Phaius Tankervilliea with dark tips on leaves
I bought this "nun orchid" last year in full bloom and kept it in my sun-room in an east-facing window. It is now re-blooming, but over the winter, the ends of the leaves turned dark brown, almost black, and some of them looked as though they had been shredded by a cat. What could be causing this?
During the winter months, we keep the room open to our living area, and we have a small gas-log heater which we leave on during the day. It is not vented, but I always open a couple windows for ventilation. Could this be the problem?
