I will spray my blue Vanda wih fungicide tomorrow morning. I removed a few more leaves with the black rot and I was so relieved that the stem was very healthy, no sign of rot and there is a tiny bump that might be an aerial root (or wishful thinking). The top leaves are very healthy and the roots are healthy so I think this one will survive...let's see. I gave the roots a good soaking of rainwater, superthrive and regular orchid food and kept the leaves dry.
My pink Vanda is still looking great but one bloom dried already....so might be on its last week of bloom. I gave it orchid blooming food and superthrive.
I enjoyed reading Martin Motes month by month orchid growing tips and Vanda growing tips bookmarked these for future reference. I really don't understand some of the terms but am getting there.
