My first Vanda!

[Shadeflower]

Vanda's seem to like to drink a lot but their roots don't like staying too wet so that is the challenge, water them too much and something starts to rot, water them too little and leaves start to shrivel.
I give mine a good spray once a week and let the roots dry completely but one root is always wrapped in a layer of loose damp moss and I make sure this moss stays damp at all times. I'd estimate that my vanda's get 1/4 of their water through weekly spraying and then they drink 3/4 more by sucking it out of the moss.
Once every 3 months I check the root under the moss is ok, if it is degrading I move the moss to a different root.

Like this I achieve the drying out between watering and the plant can never dry out completely.
