Establishment (Year 1-2)
2 yearsYoung tree develops root system and main scaffold branches; minimal flowering expected
Water regularly to establish deep roots; prune to establish open vase or central leader form; mulch lightly; protect from harsh winds
Juvenile (Year 3-4)
2 yearsTree reaches 8-12 feet tall; begins producing scattered flowers and small fruit set
Continue structural pruning; thin competing branches; maintain consistent water during spring; begin light fruit thinning if needed
Flowering (Spring, March-May)
4-6 weeksSmall cream-colored flowers appear in clusters along branches; trees are wind-pollinated
Do not over-fertilize with nitrogen (reduces flowering); ensure good light exposure; hand-pollinate if few pollinators present
Fruit Development (Summer-Fall)
16-20 weeksTiny green fruits develop; gradually enlarge and transition to red, purple, then black as they mature (August-November)
Thin fruit to 1 per 3-4 inches of branch for larger olives; maintain even watering; monitor for olive fruit fly
Harvest & Dormancy (November-February)
12-16 weeksFully black, mature olives ready for harvest; tree enters winter dormancy in colder zones
Harvest by hand or shaking cloth; store olives at 32-50°F if not processing immediately; minimal winter pruning; ensure winter chill requirements met

Harvest Tips
Harvest black, fully mature olives (November-December) for oil production by hand-picking or laying cloth on ground and shaking branches. For table olives, pick at ripe-black stage. Use harvest immediately or refrigerate at 32-50°F for up to 4 weeks. Stagger picking over 2-3 weeks if desired to avoid overwhelming oil mill capacity. Oil yield typically 15-25% by weight of fresh fruit.
