Apricot Tree Growing Guide
The short answer: Apricots (Prunus armeniaca) grow best in USDA Zones 5–8, with hardy cultivars pushing into Zone 4 and low-chill types extending into Zone 9. The tree’s one real constraint is its early bloom — often late February or March — which puts flowers at risk of late frost, so choosing a late-blooming cultivar and siting for cold-air drainage matter more than for any other stone fruit.
1. Introduction
Apricots reward patience with the best fresh-eating stone fruit there is, but they bloom earlier than any other temperate fruit tree, so the grower’s job is matching cultivar to climate and siting to dodge late frost.
Apricots (Prunus armeniaca) are the stone fruit with both the highest reward and the greatest gamble. A fully ripe tree-grown apricot is incomparable — sweet, fragrant, juicy — and bears no resemblance to the firm, mealy supermarket version. The catch: apricots bloom earlier than any other temperate fruit tree, often in late February or early March, which puts the flowers directly in the path of late freezes. Many growers in Zones 5–7 get a full crop only 3 out of 5 years.
This is also a tree that, when sited well, produces 100+ pounds of fruit by year 8 and lives 30+ years with little intervention. Apricots are largely self-fertile, surprisingly drought-tolerant once established, and far less disease-prone than peach or plum. The key to success is choosing the right cultivar for your climate and siting the tree to delay bloom past the last typical frost.
This guide covers apricot growing across USDA Zones 4–9. Late-blooming cultivars (Harglow, Goldrich, Moorpark) push the range north and reduce frost loss; low-chill cultivars (Katy, Royal Rosa) extend the range south. The two non-negotiable considerations are matching cultivar to chill hours and bloom timing and siting to avoid frost pockets.
Quick Facts Table
Aspect | Details |
|---|---|
| USDA Hardiness Zones | 5–8 reliable; Zone 4 with hardy cultivars (Harglow, Moorpark); Zone 9 with low-chill cultivars |
| Mature Height | Standard: 15–20 ft; Semi-dwarf: 12–15 ft; Dwarf: 8–10 ft |
| Mature Spread | Standard: 15–20 ft; Semi-dwarf: 12–15 ft |
| Time to First Harvest | 3–5 years (semi-dwarf); 4–6 years (standard) |
| Chill Hours Needed | 300–500 (low-chill cultivars) to 700–900 (most standard cultivars) |
| Soil pH | 6.0–7.5 (slightly acidic to slightly alkaline); tolerates 5.5–8.0 |
| Lifespan | 20–30 years (commercial); up to 40 years with care |
| Pollination | Most cultivars self-fertile; yield improves 10–20% with cross-pollination from a second variety |
Key Takeaway: Pick a late-blooming cultivar matched to your chill hours, site it where cold air drains (slope, raised site) rather than pools, and accept that some years the crop is lost to late frost. In good years, the harvest is unmatched.
2. Choosing the Right Variety
Match a cultivar’s chill-hour requirement to your winter and favor later-blooming types in frost-prone zones — this single choice matters more for apricots than for any other fruit tree.
Apricot cultivar selection is more important than for any other temperate fruit tree, because the wrong variety means consistent crop failure rather than a smaller harvest. Two factors dominate the choice: bloom timing (late-blooming reduces frost loss) and chill hour requirement (must match your local winter).
Late vs Early Blooming — The Frost Equation
Apricots bloom 1–3 weeks earlier than peaches in the same location. In Zones 5–7, that timing routinely puts open flowers in the path of late frosts. Cultivars are graded by their relative bloom time, and the difference between ‘very early’ and ‘late’ can be 7–10 days — enough to dodge most late freezes in a typical year.
Chill Hour Requirements
- High-Chill (700–900 hours): Moorpark, Harglow, Goldrich, Goldcot — Zones 5–7 with reliable winter cold.
- Mid-Chill (500–700 hours): Tilton, Blenheim, Perfection — Zones 6–8, the broadest-adapted group.
- Low-Chill (300–500 hours): Katy, Gold Kist, Royal Rosa — Zones 8–9 and coastal California where winters are mild.
Variety Comparison Table
Cultivar | Bloom Timing | Zones | Chill Hours | Best Use / Notes | Self-Fertile? |

Recommended Plantings by Climate
- Frost-prone Zone 5–6: Harglow (late bloom) + Goldcot (hardy, mid-late). Pair extends harvest 2–3 weeks.
- Pacific Northwest: Goldrich + Moorpark — both late-blooming, both proven in the regional climate.
- Great Lakes / Upper Midwest: Goldcot + Harglow. Manchurian apricot for Zone 3–4 edges.
- California / Low-Chill South: Blenheim (the flavor benchmark) + Katy (for early harvest).
- Mid-Atlantic / Southeast: Tilton + Moorpark.
Harvest Windows
Most apricots ripen in July, with regional variation extending the window from late June (Zone 9) to early August (Zone 5).
- Early Season (late June–early July): Katy, Royal Rosa, Blenheim.
- Mid Season (mid–late July): Tilton, Perfection, Goldcot.
- Late Season (late July–early August): Moorpark, Harglow, Goldrich.
3. Site Selection & Preparation
Full sun, well-drained soil, and a site where cold air drains away rather than pools are the three non-negotiables; a low spot in the yard will cost you the bloom most years.
Apricot site selection is more demanding than other stone fruits because of the late-frost risk. The right site has full sun, excellent drainage, AND elevation above the local cold-air pool. The wrong site (low spot in the yard, north-facing valley) will produce frost-killed flowers every year.
Sunlight Requirements
Full sun — at least 8 hours of direct daily light from spring through fall. Apricots in partial shade ripen unevenly, produce less, and are more disease-prone.
Soil and pH
Apricots tolerate pH 6.0–7.5 and a wider range than most stone fruits. Deep, well-drained loam is ideal. Sandy loam is excellent; clay works if drainage is adequate. Apricots are prone to iron chlorosis (yellow leaves with green veins) on heavily alkaline soils.
Drainage — Critical
Apricots have little tolerance for wet or compacted soil. Phytophthora root rot and crown rot are leading killers on poorly drained sites. An 18-inch test hole should drain within 8 hours. Avoid sites with seasonal standing water.
The Frost-Pocket Problem — The Biggest Apricot Decision
This is the single most important apricot siting consideration. Because apricots bloom 1–3 weeks before peaches, in many Zone 5–7 yards the flowers open just as the last typical frost arrives. Site to maximize cold-air drainage and minimize cold-air pooling:
- Plant uphill on a gentle slope. Cold air flows downhill; a tree on a slope above a low spot stays 3–5°F warmer on still spring nights.
- Avoid low spots in the yard, valley bottoms, and depressions where frost pools.
- North-facing aspects delay bloom 7–10 days, which often dodges the late frost in a typical year.
- South-facing walls or large boulders radiate heat at night and protect blooms from short freezes.
- Frost-protected microclimates (near a pond, between buildings) are classic apricot sites.
Wind Protection
Apricots are vulnerable to wind damage during bloom (knocks off flowers) and during fruit development (bruises and drops fruit). A wind-protected site — building eave, hedgerow, sheltered orchard — produces healthier trees and higher yields.
Spacing Guidelines
Tree Type | In-Row × Between-Row |
|---|---|
| Standard apricot | 18–22 ft × 22 ft |
| Semi-dwarf apricot | 12–15 ft × 18 ft |
| Dwarf apricot (Pixie rootstock) | 8–10 ft × 12 ft |
| Espalier on a wall | 8–10 ft between trees |
| Permaculture row | 20 ft minimum between trunks |
4. Planting Instructions
Plant bare-root or container stock in late winter to early spring with the graft union 2–4 inches above grade, mounding on heavier soils to keep the crown dry.
Apricots establish reliably from both bare-root and container stock when planted in late winter or very early spring. Most apricots are grafted onto peach, plum, or apricot rootstock — keep the graft union above grade. Plant on a slight mound on heavier soils to improve drainage at the crown.
When to Plant
- Bare-root: Late winter through early spring while dormant. Zones 4–5 target April; Zones 6–7 March; Zones 8–9 January–February or November.
- Container-grown: Spring through early summer in cold climates.
- Best month overall: Late February through March for most US growers.
The Planting Hole
Dig a hole twice as wide as the root ball, same depth. Backfill with native soil; do not amend with compost or fertilizer in the hole.
Planting Depth — Graft Above Grade
Set the graft union 2–4 inches above the surrounding soil grade. On heavier soils, build a small mound (8–12 inches tall, 4–5 feet wide) and plant on top of it to improve crown drainage and reduce Phytophthora risk.
Initial Watering and Mulch
Water deeply (5–10 gallons) at planting. Apply 3–4 inches of wood-chip mulch in a 3-foot ring, kept 3 inches back from the trunk to prevent crown rot — apricots are especially susceptible.
Year-One Establishment
Water deeply twice a week through the first growing season unless rainfall is reliable. Remove any flowers in year one to redirect energy to roots and structural growth. Expect 1–3 feet of new growth in year one — modest while the root system establishes.
5. Pollination and Fruit Set
Nearly every named apricot cultivar is self-fertile, so one tree makes a full crop; a second variety with overlapping bloom adds 10–20% more yield but isn’t required.
Apricot pollination is one of the simpler stories in stone fruit. Most named cultivars are self-fertile and will produce a full crop on a single tree. Cross-pollination from a second compatible cultivar bumps yield 10–20%, but unlike Japanese plums, a solo apricot is a viable choice.
- Self-fertile cultivars (the standard): Moorpark, Tilton, Blenheim, Goldcot, Harglow, Goldrich, Perfection, Katy, Royal Rosa, Manchurian — all self-fertile.
- For best yield: Plant two cultivars with overlapping bloom (e.g., Harglow + Goldcot in cold zones; Moorpark + Tilton in moderate zones; Blenheim + Katy in low-chill regions).
- Bloom-time matching: Same bloom group (early/mid/late) matters more than species — pair late-late or mid-mid for best cross-pollination.
Apricot flowers are pollinated by honeybees and native bumblebees. The early bloom timing means cold rainy weather can prevent pollinator flight — a major risk in Zones 4–6 in some years. Pollinator habitat (undisturbed margins, hedgerow plantings) supports apricot pollination but cannot fully compensate for cold-weather flight bans.
6. Pruning and Training
Train to an open-vase form like a peach, then prune annually in late summer after harvest — not in winter — removing about 20–30% of the prior year’s growth and thin fruit to one per 3–4 inches of wood by early June.
Apricots are pruned similarly to peaches — to an open-vase form that admits light to the entire canopy and supports the heavy crop that mature trees carry. The wood is brittle and overloaded branches will split, making annual maintenance pruning critical for tree longevity.
Training a Young Tree (Years 1–4)
Open-vase form, like peaches:
- Year 1: At planting, head the unbranched whip back to 24–30 inches. Select 3–4 future scaffold branches at 18–24 inches off the ground, spiraling around the trunk and angled outward at 45–60 degrees.
- Year 2: Remove the central leader entirely. Select the 3–4 strongest scaffolds; remove competitors. Head scaffolds back to outward-facing buds 18 inches from the trunk.
- Years 3–4: Develop secondary scaffolds off the main scaffolds. Keep the canopy center open — admit light to interior fruiting wood.
Maintenance Pruning (Years 5+)
Once a year in late summer, after harvest and while the weather is dry, remove:
- Dead, damaged, broken, and crossing branches.
- Bacterial canker-infected wood (cut 6 inches below the canker; burn the debris).
- Inward-growing branches crowding the canopy center.
- Watersprouts.
- Branches drooping to within 18 inches of the ground.
- About 20–30% of the prior year’s growth each year — apricots fruit on 1-year-old wood, so renewal pruning matters.
Fruit Thinning
Apricots set 3–5× more fruit than the tree can size up. Thin to one fruit per 3–4 inches of fruiting wood by early June (when fruit is marble-sized). Unthinned apricots produce small fruit, break branches under load, and exhaust the tree into biennial bearing.
Summer Pruning
Make structural cuts in late summer, once the fruit is off and the weather is dry. Apricots are prone to Eutypa dieback and bacterial canker, and both infect fresh pruning wounds in cool, wet conditions — so a cut that heals cleanly in August can turn into a canker if you make it in February. Finish at least four to six weeks before the fall rains arrive, giving the wounds time to seal.
Pruning Calendar
Month | Task |
|---|---|
| January–February | Dormant — inspect structure only. Avoid cuts; wet-season wounds invite Eutypa and bacterial canker. |
| Late February–March | Dormant to pre-bloom — inspect only. Avoid cuts. |
| March–April | Bloom — hands-off. Frost watch. |
| Late May–early June | Fruit thinning to one per 3–4 inches. |
| June–July | Light removal of broken or diseased wood. Cut bacterial canker promptly. |
| Late July–August | Harvest, then the main structural pruning window opens once fruit is off and the weather is dry. |
| September–October | Finish structural cuts at least 4–6 weeks before fall rains so wounds can seal. |
| November–December | No pruning. Assess canopy structure and plan next summer’s cuts. |
7. Ongoing Care & Maintenance
Apricots need modest fertility and steady moisture during fruit fill, but the biggest ongoing job is sanitation — brown rot and bacterial canker respond to cleanup more than to spraying.
Apricots respond to consistent moisture, modest fertility, and meticulous sanitation. The two killers — brown rot and bacterial canker — both respond more to sanitation than to spray schedules. Most ongoing care is just paying attention.
Water Management
Stage | Approach |
|---|---|
| Year 1 establishment | 5–10 gallons twice weekly unless rainfall is reliable. |
| Years 2–3 | Deep weekly watering during dry spells. 10–15 gallons per watering. |
| Years 4+ established | Biweekly during summer dry weather; established apricots are notably drought-tolerant. |
| Fruit fill (June–July) | Consistent moisture is critical for fruit size. Drought now causes premature drop and split-pit defects. |
| Post-harvest (August) | Reduce water to slow new growth and encourage hardening. |
| Late fall watering | Deep watering before winter freeze (Zones 4–6) prevents winter desiccation. |
Fertilization
Modest needs. Most established apricots need only a single light spring fertilization. Over-fertilizing — especially with high nitrogen — pushes soft growth highly susceptible to bacterial canker and brown rot, and reduces winter hardiness.
- Year 1: No fertilizer.
- Year 2+: 1 lb 10-10-10 per inch of trunk diameter, broadcast under the dripline in early spring.
- Organic equivalent: 2–3 inches of compost top-dressed each spring; supplemental kelp meal if leaves are pale.
- Alkaline soils: Chelated iron supplementation may be needed to prevent chlorosis (yellow leaves with green veins).
Mulch Renewal
Refresh wood-chip mulch annually. Maintain 3–4 inches of depth; keep mulch 3 inches back from the trunk.
Frost Protection
In Zones 5–7, an apricot in bloom may need active protection from late frosts. Options range from simple (cover with a sheet on still cold nights — 3–5°F of protection) to elaborate (overhead sprinklers create a protective ice layer — 5–8°F of protection if applied continuously during the freeze, but requires significant water and infrastructure). For most home growers, a light sheet on forecast frost nights is enough to save a marginal year’s crop.
8. Pest and Disease Management (Organic)
Bacterial canker, brown rot, and Coryneum blight (shothole) cause the most damage; sanitation, airflow pruning, and well-timed copper sprays are the organic foundation for all three.
Apricots share most of the disease pressure of peaches and plums plus some species-specific issues. Bacterial canker, brown rot, and Coryneum blight (shothole) are the big three. Sanitation, airflow pruning, copper sprays at key timing, and well-sited stress-free trees are the foundation of organic management.
Major Diseases
Disease | Identification & Management |
|---|---|
| Brown Rot (Monilinia fructicola) | Tan to brown spots on ripening fruit; mummies overwinter. Manage: remove ALL mummies; thin fruit for airflow; harvest at first ripeness; sulfur or Bacillus subtilis spray at petal fall and again 3 weeks pre-harvest. |
| Bacterial Canker (Pseudomonas syringae) | Dark sunken cankers on trunk and branches, often weeping amber gum. The leading killer of young apricots. Manage: avoid pruning in wet weather (entry point); copper spray at leaf drop and bud swell; remove infected wood 6 inches below canker; reduce tree stress; choose resistant rootstock. |
| Coryneum Blight / Shothole (Wilsonomyces carpophilus) | Small purple spots on leaves that dry and fall out — leaving ‘shothole’ appearance. Can defoliate young trees. Manage: copper spray at leaf drop and again at bud swell; sanitation of fallen leaves. |
| Cytospora Canker (Leucostoma persoonii) | Cankers on branches and trunk, often around pruning wounds. Manage: prune during dry weather; keep trees vigorous; remove cankered wood promptly. |
| Phytophthora Root and Crown Rot | Wilt despite moist soil; bark sloughs at the crown. Manage: drainage is the only cure. Plant on mounded sites in heavy soil. |
Major Pests
Pest | Identification & Management |
|---|---|
| Peach Tree Borer | Larvae bore into trunk at soil line; gum and frass at base. Manage: paint trunks white to prevent egg-laying; pheromone traps to time interventions; nematode soil drench (Steinernema carpocapsae) for severe pressure. |
| Plum Curculio | Weevil that lays eggs in young fruit; crescent-shaped scars. Manage: tarp-shake at first fruit set; kaolin clay (Surround) at petal fall and weekly through June; spinosad as last resort. |
| Aphids | Cluster on new growth; curl leaves; honeydew. Manage: water blast; encourage lacewings and ladybeetles; insecticidal soap. |
| Spider Mites | Hot dry summer pest. Fine webbing under leaves; stippled leaf damage. Manage: high-pressure water spray on leaf undersides; encourage predatory mites; insecticidal soap or sulfur as last resort. |
| San Jose Scale | Small immobile bumps on bark; sap-sucking damage. Manage: dormant horticultural oil; predatory ladybeetles. |
| Birds, Squirrels, Raccoons | All take ripening fruit. Manage: bird netting on smaller trees; harvest aggressively as fruit colors. |
9. Harvest and Storage
Pick when the fruit is fully orange and yields to gentle thumb pressure, walking the tree every 1–2 days during peak ripening since apricots color unevenly and bruise easily.
Apricots reach their peak quality when fully tree-ripened — a stage rarely seen in commerce because tree-ripe apricots ship poorly. The difference between a hard pinkish supermarket apricot and a fully ripe orange-fleshed home-grown one is enormous. Harvest is the payoff for the year of planning and frost-dodging.
Ripeness Cues
A ripe apricot is fully orange (no green or yellow tones), fragrant when sniffed at the stem end, and yields slightly to gentle thumb pressure. The fruit detaches from the spur with a slight twist. If you have to pull hard, it is not ready.
Harvest Frequency
Apricots ripen unevenly across the tree over 1–2 weeks. Walk the tree every 1–2 days during peak ripening, picking only the ripest fruit each visit. Apricots left past peak drop quickly and attract wasps.
Picking Technique
- Twist gently; ripe apricots release with a slight twist.
- Pick into shallow padded containers (4 inches max depth). Apricots bruise extremely easily.
- Morning harvest gives the longest shelf life.
- Avoid washing fruit until just before use.
Storage Methods
Method | Approach & Shelf Life |
|---|---|
| Refrigeration (firm-ripe) | 32–34°F. 1–2 weeks for firm-ripe fruit. Fully ripe apricots: 3–5 days only. |
| Freezing | Halve, pit, treat with ascorbic acid (1 tsp per quart of water) to prevent browning. Freeze on single-layer trays then bag. 12+ months at 0°F. |
| Drying (classic apricot use) | Halve, pit, optional sulfur dip for color preservation, dehydrate at 135°F for 24–36 hours. Stores 12+ months airtight. Tilton and Moorpark are the traditional drying cultivars. |
| Canning (halves in syrup) | Follow a tested apricot canning recipe, including fruit preparation, jar size, headspace and the processing time for your elevation. Syrup and a sealed lid alone do not establish safe preservation. |
| Jam, Jelly, Chutney | Excellent jam fruit; moderate pectin. Add lemon juice for set. |
| Apricot Brandy / Apricot Wine | 3–5 lb fruit per gallon mead or wine. Traditional in Central Europe and Central Asia. |
Yield Expectations by Tree Age
- Year 3: First handful — 1–5 lb.
- Year 5: 25–50 lb (semi-dwarf).
- Mature (8+ years, standard): 100–200 lb per tree in a good year. ZERO in a frost-killed year.
- Average across years: Plan on 3 out of 5 years producing a crop in Zones 5–7; 4 out of 5 in Zones 8–9 and the Pacific Northwest.
- Productive lifespan: 20–30 years commercial; 30–40 years with care.
10. Companion Planting (The “Apricot Guild”)
Comfrey, clover, and pollinator-attracting herbs round out a classic apricot guild, with adequate spacing and management of competition around the apricot tree.
Apricots integrate well with classic stone-fruit guilds. They tolerate the same broad pH range as most permaculture staples, support native pollinators with early spring bloom, and benefit from companion plants that suppress weeds, deter pests, and improve soil over time.
Companions and Their Roles
Companion | Role in the Guild |
|---|---|
| Comfrey (Symphytum officinale) | Dynamic accumulator, chop-and-drop mulch, pollinator forage. |
| White or Crimson Clover | Nitrogen fixation; living mulch; pollinator forage. |
| Garlic, Chives, Daffodils | Pest deterrent (peach tree borer especially); daffodil bulbs deter voles. |
| Lavender, Rosemary, Sage | Pollinator attractors; pest-confusing aromatic herbs; drought-tolerant. |
| Native Asters, Yarrow, Bee Balm | Pollinator and beneficial-insect attractors. |
| Strawberry or Wild Strawberry | Ground-cover layer; weed suppression; small harvest bonus. |
| Currants or Gooseberries | Understory berry layer; tolerate light shade once apricot matures. |
Plants to Avoid Near Apricots
- Other Prunus species at close range (plum, peach, cherry) — share most of the same pest and disease pressure.
- Tomatoes and other Solanaceae nearby — verticillium wilt host plants.
- Walnut and hickory — assess light, soil, and root competition. Published observations for stone fruits are mixed and do not establish that every apricot near a walnut or hickory will be injured.
- Heavy nitrogen feeders at the trunk base.
11. Regional Growth Profiles
Apricots are most reliable in the Pacific Northwest and California; everywhere else, success comes down to picking a late-blooming or cold-hardy cultivar and siting above the local frost pool.
Region | Recommended Cultivars & Notes |
|---|---|
| Pacific Northwest | Apricot territory. Goldrich, Moorpark, Perfection — all late-blooming, all reliable. The Hood River and Wenatchee Valleys are classic commercial apricot regions. |
| California | California is the apricot heartland. Blenheim is the regional flavor benchmark; Tilton the drying classic; Patterson, Katy, Royal Rosa for the south. |
| Desert Southwest | Low-chill cultivars (Katy, Royal Rosa) for low desert. Mid-elevation Sky Islands: standard cultivars succeed. |
| Intermountain West & Rockies | Apricot is challenging due to late-frost vulnerability and alkaline soils. Harglow and Moorpark on raised mounded sites with iron supplementation; some growers succeed, others lose crops 3 of 5 years. |
| Great Plains | Hardy cultivars (Goldcot, Harglow, Manchurian) in sheltered sites. Eastern Plains better than western High Plains. Manchurian apricot is the cold-hardy choice. |
| Ozarks & Interior Highlands | Late-frost vulnerability is real here. Harglow + Goldcot or Goldrich + Moorpark on south slopes well above frost-pool elevations. |
| Upper South / Mid-South | Tilton, Goldcot, Moorpark, Perfection. East Tennessee mountain elevations work best; lower elevations are frost-marginal. |
| Southeast & Gulf Coast | Generally not recommended — chill hours often insufficient and humidity drives disease pressure. Low-chill cultivars (Katy) may work in Zone 8b–9 inland sites. |
| Mid-Atlantic | Late-blooming cultivars (Harglow, Goldrich, Moorpark) with siting attention. Maryland and Pennsylvania orchards have a strong apricot tradition. |
| Northeast & New England | Apricot is a gamble — Harglow, Moorpark, Goldcot in sheltered south-facing sites. Coastal New England better than inland. |
| Great Lakes & Upper Midwest | Goldcot is the regional standard (Michigan-bred for the Great Lakes). Harglow, Moorpark also reliable. Cold-hardy Manchurian apricot for Zone 3–4. |
Frequently Asked Questions
Do I need two apricot trees to get fruit?
No. Most apricot cultivars are self-fertile, so a single tree will set a full crop on its own. Planting a second variety with overlapping bloom bumps yield about 10–20%, but it’s a nice-to-have, not a requirement.
How long until an apricot tree bears fruit?
Expect your first real harvest in about 3–5 years for a semi-dwarf tree and 4–6 years for a standard. Pinch off any flowers the first year so the tree puts its energy into roots and structure instead.
What hardiness zones can I grow apricots in?
Apricots do best in USDA Zones 5–8, with hardy cultivars like Harglow, Goldcot, and Moorpark pushing into Zone 4 and low-chill types like Katy and Royal Rosa extending into Zone 9. Matching the cultivar’s chill-hour need to your local winter is the key to a reliable tree.
Why do apricots lose their crop to frost, and how do I prevent it?
Apricots bloom earlier than any other temperate fruit tree, often in late February or March, which puts the flowers right in the path of late freezes. Choose a late-blooming cultivar and plant uphill or on a north-facing slope where cold air drains away rather than pools, and keep a sheet handy to drape over the tree on forecast frost nights.
