The sort of yield that you will be able to harvest will be determined by how you prune your grape vines.The grape vines will need to be trained to maintain their plant size, shape and productivity, this training is not something that can be done overnight – it takes years to do. If it is not done then you will fine that your vines will be growing all over the place and your yield will not be that good.Now le how to write an article ts get into the training… a trellis will need to be setup for the vine to grow against, this will help the plant to take shape. You will need to make sure that the grape vine grows from one strong main shoot coming from the root, if there are other shoots they they will need to be cut off. Pruning grape vines is all about cutting back shoots, foliage and vines to help you get the best crop of grapes.Tie that main shoot vertiacally to the trellis for growth, in the next dormant period you will prune to develop arms. The arms are two shoots on either side of the main shoot and will need to be tied horizontally to the trellis.Any other shoots that come through will need to be pruned back.
