Care Guide
Watering
Water when the top 1 cm of soil feels dry; maintain even moisture during flowering
Fertilization
Diluted balanced liquid feed every 2 weeks. Use a low-nitrogen feed to promote bloom production rather than excessive foliage growth
Banana peel tea：Chop 1–2 banana peels, soak in 1 liter of water for 3 days; dilute 1:10 with water before applying as a root drench to avoid nutrient burnPruning
- Deadhead spent flower clusters regularly to encourage prolonged blooming through early summer
- Trim back faded foliage to ground level after flowering to maintain tidy clumps
