The main principles of compost making a

1) Mix the heap well. Don't have more than about a 3 inch layer of new grass cuttings, don't have more than a 6 inch layer of twiggy stuff.

2) It loses heat through the outside, so make it is big as possible, but maximize the volume to surface ratio - ie a cube rather than tall and thin.

3) Water it if it's too dry. Ants = too dry

4) Ideally, have the base standing directly on soil so earthworms and other organisms can get in. Otherwise, chuck a layer of soil in on top of the first layer of green stuff.

You don't need more than 3 heaps, one filling, one maturing, and one being used. And you can get by on two. If you've got lots of small containers, then amalgamate them into fewer bigger heaps.

If you have a lot of grass cuttings, then have a storage area for either grass cuttings or more twiggy stuff (whichever works best for you), so that you can interleave grass cuttings and twiggy stuff on the heap.
