Dormancy
November-MarchBare branches in winter; tree is leafless and appears dormant
Minimal watering; prune during late dormancy (February-March). Remove dead, diseased, or crossing branches. Thin branches to open up canopy for light penetration.
Bud Break & Flowering
March-AprilPink-white blossoms emerge before leaves; flowers are delicate and fragrant
Protect from late frosts with frost cloth if temperatures drop below 32°F. Do not fertilize heavily as this can reduce flowering. Ensure good pollination—Blenheim is partially self-fertile but benefits from cross-pollination with other apricot varieties.
Leaf & Shoot Growth
April-MayLeaves emerge and canopy fills out; tree grows vigorously with long shoots
Apply balanced fertilizer in early spring. Maintain consistent watering. Thin crowded shoots to improve air circulation. Watch for early pest and disease pressure.
Fruit Development & Ripening
May-JulySmall green fruits develop and gradually enlarge, turning golden-orange as they mature
Thin fruit when marble-sized to 4-6 inches apart for larger, higher-quality fruit. Apply mulch to conserve moisture and regulate soil temperature. Provide support for heavy fruit loads.
Harvest
June-JulyFruit reaches full golden-orange color, becoming fragrant and yielding slightly to gentle pressure
Harvest when fruit comes away easily from branch. Pick regularly to encourage continued ripening. Handle gently to avoid bruising.

Harvest Tips
Blenheim apricots ripen from late June to early July depending on location. Harvest when fully colored and fragrant, yielding slightly to gentle pressure. For fresh eating, allow to fully ripen on the tree for maximum sweetness. For preserving, pick slightly firmer fruit. A mature tree can produce 50-100 pounds of fruit annually.
Fun Facts
- 🌱 Blenheim is also known as 'Moorpark' in some regions, though technically they are distinct cultivars—Blenheim is a California-selected clone renowned for superior flavor and reliability.
- 🌱 The apricot kernel inside the pit contains amygdalin, which can convert to cyanide if consumed in large quantities; remove and discard kernels before eating or processing fruit.
- 🌱 Blenheim apricots were originally cultivated in Central Asia and arrived in California via the Silk Road trade routes, becoming the backbone of the California dried apricot industry.
