Care Guide
Keep soil consistently moist during active growth; increase frequency during prolonged dry spells
Apply balanced slow-release fertilizer once in early spring. Avoid high-nitrogen fertilizers to prevent excessive leaf growth over flowering
Composted banana peel tea：Steep fully composted banana peels in water for 24 hours; dilute 1:20 for root drench to support bloom development- Prune long, unruly shoots in mid-summer to control growth and encourage flower bud formation
- Cut back winter growth to 2–3 buds in late winter to promote dense, abundant flowering racemes
- Remove dead, damaged, or crossing branches annually to improve airflow and maintain plant shape
- Trim aggressive root suckers to prevent overspreading and preserve main vine health
