Like pruning, mulching and feeding your fruit trees will keep them healthy and productive. Mulch your trees after planting and every spring and fall thereafter, taking care to leave room right around the base of the trunk. (Mulch piled high around the base of the tree can lead to rot).
The best time for pruning fruit trees is at planting and in subsequent years, in early spring before buds break and trees are still dormant. Pruning should be undertaken at planting time where you cut the new stem off 24 to 30 inches (61-76 cm.) from the ground and remove any side shoots.
