Care Guide

Watering

Water thoroughly every morning, ensuring roots turn from silvery to dark green.

Fertilization

Apply a balanced, water-soluble fertilizer weekly at quarter or half strength.. Vandas are heavy feeders; regular fertilization is crucial for blooming.

Aquarium Water:Use untreated, fresh water from routine aquarium changes to soak the aerial roots. It provides a gentle, natural source of nitrogen. Avoid if the tank has been treated with medications or high salts.
Pruning
  • Flower Spikes: Cut spent flower spikes near the base of the stem using sterilized tools;
  • Roots: Never trim healthy, firm aerial roots, even if they are long and unruly;
  • Dead Tissue: Only remove roots that are completely dry, papery, or mushy and brown.
