Care Guide

Watering

Water deeply when the top inch of soil feels dry, ensuring excellent drainage

Fertilization

Apply a balanced slow-release fertilizer as new growth appears. Regular feeding supports continuous blooming throughout the summer.

Banana Peel Tea:Soak chopped banana peels in water for 48 hours. Dilute 1:1 with water and apply to the base to promote blooming. Avoid foul odors by not letting it ferment too long.
Pruning
  • Harvesting/Deadheading: Pull the stems firmly from the base rather than cutting them; this stimulates the rhizome to produce new shoots;
  • Maintenance: Remove yellowing or damaged leaves to maintain airflow and prevent fungal diseases;
  • Winter Prep: In cooler zones, mulch heavily over the crown in late autumn to protect rhizomes from freezing.
⚠️

Pets & Humans
