Sorting out a Dormfelder grapevine
My grapevine has gotten slight out of control and quite big. Tried to untangle it today but it feels like the branches are quite brittle and might snap if I do anything too farsh to them. Can I cut them back quite hard in early spring or can I do it now? Have also a vauge memory that you sould cut off anything above two leaves if there is a bunch of grapes forming on it.
