Apricot

Growing Conditions

Growing Zones

Thrives in USDA Zones 5 - 8

Companion Planting

When to Plant

• Transplant

  Bare-root or container trees in early spring while dormant

• Harvest

  Pick when fruit is fully colored, aromatic, and gives slightly to pressure

Organic Growing Tips

• Plant on a slight slope or raised area to reduce late-frost damage to early blossoms.

• Prune for an open canopy with good airflow to reduce brown rot and canker pressure.

• Thin fruit after natural drop so remaining apricots size up and branches are not overloaded.

• Mulch broadly but keep mulch away from the trunk to protect the graft union and crown.

Common Pests

• Brown Rot
• Aphids
• Scale
• Plum Curculio
• Bacterial Canker

Natural History

Apricots originated across the mountains and valleys of Central Asia, with the greatest genetic diversity found in the Tian Shan ranges where wild populations still persist. Chinese cultivation dates back over 4,000 years, with early varieties moving westward along Silk Road trade routes through Persia and Armenia. The species name 'armeniaca' reflects the Roman belief that apricots came from Armenia, though Armenia was a crucial waystation rather than the origin point. Islamic scholars and Persian poets celebrated dried apricots as portable sustenance for desert travel, while fresh apricots became garden treasures in oasis cities. European colonists brought apricot cultivation to California in the 1700s, where Mediterranean-like conditions proved ideal for commercial production. The tree's defining challenge—extraordinarily early spring blooms that risk frost damage—shaped cultivation patterns worldwide, favoring locations with late-spring warming and protected microclimates. This early-blooming nature makes apricots both more difficult to grow reliably than other stone fruits and uniquely valuable where climate conditions align.

Traditional Use

Historical records document apricot fruit, dried apricots, kernels, and kernel oil across Central Asian, Chinese, Persian, and Mediterranean traditional systems, with fruit valued for nutrition during travel and kernels used in various preparations despite toxicity concerns

• Chinese traditional medicine - kernels

  Classical Chinese texts record bitter apricot kernels (xingren) prepared in specific ways, while sweet kernels were used differently, with detailed processing methods to address toxicity

• Central Asian pastoral cultures - dried fruit

  Nomadic peoples relied on dried apricots as concentrated nutrition for long migrations, with drying techniques passed through generations and specific varieties selected for keeping quality

• Persian and Armenian traditions - kernel oil

  Historical accounts describe kernel oil extraction and preparation methods, with Persian physicians documenting both applications and cautions regarding kernel preparations

Apricot kernels contain cyanogenic compounds that release hydrogen cyanide when broken down; bitter kernels contain much higher levels than sweet kernels and historical processing methods addressed this toxicity

Morphology (Plant Structure & Identification)

• Root System

  Deep taproot with extensive lateral root spread; grafted trees develop according to rootstock characteristics with union visible above soil line

• Stem

  Single trunk with spreading, somewhat brittle branches requiring regular pruning for structure and disease prevention; bark smooth when young, developing fissures with age

• Leaves

  Heart-shaped with serrated margins, emerging bronze-green and turning deep green; early leaf drop or yellowing can signal water stress, disease pressure, or natural senescence

• Flowers

  Pink-tinged white blossoms appear before leaves in very early spring, often while frost danger persists; flowers are self-fertile but benefit from cross-pollination for better fruit set

• Fruit

  Orange stone fruits with velvety skin and orange flesh surrounding a large pit; harvest readiness shown by full color development, aromatic fragrance, and slight softening to gentle pressure

Known Varieties

Common cultivars worth knowing

• Moorpark

  Large, flavorful heirloom variety with excellent fresh eating quality but requires long warm season

• Harcot

  Cold-hardy Canadian variety with reliable bloom timing and good disease resistance

  Best for: Northern regions with late spring frosts

• Goldcot

  Self-fertile variety bred for consistent production and cold hardiness

  Best for: Home orchards in zones 5-6

• Chinese/Mormon varieties

  Very cold-hardy selections with later bloom timing, smaller fruit but reliable production

  Best for: Challenging climates with short seasons
