Care Guide

Watering

Water deeply every 7–10 days during fruit development to prevent fruit drop

Fertilization

Apply balanced organic fertilizer before bud break to support new growth. Avoid high-nitrogen fertilizers late in the growing season to prevent delayed dormancy

Composted banana peel tea:Steep fully composted banana peels in water for 3 days; dilute 1:20 with water for root drenching to support fruiting
Pruning
  • Prune in late winter to remove dead, diseased, or crossing branches and improve air circulation
  • Thin overcrowded fruiting spurs to reduce fruit load and improve individual fruit size
  • Shape young trees to establish an open, vase-like crown for better sunlight penetration
  • Remove suckers from the base to direct energy to the main tree
