Are the roots of Vandaceous orchids different from other orchids?

Vandae grow in the wild with their roots hanging in the air. Their roots are thick and fleshy. The roots absorb water from the rain and fill it adequately for future use. Vandae do not have pseudobulbs to store water in their stem.

This is used as an advantage for indoor use of Vandae. The roots are dipped in a tumble of water for a period of 20 minutes untill the roots become green. Once it has absorbed adequate water it is taken out and hanged indoor. This process is repeated every 2-3 days depending on how quickly it dries up. Fertilizers are mixed in water for good absorption.

Vanda roots grows sideways, upwards and between the leaves. The aerial roots absorb moisture and water during misting. It is good to soak the roots at least once every day if they are grown outdoors.

Vandae do not need to be potted in a medium in humid areas. However tree barks, charcoal or organic media are good in dry areas to retain moisture or provide support if they are potted. Vandae can be hanged on a wire without much medium.

Repotting is done when the roots outgrow the pot. Vanda does not need to be potted. However it helps the grower to remove and replace if they are potted.

Vandae could be removed to a larger pot or a hanging basket if the roots have overgrown the existing pot. The roots should be moistened to make it soft and flexible during removal.
