Any of you ever have a graft do this? Trying to figure out what the deal is. I know the picture is awful so I will try to explain. The rootstock is a three year old seedling that I started from a seed out of a Ambrosia apple. The scion is from a Red Rome that I cut back in February. I made the graft in March, and as you can tell took to the rootstock well. The issue is that all summer the scion will put out buds like it has in the picture but then the ends of the leaves start to turn black and eventually they all die and fall off. It'll sit like that a few weeks, and then new buds will break--but never grow. Any ideas what is going on? I have a few other trees on seedling rootstock that I started without any issues.
