Water your vanda orchid every 4 to 13 days, more frequently in the summer and less frequently in the winter months. Vanda orchids prefer to be nearly dry before being watered again.
Mist your vanda with fresh tepid or cool water in a spray bottle to raise the humidity in its immediate area. This is particularly helpful between waterings in summer and when you have the heat on in winter.
Pull yellow dead leaves only when they are wilted and come loose with only a very gentle tug. Cutting off leaves because they are damaged and not dead can spread disease on the plant and damage the root stem.
Allow the bloom and bloom stem to die back on its own before cutting or removing, which draws more of the orchid's energy back into the plant for the next bloom cycle.
Replant your orchid every year or two for health and blooming performance. Gently remove the vanda from its old pot removing all old bits of bark from the roots. Choose a new orchid pot with good drainage at least 2 inches larger than the old pot. Partially fill with orchid charcoal and bark and lower the plant into the pot spreading the roots evenly in the pot. Add more orchid planting mix around the roots, water well and drain.
