Here's my grapevine.
As shown in the photo, it comes over from next door (so I cant feed it) and then goes along the fence on 3 wires. It has also started to go the opposite direction and I am training it up the drainpipe and will have it go over the patio doors.
I moved in last Aug, I didn't prune it and I got a ton of tiny grapes off it.
I don't know how old it is probably at least 3 years old I would say. The main stem on my side is quite woody but it is growing well.
I want advice on how to prune the sideshoots/branches. There are lots of punnets, I don't want to over stress it. Should I cut the tip of the side shoots when they reach a certain size or number of punnets?
