I need to clarify one point. My brand new outdoor compost tumbler does not include worms. They need an environment between 55°-80° and wouldn’t survive the winter in New York. Outdoors, the right combination of greens, browns, air and water + time will result in compost. Adding worms just makes the whole process go a lot faster and makes vermiculture (fancy, for worm compost), ideal for the indoors because the food waste is broken down so quickly that (when it is working correctly) it has no smell. I can attest to that because for years, our bin was in our kitchen (literally 2 feet away from our dining table) and no one could ever tell. We once had a dinner party where the topic came up and when I showed our guests the hidden compost, one visibly blanched. I’m still trying to convince him that worms are awesome, but I guess they just aren’t right for everyone.
We have had a couple of worm bins on and off for the last 14 years. Back in 1998, the Brooklyn Botanic Garden ran a composting workshop and I decided to check it out. I had no idea that worms were to be involved, but the process seemed so interesting (in a home science project kind of way) that I found myself lugging a bin full of worms through Prospect Park that same afternoon. Our early attempts weren’t without some setbacks, however, the biggest issues being mold and fruit flies. Ugh. Little did I know that banana and citrus peels come teeming with fruit fly larvae just looking for the right conditions to make it into the world. Our bin was their Shangri-La and they seemed impossible to get rid of. At one point, we had to dump the whole thing and start over. Another problem was mold when the bin got too wet – that was easy enough to remedy with shredded newspaper. Luckily, I had the helpful reference guide, “Worms Eat My Garbage” by Mary Appelhof:
Slowly we got the hang of it and – being just two people at the time – the compost did a pretty good job of handling our food scraps. A few years later, though, we found ourselves moving into a smaller apartment with no logical space for a worm bin to go. We kept meaning to get one but got wrapped up in a whirlwind of babies and subsequent moves. By the time we came around to it again just a few years later, worms had moved from being the weird kid you don’t want to hang out with to the sort-of cool kid you might be friends with. More people had them and - even better – there were a wider variety of bins on the market. Once we settled in what we hoped to be a long-term apartment, we immediately went searching for something that would fit into the only space we had (which happened to be smack in the center of our living room/dining room / kitchen). Because of this, I wanted to make sure that I had a handle on the fruit fly situation, so I attended another workshop, thus beginning my love affair with the Lower East Side Ecology Center. Unlike the first workshop I attended, this one was crammed with people all eager to get their hands on some worms and the crowd included a reporter from the New York Times who ran this story on the growing popularity of vermiculture in NYC. I brought my daughter along and she ended up being the cover model for the article which she will either grow to love or hate a few years from now.
The workshop walked everyone through setting up a bin and was helpful in enlightening me to a few ways to improve my system: for one, I hadn’t been using enough shredded newspaper bedding which is what was keeping the bin too moist. Most importantly, I learned that if you freeze (or microwave) your food scraps before adding them to the bin, you will kill the fruit fly larvae! It works like a charm. Not one fruit fly darkened our bin since.
So now that you are convinced that this awesome, how do you get started? Well, there are a multitude of resources on the web that will walk you through the process, but this is what we did:
Suddenly, you are composting! Feels good, right? This description is just my experience, but for more comprehensive guide to setting up a bin, take a look at this handy reference from (you guessed it!) LESEC.
Next week, I will talk about when and how to harvest the compost from your bin.
