Care Guide

Watering

Water thoroughly when the top inch of soil feels dry, ensuring excess water drains completely.

Fertilization

Apply a diluted balanced fertilizer to support new foliage growth.. Feed monthly during the active growing season; pause fertilization during winter.

Aquarium Water Fertilizer:Use untreated, dirty aquarium change water to hydrate the plant. It provides gentle, natural nitrogen without the risk of chemical burn. Avoid using if the fish tank has been treated with medications or high salts.
Pruning
  • Remove yellowing or damaged leaves at the base of the petiole to maintain aesthetics and prevent disease;
  • Snip off spent inflorescences to redirect the plant's energy back into foliage production;
  • Trim any rotting or dried aerial roots during repotting, using sterilized shears.
