📏

Spacing: 240 inches

📅

Days to maturity: 1460-1825 (approximately 4-5 years from planting to significant production)

🌱

Planting depth: Same depth as root ball; graft union should be 2-3 inches above soil line

Soil

Type: Well-draining loamy soil with good depth

pH: 6.0-7.0

Amendments:

Compost or aged manure at planting Mulch layer (2-3 inches) to retain moisture and regulate temperature

Growth Stages

Dormancy & Early Spring

December-March (varies by zone)

Bare branches with emerging pink flower buds; trees are leafless or just beginning to leaf out

Prune during dormancy to establish open center form. Remove crossing branches and dead wood. Apply dormant oil spray to control overwintering pests.

Bloom & Pollination

2-4 weeks (early spring)

Trees covered with delicate pink to white flowers; rapid leaf emergence and branch elongation

Tilton is self-fertile but benefits from cross-pollination. Ensure adequate bee activity. Protect from late frosts with frost cloth if necessary. Begin regular fertilization.

Fruit Set & Early Growth

3-4 weeks

Small green fruits appear where flowers were; trees are in full leaf with vigorous new growth

Thin fruit to 4-6 inches apart when fruits are walnut-sized to promote larger fruit and prevent branch breakage. Remove damaged or diseased fruits. Maintain consistent watering.

Fruit Development & Maturation

4-6 weeks

Fruits swell and gradually change from green to yellow-orange; sugar content increases; tree canopy is fully developed

Continue watering as needed but allow soil to dry slightly between waterings. Provide support with stakes or tree props for heavy-laden branches. Monitor for pests and disease.

Harvest Readiness

1-2 weeks (harvest window)

Fruits reach full golden-orange color with slight give when gently squeezed; aromatic fragrance is present

Harvest when fully ripe but still firm for best flavor and storage. Cool harvested fruit immediately. Prepare for next season's growth by maintaining tree health.

Black walnut Other stone fruits (too close may compete heavily)

Common Pests

Use pheromone traps to monitor populations. Apply spinosad or neem oil at petal fall and every 2 weeks thereafter. Remove fallen fruit promptly.
Prune for air circulation, remove infected fruit immediately. Apply sulfur or fungicide spray at bloom and again 2-3 weeks later.
Spray with strong water stream, insecticidal soap, or horticultural oil in early spring before bloom.
Maintain humidity, spray with water, use miticide if populations are severe. Neem oil can be effective.
Improve air circulation through pruning, remove infected fruit, apply fungicide at first sign of disease.

Uses

🍳

Fresh eating and preserves

Culinary

Tilton apricots are excellent for fresh consumption due to their large size, balanced sweetness, and firm texture. They are ideal for jams, preserves, and canning, retaining their shape and flavor well during cooking. [source]

🍳

Drying and processing

Culinary

The firm flesh and lower water content of Tilton make it an excellent choice for drying whole or halved. Dried apricots retain sweetness and can be rehydrated for cooking or eaten as a snack. [source]

💊

Nutritional and antioxidant benefits

Medicinal

Apricots are rich in beta-carotene, vitamin A, and dietary fiber. They contain phenolic compounds with antioxidant properties that may support eye health and overall wellness. [source]

🏠

Home orchard production

Household

Tilton is a reliable producer that provides substantial fresh fruit for home use, reducing store-bought purchases and providing pesticide-free produce when grown organically. [source]

🦋

Pollinator support

Wildlife

Early spring flowers provide valuable nectar and pollen for emerging bees and pollinators after winter. The tree supports biodiversity in home orchards and gardens. [source]

Harvest Tips

Pick fruits when fully ripe (golden-orange) and slightly yielding to gentle pressure, typically late June to July depending on zone. Harvest into padded containers to avoid bruising. Ripe apricots will detach easily from the branch. For best flavor, allow fruits to ripen on the tree. Can be harvested slightly underripe if needed for storage.

Fun Facts

🌱 Tilton was developed in California and is named after Tilton, Kansas. It gained popularity due to its self-fertility and consistent production, making it ideal for home gardeners.
🌱 Apricot flowers bloom very early in spring (sometimes in late winter), which is why late frosts can be particularly damaging to apricot crops—Tilton is somewhat frost-hardy but still requires frost protection in marginal zones.
🌱 A single mature Tilton apricot tree can produce 80-200 pounds of fruit in a good year, making it one of the most productive fruit trees for home orchards.
