Pruning your indoor and outdoor grapes
November and December are the best months for pruning both inside and outdoor grape vines.
If you are training your vine and it’s a newish plant you should tie in the stems you require horizontally to a frame work of wires you have already created.
Training the stems in a horizontal direction will include fruiting spurs and more fruit.
With establish vines first prune out all the damaged and diseased stems. Next cut back the long summer growth stems by 75 percent unless you are planning to extend the range of the vine. Finally prune the main stems back to the fruiting spurs.
