While visiting with my friend Elisabeth and her family, we helped make taco salad for supper. I chopped up some peppers, habitually making a little pile of the trimmings for the compost pile. I asked her where she was keeping her compost bucket and she answered, a little guiltily, that she didn’t compost in the winter: too much trouble.
I was surprised, as she and her husband are probably the thriftiest, low-impact kind of people I know, but I understood completely. Who wants to trudge outside through the snow? And really, who can call that frozen pile thawing to sogginess in spring a pleasure?
Coming home, I realized I should have told her about the worm composting I was trying out. Or, was supposed to be trying out but in reality was repeatedly forgetting about and then trying to repair the neglect. And then I remembered that I had promised you, dear reader, an update on my progress! Well, here you are. Here’s what I’ve learned.
I have two worm composters: a Worm Factory and a Worm Inn. My second Worm Factory went to my sister Jenni. In retrospect, I probably could have kept it to keep up with the volume of kitchen waste around here (assuming I could find a place for it). As it is, I am still taking some larger loads outside to my regular bin, especially during harvest and canning. But Jenni finds the Factory to be a good size for her household of 2.
When I say I need to “repair the neglect,” there really is more guilt in my heart than travesty in the bin. My worms don’t mind being fed once a week, though I try to give them little bits, more often, rather than lots at once. It definitely makes a difference if you chop up stuff into smaller pieces. This improves breakdown in regular composting, but it’s doubly true for the worms. They say you can feed worms anything as long as there’s no grease, but I’ve found a couple of exceptions in practice and reading: they don’t seem to eat seeds. I’ve had several sprout on me, including cantulope and pumpkin, and my otherwise finished compost is littered with them. They leave tougher stuff like stems from squash alone, and they don’t like raw potatoes. Go figure. And no matter what you feed them, always bury it with some bedding to discourage flies and mould.
Speaking of, the “ick” factor is much lower than I thought it would be. There is no smell (unless I over feed and under bed), and the worms keep to themselves. I had some fruit fly trouble once, but a trap placed nearby took care of them within two days. My biggest mess factor: bits of shredded paper or coconut fiber always on the floor. It seems impossible for me to get a handful into either bin without scattering a bit.
I did break down and bring both units into my back entry for the winter. Once the temperature started to drop, they just weren’t eating in the garage.
As far as the bins themselves, I think I prefer the Worm Inn for design and ease of use. It’s easy to add material to the top, and harvesting is as simple as opening the bottom and draining it until you see bits of unfinished food or some worms. I also love the space-saving hanging design, and it holds way more than you would imagine. The major drawback for me is how good the airflow is, meaning, I actually have to remember to check the moisture level. Dry worms=dead worms.
This is the big plus for the Worm Factory. Moisture loss is not a problem; however, too much moisture can be. I leave the drainage spigot open with a bucket under it all the time to try to help the airflow, and I definitely use more bedding compared to the Inn to try to absorb the moisture. I have to be sure not to add too much food at once or it goes slimy before the worms get to it. (I should mention the Factory I have is an older model, and the newer ones look like they are designed for better aeration.) Also, the trays are pretty heavy when full of damp material, and the finished compost always seems to still have worms in it, so you have to sift them out or help them migrate by placing the tray in bright light.
Dig around a little and you’ll find many other composter designs, including ones you can make yourself. But the basics are the same: Keep them aerated, keep them damp, keep them bedded and keep them fed. Is it more work than traditional composting? Maybe, but I don’t have to trudge through the snow, and I’ve got fresh compost all winter long. Whatdayathink, Liz?
