Establishment
1-2 yearsYoung tree developing root system and establishing framework branches; minimal fruiting expected
Water regularly to keep soil consistently moist but not waterlogged. Stake for wind protection. Prune to develop open, goblet-shaped canopy. Avoid heavy fertilizing.
Early Productivity
2-3 yearsTree begins flowering and producing small to moderate fruit crops; canopy filling in
Continue regular watering. Begin light fertilizing with balanced NPK. Remove any crossing or diseased branches. Thin fruit if needed for size.
Flowering & Fruit Set
3-4 months (spring-early summer)Small, cream-colored flowers in spring clusters; fruit develops from fertilized flowers over summer months
Maintain consistent moisture during flower and fruit development. Apply balanced fertilizer in spring. Monitor for pests and disease.
Fruit Development & Maturation
4-5 months (summer-fall)Olives increase in size and gradually change color from green to dark purple-black as they mature over 4-5 months
Water moderately; avoid water stress which affects fruit quality. Reduce nitrogen fertilizing to avoid excessive vegetative growth. Thin crowded fruit if desired for larger size.
Harvest
1-2 monthsMature fruits are dark purple to black; ready for harvest November through January in Northern Hemisphere
Harvest when fully colored for table olives or oil. Use hand-picking or gentle mechanical harvesting. Chill immediately for table olive processing.

Harvest Tips
Barouni olives mature November-January (Northern Hemisphere). Harvest fully ripe (dark purple-black) for table olives or oil production. Hand-pick ripe fruit to avoid bruising, or use gentle mechanical harvesters. For table olives, chill immediately after harvest (32-35°F) to halt ripening and preserve quality. For oil, harvest slightly earlier (dark green-to-purple stage) for better oil content and flavor. A mature tree yields 60-100 lbs of fruit annually under good conditions.
Fun Facts
- 🌱 Barouni is a Tunisian heirloom variety that became famous in the 1990s for producing one of the world's largest table olives, with some fruits weighing up to 8-10 grams
- 🌱 Olive trees are exceptionally long-lived; some specimens over 1,000 years old are still productive, though Barouni trees reach peak production between 20-40 years of age
- 🌱 Barouni trees are largely self-fertile but produce higher yields when cross-pollinated with compatible varieties like Frantoio, Arbequina, or Koroneiki
