Care Guide

Watering

Water deeply 1–2 times weekly during fruiting; apply mulch to retain soil moisture

Fertilization

Apply balanced organic fertilizer in early spring before new growth. Avoid high-nitrogen fertilizers that promote excessive foliage growth over fruiting

Composted banana peel tea:Compost banana peels for 2–3 weeks, steep in water for 24 hours, dilute 1:20 for root drench; avoid raw peels to prevent pest attraction
Pruning
  • Prune fruited canes to ground level in late winter to make space for new growth
  • Thin new canes to 4–6 per plant to improve airflow and increase berry size
  • Trim 10–15 cm from the tips of new canes in summer to encourage lateral branching and fruiting
