How to Grow Plum

Plum

Prunus domestica

tree

Plums are stone fruits produced by deciduous trees in the Prunus genus, bearing juicy fruits in colors ranging from yellow to deep purple. These medium-sized trees are relatively easy to grow and produce abundant fruit with proper care and pollination. They've been cultivated for thousands of years and are valued for fresh eating, cooking, and preserving.

Growing Conditions

☀️

Sun: Full sun, 6-8 hours daily minimum; 8+ hours ideal for best fruit production and flavor

💧

Water: Moderate, consistent watering; 1-1.5 inches per week during growing season. Reduce watering after fruit set. Drought-tolerant once established but produce better with regular moisture.

📏

Spacing: 15-20 feet between trees (standard), 10-12 feet for dwarf varieties inches

📅

Days to maturity: 2-4 years to first fruit; 3-5 years for full production

🌱

Planting depth: Plant at same depth as root ball; graft union 4-6 inches above soil line

Soil

Type: Well-draining loamy soil, avoiding waterlogged conditions

pH: 6.0-6.8

Amendments:

Compost or aged manure at planting Mulch for moisture retention Potassium and phosphorus-rich fertilizer

Growth Stages

Dormancy

3-4 months

Tree is bare and leafless during winter months. This is the ideal planting time in many climates.

Plant bare-root trees in late fall or early spring. Ensure good drainage to prevent root rot. Apply dormant oil spray if needed for pest control.

Spring Growth

4-6 weeks

Buds break and leaves emerge; flowers appear in early to mid-spring, typically white or light pink blooms.

Apply balanced fertilizer as growth begins. Monitor for frost damage to flowers. Ensure adequate water as growth resumes. Thin flowers if excessive bloom to direct energy.

Fruit Development

6-8 weeks

After pollination, small fruits appear and begin to enlarge. Flowers drop and fruit swells throughout spring and early summer.

Thin fruits when marble-sized to 2-4 inches apart for larger fruit. Water consistently. Begin applying potassium-rich fertilizer. Thin out crowded branches to improve air circulation.

Ripening

2-4 weeks

Fruit develops full color and softens. Sugar content increases as the fruit matures. Skin color transitions to final hue.

Reduce watering slightly to concentrate sugars. Monitor for bird damage and apply netting if needed. Stop fertilizing to avoid excess nitrogen. Watch for pests attracted to ripening fruit.

Harvest

2-4 weeks

Fruits are fully ripe, soft to gentle pressure, and easily detach from branches.

Harvest ripe fruit daily to prevent overripening and dropping. Store in cool conditions. Prune lightly after harvest to maintain shape. Water well post-harvest to support next year's growth.

Common Pests

Hand-pick infested fruit, apply spinosad spray, use kaolin clay coating before fruit ripens, manage overwinter habitat
Hand-pick beetles early morning, use Japanese beetle traps away from tree, apply neem oil or spinosad spray
Spray with horticultural oil in early summer, encourage natural predators, prune infested branches
Improve air circulation, remove infected fruit and mummified fruit, apply sulfur or copper fungicide in spring, avoid overhead watering
Prune out infected branches well below canker, burn pruned material, apply lime-sulfur in dormancy
Spray strong water stream, apply insecticidal soap, encourage beneficial insects, use neem oil

Uses

🍳

Fresh eating and cooking

Culinary

Plums are delicious eaten fresh and feature in desserts, jams, preserves, and savory dishes. They can be canned, frozen, or dried (prunes). [source]

💊

Digestive health aid

Medicinal

Dried plums (prunes) are traditionally used to support digestive function and contain sorbitol and fiber that promote healthy bowel function. Fresh plums provide antioxidants and vitamin C. [source]

🍳

Wine and beverage production

Culinary

Plums are fermented into wine, brandy, and liqueurs in many cultures. Plum juice and dried plum extracts are also used in beverages. [source]

🏠

Ornamental landscape value

Household

Plum trees provide beautiful spring blossoms and attractive foliage, making them valuable ornamental additions to gardens and landscapes in addition to fruit production. [source]

🦋

Wildlife food source

Wildlife

Plum trees provide nectar for pollinators in spring and fruit for birds and wildlife throughout ripening season. They support biodiversity in food forests and permaculture systems. [source]

Harvest Tips

Plums ripen in summer, typically June through August depending on variety and region. Pick fruit when it yields slightly to gentle pressure but is still firm enough not to bruise easily. For fresh eating, harvest when fully ripe; for canning or cooking, harvest 1-2 days earlier for better firmness. Plums do not ripen significantly after picking, so tree-ripening is important. Early morning harvest reduces bruising. Store ripe fruit in refrigerator for up to 2 weeks.

Fun Facts

🌱 Plums belong to the Prunus genus, which includes cherries, apricots, and peaches—all stone fruits with a single large pit.
🌱 Dried plums are called prunes and have been documented as a food for at least 2,000 years; California now produces over 99% of the world's prunes.
🌱 Some plum varieties are self-fertile but many produce much better fruit with cross-pollination from a compatible flowering variety blooming at the same time.
