This great composer has the added benefit of coming in a shocking shade of pink, you can get the same green benefits without sacrificing style. (Of course, it also comes in the regular black-ish compost bin color.) Anyway, your compost materials go in the top of the drum, and you can turn the drum easily to aerate and mix. It’s available in a 17-gallon or 35-gallon size, and it also comes in black if you prefer a less conspicuous look. Fans of watering plants with compost tea (water steeped in compost) will be delighted that the base is designed to collect it for you.
