How to Plant Chinese Wisteria Sinensis in Texas

Overview

Wisteria sinensis is a deciduous vine that blooms in clusters of fragrant, purple-blue flowers in the spring. Chinese wisteria is a long-lived plant that has no preferences to sun or shade, soil texture or moisture. Because it is so hardy (USDA zones 3 to 9) it is considered, in some states, invasive. In Texas you will need to be conscientious of the plant's water needs, especially during particularly hot, dry periods.

Step 1

Decide which type of support system you will use for the Chinese wisteria. This can be a trellis, wire, pergola or arbor. Horticulturists at Ohio State University suggest that you use sturdy materials such as treated wood, galvanized copper or aluminum wire. Purchase the materials or completed support system as it will need to be installed prior to planting.

Step 2

Choose a location in which to plant the Chinese wisteria. Although the plant isn't particular about sun or soil, it tends to bloom better in at least six hours of full sun per day. In Texas, because of the intensity of the summer sun, it is best to plant in an area where it will receive morning sun and afternoon shade.

Step 3

Have your soil pH tested at your county's Texas AgriLife extension office. As of 2010, there is a $10 fee for a routine analysis, which includes the pH test. You will also receive recommendations on appropriate soil amendments to use to adjust the pH of your soil. Wisteria requires a soil pH of 6.0 to 7.0.

Step 4

Prepare the planting area by digging up a 3-foot wide, 18 to 24-inch deep area. A long-handled gardening fork is an appropriate tool for this task as you can use it to crush any large clumps of soil.

Step 5

Mix in the soil amendments suggested by the soil pH analysis. These can include compost, peat moss or manure. Scientists at Ohio State University suggest that the soil in the planting area should contain, by volume, one-third soil amendments.

Step 6

Install the support system that you have chosen.

Step 7

Remove the Chinese wisteria from the pot. Set the roots into the hole so that the plant will be growing at the same depth as it was in the nursery. If the tree is grafted, look for the graft union (small swelling or raised bump) toward the bottom third of the trunk. The graft union should be 1 to 2 inches beneath the surface of the soil.

Step 8

Fill the hole with soil and tamp lightly around the base of the Chinese wisteria with your feet. Water until the water puddles at the base of the plant and then give it 1 inch of water per week.

Step 9

Spread a 3-inch layer of mulch around the base of the Chinese wisteria, but don't allow it to touch the bark of the tree. Mulch is an important component in Texas landscapes as it helps to keep the soil moist and roots cool.
