Pruning is the removal of living plant tissue to stimulate growth, remove dead tissue, or reshape a shrub or tree. There are several types of pruning cuts including heading cuts, thinning cuts, and pollarding. When to prune depends on the type of plant, with spring flowering plants pruned after blooming and summer flowering plants pruned during dormancy. The proper tools, such as pruning shears, lopping shears, and hand saws, should be used depending on the size of branches being cut.
