Growing, Harvesting and Storage

Olea europaea grows best in well-drained, loamy soils with a slightly acidic to neutral pH, thriving in full sun to partial shade and requiring moderate water during its growing season. It is a resilient plant that benefits from regular pruning to maintain its shape and promote healthy growth, along with periodic fertilization to support fruit development. The olive fruit is typically harvested in late summer to early autumn when it turns from green to black, using gentle shaking or hand-picking to avoid damaging the branches. After harvesting, the fruit should be dried thoroughly in a cool, shaded area to preserve its potency, and stored in airtight containers in a cool, dark place or refrigerated to extend shelf life. Proper storage is essential to maintain the medicinal properties of the plant, ensuring its efficacy for use in traditional remedies and modern applications.
