Olive trees are long-lived, shallow-rooted, slow-growing evergreens. They are perennials in zones 8-10 (15-22 degrees Fahrenheit).
Scientific name: Olea europaea
- Average mature height: 30 feet high and 25 feet wide
- Container growing: Choose a large pot that's about two feet in diameter and has good drainage. Prune the tree to size.
- Fertilizer: Fertilize March through August. For container growing, use a slow-release fertilizer.
- Light: Plant in the sunniest spot available. Olives do not tolerate a lot of shade.
- Soil: Free-draining soil that is never soggy is best for olives. They are drought tolerant once they are established.
