This indicates that aeration is inadequate. The volume of the compost heap needs to be large enough to insulate itself in order to maintain the heat of microbiological activity. A cubic metre or slightly larger is sufficient size. You may need to sieve your compost through chicken netting prior to use. Any stalky or coarse material removed is then recycled into your next compost heap.
Compost gives newly planted trees and shrubs a good start.
Mix 1 or 2 buckets of compost into the soil prior to planting. Keep compost in the backyard and out of the waste stream.
