Fly Paper




Sorry, couldn't resist the joke: Repulsive's on ScienceDaily.com Or his kind, anyway. Industrial-scale black soldier fly larvae processing: 20 million steroid-abusing maggots in their articulated armor chomping their way through a literal ton of organics every day.

Repulsive to the nth power. Still, nice to see someone trialing alternatives to burying organics in concrete-lined pits!

This year's hands-free tomato garden was supposed to be rather more ambitious than last year's, but I got discouraged. Early in the spring, I built three small (4'x2') raised beds, filled them with dried leaves and soil and a little wet organic matter, dosed with AEM, covered, and let rest. Two of the three worked well, so I did get to plant some tomatoes--but the third was invaded by fire ants.

The cover wasn't well secured, and I hadn't bothered with weights, so it was my own fault; next time I'll know better. But that was no help for this time! Couldn't re-cover it, with the ants only too willing to defend their home, not that I was sure it would have helped. I don't do chemicals, flame is too risky for our persistently drought-ridden climes, and I didn't want to pour great quantities of water into the bed to try to chase the ants away, so I decided I'd disturb the ants every chance I got and just build another bed for the next tomato planting.

Stirred some odds and ends of half-decomposed material into the infested bed while I was disturbing the unwelcome resident ants, since I don't yet have a proper compost bin at that location. And a while back, my odds and ends included the last crumbles of cheap bagged soil that had sat around in a dampish corner.

A bag one of these Texas Blind Snakes had adopted for a home.

Scared me silly--but I'd already emptied the bag into the bed, and the worm-colored scaly snake had slithered beneath the leaf-mulch, so that was that. Stirring up the ants did not appeal at all that day, or for the next few weeks; didn't bother to water the bed, either, as that would have meant standing too close to it.

But I'm a gardener with only limited space, and the presence of a raised bed full of largely composted matter eventually proved too great a temptation. So I grabbed the longest-handled shovel to poke around...

And discovered what would not have been news to anyone who'd bothered to look up the Texas Blind Snake instead of just squeaking like a small child and running away. Turns out, this wormy-looking snake eats ant and termite larvae. Not a single fire ant came out to attack the shovel, no matter how vigorously I stirred the bed. The materials are not wholly composted, but it's far enough along for my purposes. With or without a worm-snake, though I hope not to see it when I'm planting.

Wearing gauntlets as well as gardening gloves, I think. -G- Not that the worm-impersonating snake would hurt me, but I'm squeamish.

Introducing Nigel




The vermi-family has grown: I have African Nightcrawlers now. Actually, have had for a couple of months, though not many to speak of at first...so I didn't. But now Nigel's a definite presence.

The image above, from localharvest.org, is nothing at all like the material I started from. Local bokashi-and-beyond purveyor Microbial Earth offers an "African Nightcrawlers & humified compost mix"--according to the label, approximately 200 to 300 cocoons packaged with coir and compost for direct-to-garden application.

My vermigardening's mostly containerized, so I potted some herbs with a little of this mix added in, and set up a planter tower after my usual practice but without any actual worms, just the cocoon-and-compost stuff.

Well, in the interest of accuracy I should mention the two or three thread-thin hatchlings I found in the bag. But no breeding populations, you understand.

So at first, I assumed the worms I saw in the new tower were volunteers from the established colonies. But African Night Crawlers (ANC) are larger than the others. Much larger. When, on lifting the tops off two worm-homes, I saw worms in one that were twice as large as those in the other, I knew Nigel had established.

Still not quite as impressive a tangle as that image, but he's expanding quickly enough that I'm planning to divide him this weekend--probably a little soon for that, but he's just so big. It looks like he's cramped for space.

Haven't yet found any in the olla pots, so he may be brighter than Verne (EF). Or maybe it's the size thing again, or age; it tends to be larger, presumably older, iterations of Verne who move comparative mountains to get into the damp, cool clay containers between waterings.

So far, no vermi-battles have been observed. Verne mostly stays in his containers; Cousin Clem (Indian Blue) wanders a bit, but Repulsive (BSFL) has claimed all the good spots, so he retreats to the undersides of saucers. George the earthworm (no idea, possibly more than one species), sniffs around wherever any excess bokashi juice or Repulsive effluent has been diluted and applied, and sometimes finds his way into a recently wetted planter to become the worm equivalent of the crotchety old man in the corner house. "Hey, kids! Stay out of my burrows!" Or so I assume from the occasional vertical airspace in some of the less-tended and more populated units.

Nigel has yet to make his way out into the larger world. Which, you understand, is just fine with me! Worms that large disturb me a bit; I'll be just as happy never to encounter one without advance warning.

Though he's certainly welcome in the garden.

How many buckets would that fill?




From the text on the poster--details and a gallery can be found at GrowNYC--I'm assuming that little if any of this collected material is composted; clean dry and paired suggests reuse, not reclamation. And that's great! But what about filthy, torn, disreputable shreds of former garments?

Let them eat cake couture.

Verne et cie happily munched their way through the post-season potato bags, not quite waiting until the season was over before starting; Repulsive's nearly through the denim I decided was too worn to save for next year's insulation, and it's only been a couple of months; there are still bits of terrycloth in the slow-compost after nearly a year, but only bits, sufficient to add a bit of structure but nothing more. And the fabric bokashi bag (filled with matured ferment and buried at planting time) was only root-tangled threads when I repotted that particular item.

It's hardly news that natural fabrics are compostable in a home setting; the trouble is that so few of us think to do it! So, I'm trying. Dishtowels and cleaning cloths, old clothing and shopping bags, bits of fabric too small to make decent patches...into the mix they shall go.

Cleaned if needed (though I'm not much for chemicals) and tossed in after fermentation, I think. Unless I'm feeling experimental. 'cause, you know, that happens sometimes.

Been reading about the soil industry lately, picked up a new-to-me-term: low value soil-like materials. Paper waste and sand and things. Bulking and structural items, to me, since for nutrients I have bokashi. Seems strange to think of silk or linen as "low value" in any way, but a stained or torn shirt is trash, so, okay.

If we each saved one shirt from the landfill...that'd be a lot of space we didn't use. But I'm selfish, I want a personal benefit. So: if one shirt could replace one gallon of soil in a planter... Yeah, that'd work for me. Soil's expensive, relatively speaking.

Anyone need help cleaning out their closets? -G-

Got K-Cups?





[sorry for the formatting—I'm having blogger issues again. Image from espressoplanet, no connection though I lost some time browsing their offerings.]

Single-serve = more packaging. I know. And K-cups are ridiculously easy to throw away, all neatly packed even after use, while being nearly impossible to dispose of responsibly.

If only they didn't make such good coffee! -G-

So the workplace now has a Keurig. It also has two Solofill reusable filter-cups, but I'm the only one who'll use those; everyone else uses the packaged cups. Before I started agitating for folks to toss their K's into the compost collector [“my worms are hungry! Please feed them your tea bags, fruit peels, etc.”], I figured I'd better make sure the foil-topped plastic cups with coffee and filter inside were, in fact, bucketable.

Turns out...they're not suitable for a standard bokashi bucket. (As a general note to myself for future experiments: Impermeable additions mess with bucket health. Treat separately if at all.) Nor all that desirable for my bucket-alternatives. Even leaving the chemical concerns out of it, plastic in a slow compost pile is never recommended; it will break down into smaller pieces, but not truly degrade. The worms don't appreciate foil, though it isn't enough to make them flee from an otherwise suitable planter, but it takes a surprisingly long while for any worm to get brave enough to wriggle into a cup, and in the meantime, other critters may decide to colonize. Bad enough having to remove slightly degraded plastic cups from your vermicompost, but a cup full of centipedes? Eek! Repulsive doesn't mind them if the foil's torn a bit, and cohabitation's far less of a concern there, but small cups can hold waer, which could stagnate, and then there's the mucky mostly-intact plastic to fish out of the grubbery. Ick. And Ugh.

If you take the foil off the top, the worms are happier, though the other concerns still apply. Sigh. I scrounged a covered tray that would fit half a dozen or so unlidded used K-cups; spritzed EM/AEM/AIM on the UCG and let it ferment for BSF bait or “breath freshener” or compost boosters—nice fermentation, but in order to use the stuff, you still have to separate the organics from the plastic. Let me just say, it's a pain: the filter's glued into place. I resorted to kitchen shears.

And gave up on trying to salvage the organics from them in any organized sense. Hey, I divert my own UCG, isn't that good enough?

...which argument would sit less uneasily on my tongue if not for the fact that the workplace Keurig is actually my personal property, installed there for office use because I could.

Oops.

...and the results are in!




Sorry for the lack of posting lately—oddly for me, I haven't had much to say! -G- Since I was low on pot-fillers and plant-foods, I went back to the processes I knew would work and shelved (most of) the experiments awhile, and “Day fourteen: bucket ready for stage two” doesn't make for interesting posts.

But it occurred to me as I was picking lavender for a fruit salad that I had written something about that plant's rooting medium soon after its potting, with no followup. So...

This is one of the plantings where I used bokashi and shredded office paper, with no additional microbial source and an extra-long curing period during cooler weather. I tossed some exhausted dirt in the bottom of the container, filled it most of the way with the paper-bokashi mix, then dug a small nest into the paper and filled that with decent potting soil, into which I planted a typical four-inch nursery start. About an inch of soil to top. No olla pot in this planter, mostly because I didn't have one ready but also because I wasn't sure the paper would hold one stable. (A later test confirmed that assumption, though it is possible to use the side of the planter as a partial support.)

Call this a very slightly qualified success I cannot currently replicate. It's a little messier than I prefer my container gardening, especially without crockery in the bottom of the planter—a step I gave up on for good when I realized that it might prevent worms from colonizing my plantings. But the muddy deposits around the base of the planter are attractive to wandering worms, many of whom then find their way into the planter, and a larger-than-normal drip tray will retain that nutrient-rich material until it can be tossed back on top or harvested for another planting.

As well as the mess, this method looks like it might require a mid-season addition of potting mix. This isn't an insurmountable problem, but I prefer to avoid mucking about with roots between repottings. The bokashi and paper seem to be decomposing both faster and more completely than I'd anticipated, and there isn't enough soil in the planter to support the plant alone. Next time, I'll add a bit of sand or some other non-nutritive material. Natural fabrics, maybe; they decompose more slowly than paper, and plants root well in them.

Now for the good parts:

No root-burn! Most of the bokashi mixes have to be cured after mixing with potting media, which is fine for more organized gardeners but a trial for me; this material was close enough to neutral pH to be safe for immediate use, and while there was likely a bit of heating, it wasn't enough to register on my low-tech tests, no more an issue than Texas sunlight if the planter was watered adequately for the plant. (A second test suggests that you really don't want to let it dry out even halfway within the first week, though I found no troubles thereafter. I'd try it again, but I'm out of “hoarded” bokashi. For now.)

No long-term odor. There was a faint but present unpleasantness upon emptying the hoarded bokashi, as there often is when emptying a bokashi bucket left to sit awhile—which is why I always do that outside—but it wasn't noticeable an hour after the planting was finished. A soil cover or some other barrier is definitely necessary lest the material attract pests, but with that one small remediation, this seems like it could be used in any outdoor setting.

No additional fertilizer needed. Bokashi's a nice sub-surface slow-release plant food; 'nuff said.

No trash. Convert kitchen waste and junk mail into produce? Sounds great to me. And this method used only “trash” and an EM source, plus a small quantity of soil for the potting, most of that re-used. Cheap and responsible, my favorite kind of technique.

The lavender was one of two plants I potted in this mix, the other being a blood-veined sorrel that's quite stunted in appearance just now. A casual observer might decide it was was overnourished and therefore feels no need to grow—look closely and you'd see signs of my too-frequent harvesting. What can I say? I grow things so I can eat them.

The garden plan having been scuttled by last fall's too-dramatic events, I joined a CSA this year to augment my produce production. Vegetables are packed in shredded paper for transport, so I thought I'd try the same slow-cure method...but it turns out that doesn't work in warmer weather here. No bokashi hoarding in Texas heat!

Maybe in an air-conditioned office?

Definitely worth further trials.

--Until the next,

DSF

Tales from the Bucket: The Stone Soup Bucket




[image from the Florida invasive plants site]

I could work up a serious dislike of chinaberry trees. Actually, it wouldn't take too much work--the fruits are poisonous, the trees sprout like weeds from seed or sucker, and they're nearly as discouraging as walnuts when it comes to plant biodiversity in their immediate vicinity. Granted, their flowers smell nice, but that's not enough to earn their keep.

Before moving to Texas, I had never encountered the term “trash tree.” Until chinaberries and scrub elm, I'd never thought to use it. But chinaberries...well, I suppose they have their place, but there are far too many of them in my limited growing space.

Porch sweepings in this season are mainly those sticky chinaberry fruits with their hard centers, plus a few dried leaves, oak pollen, unripe mulberries, and assorted other detritus. It's not a great mix, and without serious hot-composting or some intervention, the result will have so many chinaberries-in-waiting as to be more trouble than it's worth.

Unless, of course, you're short on composts, funds, and resources altogether. Or are trying to be wholly self-sufficient in anticipation of TEOTWAWKI. Or have hungry grubs to feed...

Repulsive's active laying period has begun, but I don't have all that much to give him just now. He will not eat chinaberry fruits left to decompose where they fall, but put them in a container with a seasoning of bokashi and he'll chow down! And while the fruits are toxic to mammals, they don't seem to bug him one bit. So I swept the porch-fall into a series of flat, stackable containers--shallow dishpans--and added a cup of bokashi'd kitchen waste to each one. Bokashi plus sweepings will self-compost to some degree, though not significantly in this scenario, with so little moisture or pressure. But there is enough moisture for mama layers to consider the mix a decent foodsource, and it turns out the small volume of bokashi I used as a start, plus the occasional addition of a small bit of bokashi juice or anything else in the vinegar range*, is sufficient to keep the grubs happily chomping their way through those fruits and churning the leaves toward their natural end, with the help of EM and other IMOs.

There are already saplings appearing in this mix, so apparently chinaberries don't object to dilute acids and disturbance. But they're easy to uproot now, can be tossed right back in to provide more food for microbes and macros, and if they sprout and die now then the eventual soil amendment will not have tons of saplings. It will have a whole bunch of seeds, but after sprouting they're not nearly so pebble-hard as when they're still encased. Cooked stones are a bit softer, maybe? -G-

Being rather squeamish about Repulsive, I'm still planning on aging the grub mix and/or letting the worms have it, but it looks like it should be usable to a less grub-averse gardener in about two months from sweeping, finished enough to use as container fill for an outside planting without further intervention.

And if you weren't doing retail bokashi, this would still be perfectly feasible; a purely lacto fermentation will attract BSF layers. The current favorite among non-bokashi-ing BSFL “wranglers” seems to be fermented corn. Come to think of it, chinaberries in water might well ferment...

There is one major disadvantage to my stack-of-dishpans set-up--I do not believe Repulsive should be allowed to free-range--but now that I know the chinaberries can be useful, I'll build a case or something. The minor disadvantage, that the relatively open stacks require additional moisture, I consider a trade-off, as the relatively high rate of evaporation means I don't have to drain reservoirs of grub muck. Also, the neighbor's AC unit drips more than sufficient water onto my porch, and unless you're using clay or filters, AC water is not recommended for watering plants, so what else am I going to do with it?

Goes well with the whole something from perceived-nothing idea, too.

Are your grubs awake yet? What are you feeding them?





*vinegar, kombucha, bokashi bran mixed with water, even sauerkraut brine, if it's real kraut.
