How to Grow Olive Tree
Olea europaea
The olive tree stands as an evergreen icon in temperate gardens, prized for its drought tolerance and aromatic fruit. Gardeners cultivate these hardy specimens not only for culinary oil but also to add Mediterranean flair to landscapes.

🌾 Sow directly in the garden — Olive Tree is not usually started indoors.
Direct sow seeds outdoors after winter stratification is complete rather than starting indoors before the last frost.
Soil, care & harvest
You cannot sow olive seeds indoors like cool-season crops because they require a long period of cold stratification before germination. Instead, plant seeds outdoors in well-drained soil with a pH between 6.0 and 8.0 during late winter or early spring. Bury the seed about one inch deep; expect germination to take several months once the chill requirement is met.
Space your trees twenty feet apart to allow proper air circulation and canopy development. Once established, these plants need very little water, thriving on low moisture levels typical of their native habitat. Apply a light mulch around the base to retain soil moisture and suppress weeds, but avoid over-fertilizing as they are adapted to poor soils.
Watch for olive fruit fly larvae which can damage developing drupes; use insecticidal soaps or sticky traps to prevent infestation. Harvest ripe olives in late autumn when the skin turns purple-black, picking them by hand or using a pole pruner. The fruit takes roughly 90 days from bloom to maturity under ideal conditions.
