Establishment (Year 1)
12 monthsYoung tree develops root system and branch structure; minimal flowering; focus is on vegetative growth
Water regularly during first season; stake for support in windy areas; apply light mulch around base (away from trunk); avoid heavy pruning
Juvenile Growth (Years 2-3)
24 monthsTree grows vigorously, developing framework and canopy; some flowering may occur but fruit set is light
Establish primary scaffold branches through selective pruning; thin crowded branches; maintain consistent watering; begin light annual pruning in late winter
Flowering (Late Winter-Spring, March-May in Northern Hemisphere)
4-6 weeksSmall, inconspicuous white flowers appear in panicles on previous year's growth; flowers are wind-pollinated
Minimal intervention needed; ensure adequate pollination (plant multiple cultivars if possible); avoid excessive nitrogen which promotes vegetative growth over flowering
Fruit Development (Summer-Fall)
4-5 monthsSmall green fruits appear and gradually enlarge; fruits transition from green to purple-black at maturity (typically September-November in Northern Hemisphere)
Thin crowded fruits to 4-6 inches apart if desired for larger olives; provide consistent watering; monitor for pests and diseases; do not over-fertilize
Harvest & Winter Dormancy (Fall-Winter)
3-4 monthsFruits mature to deep purple-black color and are harvested; tree enters dormancy with reduced growth
Harvest for oil when fully ripe (late fall); prune in late winter during dormancy to remove dead wood and shape tree; reduce watering in winter

Common Pests
-
Monitor with pheromone traps; apply spinosad or neem oil when populations detected; harvest fruit promptly to reduce breeding sites
-
Prune affected branches; spray horticultural oil in dormant season; introduce natural predators
-
Remove infected branches and burn; sterilize pruning tools; prune only during dry weather; no chemical cure available
-
Improve air circulation; remove infected fruit and leaves; apply copper fungicide in wet conditions; prune to open canopy

Harvest Tips
Harvest olives when fully ripe (deep purple-black color) in late fall, typically October-November in the Northern Hemisphere. For oil production, pick when fruit is entirely dark; for table olives, harvest earlier when still slightly purple. Hand-pick or use mechanical harvesters, collecting fallen fruit promptly. Coratina olives have high oil content (18-25%) and yield excellent extra virgin oil. Process fruit within 24 hours of harvest for best oil quality.
Fun Facts
- 🌱 Coratina is native to Puglia in southern Italy and is sometimes called 'Coratina della Puglia.' It has been cultivated for centuries and remains one of Italy's most important commercial olive varieties.
- 🌱 Coratina olives are exceptionally high in polyphenols compared to other cultivars—a single drizzle of Coratina oil can contain as much oleocanthal (a natural anti-inflammatory compound) as a dose of ibuprofen, as noted in some Mediterranean nutrition research.
- 🌱 Olive trees are among the longest-living fruit trees; Coratina trees can remain productive for 200+ years, with some ancient specimens in the Mediterranean region documented to be over 1,000 years old.
