Overview of the Apricot Tree (Prunus armeniaca)
The apricot tree, Prunus armeniaca, is one of the most rewarding fruit trees you can grow in a home garden. Despite its name suggesting Armenian origins, modern research points to China as its true birthplace — it has been cultivated for over 4,000 years! Today, apricot trees are grown across temperate regions worldwide, prized equally for their fragrant spring flowers and their golden fruits.
Among the many cultivars available, the Moorpark apricot stands out as a classic favorite. It produces large, richly flavored fruits with a beautiful blush-orange skin — a variety that has remained popular with home growers and commercial orchards alike. Other well-known cultivars include Stark and Zaiglo, but Moorpark remains the benchmark for flavor and reliable harvests.
Beyond their delicious fruits, apricot trees offer real economic value. Apricots rank among the top commercially traded stone fruits globally, and their nutritional profile — rich in vitamin A, potassium, and dietary fiber — makes them a true superfood straight from your backyard.

Growing Conditions for Apricot Trees
Ideal Soil Types
Apricot trees thrive in well-drained, loamy soil with a pH between 6.0 and 7.0. They are particularly sensitive to waterlogged conditions — poor drainage is one of the most common reasons apricot trees struggle or fail. Sandy loam soils work beautifully, while heavy clay soils should be amended with organic matter before planting.
If you're planting in a clay-heavy garden, consider raising the planting area slightly or building a mound to improve drainage. A healthy root system depends entirely on soil that breathes well and never stays soggy for long.
Sunlight Requirements
Apricot trees are sun-lovers — full day sunlight (at least 6 to 8 hours) is non-negotiable for good fruit production. Less sunlight means fewer flowers in spring and smaller harvests come summer. Position your tree in the sunniest spot in your garden, away from large structures that cast shade.
According to Utah State University Extension, full sun exposure also helps keep the tree's canopy dry, which reduces the risk of fungal diseases — a win-win for both growth rate and fruit quality.
A Moorpark apricot tree planted in full sun and well-drained soil can grow 8 to 15 inches per year once established. Trees grown in partial shade or compacted soil may grow less than half that rate.
Growth Rate of Apricot Trees
Factors Affecting Growth Rate
Several variables influence how fast your apricot tree will grow. Soil quality, sunlight, water availability, fertilizer use, and the rootstock the tree is grafted onto all play a role. Standard rootstocks tend to produce larger, slower-maturing trees, while dwarfing rootstocks speed up fruiting but keep overall size more manageable.
Climate matters enormously too. Apricot trees need a certain number of chill hours (typically 700–1,000 hours below 45°F) during winter to break dormancy properly and produce flowers in spring. Without adequate winter cold, growth and fruiting will both suffer.
Average Growth Rates and Varieties
Under good conditions, Moorpark apricot trees are considered moderate to fast growers, adding roughly 1 to 2 feet of height per year. Stark and Zaiglo cultivars follow similar growth patterns, though dwarf varieties naturally stay more compact. Within 3 to 5 years of planting, most trees begin producing fruit — the wait is absolutely worth it!

Size Parameters of Mature Apricot Trees
Mature Height and Width
A standard Moorpark apricot tree typically reaches a mature height of 15 to 20 feet, with a spread of similar width. Dwarf varieties stay closer to 8 to 10 feet tall — ideal for smaller gardens or even large containers. Knowing this before planting helps you space trees properly: standard trees need at least 20 feet between them.
Tree Structure, Branches, and Pruning for Size Control
Young apricot trees produce upright, fast-growing branches that need early training. As the tree matures, the branch structure spreads outward, creating a rounded, open canopy. This natural form is actually great for fruit production — sunlight can reach interior branches more easily.
Pruning is your best tool for keeping size under control. Annual pruning in late winter or early spring (before new growth begins) encourages strong branch development and prevents the tree from becoming too dense. Remove crossing branches and any growth heading toward the center of the canopy to maintain good airflow.
Planting and Establishment
Best Practices for Planting
The best time to plant apricot trees is in early spring, once the ground is workable but before the tree breaks dormancy. Bare-root trees planted in early spring establish quickly and often outperform container-grown trees planted later in the season. Dig a hole twice as wide as the root system, but no deeper than the roots naturally sit.
Eliminating Air Pockets and Ensuring Proper Planting
Once you've positioned the tree, backfill with your native soil — no need to amend heavily unless drainage is truly poor. Water thoroughly as you fill to eliminate air pockets around the roots. Proper planting depth is critical: the graft union should sit about 2 inches above the soil surface to prevent rootstock suckering.
- Choose a site with full day sunlight and well-drained soil
- Plant bare-root trees in early spring for the best establishment
- Water deeply after planting to settle soil around roots
- Mulch around the base to retain moisture, keeping mulch away from the trunk
Pruning, Maintenance, and Common Problems
Spring Pruning and Borer Prevention
Spring pruning does more than control size — it actively protects your tree. Peach tree borers are one of the most common pests affecting apricot trees, and they tend to target stressed or wounded wood. By removing dead and damaged branches cleanly each spring, you reduce entry points for these destructive insects.
Apply a balanced fertilizer in early spring as buds begin to swell. Avoid over-fertilizing with nitrogen, which pushes leafy growth at the expense of fruit. A soil test from your local university extension service is a smart investment before applying any fertilizer.
Pest Management and Soil Issues
Beyond borers, apricot trees can be affected by aphids, brown rot fungus, and bacterial canker. Good airflow through proper pruning and full sunlight are your first line of defense. Signs of poor drainage — yellowing leaves, stunted growth, root rot — should be addressed immediately by improving the root zone environment.

Harvesting and Where to Buy Moorpark Apricot Trees
When to Harvest
Apricots are ready to harvest when the fruit gives slightly to gentle pressure and has developed its full golden-orange color — usually from late June through July, depending on your climate. Unlike many fruits, apricots do not ripen well off the tree, so timing your harvest correctly produces the best flavor.
Pricing and Where to Buy
Young Moorpark apricot trees are widely available from reputable nurseries, online plant retailers, and organizations like the Arbor Day Foundation. Shipping is typically available for bare-root trees in late winter and early spring. Prices for young trees generally range from $25 to $60, while more mature, container-grown specimens can command a higher price — sometimes $80 to $150 or more depending on size and cultivar.
When comparing cultivars like Moorpark vs. Stark vs. Zaiglo, consider your local chill hours. Moorpark performs best with 700–900 chill hours, while some newer cultivars like Zaiglo are bred for lower-chill climates. Check with your local extension office before purchasing.
Frequently Asked Questions
How fast does a Moorpark apricot tree grow?
Under good growing conditions with full sunlight and well-drained soil, Moorpark apricot trees grow roughly 1 to 2 feet per year. Proper care — adequate water, annual pruning, and appropriate fertilizer — helps maintain this healthy growth rate.
When is the best time to plant an apricot tree?
Early spring is ideal, particularly for bare-root trees. Planting while the tree is still dormant gives roots time to establish before the demands of summer heat and fruit production begin.
How tall will my apricot tree grow?
A standard Moorpark apricot tree will reach 15 to 20 feet tall and wide at maturity. Dwarf and semi-dwarf cultivars stay considerably smaller, making them a great choice for compact gardens or when you want fruit within easy reach for harvesting.
