Care Guide

Watering

Water thoroughly when soil is completely dry; avoid overwatering to prevent root rot

Fertilization

Diluted succulent fertilizer applied once monthly. Use a balanced, low-nitrogen fertilizer to promote leaf health without encouraging leggy growth

Banana peel tea:Soak chopped banana peels in water for 24 hours; dilute the resulting tea 1:20 with water for root drenching; discard solid peels to avoid pest infestations and odor
Pruning
  • Remove dead or wilted leaves at the base to maintain rosette shape and improve airflow
  • Trim leggy stems in early spring to encourage bushier, compact growth
  • Cut back spent flower stalks after blooming to conserve plant energy for new leaf growth
