Care Guide
Watering
Keep soil evenly moist during active growth; supplement with water during dry spells
Fertilization
Apply balanced slow-release fertilizer once at the start of growth. Avoid over-fertilizing to prevent excessive foliage growth at the expense of fruiting
Banana peel compost tea：Compost banana peels for 2–3 weeks, steep in water for 24 hours, dilute 1:20 with water for root drenching to support berry developmentPruning
- Prune dead or damaged branches in late winter before new growth emerges
- Thin dense inner branches to improve airflow and light penetration
- Trim to maintain desired shape after fruiting in late summer
- Remove suckers to prevent unwanted spread of the shrub
