Care Guide

Watering

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

Fertilization

Apply a diluted, low-nitrogen succulent fertilizer once.. Requires very little feeding; excess nutrients can cause weak, leggy growth.

Banana Peel Tea:Steep chopped banana peels in water for 24 hours, strain, and dilute 1:1 with water. Pour directly onto the soil. Discard the solid peels in compost to avoid attracting pests or causing fungal rot at the plant base.
Pruning
  • Wear thick leather gloves and protective eyewear when pruning due to toxic sap and sharp spines;
  • Use long-handled loppers to remove dead or dying basal leaves close to the stem;
  • Snip off the sharp terminal spines if planted near walkways to prevent injury;
  • After the plant flowers and dies, carefully cut down the massive flower stalk and remove the dead mother rosette, leaving the basal pups to grow.
