Care Guide

Watering

Keep substrate evenly moist but not waterlogged

Fertilization

Diluted balanced liquid fertilizer every 4 weeks. Avoid over-fertilizing, as this can cause leaf tip burn and damage to the delicate root system

Composted banana peel tea:Soak fully composted banana peels in water for 24 hours; dilute the tea 1:20 with water before applying to the soil to prevent nutrient burn
Pruning
  • Remove yellowing or damaged leaves at the base to improve airflow and maintain plant appearance
  • Trim overgrown aerial roots if they become unruly; avoid cutting healthy aerial roots that aid in moisture uptake
  • Repot in early spring and trim circling, bound roots to encourage new root growth and prevent pot-bound stress
