Grapes are easy to propagate

Growing grapes is a great way to add a sweet and tasty addition to your garden. While there are several ways to propagate grape vines, one of the easiest is by rooting cuttings taken from a mature vine. For areas with adequate rainfall, you can start your cuttings in place in your garden or, in drier areas, try starting your cuttings indoors in pots and then transplanting them. Grapes can be started from dormant, new growth vines as they are just beginning to bud.
Obtain your cuttings. Using a sharp knife, take each cutting from a new growth vine, and trim each end to leave about 12 to 18 inches of vine with five to six buds. The cuttings should be about as thick as a pencil.
Prepare your soil. Whether you start your cuttings in your garden or in pots, your soil should be a good blend of peat and perlite. Ensure that the soil is deep enough to insert the cuttings deep enough to stand on their own. Your cuttings should be planted in indirect sunlight.
Prepare your cutting with rooting hormone. Dip approximately 3 inches of the end of the cutting that was closest to the root of the original vine into the rooting hormone.
Plant the cuttings. Insert the treated end of each cutting into the soil until it stands on its own. This is usually about half the length of the cutting. Press the soil lightly around the cuttings and water them in.
Observe your cuttings over the next few weeks. The rooting hormone will stimulate the cuttings to "callus". This is the beginning of the root development process. As time goes on, roots will then form and the buds will send out shoots. Continue to keep the soil moist but do not over-water.
Train the shoots on your grape vines. If you are propagating your cuttings in pots, you can now carefully transplant them. Use a mild fertilizer to encourage continued growth. Each cutting should develop a trunk by the end of the growing season.
