Composting is a super way to enrich your soil. There is no exact recipe for making good compost and anytime is the right time to start your own heap.
Many different things can go into the heap as long as it was a living thing at one time.
Grass clippings, leaves, sawdust, wood ashes, weeds, twigs, hay, vegetable peelings, egg shells and even coffee grounds can all go into your compost heap. Don't put in fat or meat scraps. The first step is to decide where to put it. Pick a spot out of the way so it won't be disturbed. A bin that keeps your composting materials all together is also a good idea.
