Dig a hole no deeper than the root ball and wider than the container. Set the tree at the same soil level it had in the pot, backfill with native soil, and water thoroughly. Keep the root zone evenly moist during establishment without leaving it waterlogged.Prune lightly to develop a balanced canopy and remove dead, damaged, or crossing growth.

Container-grown trees require more frequent irrigation and periodic root and canopy management.Olives are bitter directly from the tree and must be cured before eating.
