Growing Tips
Olives require 200-400 chill hours (below 7°C) to initiate flowering — insufficient chilling in warm climates causes alternate bearing and poor fruit set.
Prune annually after harvest to open the canopy center — olives fruit on previous year's growth, so remove interior wood that no longer receives light.
Harvest for extra virgin oil when fruits transition from green to purple (veraison) — early harvest yields lower volume but higher polyphenol content and premium prices.
Monitor olive fruit fly (Bactrocera oleae) with yellow sticky traps from July — treat at threshold (5 flies/trap/week) with spinosad bait sprays.
Olives are extremely sensitive to waterlogging — avoid clay soils or install drainage, as Phytophthora and Verticillium thrive in wet root zones.
Alternate bearing is natural in olives — thin fruit in heavy-crop years (remove 30-40% of fruit clusters) to maintain consistent annual production.
