Establishment
2-3 yearsYoung sapling with small canopy establishing root system
Water regularly for first 2-3 years. Stake if needed in windy locations. Apply mulch 3-4 inches from trunk. Prune to develop strong central leader.
Vegetative Growth
3-5 yearsTree develops mature form with dense canopy of silvery-green leaves
Continue regular watering during growing season. Prune to open canopy for light penetration. Apply balanced fertilizer in spring.
Flowering
4-6 weeks (April-May in Northern Hemisphere)Small cream-colored flowers appear in late spring along branches
Ensure adequate chilling hours (200-300 hours below 45°F) were received for flower set. Avoid excessive nitrogen fertilizer which promotes foliage over flowers. Allow trees to experience natural cold exposure.
Fruit Development
5-6 monthsSmall green fruits form and grow throughout summer, transitioning to dark purple-black by fall
Thin fruits if overly dense to promote larger olives. Water consistently during this period. Monitor for pest/disease issues.
Harvest & Dormancy
2-3 monthsFruits reach full dark color and mature flavor by fall/early winter. Tree enters dormancy with minimal leaf activity.
Harvest ripe olives from September through November. Prune after harvest to maintain shape and encourage next year's flowering. Minimal watering needed during dormancy.

Harvest Tips
Kalamata olives are harvested when fully ripe and dark purple-black (late September through November). Harvest by hand-picking or using mechanical harvesters, collecting fruit in nets. Olives are ready for curing when they yield slightly to pressure. For table olives, harvest by shaking branches and catching in tarps. Process soon after harvest for best flavor.
