While clearing out some shrubs & bushes and I found a grape vine tangled within the branches which stretch 10-15 feet and must be at least 10 years old. I traced it back to the main stem which is about 25-30 mm thick at the bottom. How should I deal with it to get it growing properly as it is now November here. Should it be cut back short or left to the spring and cut back? How low should it be cut?
TIA
