Care Guide

Watering

Water when the top 2–3 cm of soil is fully dry; increase frequency slightly during prolonged hot, dry periods

Fertilization

Diluted balanced succulent fertilizer applied once monthly. Do not fertilize during winter dormancy, as the plant will not actively absorb nutrients

Banana peel compost tea:Fully compost banana peels before use; dilute the tea 1:20 with water and apply to the soil to avoid burning roots; do not apply directly to foliage
Pruning
  • Trim leggy stems in early spring to encourage bushier, more compact growth
  • Remove dead, yellowing, or damaged leaves to maintain plant health and appearance
  • Cut back overgrown trailing stems to control the plant's size and prevent tangling
