Compost!

Here’s just part of the second load of dark gold this season.

I know composting is warm and fuzzy and poetic, all about returning the earth’s bounty back to the soil. But take a look at the mechanics of composting, will you?

You prune your garden and throw the scraps in the composter. Or you find plants that have died and chop up their remains into the dark bin. Next you wait a few months for the stuff to break down and then you feed it back to the plants in the garden. Some of the plants might be seedlings of deceased plants in the compost. It’s like you’re feeding a plant the reprocessed remains of its parents or–worse yet–itself.

In human terms you’d call this something close to cannibalism, not far from what happens in the 1973 science fiction thriller Soylent Green. It had been a few years since I’d seen the film so I had to refresh my memory of its plot: Charlton Heston plays a prickly detective named Thorn. (Thorn, as in “thorn in your side” or Thorn as in something botanical–my conspiracy theory is coming full circle…)

In the course of investigating a murder, Thorn happens upon the realization that the rations many of the residents of 2022 New York City were eating–Soylent Green–were reprocessed from humans, hence the famous penultimate line from the film, “Soylent Green is people!”

We’re all civilized folk, however, so cannibalism isn’t something that we generally take part in. (And for me it’d be doubly difficult because I’d have to give up being a vegetarian…)

Still, all unseemliness aside, I’m getting hooked on vegetable cannibalism–composting–and I’m feeling good about it.

Kitchen scraps, most of the garden clippings, all these things end up in the big black bin. The first batch of Soylent Black took about six weeks in high summer. The next batch got close to ready but then I fed the composter lots of new scraps, pushing back the time it would be ready to use by a couple months.

And then in October, with what passes down here as heavy autumn rains, a large branch that constituted about a quarter of the grapefruit tree snapped. It seemed like a waste to toss the unripe fruit, so into the composter it went. Four or five weeks later it looked like this, with most of the whole fruits looking almost like the day they were admitted to the composter.

So to the list of foodstuffs like avocado pits and corn ears–things that don’t break down readily–I’ve added whole citrus. By contrast the fruits that were broken open were beginning to compost, so I fished out all the whole uncomposted grapefruits, split them open with a shoved, and then added them to the next pile of things to start composting.

One of my mother’s Ohio-isms was the phrase that someone’s eyes were bigger than their stomach. In our case it was that our pile of compostables from an intense weekend of clearing our overgrown plants was bigger that the space we had in the barrel.

But no problem, really. We chopped these up into two big yard trash cans that will sit around for a couple weeks, maybe a little more in this cold weather, until the volume of what’s in the composter now miraculously shrinks. (If you’ve composted you know exactly what I mean, with the compostables seeming to turn into water and vapor, leaving almost nothing behind.)

You may be looking at this and saying that it’s a lot of work, and it can be. But like so many other things in the garden, it’s amazingly gratifying work, both for the gardeners and the lucky plants that get a share of the soylent black.

my new composter

I often get the impression that to get your ticket punched as a real, serious gardener you have to take up composting. Still, I gave up on polishing my halo a dozen years ago. The old-fashioned compost pile I had took way more maintenance than I was interested in…all the hassles, especially keeping the beast stirred and watered.

Since those days tumbling composters have really come into their own as an alternative to the piles that just sit there like Uncle Ervin on his Barca-Lounger in front of the TV. The promise of a compost device that simplifies keeping the mix stirred and aerated sounded almost too god to be true, but I’ve been tempted to give them a twirl.

The opportunity came up as I headed to the back aisles at Costco to pick up some cheese and bread. On my way to the back of the store a big tumbling composter tried to reel me in with its dark tractor beam.

The thing with this store is that you usually have your choice of the one item they offer for sale, which in this case was the 80-gallon Lifetime model 60021 tumbling composter. (Costco offers several other models online.) Even with a price tag less than $100 I resisted at first. But I went home and did a little research online. Judging by the customer reviews people generally seemed to like this model, with the main complaint being being about an internal aerating tube that kept getting bent because it was made out of PVC. It seemed like a valid but relatively minor concern, so I decided to give the composter a try.

The composter in its box, as it looks when you bring it home.

When you buy this model, you’re really buying a composter kit, not an assembled composter. I documented the time I started, before I opened the box, before I assembled the necessary tools (which ended up requiring–among other things–an electric drill and socket wrenches), before I read the instructions that recommended that it would take two adults to assemble it. John is still hobbling around on crutches right now, so I decided to go it alone.

The time right before I began to open the box.

From the documented end time you can see that it took me about an hour and fifty minutes to put it together. That includes time spent taking a few pieces apart after I’d installed them incorrectly, as well as a few minutes when John came out to supervise my work and ogle the new toy. I’m generally pretty handy with mechanical things, if a little impatient to read all the way through instructions. I also did okay hefting the big 65 pound box the kit came in, and had the added benefit of a power screwdriver. Adjust your expectations for assembly time and effort accordingly.

Things fit together easily and made for a sturdy, double-walled, insulating composting chamber. Apparently the company read the customer complaints about the PVC aerating tube, because by the time they made my version of the model, the flimsy internal part had been replaced with a rigid piece of perforated metal pipe.

I couldn't resist doing a little trimming of plants around the garden. On even its first day, the composter is well on its way to being filled. The cuttings and kitchen scraps will cook down over time, making room for more waste.

The composter now lives outside the kitchen, alongside the trashcans and recycle barrels. It shouldn’t be hard to keep the compost barrel fed and tumbled. Once the barrel is filled it’ll need a few weeks for the compost to cook to perfection, a time when you shouldn’t be feeding it more clippings and scraps. To do things right, having a second barrel at the ready for those times would be the way to go. Within a few weeks I should have a better idea whether this model of composter lives up to my expectations and warrants my buying a second one.

So, will I become a real, serious, composting gardener? I’d say it’s off to a good start.
