Watering

Keep soil consistently moist during fruiting season; apply organic mulch to retain moisture

Fertilization

Apply well-rotted manure or compost before new growth emerges. Avoid high-nitrogen fertilizers to prevent excessive leaf growth over fruiting

Banana peel compost tea:Compost banana peels for 2–3 months to break down, steep in water for 24 hours, dilute 1:20 with water for root drenching; avoid raw peels to prevent pest issues
Pruning
  • Remove old, woody stems in late winter to encourage new fruiting wood
  • Thin crowded branches to improve airflow and light penetration for better berry development
  • Cut back damaged or diseased shoots as soon as observed to prevent spread of pathogens
