A composter is a great part of any garden-care tool set, and this trapezoid-shaped outdoor bin was the best one we tested. Indoor bins have a temperature advantage that can help your composting, but if you want a traditional option (or just don’t want compost inside your home) this is a great choice.
The bin was easy to add to. The opening is wide enough that you can shovel in leaves or leftover garden plants. The sides have plenty of holes for ventilation, but they aren’t fully open. They let in air and moisture and cut down on the smell, but they also keep bugs and animals out.
We did run into an issue with mice digging under the side of the bin to get to food scraps. However, we addressed it by pushing the “teeth” of the bin further into the ground and placing large rocks around the edge to keep them out. If we did it again, we’d use a few pieces of wood as a frame to make the bottom secure from the start. Flat ground works best, but you could probably get away with a bit of a slant.
Because of the trapezoid shape, the bin fits up to 65 gallons, almost double what most bins can hold. We added to the bin every few days, and even then only filled it about halfway.
While we had plenty more room, it was also nice to have empty space in the bin. The leeway let us use a thin shovel or tool to stir the pile. Since this bin doesn’t spin, we tried to move the materials inside once a week to help break up clumps and spread the heat.
Our favorite feature is the four sliding doors at the base of each side. They made it easy to check on the bottom of the pile and measure temperature and moisture levels. We also imagine it makes emptying the soil at the end of the process easy, as well. The roomy interior, multiple openings, and secure closures make this bin well worth the price.
