How to Care for a Wisteria Tree

Overview

Wisteria, a member of the Pea family, blooms in spring or summer, depending upon the variety, in shades of purple, pink and white. The wisteria tree is actually a well-trained vine. Some varieties are grafted vines onto basic stock roots. No matter what variety you grow, wisteria is quite easy to care for as long as you don't over-water or over-fertilize it.

Step 1

Provide your wisteria tree with at least six full hours of sunshine a day.

Step 2

Water a newly-planted wisteria tree several times a week for the first year. After that, water the wisteria tree to keep the soil moist, but not soggy. The tree will require more water during dry periods.

Step 3

Apply a 5-10-20 fertilizer once in the early spring. Wisteria do not need a lot of fertilizer, and may not bloom if given too much.

Step 4

Prune your wisteria tree in the fall. Remove most of each branch, leaving a 6-inch length. Wisteria can withstand a hard pruning, so don't be afraid to cut it back.

Step 5

Support the tree by placing a sturdy stake 1/2 inch away from the trunk and 12 inches into the ground. Secure the tree to the stake using either a flexible tape or the legs from an old pair of panty hose. Use a tie material that won't cut into the flesh of the tree as it grows.
