Young Tree (1-3 years)
3 yearsSmall sapling with developing canopy, silvery-green lanceolate leaves emerging on woody stems
Establish strong root system with consistent moisture. Protect from hard freezes with mulch. Stake if needed for wind protection. Remove competing leaders to form single trunk.
Establishment (3-5 years)
2 yearsGrowing canopy with mature foliage, trunk thickening, occasional small flowers appearing in late spring
Continue regular watering during dry spells. Light pruning to shape form. Begin light fertilization. Transition to drought watering.
Flowering (late spring, typically May-June)
4-6 weeksTiny cream-colored flowers appear in short panicles along branch tips; flowers are delicate and fragrant
Avoid heavy pruning during flowering. Light, consistent watering supports fruit set. Ensure good air circulation through canopy. Note that some years may have alternate bearing.
Fruit Development & Ripening (June-November)
5-6 monthsSmall green olives form and gradually change color, from green to yellow-brown to dark purple-black when fully ripe
Do not over-water, which reduces oil quality. Provide balanced fertilizer or potassium-rich supplement in summer. Thin fruit if extremely heavy crop to ensure quality.
Harvest & Dormancy (November-March)
4-5 monthsOlives ripen to dark color; tree enters semi-dormant rest period with minimal new growth
Harvest mature olives for oil or table use. Minimal watering needed. Prune lightly after harvest to remove dead wood and shape for next season. Mulch to protect roots in cold regions.

Common Pests
-
Use yellow sticky traps, spinosad sprays, or netting over fruiting branches. Remove fallen fruit promptly.
-
Prune infected branches back to healthy wood. Disinfect tools between cuts. Avoid overhead watering that promotes bacterial spread.
-
Spray horticultural oil during dormant season or early spring. Hand-remove heavily infested branches.
-
Ensure good air circulation. Remove affected leaves. Copper fungicide spray in fall and early spring if severe.
-
Increase humidity with occasional misting. Spray with water to dislodge. Use miticide only if population is very high.

Harvest Tips
Harvest olives when fully dark purple-black for maximum oil content and flavor (November-December in Northern Hemisphere). For table olives, pick at earlier stages (green-yellow) and cure using salt-water or lye methods. Use a harvest cloth beneath branches and gently shake or hand-pick. Process within 24-48 hours for best oil quality.
