What would the visible effects on a Maple (Inaba Shidare) that has been over fertilized ? I transplanted it in June and have been giving it 15-30-15 soluble once a week . The leaves that are starting to come out at the top seem very small and burn easily . The lower leaves came in the lower part of the tree are healthier and larger and are not getting sunburnt . Would overwatering cause this ??
