way, make sure that the cap is securely affixed to the bottle, so that the air pressure inside the bottle keeps the bottle from collapsing.

After punching the hole, replace the cap if you removed it, and make sure that it’s on the bottle as securely as it can. Squeeze the bottle to force out the air inside.

Squeezing the bottle

Pick a place on the bottle about one-third up the side from the base and cut across the bottle with the knife or scissors.

Cutting the bottle

Cutting the bottle.

The idea is to cut the bottle at such a point where the top of the bottle can be nested inside the base, with the cap in the bottom. You want to cut the base high enough that the edge of the base will support the weight of the rest of the ProletariPot and the top doesn’t pivot on the cap, but not so high that the cap doesn’t rest on the bottom.

Proper nesting of top and base

At this point, the basic pot is ready, but still requires soil and plants. If you want to label the ProletariPot, particularly if you plan to use it for starting seeds,do so now with the black Sharpie.

Adding soil
At this point, the Proletaripot is ready for use, and all that’s necessary is an appropriate growing medium. First, though, add a cup of horticulture-grade perlite to the bottom: this will allow drainage while also allowing capillary action to draw up moisture from the bottom of the pot. I find that pouring the perlite is improved by using a Rubbermaid pitcher to pour it, as the plastic will trap excess dusts without spreading them in the air. You do NOT want to breathe perlite dust, so use a mask and try to do this outdoors if possible.

Pouring perlite

Next, add the soil mix of your choice. My preferred mix for carnivores is a 50/50 blend of pool filter sand and shredded sphagnum peat, with enough water to give it the consistency of a good mud pie.

Filling a ProletariPot with soil mix

Add the plant of your choice, add more soil mix to fill the space between the plant and the walls of the ProletariPot, and water it well. Within about a minute, you’ll see water collecting in the base of the ProletariPot, and this will act as the pot’s reservoir.

Collections
Single pots get the job done, but anyone with a dedicated collection of plants may need a way to store the pots while still allowing air circulation between them. Interestingly, most soda bottlers developed a perfect solution, if it’s available to you.

ProletariPot and carrier

ProletariPot and carrier

Now, a quick warning and notice. The bottler carrier shown above was being thrown out by a local liquor store, and any retailer who carries 2-liter soda bottles will probably have more in the back or behind the building. Depending upon local law, taking these without permission may constitute theft. For instance, Texas law makes the unauthorized collection or possession of plastic milk crates a prosecutable offense. While bottle carriers aren’t as versatile as milk crates, many distributors return the carriers to a soda bottler for a deposit, and unauthorized harvesting of carriers may be prosecuted. If all else fails, ASK FIRST: if a retailer gives permission to clean through a stock of carriers, it’s usually because they were being thrown away.

While bottle carriers help assist with supporting ProletariPots, they aren’t necessary, as the base is already designed to help a bottle heavier and more unstable than the final project stand upright in pantries and refrigerators. So long as you aren’t worried about aesthetics, the new pots can be used indoor or outdoors, and can be modified further, such as becoming the core of a macrame pot hanger. In the meantime, try one for propagation and another for seed germination, and enjoy the results.
