Mix two or three times a year to speed decomposition. Shredding coarse plant material will make it easier to mix and speed up decomposition. Bacteria also need moisture. During dry weather, it is wise to add water to the pile. With more care, it is possible to compost organic waste in about two weeks.
Leaves are difficult to decay.
If they are used, mix one part leaves, one part other plant residues, such as grass clippings, and one part manure. All coarse material should be chopped or shredded. Water the heap thoroughly. The mass should start to heat within 30 hours. If it doesn't, add more manure or one-fifth pound urea nitrogen per bushel of heap.
