Composted banana peel tea:Steep fully composted banana peels in water for 24 hours; dilute 1:20 with water for root drench to avoid nutrient burn
Pruning
  • Remove dead, damaged, or diseased stems in late winter before new growth emerges
  • Thin overcrowded branches to improve airflow and light penetration
