The common honey locust, Gleditsia triacanthos, is a deciduous tree that can grow up to 100 feet tall. Honey locust blooms in late spring with small but fragrant cream-coloured flowers. It grows well in a variety of soils, but prefers a site with full sun exposure. A honey locust must be pruned regularly when it is becoming established, to maintain its health. Regular pruning also can help shape the tree. Prune honey locust trees in late summer or early spring while they are dormant.
Remove all dead and dying branches from the honey locust tree. Cut all the way down to the main stem with sharp pruning shears.
Cut all branches that cross the centre of the tree and inhibit light from reaching another branch. Trim any lower branches to help shape the honey locust's crown. Prune the limbs using one quick cut. Do not saw at the branches; this can encourage disease.
Thin out the branches when they become very crowded.
Prune a honey locust until it is a few years old. Pruning isn't required after the tree has become established.
