Care Guide

Watering

Water deeply but infrequently, allowing the soil to dry out completely between waterings.

Fertilization

Apply a diluted, low-nitrogen succulent fertilizer once at the start of the growing season.. Avoid over-fertilizing, which can cause weak, leggy growth.

Banana Peel Tea:Soak chopped banana peels in water for 24-48 hours, strain, and use the liquid to water the plant. This provides potassium to support root health and blooming without excess nitrogen. Discard peels in compost to avoid attracting pests.
Pruning
  • Remove spent flower stalks at the base to maintain a tidy appearance;
  • Prune back leggy stems in early spring to encourage bushier growth;
  • Carefully remove any dead or rotting leaves from the base to prevent fungal issues.
