Worms Are Your Friends – Indoor Composting (part 1)

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:

  • Make or buy a bin:  You can buy a bin on Amazon, or visit sites that specialize in worm bins and there are a variety of options.  If you have a lot of space or a basement, you can actually build a large enough system to feed a family.  There are also lots of how-to sites and videos on the web that will show you how easy it is to construct your own bin.  We went with the Tumbleweed worm bin mostly because it fit into the small space we had, but we grew to love it because it is a nested-box system and allows you to drain the liquid that forms (called compost tea).
  • Get your worms. It seems you can get red wigglers anywhere these days, even on Amazon or Worms.com.  Depending on where you live, shipping worms in the winter time can be a challenge, so if you have an environmental organization in your area, contact them to see if they might be able to sell to you directly.  In NYC, you can buy worms at the Greenmarket.
  • Set up your bin –  To get started, find some old newspaper.  It needs to be a paper that uses soy-based inks, as my local paper happily does. Most papers do, but if you are concerned, you can call them and ask. Shred the newspaper into strips about 1″ wide and create a nice fluffy nest in the bin.

  • Add your worms!  Take your worms and the medium they arrived in and dump the whole lot into the bin.  Cover with more paper.

  • Add your food scraps.  A bin the size of our Tumbleweed can handle about 3 lbs of food per week.  To make sure we didn’t overload the bin (and to prevent fruit flies), each time we would cook we would add the food scraps to a container in the freezer.  Once a week, we would dump the contents into the bin.  Each time you add, put the new food in a new spot – not right on top of the food from the previous week.

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.

How To Set Up a Worm Bin

Next week, I will talk about when and how to harvest the compost from your bin.

Happy Composting!

It’s Earth Day. Time to get your compost on.

Do you like gardening?  Do you feel like you never get enough time to dig around in the dirt here in the city?  Does it bug you when you have to throw your produce scraps in the garbage?  And then does it bug you even more when your garbage starts to smell?  All of those problems can be solved by starting your own indoor worm bin.

Gross, you say?  I get that.  Sort of.  When I was a kid, every time it rained I would pick up earthworms off the sidewalk because I think they are kind of cool.  So earthworms don’t really freak me out.  If you told me I should set up a grub bin or a maggot bin, I would excuse myself from our conversation, never to return.   But worms?  I guarantee they are totally benign.  Plus, when you toss your food scraps into a worm bin, the worms start to break them down right away, skipping the unpleasant rotting food smell you sometimes get when you open up your garbage can. Yay worms!

The thing is, 26% of the trash that goes into landfills is made up of food scraps and yard trimmings.   That, to me, is more disturbing than setting up a box full of worms and dirt in your kitchen (actually, ours is in the dining “area”).  You can easily divert your share of that to the compost in a few different ways.  If you have your own back yard, there are a variety of different bins out there that are easy to order and set up (click here for some good reviews).  If you live in an apartment building, you can band together with your neighbor to start a building-wide compost program.  Last year, I attended a workshop given by the Lower East Side Ecology Center (an amazing organization, I might add) on how to convince your co-op or condo board to approve a building-wide system and how to go about setting it up.

However, if you don’t have much in the way of outdoor space, and your building is full of cranky people who are not down with the whole Earth Day thing, you can easily  strike out on your own in the comfort of your apartment.  The fanciest way to go about doing this would be to order the NatureMill Automatic Composter from Williams-Sonoma.  It looks like a little composting robot and appears to do everything for you.  It does recommend you keep it in a garage or sheltered outdoor space, so I don’t know what that means for apartment dwellers.  If it wasn’t $400, I would buy it and report back (if you have one, I would love to know about it).

Another option is to go the Bokashi route.  Bokashi composting uses a combination of anaerobic organisms (like yeast and lactic acid bacteria) to break down food waste.  Sounds like making yogurt.  I’ve been curious about this for awhile and am planning to buy one,  especially since it claims to break down meat and fish scraps (which are a huge no-no for most compost bins).

If either of those options don’t work for you, consider an indoor worm bin.  It doesn’t take up much space and is fairly easy to maintain (as in, you don’t need a compost-sitter when you go on vacation). We have had a bin on and off for more than a decade.  I first learned about vermiculture through a workshop at the Brooklyn Botanic Garden in 1997 and started it as a domestic experiment; one that really did freak people out.   Flash forward to 2011 and you have worm composting featured in a Martha Stewart publication.

While worm composting is extremely easy, you do have to keep a few things in mind.  One bin can only handle about 3 lbs of scraps per week.  We monitor the amount by freezing out scraps in a container and adding them once a week.  You do have to peek in the bin on a regular basis to make sure it isn’t too wet or dry and to make sure you have a nice ecosystem going on in there.  That is my kid’s favorite part – they have names for them.  About 3 or 4 times a year, you have to harvest the compost.

In the coming weeks, I will document the harvesting of my current bin the and setting up a new one on this blog.  If you are itching to get started right away, check out the LESEC‘s instructions, or this step-by-step guide.  It will be fun and I guarantee you will not be sorry when you see the amazing soil you are adding to your plants (or to the trees on the street for that matter).

Happy Earth Day!
