Healthy soil is the key to healthy plants. Healthy plants have no need for fertilizers, pesticides, herbicides, or fungicides, which kill worms. Worms provide healthy soil, etc. Composting is the best way to handle our organic waste, and anyone can do it, from the condo resident who produces one small bag of the stuff each week to the farmer who needs a tractor to pile it up. Selection of a compost bin is the first step.
Numerous designs are available, most through mail-order and a few at local hardware stores.
A heavy-duty garbage bag will work in pinch. Gathering the organic materials is the next step. If you want to build a large, active pile that heats up, works quickly, and turns in to brown gold in a month, you're going to need a lot of material - at least enough to build a pile or fill a bin with minimum dimensions of 3'x3'x3'. If you're more interested in a passive pile, one that works slower but eventually creates usable compost, you can start now and add organics as you get them. Either way, the smaller the pieces that go into the pile, the faster they'll compost.
