Many trees have gall or other mites that disfigure the foliage with cocks combs or nipple like lumps. These should be moved off site or disposed of to prevent re-infection. Leaf shredders are an excellent way to speed up the process of composting, mixing leaves with other vegetable waste from the house and turning it frequently will promote proper composting.
