I.m beginner to grow orchids. I bought Tolumnia and Dendrobium 10 days ago.
Tolumnia was filled with coconut husk. i watered it only twice in these days. The leaves started withering. then i found that the husk getting decomposed. so Removed it slowly and filled it with charcoal. Now i'm sprinkling water daily morning. and it becomes dry by night. I have hanged the pot in the window grill. Even then bottom of the leaves becoming brown and leaves withering. what is actually happening with my Tolumnia?
