How to prune grape vine planted against fence on patio - Cumbria
Our vine has been planted for 5+ years! We just hack it back every spring and feed it with some food we bought when we got the vine. We get lots of new growth but only about 5 tiny grapes at the most! We live in Cumbria and the vine is planted outside on a south west facing fence on the patio. Can anyone give us some advice and help as to how to prune and what care we should be giving it?
