Provisions for shade are given with the use of arcades, pergolas, trellising, and garden pavilions. Some vines are allowed to grow free standing without any attachment to a trellising structure. Many people use trellising to keep the vines off the ground. It can be espaliered or trained on fences and trellising. This traditional method of trellising means that almost all harvesting is done by hand. Foliage trellising is compulsory and must not exceed 0.6 times the space between the rows. Next, came the trellising and end-post supports.
