Choose the grape seeds for your planting based on the qualities you want from the grape. For example, if you want a sweet table grape, find the actual fruit that has the flavor you enjoy, either from the fruit stand or from a neighbor's plants. Look for the Concord grape if you want to grow a fruit for making jelly or maybe some more strong flavored grapes for making wines. Experiment with the various grapes in the grocery store, but realize that the best success will come from plants that are suited to your regional climate, even though most grapes are very hardy. Look through a list of varieties in the Resources section if you are unsure of which type to grow.
Wrap the seeds in a paper towel and fold it several times on itself. Dampen it with a little water and place it in a plastic bag. Close the bag and place it in the back of your vegetable drawer for three months, mimicking the cold days of winter. Plant the seeds after this time, in a plant pot filled with equal parts sand, perlite and potting soil, setting them just below the surface of the soil. Keep the soil damp and the seedling should appear within a week or two. Move them outside once all danger of frost has passed.
Find a site to grow your grapes where they will get full sun. The soil should be full of organic matter and be well draining. Keep the supports from your vineyard at least 6 feet apart from each other. Sink sturdy 8-foot end posts 24 inches into the ground and drill 1/2-inch holes every 18 inches from the ground up to thread the support wires through. Plant your grape seedlings 4 feet away from each other in rows under the support wires.
Allow your baby grape seedlings to grow for two years before you start pruning them. This will allow the plant to amass enough leaves to support a good root system during that time. Prune back all the growth except for three or four side branches to train to grow along the support wires. Prune these branches back to just beyond three or four buds in the early spring, before the plant starts to bud out. Allow this to be the framework for your vines, cutting out the extra growth each year and keeping the growth restricted to a few healthy branches.
