Composted banana peel tea：Steep fully composted banana peels in water for 24 hours; dilute 1:20 for root drench to avoid nutrient burnPruning
- Prune dead or diseased branches in late winter to prevent disease spread
- Thin overcrowded stems to improve airflow and increase fruiting yield
- Remove suckers to maintain desired shape and reduce competition for nutrients
- Trim back long branches after fruiting to encourage compact, bushy growth
