Growth Stages

1

Establishment (Year 1)

12 months

Young tree focuses on root development and branch formation. Minimal flowering; new growth is vigorous and tender.

Remove any flower buds the first year to redirect energy to root establishment. Stake if needed for support. Water regularly and apply 2-3 inches of mulch, keeping it away from trunk.

2

Early Fruiting (Years 2-3)

12-24 months

Tree begins producing flowers in spring and small fruit sets. Growth slows as energy goes to fruit production.

Allow limited flowering but thin heavily to 4-6 fruits per branch to develop quality fruit. Prune to maintain open center vase shape. Apply balanced fertilizer in early spring.

3

Flowering

2-3 weeks

Delicate white to pale pink blossoms appear in early spring before or as leaves emerge. Flowers are self-fertile but benefit from pollinator activity.

Protect young flowers from late frost with frost cloth if temperatures drop below 28°F. Ensure adequate water during bloom. Avoid heavy pruning during flowering.

4

Fruit Development and Growth

6-8 weeks

Tiny green fruits form and enlarge over 6-8 weeks. Fruits gradually develop red coloring and sugar content increases. Size reaches marble to golf ball diameter.

Thin fruits to 1 every 2-3 inches on branch to encourage larger individual fruits. Maintain consistent moisture. Fertilize mid-season with lower nitrogen formula (e.g., 5-10-10). Watch for pest damage.

5

Ripening and Harvest

2-3 weeks

Fruits develop full red color and become soft when gently pressed. Sugar content peaks and flavor is at maximum. Fruits can ripen over 2-3 week period.

Harvest fruits that yield slightly to pressure at stem end. Pick every 2-3 days at peak ripeness. Reduce watering slightly to concentrate sugars (but don't stress tree). Continue pest monitoring.

Common Pests

  • Use kaolin clay spray before flowering. Hand-pick infested fruits. Apply spinosad or neem oil post-bloom. Remove fallen fruit promptly.

  • Handpick beetles in early morning or use Japanese beetle traps away from tree. Apply neem oil or spinosad if infestation is heavy. Avoid pheromone traps near tree.

  • Prune out infected branches immediately. Improve air circulation with open-center pruning. Apply sulfur or copper fungicide at petal fall and 2 weeks later. Remove mummified fruit.

  • Spray forcefully with water to dislodge. Use sulfur powder or neem oil if population builds. Maintain adequate watering to reduce stress.

  • Apply horticultural oil in dormant season. Use neem oil during growing season. Prune out heavily infested branches.

Harvest Tips

Plums do not ripen further after picking, so harvest only when fully ripe and soft to gentle pressure. Pick when they've developed full red color and taste sweet. Harvest in morning when fruit is cool. Ripe plums keep 3-5 days at room temperature or 1-2 weeks refrigerated. Handle gently to avoid bruising.

Fun Facts

  • 🌱 Nanho Petite is a genetic dwarf (true miniature), not a graft-induced dwarf, making it reliably small year after year without special rootstock requirements.
  • 🌱 The name 'Nanho' comes from a region in China known for growing miniature fruit trees, and this variety was developed to bring that tradition to Western gardeners.
  • 🌱 Despite its small size, a mature Nanho Petite tree can produce 20-40 pounds of fruit per year when well-maintained, making it remarkably productive for its compact stature.
