Wisteria has beautiful white, pink, lavender or purple flowers and twisted, gnarled stems, making them the focal point of any landscape. There are two choices of wisteria, the Japanese wisteria which is hardy in U.S. Department of Agriculture zones 4 through 8 and the Chinese wisteria is hardy in zones 4 through 9. The differences between these two vines are the flowers. If you want flowers with longer sprays that open gradually, choose Japanese wisteria. The Chinese wisteria's flowers open all at once. The average homeowner can plant and grow wisteria vines.

Choose a planting site for the wisteria. Find an area that has full sun exposure. Also make sure there is something sturdy for the wisteria to grow against such as an arbor or trellis. Wisteria should not be planted near the side of your home, garage or shed, because it can pry the shingles off a roof. If left to grow against trees or bushes, the wisteria can slowly choke them to death.
Dig a hole that is two to three times as wide as the wisteria's container, but make it the depth the same as the container. Scuff the sides and bottom of the planting hole with the edge of your shovel or spade.
Amend the soil with 3 to 4 inches of compost. The compost helps with drainage and adds nutrients to the soil that the wisteria needs to grow.
Fill the hole with water. Allow the water to drain away naturally.
Center the root ball of the wisteria in the planting hole and back fill the amended soil into the hole. Tamp the soil as you push it into the hole to remove air pockets.
Place a 2-inch layer of mulch around the wisteria. The mulch helps retain moisture and keeps the weeds from growing.
Water the wisteria once a week, unless your area has received rain. To keep the wisteria growing well, provide an inch of water. After the wisteria is established, only water the wisteria if it is wilted.
Prune the wisteria late in the winter or very early spring before the buds form. Late in the fall or late winter, remove any dead wood and cut away the crowded branches. Cut the side branches, leaving about a foot of growth on the main trunk and remove any suckers found at the base of the plant. The wisteria can be pruned during the summer after it has finished blooming. Trim the new shoots to keep the vine manageable.
