🗓️ When to plant
Plant bare-root or container trees in mid-spring after the last frost, or in early autumn in mild climates to establish before winter.
🌰 How to plant
- Choose a sunny, sheltered spot with well-draining soil and dig a hole twice as wide as the root ball.
- Place the tree so the graft union (if present) sits 5 cm (2 in) above soil level.
- Backfill with native soil mixed with compost, firm gently, and water deeply.
- Mulch around the base (avoiding the trunk) to retain moisture and suppress weeds.
💧 Care
- Prune lightly in mid-spring to maintain shape, remove dead wood, and improve air circulation.
- Fertilize in early spring with balanced fertilizer; established trees need minimal feeding.
- Water regularly during fruit development in summer, then reduce watering in autumn.
- Provide winter protection in cold climates with frost cloth or grow in containers moved indoors.
- Thin fruit in early summer if trees are heavily laden to improve olive size and quality.
🧺 Harvest
Pick olives in late autumn to mid-winter when they shift from green to black, or harvest green earlier for a firmer texture. Use a fruit picker or gently shake branches onto tarps; fresh olives require curing before eating.
🐛 Common problems
Olive fruit fly: Monitor with pheromone traps from late summer; spray neem oil or insecticidal soap if infestations appear, and remove fallen fruit promptly.
Peacock spot (fungal disease): Improve air circulation, avoid overhead watering, and spray copper fungicide in humid conditions during growing season.
Scale insects: Spray horticultural oil in late winter before bud break, or use neem oil during growing season if populations increase.
