I put all of my Christmas cactus's out side on my porch during the summer and they thrive out doors. About a week ago, I noticed that my large cactus had white "bleach" like spots on a couple of the brackets on the stems. About four of the stems were like this and they were very thin and started to fall off. I checked for bugs and aphids and spiders bout found nothing. None of the other cactus are like this. This is a very large cactus and I don't wan
t to lose it. What can I do? Priscilla
