Care Guide

Watering

Water deeply every 1–2 weeks during dry spells; reduce watering during rainy periods

Fertilization

Apply balanced slow-release fertilizer in early spring. Avoid high-nitrogen fertilizers which prioritize leaf growth over fruiting

Eggshell powder top-dress:Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around the tree base and water in thoroughly to release calcium
Pruning
  • Prune in late winter to remove dead, diseased, or crossing branches
  • Thin inner canopy to improve air circulation and sunlight penetration for fruiting
  • Remove suckers from the base to prevent overcrowding and redirect energy to main growth
  • Trim fruiting branches to encourage new growth for the next season's yield
