Hello orchid experts!! About a month ago i put my odbrs. Kenneth Biven orchid outside. Sunburn showed up on most of the leaves and after a while i cut them off leaving leavless pbulbs. However, one leaf and the leaves on the new growth looked fine so i left them. Now a light brown spot is spreading over one of the pbulbs. A similiar spot is on the one remaining older leaf. Would sun spots still be spreading one month after the sunburn? I know on of my dendrobiums also had sunburn, but cutting off the burn seemed to do just the trick. Though i dont care about the leaf too much, I really don't want my already small odbrs. to lose one of its bigger pbulbs. I really hope its not fungus because that sounds horrible to deal with
burns can get worse over time, as the tissue dries out. i would move this one to a shady place and let it recover. too much sun will eventually kill the whole thing.
