Care Guide

Watering

Water deeply every 7–10 days during active growth and fruiting to maintain consistent soil moisture

Fertilization

Apply balanced slow-release fertilizer in early spring before new growth emerges. Avoid high-nitrogen fertilizers that promote excessive leaf growth over fruiting

Eggshell powder topdress:Crush dried eggshells into fine powder; sprinkle 1–2 tablespoons around the tree base in early spring to boost soil calcium levels
Pruning
  • Prune in late winter to remove dead, diseased, or crossing branches to improve airflow
  • Thin crowded inner branches to increase light penetration for better fruiting
  • Remove root suckers at the base to reduce competition for nutrients and maintain desired shape
  • Trim back overgrown branches to control size and encourage new fruiting wood
