I have two different bulbophyllums. This one I believe is a jersey. My 2nd time getting this. Had it potted and it turned yellow and died. Now I have it mounted with less moss, and its still turning yellow and dying.
And the last pic is a bulb Lazio, and now the top is turning brown. Idk what to do. They are in a north facing window like my friend suggested. I really want to keep them alive.
