R RedSun Gardener Joined Nov 18, 2014 Messages 191 Reaction score 6 Aug 6, 2015 #4 So far it looks harmless. But I want to know what this is. I did not prune this vine much, and I have two main trunks growing from the original two buds. So not worried about this at this time. Grapeman, have you seen this?
