Growth Stages

Establishment

First 6-12 months

Young tree with woody stems and silver-green foliage; developing root system

Water regularly for first 6 months to establish roots. Mulch around base (2-3 inches) to retain moisture. Stake if needed in windy locations. Protect from freezing temperatures.

Vegetative Growth

Year 1-3

Tree increases in height and branch structure; narrow, lance-shaped leaves; silver undersides visible

Prune to shape and remove crossing branches. Light fertilizing in spring with balanced fertilizer. Continue deep watering during dry spells. Thin interior branches for airflow.

Flowering

3-4 weeks in late spring

Small, inconspicuous creamy-white flowers appear in leaf axils; flowers are wind-pollinated

Flowering occurs in late spring (May-June in Northern Hemisphere). Provide light pruning only. Do not over-fertilize with nitrogen. Ensure cross-pollination by planting near compatible olive cultivar if possible.

Fruit Development

5-6 months (June-October)

Small green fruits develop from flowers; fruit gradually enlarges and changes color from green to deep purple-black

Thin fruit if over-crowded (remove 30-40% of fruit for larger olives). Reduce watering slightly to concentrate sugars. Apply potassium-rich fertilizer. Protect from excessive wind that may drop fruit.

Harvest & Dormancy

September-February harvest; dormancy 2-3 months

Fruit reaches full dark purple color; tree enters winter rest period with minimal growth

Harvest when fully black and slightly soft. Handle carefully to avoid bruising. Allow tree dormancy in cooler months (reduced watering, minimal fertilizing). Prune after harvest if needed.

Companion Planting

Plant with:

Rosemary Lavender Thyme Sage Pomegranate Fig Almond

Avoid planting near:

Black walnut (juglone toxicity) Plants requiring frequent irrigation (incompatible water needs) Shade-producing trees (olives need full sun)

Common Pests

Use pheromone traps; prune affected fruit; apply spinosad or neem oil in late summer; remove fallen fruit promptly
Spray dormant oil in winter; prune heavily infested branches; introduce beneficial insects like ladybugs
Improve air circulation through pruning; apply copper fungicide in autumn; avoid overhead watering
Spray with water to dislodge; apply neem oil or horticultural miticide; increase humidity
Prune out infected branches 12 inches below visible symptoms; sterilize pruning tools; apply copper-based bactericide

Harvest Tips

Harvest fruit in late fall (October-November in Northern Hemisphere) when fully dark purple and slightly yielding to gentle pressure. Olives can be picked at any stage—green for a more bitter flavor, fully ripe for milder, buttery taste. Use careful hand-picking or gentle shaking onto tarps to avoid bruising. Handle gently to prevent oxidation. Harvest can begin after 3-5 years, but full production takes 7-10 years.
