Fertilizing Olive Trees

Fertilizing Tips

  • Do not fertilize after August or before March.
  • Do not allow any type of fertilizer to touch the trunk of the tree, as the high levels of nitrogen can cause burns.
  • Feed your olive tree small amounts of fertilizer several times a month and water well after application.
