Prune dead wood and crisscrossing branches in late winter after the hard freezes end. Use pruning shears, lopping shears or a pruning saw according to the size of the branches to be removed. Prune dead branches back to live wood. Prune crisscrossed branches back to the live stem. Cut off the weaker branch.
Prune old branches from the bushes in late summer after harvesting the fruit. Look for branches over 1 inch in diameter and cut them off. This makes room for fruit-bearing new shoots. Use the lopping shears or pruning saw to cut the old branches close to the stem.
Snip off the suckers or water shoots growing from the base of the plant unless you want additional stems. Do this in late summer. Trim twigs and branches of the plants as needed to shape them and keep them from sprawling over walks or shading other plants.
