Proper training of grape vines should be practiced. Many people use trellising to keep the vines off the ground. Trellising is a form of plant training, which is the arrangement of plant parts spatially to optimize productivity. Having the grape vines off the ground “reduces the time that vines remain wet from dew and rain and thus limits the amount of infection”. As the current seasons growth occurs, tie the new growth in a spatial manner to allow for air circulation and sunlight to affect the whole grape plant.
