Care Guide

Watering

Keep soil consistently moist during fruit development to prevent fruit drop

Fertilization

Apply balanced slow-release fertilizer to support new growth. Avoid over-fertilizing, as this can reduce fruiting and increase foliage growth

Eggshell powder topdress:Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around the tree base; water thoroughly to release calcium into the soil
Pruning
  • Prune in late winter to remove dead, damaged, or crossing branches
  • Thin overcrowded growth to improve air circulation and light penetration for fruiting
  • Remove suckers to maintain tree form and direct energy to main branches
  • Trim back long, leggy shoots to encourage compact, productive growth
