Major sinkage on this grandi rootstock just in the past week. No signs of rot that I can find and the scion is healthy. I’ve read a few threads that seem to think this behavior is relatively benign but I would like to ask if it would be good to degraft completely now. Or if I cut the pup off to release the weight build up, if that could be a viable solution too. The scion is getting pretty big already and the plan was to let this one flourish on this graft indefinitely, so I imagine getting bigger is only going to exacerbate the sinking. Also the grandi has a colored flower so I would prefer to save it too. Swipe for close up pic.
Thank you for your help
