We recently moved to a new house, and along with leaving our garden (insert a little tear and sniffle), we left our compost bin. While we’ve built a new garden that is going gangbusters already in one season (I am quite proud of this progress), we have not yet replaced our composting system. After several years of learning how to compost everything possible—kitchen scraps, garden waste, fallen leaves—it feels wasteful and just weird to not compost. So now that the garden is kicking, it’s time to turn to choosing a new composting bin. But I’m not sure yet whether we’ll DIY or buy (BIY).
At our previous house, we had a stacking black plastic bin in which we added kitchen scraps and discarded plants from the vegetable garden. (Only ones without signs of disease, of course — anything diseased should be trashed so it doesn’t infect the compost.) The black retained heat and kept the compost warm, while the stacks let airflow in, creating a good system for quick compost that, with a little turning and materials adjustment every now and again, was ready in a season or two.
Our bin was purchased, but a similar DIY setup involves using reclaimed wood shipping pallets to make a compost bin. My only caveat on this is that wood absorbs moisture and not sunlight, so you’ll need to make sure that your compost bin has the right amounts of water and heat.
The one-bin system worked well for us as beginners, but I think we’re ready to graduate to a larger more sophisticated system this time around. The spinning composters intrigue me, in part because I think they look kinda cool and also because it would eliminate the need for me to use a pitchfork to turn the compost. While I will invent reasons to use a mattock, a pitchfork isn’t really my favorite tool.
I personally would only consider a plastic or resin composting system if it were made from recycled materials. After all, recycling is the whole point of composting. This high-capacity compost tumbler is made from recycled resin, so it fits the bill. It also—genius!—includes a reservoir for harvesting compost tea, an all-natural plant food made by steeping compost in water. While there are other methods for brewing compost tea, I’m intrigued by the idea of incorporating the process into my compost bin. (Note the air holes on this tumbler, too. This is very important! A friend, who shall remain unnamed, recently told me that he just puts his scraps in a plastic trash can with no holes. This is NOT a good idea, folks. Compost needs air, or else it’ll just become a sludgy mess.)
A DIY three-bin system also looks like a good option, and it’s where I’m leaning right now. I’ve seen these at several gardens I’ve visited over the years, and it makes a lot of sense because you can keep compost organized in three stages of decomposition: fresh scraps, compost in process, and compost ready for the garden. This video shows the basics of how to make a three-bin compost system using wood and wire mesh.
What about all you other composting fanatics out there? Tell me about your composting system, whether DIY or BIY, and help me decide.
