Establishment (Year 1)
12 monthsYoung sapling with tender growth and limited root system
Water regularly (2-3 times weekly), stake for support, avoid heavy pruning, mulch to retain moisture and regulate soil temperature
Juvenile Growth (Years 2-3)
24 monthsTree develops stronger branching structure and deeper root system
Gradually reduce watering frequency, begin light formative pruning to establish open vase shape, apply balanced fertilizer sparingly in spring
Flowering (Spring)
4-6 weeksSmall creamy-white flowers appear in late spring on the previous year's growth
Minimize pruning during this period, maintain consistent soil moisture, avoid excessive nitrogen which promotes vegetative growth over flowers
Fruit Development (Summer-Early Fall)
16-20 weeksFruits mature from green to brown to black over 3-4 months
Thin overcrowded fruit clusters for larger olives, maintain adequate water during dry periods, monitor for pests and diseases
Harvest & Dormancy (Fall-Winter)
8-12 weeksFruits reach peak ripeness (dark color) and tree enters winter dormancy
Harvest mature olives, prune after harvest to maintain shape and next year's productivity, minimize watering during dormancy

Harvest Tips
Harvest olives in fall/winter (September-December in Northern Hemisphere) when fruits turn dark brown to black. For table olives, pick at full ripeness for softer texture and milder flavor. For oil production, harvest slightly earlier for peppery flavor or fully ripe for buttery profile. Use hand-harvesting or place tarps under trees and gently vibrate branches. Olives must be cured or processed to remove bitter compounds before consumption.
Fun Facts
- 🌱 Manzanillo means 'little apple' in Spanish, referring to the fruit's round shape and size relative to other olive varieties.
- 🌱 Olive trees can live 300+ years and become increasingly productive with age; some Mediterranean trees are over 1,000 years old.
- 🌱 Manzanillo is self-fertile but produces better crops with cross-pollination from compatible varieties like Arbequina or Frantoio.
