Care Guide
Increase watering frequency during fruit development to keep soil consistently moist but not waterlogged
Apply balanced slow-release fertilizer when new growth emerges. Avoid over-fertilizing, as excessive nitrogen can promote foliage growth at the expense of fruit production
Composted banana peel tea：Soak fully composted banana peels in water for 24 hours; dilute the tea 1:20 with water before applying as a root drench to avoid nutrient burn- Prune dormant vines in late winter to remove dead, damaged, or crossing branches and shape the vine for optimal light exposure
- Thin excess new shoots in early spring to improve airflow and direct plant energy to productive fruiting canes
- Remove suckers growing from the base of the vine to prevent energy loss and encourage focused growth on main canes
- Trim back overgrown branches in summer to maintain desired size and prevent overcrowding on trellises
