Koroneiki oliveKoroneiki is a Greek cultivar grown primarily for oil. The tree has medium vigor with a spreading, relatively open canopy and produces small fruit that ripens later in the olive season. Fruit quality and harvest timing vary with climate and care.This potted tree is intended for warm growing areas. Plant it in full sun and freely draining soil. Although established olives handle dry periods better than many fruit trees, regular irrigation during establishment is important.Pollination and harvestOlives are wind-pollinated, and fruit set depends on cultivar compatibility, bloom overlap, weather, and tree condition. Koroneiki may set fruit alone in some conditions, but a compatible cultivar such as Mission or Hojiblanca nearby may improve fruit set. Harvest timing depends on the desired oil style and local conditions.Planting and careChoose a full-sun site with excellent drainage. 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. Mature size, flowering, harvest timing, and crop size vary with climate, tree age, pruning, pollination, water, and care. 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.
