• Trees 1 to 2 years old, apply 1/4 cup fertilizer per tree.

• Trees more than 10 years old, apply 2 to 3 cups.
You can also use nitrate of soda (16-0-0) but double the rate, Upham says. If a soil test calls for phosphorus and potassium, use a 10-10-10 but triple the rate.
“On apple trees, last year’s growth should be 8 to 10 inches; cherries should have 10 to 12 inches; and peaches should equal 12 to 15 inches of terminal growth,” Upham says. “If less than this, apply the higher rate of fertilizer, and if more, apply the lesser amount.”
Spread fertilizer evenly on the ground away from the trunk of the tree and to the outer spread of the branches, then water it in, Upham says.
