Do not fertilize during the first growing season. Young
trees benefit from light applications of nitrogen fertilizer.
Apply about 0.33 pound of ammonium sulfate per tree per
year. Keep the fertilizer at least 18 inches or farther
from the trunk and water well after application. As trees
mature, increase fertilizer to up to 5 to 7 pounds of
ammonium sulfate per tree per year. The ideal time of
application is during the dormant season.
- 1st growing season—Do not
- Young trees—1 to 2 oz actual nitrogen
- As trees mature—Apply 1 to 1.5 lb
