How to Fertilize Old Peach Trees

Overview

Fertilizing your peach tree, an important part of maintenance, can yield nutritious fruit full of vitamins A and C. Even if your peach tree is old and no longer producing copious amounts of fruit (or any fruit at all), it still needs nutrition and annual fertilizing. Well-fertilized peach trees are better able to resist disease and insect infestation and cope with environmental stressors.

Step 1

Fertilize the peach tree with 1 pound of 10-10-10 granular tree fertilizer in March. Spread the fertilizer in a 2-foot-wide circular band begining just inside the drip line and extending 2 feet beyond.

Step 2

Water the fertilized area with 1 to 2 inches of water to help the fertilizer reach the tree's roots.

Step 3

Repeat steps 2 and 3 in May if your peach tree is still producing fruit. If not, but it is still vigorously growing (no less than 6 inches of new growth per year), fertilize only once annually in March.
