Ok, so it sounds like the light levels are ok, and probably the humidity (for winter anyway). The temps have not be less than 60 F. More water then? Should I soak the cork more often, like once or twice a week? How about the fert? Where I got her they said treat her like a vanda - heavy feeder. Is weekly too much?
She has 4 large pbulbs with leaves (one or two), and all have produced spikes. The root system is extensive around and through the cork mount - white, firm, and healthy, and has been there a while.
Should I remove the yellow leaf and the browning pbulb or up the water and see what happens?
Thank you so much for your input. This is one of my favorites; I'd hate to lose it.
