Fertilizing Tips
- When planting, do not put fertilizer in planting hole.
- When fertilizing, water or rake in the mixture evenly under the entire canopy of the tree, avoiding a 4-inch area around the trunk.
- Fertilize no more than 2 times each year, beginning in March and no later than July. Fertilizing after July may promote new growth around the time the plant needs to go dormant.
- Premature fruit drop and the spread of fire blight can be caused by over fertilization.
