Selecting the Optimal Apricot Varieties

Choosing suitable apricot tree varieties suited to your climate and growing conditions is the critical first step towards success. Carefully consider the following key factors:

Climate Suitability

It’s vital to select cold-hardy varieties if you live in an area with cold winters. Varieties like Harcot, Goldcot, and Moorpark can tolerate temperatures as low as -20°F once established. For hot climates, choose heat-tolerant varieties like Blenheim, Golden Sweet, and Katy.

Chilling Requirements

Most apricot varieties need 600-900 winter chill hours below 45°F to properly set fruit. Check your area’s average chill hours and pick varieties accordingly. Low-chill varieties like Robada, Goldbar, and Sundrop need only 200-400 hours.

Harvest Times

Apricot harvest times range from early season varieties in June to late varieties ripening in August. Stagger planting early, mid, and late season types to enjoy fresh apricots for months.

Pollination Needs

Many apricot varieties are self-fertile while others require a compatible pollinator variety planted nearby. Consult pollination charts to determine your tree’s needs.

Disease Resistance

Choose disease-resistant apricot trees to avoid issues with bacterial canker, brown rot, powdery mildew, and other diseases. Varieties like Goldrich, Harlayne, and Tomcot have strong disease resistance.

Fruit Size and Quality

Consider the flavor, texture, appearance, and productivity of different apricot varieties. On-site taste testing of fruit from mature trees can offer helpful insight.

Preparing the Ideal Soil Environment

Analyzing and amending your existing soil ensures growing conditions tailored to apricot trees. Essential steps include testing pH and nutrient levels, enhancing drainage and structure, and incorporating generous amounts of organic matter. This robust foundation fuels strong root development and lush growth.

Conduct Soil Testing

Lab soil tests measuring pH, nutrients, salinity, and organic matter are invaluable. They reveal existing conditions and any amendments needed for apricots to thrive. For accuracy, collect samples from multiple areas where trees will be planted.

Adjust Soil pH Levels

Apricots grow best in slightly acidic soil with a pH between 6.0-7.0. Add agricultural lime to raise pH in acidic soils or sulfur to lower pH in alkaline soils per test recommendations.

Improve Drainage

Excess moisture can suffocate apricot roots. For heavy clay soil, add organic matter like compost or aged manure to create air pockets. Incorporate coarse sand or small gravel to improve drainage in compacted locations.

Enrich Nutrient Levels

Mix balanced organic fertilizers into the soil a month before planting. Dry organic amendments like alfalfa meal, fish meal, and wood ash provide nitrogen, phosphorus, potassium, and trace elements.

Increase Organic Matter

Incorporate several inches of aged compost, leaf mold, or well-rotted manure when preparing apricot tree beds. This nourishes beneficial microbes and retains moisture during hot, dry periods.

Planting Your Apricot Trees

Once amending the soil, properly planting your apricot trees gives them the strongest start. Careful attention to site selection, digging adequate holes, and providing attentive aftercare ensures vigorous growth.

Choose the Ideal Planting Site

Select a sunny, sheltered spot with well-drained, fertile soil. Avoid frost pockets and areas with poor air circulation. Leave ample space between trees at 15-20 feet apart.

Dig Proper Planting Holes

Dig holes 2-3 times wider than the root ball but no deeper. The root flare should sit 1 inch above grade. Avoid deep planting which suffocates roots.

Settle Trees and Water Thoroughly

Carefully place trees in holes, positioning the graft union 2 inches above soil level. Backfill with native soil, tamp gently to remove air pockets, and water slowly using a hose on low pressure.

Apply Protective Mulch Layer

Surround trees with 2-4 inches of organic mulch like shredded bark or wood chips. Keep mulch 4 inches back from trunks. Refresh mulch in spring.

Providing Attentive Care and Maintenance

Ongoing care through pruning, fertilizing, and monitoring for issues keeps trees healthy and productive for 20-25 years. Implement these best practices:

Employ Strategic Pruning

Prune annually in late winter to shape trees, improve air circulation and sunlight exposure, and control size. Make clean cuts just above buds, pruning suckers and watersprouts first.

Fertilize at Ideal Times

Feed trees 1⁄2 lb 10-10-10 fertilizer per inch of trunk diameter in early spring as growth resumes and again after harvest. Keep fertilizer near feeder roots under the drip line.

Guard Against Pests and Diseases

Promptly treat infestations of borers, aphids, mites, or scale insects organically using horticultural oils or insecticidal soaps. Remove debris and infected plant parts to prevent disease spread.

Harvesting and Enjoying Apricot Bounty

Paying attention to ripeness indicators, using proper picking technique, and understanding storage allows you to enjoy flavorful apricots at their peak.

Monitor Ripeness Telltale Signs

Signs of harvest-ready apricots include vibrant orange color, slightly soft ripe texture, sweet aroma, ease of fruit separation from stems, and tasted sweetness.

Pick Carefully to Avoid Bruising

Harvest early in the day by gently twisting fruit while supporting branches. Use sharp shears for clean separation. Handle apricots carefully to prevent delicate flesh from bruising.

Promptly Store Harvested Fruit

Place picked apricots in a single layer in cool, well-ventilated areas out of the sun. Enjoy fresh, freeze, or can into jams, juices, and sauces.

Overcoming Common Growing Challenges

Arm yourself with solutions for potential issues like frost damage, soil nutrient deficiencies, aggressive wildlife, and harmful insects to keep trees thriving.

Protect Against Frost and Fluctuating Weather

Shield young trees from frost using cloches or fabric covers. Whitewash tree trunks to prevent sunscald and winter freeze-thaw damage. Manage drought stress with mulch and irrigation.

Identify and Correct Nutrient Imbalances

Diagnose nitrogen, iron, zinc, and other deficiencies from soil testing results and leaf analysis. Tailor organic or mineral amendments to restore balance.

Deter Wildlife and Insect Damage

Protect ripening fruit from birds using netting. Apply deer and rodent repellents to discourage browsing. Trap coddling moths and treat other insects as soon as infestations appear.

Implementing an Integrated Pest Management Plan

An integrated pest management (IPM) approach combining cultural, mechanical, and biological controls with targeted applications of least-toxic pesticides when necessary is key to protecting apricot trees from harmful insects and diseases without harming beneficial pollinators.

Cultural Controls

Promote tree health through proper planting, pruning, fertilization, and irrigation to make them less susceptible to pests and diseases. Rake and dispose of fallen leaves and fruit to deny overwintering sites.

Mechanical Controls

Physically remove egg masses, nests, or infested branches. Trap pests like coddling moth larvae or plum curculio beetles on sticky barriers. Handpick pests off leaves and fruit.

Biological Controls

Release or attract beneficial predators like ladybugs, lacewings, trichogramma wasps, and birds. Use Bacillus thuringiensis (Bt) against caterpillars. Apply horticultural oils and insecticidal soaps.

Responsible Pesticide Use

Spot treat with orchard-approved insecticides, fungicides, or herbicides only when monitoring indicates treatment thresholds have been exceeded and cultural controls prove insufficient.

Understanding Chilling Requirements

Apricot trees need exposure to a certain number of chill hours below 45°F during winter dormancy to resume normal growth and bear fruit. Chill hour requirements vary significantly by variety.

Low-Chill Varieties

Best suited to warm winter climates, low-chill apricot varieties like Sundrop, Goldbar, and Autumn Glo only need 200-400 chill hours to set fruit properly.

Mid-Chill Varieties

Moderate-chill varieties adapted to many regions require 400-600 chill hours. Examples include Goldrich, Tilton, and Blenheim apricots.

High-Chill Varieties

In areas with very cold winters, choose high-chill apricot trees needing over 800-900 chill hours like Harogem, Harlayne, or Harglow for best results. Check local chill hours.

Fluctuating Winter Temperatures

If winter warming spikes prevent meeting full chill hour requirements, plant low-medium chill varieties and protect trees from premature bud break using shade cloth covers on warm days.

Mastering Successful Apricot Pollination

Understanding apricot tree pollination dynamics ensures bountiful fruit set. Optimizing cross-pollination and pollinator attraction greatly boosts yields.

Self-Fertile vs Self-Sterile Varieties

While some apricot varieties are self-fertile, many require pollen transfer from a compatible different variety planted nearby. Consult pollination charts before choosing.

Compatible Cross-Pollinator Groups

Group A: Moorpark, Tilton

Group B: Blenheim, Royal

Group C: Goldrich,Perfection

Plant varieties from alternate compatibility groups within 100 feet for effective cross-pollination.

Maximizing Pollinator Visits

Attract native pollinators by providing diverse flowering plants offering pollen and nectar early in spring before apricot trees bloom. Avoid insecticides during bloom time.
