Please help!!The stems on my cuttings are starting to turn black!
I have one rose from my friend's funeral that I seriously wanted to root, to keep as a momento of her. I cut the stem into several clippngs using the ziplock bag method. It's been one month tomorrow, and so far three of them had been putting out new growth, and one did die, but 2 of them were looking good until now. The stem is starting to turn black about halfway up, is there anything that can be done to save them? any help would be appreciated. I keep them under a lamp 24/7 on top of my computer printer, with the bags sealed.
