Establishment
1-2 yearsYoung tree focuses on root development and branch framework formation. Growth is moderate the first year.
Water regularly (2-3 times weekly in first year), provide stake support, prune to develop open vase shape with 3-4 main scaffold branches. Protect from harsh winds.
Vegetative Growth
2-3 yearsRapid canopy expansion with vigorous branch development. Tree develops characteristic silvery-green foliage.
Continue formative pruning to maintain open canopy for air circulation. Reduce irrigation frequency as tree establishes. Apply balanced fertilizer sparingly in spring.
Flowering
4-6 weeks in springSmall, creamy-white flowers appear in leaf axils in spring (March-May depending on location). Flowers are inconspicuous but fragrant.
Ensure adequate cross-pollination by having compatible pollinizers nearby. Maintain consistent moisture during flowering. Avoid excessive nitrogen which reduces flowering.
Fruit Development
4-5 months (May-September in Northern Hemisphere)Fruits develop from fertilized flowers, growing from green to light pink, then deep purple to black as they mature. Sevillano produces large fruits (6-8 grams each).
Thin fruit if overcropping (remove 50% of fruits on heavy-set branches). Maintain consistent watering during fruit growth. Monitor for pests and diseases.
Harvest & Dormancy
2-3 monthsFruits mature in fall/early winter (September-November). Tree enters dormancy period with minimal growth.
Harvest based on intended use (green table olives in August-September, oil olives in November-December when fully black). Prune in late winter before spring growth begins. Minimal watering during dormancy.

Uses
Table Olives & Curing
CulinarySevillano's large, meaty fruits are excellent for curing as green or black table olives. They develop rich flavor and maintain firm texture through traditional brining or dry-cure methods. [source]
Extra Virgin Olive Oil
CulinaryWhile primarily a table olive, Sevillano can produce quality oil with fruity, grassy notes. Harvest at veraison (color change) for premium oil or wait until fully black for more robust flavor. [source]
Timber & Woodcraft
HouseholdMature olive wood is highly prized for decorative items, cutting boards, and small furnishings due to its beautiful grain patterns and durability. [source]
Leaf Extract & Wellness
MedicinalOlive leaves contain oleuropein and other polyphenols with potential antioxidant and antimicrobial properties. Traditionally used in herbal tea infusions for various wellness purposes. [source]
Pollinator & Bird Support
WildlifeOlive trees attract bees and other pollinators during spring flowering, and birds feed on fruits. The tree provides shelter and food resources in Mediterranean-style landscapes. [source]

Harvest Tips
For table olives (green), harvest in late August to early September when fruits turn from green to light pink; for curing black olives, harvest in November-December when fully black and ripe. Hand-pick or use mechanical harvesters. Fruits should be processed within 24 hours for best quality. Yields typically 100-200 lbs per mature tree.
Fun Facts
- 🌱 Sevillano olives are so large that they're sometimes called 'Queen olives' and can reach the size of a quail egg, weighing up to 8 grams each.
- 🌱 Olive trees are incredibly long-lived; some Sevillano trees in Spain are over 500 years old and still producing fruit, with the oldest known olive tree exceeding 1,000 years.
- 🌱 The silvery appearance of olive leaves comes from tiny hairs that reflect sunlight and reduce water loss—an adaptation to hot, dry Mediterranean climates where these trees originated.
