Pick a site for the vineyard. Valiant grapes need at least six to eight hours of direct sunlight daily and should be planted in an area with good drainage. Valiant grapes should be planted on the south side of a structure or a hill for the best results.
Build a vineyard support system. Although grapes can be allowed to run wild, they grow better and produce more fruit if they are properly trained. Hammer 5-foot-tall stakes into the ground. Each plant in the vineyard will need one stake. Run three rows of wires evenly spaced between stakes to give the vines something to grow on.
Plant the grapes, being careful not bend or twist the roots. Dig a hole large enough to accommodate the root system. Bury the grape plant up to its neck (a small joint directly above the root system). Make sure a stake is directly behind the plant.
Fertilize the soil with nitrogen blend of 10-6-4 at a rate of 10 lbs. per 100 feet. Feed the plant two weeks after planting. Once your grape vines are established, they should be fertilized the next year, in early spring, before they start to grow.
Train the vines. As the canes grow, gently twist the vines around the wires of the support system. They will take over from there.
Avoid over-watering. Valiant grapes prefer a dry climate. Moisten the soil with water only when it feels and looks dry.
Net the grapes if birds are an issue. Place netting over the plants to prevent the birds from eating the fruit.
