Pruning time

Once the vines have become fully dormant it is time to prune them.  Pruning the grape vine tells it how many bunches of grapes you want it to produce.  Because of the way grapevines grow and produce fruit, growers must prune annually. Fruit is only produced on shoots growing from one-year-old canes. Therefore, healthy new canes must be produced every year to maintain annual production of fruit, otherwise each year your yield would diminish.
