The Q&A Archives: Apple and Peach Tree Fertilizer

Question: I planted a peach tree and a apple tree. I want to know what I should use to for fertilizer.

Answer: A healthy apple tree grows 6-8 inches at the tip annually. If it does so without added fertilizer, you don't need to apply any. Fertilizer levels are calculatd for young trees or mature trees. Typically, gradually increasing amounts are added for 3-6 years, then it levels off for the mature tree. For example, 1/4 pound of 10-10-10 is applied just as buds break in the spring. Increase the amount by 1/4 pound each year to a max. of 2.5 pounds for a dwarf variety, 5 for a mid-size, and 10 for a standard variety. These are approximates and should be adjusted for your situation.

Peaches are heavy feeders and need regular applications of fertilizer. For young trees, apply 1/2 pound of 10-10-10 per year of growth. For mature trees the max. is 5 pounds. Again, apply in spring as buds break.

Always water thoroughly before and after applying fertilizer and expand the application zone out to the tree's drip line or canopy.
