Think you are right to much sun on the Vanda ,it is hard to over water a Vanda in a basket mine are watered 2 times a day .I would do as you said and shade if off . I have found even where I am in Mo. they will burn and dehydrate in direct sun . About the Dend. I would also shade it hopefully it will start a new growth from the base of the old . Gin![]()
