Growing Olive Trees

Choosing the Right Variety
- Arbequina: Small, hardy tree that produces small, flavorful olives. Suitable for warm climates.
- Koroneiki: High-yielding tree that produces small olives with a high oil content.
- Mission: Large, slow-growing tree that produces large, meaty olives.

Planting
- Location: Choose a sunny spot with well-draining soil. Olive trees need at least 6-8 hours of sunlight daily¹.
- Soil: Prefer well-drained soil with a pH between 5.5 and 7.5¹.
- Planting Time: Plant in early spring or fall when temperatures are mild².
- Spacing: Space trees about 20 feet apart to allow for growth and air circulation².
Watering Olive Trees
- Young Trees: Water deeply once a week during the first two years to establish strong roots³.
- Mature Trees: Olive trees are drought-tolerant but benefit from deep watering every two weeks during dry periods³.
- Avoid Overwatering: Ensure the soil is well-drained to prevent root rot³.
Harvesting Olives
- Timing: Olives are usually ready for harvest in late fall to early winter⁴.
- Indicators: Ripe olives change color from green to black or purple, depending on the variety⁴.

- Brine Curing: Soak olives in a saltwater solution for several weeks, changing the brine periodically.
- Dry Curing: Pack olives in salt for several weeks, then rinse and store in olive oil.
- Lye Curing: Use a lye solution to cure olives quickly, then rinse thoroughly and soak in brine.
Maintaining Olive Trees

Pruning
- Timing: Prune in late winter or early spring before new growth begins³.
- Method: Remove dead or diseased branches, thin out crowded areas, and shape the tree to improve airflow and sunlight penetration³.
-
Fertilizing
- Type: Use a balanced fertilizer or compost to provide essential nutrients³.
- Frequency: Fertilize in early spring and again in late summer³.

Pest and Disease Management
