Just added to the g_space roof top farm equipment is this small electric chipper mulcher. Its makes the work of composting all the leaves and stalks from tomato plants, broccoli, and other plants with tough stalks much easier.
Under $200 this electric mulcher is well worth it. I chopped up these broccoli stalks in a half hour. It will even chop up the roots when i fed the into the top. It took most of a day to cut up all the tomato stalks by hand for composting.
The top accepts leaves and twigs while the side has a chute for branches up to 1-3/8″ in diameter.
