Care Guide

Watering

Water when the top 5–7 cm of soil is completely dry; reduce frequency in high humidity

Fertilization

Apply diluted succulent fertilizer once monthly. Use a low-nitrogen, high-potassium fertilizer to support healthy foliage growth without promoting leggy stems

Banana Peel Tea:Soak dried banana peels in water for 24 hours, dilute the tea 1:20 with water, and apply as a root drench; avoid overfeeding to prevent nutrient buildup
Pruning
  • Trim leggy stems in early spring to encourage bushier, more compact growth
  • Remove dead or yellowing leaves at the base to maintain a tidy appearance and improve airflow
  • Cut back spent flower stalks after blooming to redirect the plant’s energy to foliage production
