Shortly after planting, apply 8 ounces of 10-10-10 per plant. Do not place fertilizer in the planting hole. In subsequent years, broadcast 1/2 pound of 10-10-10 under each tree in the early spring. Increase the amount applied by another 1/2 pound per year, up to 5 pounds per tree regardless of age. Maintain pH at 6.0 to 6.5. Never fertilize after July 15.
