Watering. Olive trees prefer deep but infrequent watering to encourage strong roots. Allow the soil to dry out between waterings to prevent root rot.
Fertilizing. Feed olive trees with balanced fertilizer in early spring and mid-summer to support healthy growth and fruit production.
Olive trees are fairly tough and drought-tolerant once established but need plenty of sunlight and well-draining soil. They can suffer from root rot if overwatered and may attract pests like scale insects. Pruning is needed to maintain shape and encourage fruiting.
