Hi all,
I have this problem with my Vanda. First with my Vanda Limbata and second with my Vanda hybrid (forgot the full name). The tip gotten black and it failed to bloom to the maximum.
It started when I moved this orchids out of my growing area (60 - 70% shade) to somewhere with 80 - 90% shade (under the palm leaves so it didn't get under the full afternoon sunlight). The leaves look fine, they didn't get burnt or something but the blackened tips are what bothers me the most.
What did I do wrong? Could it be that Vanda inflorescence before completely bloom doesn't tolerate relatively high light?
I haven't grow Vanda for very long. I grow dendrobium hybrids this way for a while and don't appear to bother the inflorescences.
