Establishment (Year 1-2)
1-2 yearsYoung tree focuses on root development and establishing a strong framework. Canopy is sparse and growth is moderate.
Water regularly to establish roots; apply 2-3 inch mulch layer; prune to develop central leader or open vase structure; protect from hard freezes in cold zones.
Growth & Structure (Year 2-3)
1-2 yearsTree develops fuller canopy and stronger branch structure. Foliage becomes dense and silvery-green.
Continue formative pruning; maintain consistent watering; begin fertilizing lightly in spring; watch for early pests.
Pre-Flowering (Year 3-4)
1-2 yearsTree reaches mature form with well-established canopy. First small flower clusters may appear.
Reduce pruning to minimal maintenance; apply balanced fertilizer in spring; ensure good air circulation; thin excessive growth.
Flowering & Fruit Development (Spring-Summer)
4-5 monthsTiny cream-colored flowers appear in spring clusters; if pollinated, small green fruits develop and enlarge throughout summer.
Plant compatible pollinators nearby for better set (self-fertile but benefits from cross-pollination); provide consistent deep watering; avoid heavy nitrogen fertilizing which reduces flowering.
Harvest (Fall-Winter)
6-8 weeks harvesting periodGreen olives reach full size (pencil-thin, 1.5-2 inches long) in early fall; can be harvested at this stage or allowed to darken to dark green/black for cured olives.
Hand-harvest or use mechanical shaker; wear gloves to protect from oil and branch pricks; cure fresh-picked olives within 24 hours for best flavor.

Harvest Tips
Picholine olives destined for fresh eating are harvested when fully mature green (September-November), firm yet slightly yielding to pressure. Hand-pick to avoid bruising; use a ladder carefully as branches are sometimes brittle. For curing, harvest olives and process within 24 hours using lye brine or dry salt methods. Yields typically 10-20 pounds of fresh olives per mature tree annually. Peak production occurs after tree is 6-8 years old.
Fun Facts
- 🌱 The Picholine cultivar originated in the Languedoc region of southern France in the 17th century and was named after a French producer, though its exact etymology remains debated among olive historians.
- 🌱 Picholine olives are naturally green when ripe, unlike most olive varieties that darken to black; this unique trait made them historically identifiable and tradeable in Mediterranean markets.
- 🌱 A mature Picholine olive tree can live 300+ years and remain productive throughout its lifespan, with some ancient trees in the Mediterranean still bearing fruit after 500 years.
