Banana peel compost tea:Compost banana peels for 2–3 weeks, steep in water for 24 hours, dilute 1:20 with water for root drench to boost fruit yield
Pruning
  • Prune dead, diseased, or crossing branches in late winter to improve airflow and sunlight penetration
  • Thin overcrowded branches to encourage fruiting wood development
  • Remove suckers growing from the base of the tree to prevent overcrowding
  • Shape young trees to establish a strong, open canopy for easier fruit harvesting
