Available in two styles, pruners are essential for trimming shrubs and bushes, deadheading spent flower heads and cutting back overgrown or fast-growing plants. Anvil pruners crush the plant stem, and are best suited for dead or old wood on shrubs and vines. Bypass pruner blades pass each other when cutting, and deliver clean, close cuts that are safer for living stems, vines and flowers. Pruner handles typically range in length from 6 to 9 inches, and all pruners come with a locking mechanism to keep the blade closed when not in use. Loppers are the long-handled version of pruners, used to trim small branches from trees and tall shrubs, while standing on the ground. Loppers, as with hand-held pruners, also are available in anvil or bypass style, depending on the nature of the required pruning.
