I am trying to take some cuttings from my kiwi vine, in about 2 weeks they root, but when I try to take to dome off they start to turn black at the tips of the leaves and eventually die. I have tried to gradually ween them off the humidity dome but still no luck. Could the potting soil be the problem? should I use something that has no nutrients?
Any help would be great! I'm running out of cuttings fast.
