Care Guide

Watering

Water thoroughly when the top third of the soil is dry.

Fertilization

Apply a balanced liquid fertilizer diluted to half strength.. Feed monthly during the growing season; pause entirely in winter when growth slows.

Aquarium Water Fertilizer:Use dirty aquarium water from routine tank changes to water the plant. It provides gentle, natural nitrogen without the risk of chemical burn. Ensure the water is room temperature and free of aquarium salt or medications.
Pruning
  • Prune stems just above a node to encourage branching if the plant becomes leggy;
  • Remove fully reverted (all-green) leaves to encourage the plant to produce more variegated foliage;
  • Trim away any browned or scorched white patches for aesthetic purposes using sterilized shears.
