Acacia trees make up a large genus of trees with almost 800 different species. Varieties of acacia trees are native from North and South America all the way to Africa. Different species of acacia can grow from 25 to 40 feet tall, with a 25- to 35-foot spread. Most acacia trees are hardy only in warmer regions, from USDA zones 7 to 11; and most are either evergreen or semi-evergreen and need pruning to grow strong structures.
Remove all but the strongest branches when the tree is young, 2 to 3 years old, at the base of the branch.
Remove any dead, damaged or diseased foliage from the acacia tree at the base of the branch. Cut off the foliage with the shears if the branch is thin or the saw if it is thick.
Remove any drooping branches or branches that make it impossible to walk under the tree. Remove the branches at the base of the branch with the saw.
Remove any crossing branches or branches growing vertically at the base of the branch with the saw. Cut back any over-reaching branches to within the canopy with the shears.
