Hi all...I have a one zygopetalum that is showing great growth both in its roots and new leads. The problem I am having is that the older leaves are just horrid looking. They are just as black as can be. After doing a forum search and coming up with little, I googled and found many sources that said blackening zygo leaves are usually due to the plant being grown too hot or it being underwatered. I live in the North Bay area of Sonoma Co. CA so I have relatively cool nights and my daytime highs are generally not above the mid-eighties in summer. (I have let the plant dry as is my practice with most all of my others). Have any of you had this problem? I haven't taken a photo of the plant as of yet considering this seems to be the consensus from other sources. Thought I would ask you guys before I dragged out the cam.
hi. im new and i dont live in the us or in the northern hemisphere at all, i live in NZ, but i split and repotted a zygo intermedium a year or so ago and the leaves AND p-bulbs went all black. I too was concerned and put it down to being either too hot or too much sunlight (ive been told its the heat from the sun that damages the plant, not the light, and at the time we were in the middle of a drought) and then just put them outside. Now there is new growth all over the place. I hope i could be of any help-Jordan.
