Wisteria is a vine, related to the pea. Some wisteria vines can grow to a height of 25 to 30 feet when properly trellised. Wisteria produces large clusters of beautiful and fragrant pea-sized flowers in a wide variety of colors. Wisteria can brighten up almost any garden. While it is possible for the home gardener to grow wisteria from seeds, such plants can take up to 15 or even 20 years to bloom. Wisteria grown from cuttings blooms in a much shorter period of time, and fortunately starting Wisteria slips is fast and easy with only a moderately green thumb. Wisteria cuttings taken in early spring are considered softwood cuttings and can be propagated by following advice for starting softwood slips.
Prepare a growing pot by filling it with a mixture of standard potting soil mixed with one-third sand. Water until the soil is damp.
Cut a wisteria slip approximately 4 inches long from the end of new spring growth. make sure to make your cut just below a leaf node. Remove all leaves on the lower 1 1/2 inches of the cutting.
Dip the cut end of the slip into powdered rooting hormone. Allow the hormone to coat the end of the cutting.
Poke a hole 1 1/2 inches deep into your potting mix with your finger or a pencil. Insert the cut end of your slip into the hole you just made, being careful not to disturb the rooting hormone. Carefully pack the potting mix around your slip.
Cut the bottom off of a clean 2-liter soda bottle and then stand the bottle over your cutting like a tiny greenhouse. Place your cutting in an area that is warm and which receives plenty of indirect sunlight during the day. Do not place your greenhouse with your cuttings in direct sunlight. Only add water if the soil shows signs of drying out.
Watch your cutting for signs of new growth. New growth should appear within three to four weeks, sometimes sooner. Allow your cuttings to remain growing indoors for at least four weeks or until they appear healthy.
Dig a hole in a sunny area of your garden approximately 10 inches deep and 10 inches across. Mix organic fertilizer with the soil until your have a mixture that is approximately two-thirds soil and one-third organics. Place the root ball of your wisteria in this hole and cover until the entire root ball is covered. Water and keep the soil moist but not too wet until your wisteria begins growing.
