Bad attitude, for one. This is a vine that wants its way in the garden. And prune it hard. Despite its reputation as an invasive bully in the garden, wisteria can be finicky when it comes to performing. Buy a named variety from the nursery rather than generic rootstock. The two most common types of Wisteria—sinensis Chinese and frutescens native to American —have varieties with blue, white, or purple flowers.
Photography by Britt Willoughby Dyer. Early spring before leaves appear is the time to hard-prune wisteria. On a new plant, choose a sturdy vertical-growing vine to be the leader and remove other vertical vines. I have a large concrete light standard in my front yard. Will a wisteria grow up around it and help disguise this eyesore?
Several years ago I planted seeds from a neighbor's pink Wisteria. This year it finally bloomed but the flowers are violet not pink. I'm very disappointed. We had a pink tree when I was a child and they are not as common in our area. My neighbour has one, and it has climbed around a very large pine tree in my yard.
It has grow ALL the way up. She is afraid it is going to chock and kill the tree. Is this true? Thank you! I recently rebuilt a sturdy pergola to support a well-established wisteria vine. Now I want to build a flagstone patio under the pergola.
I am to excavate 4 or 5 inches of soil but I some of the shallower roots will be damaged in the process. Will I seriously damage the vine if I have to cut a few of the roots just below ground level?
I have a beautiful 3 year old blue Chinese wisteria. All of the leaves just died and are falling off. I think one of the shoots found weed killer. I cut the root off. Any suggestions on how to save the tree? Skip to main content. You are here Gardening » Growing Guides. How to Plant, Grow, and Care for Wisteria.
By Catherine Boeckmann. When to Plant Wisteria Plant in the spring or fall, while the plant is dormant.
Wisteria can be grown from seed, but those grown from seed often take quite a few years to reach maturity and produce flowers. Where to Plant Wisteria Plant in full sun. Sunlight is essential. Plant wisteria in fertile, moist, but well-draining soil. If your soil is in poor condition, add compost; otherwise, wisteria will grow in most soils. Learn more about soil amendments and preparing soil for planting.
Choose a site away from other plants, as wisteria grows quickly and can easily overtake its neighbors. Wisteria is also known for growing onto and into nearby structures, such as houses, garages, sheds, and so on. We strongly recommend not planting wisteria too close to your home!
Wisteria vines require a very sturdy structure to climb on, such as a metal or wooden trellis or pergola. Mature plants have been known to get so heavy that they break their supports, so plan with care and build your structure with hefty materials.
How to Plant Wisteria Dig a hole as deep as the root ball and 2 to 3 times as wide. Space plants 10 to 15 feet apart. Caring for Wisteria Each spring, apply a layer of compost under the plant and a 2-inch layer of mulch to retain moisture and control weeds. Some gardeners swear by phosphorus to aid with flowering. Scratch a couple of cups of bone meal into the soil in the spring and then add some rock phosphate in the fall. Read more about soil amendments. Water your plants if you receive less than one inch of rain each week.
To know how much rain you are getting, you can place an empty food can outside and measure the depth of water with a measuring stick. For more blooms, try cutting back the rampant shoots every two weeks during the summer.
Pruning Wisteria Pruning is the secret to good flowering, as wisteria only bloom on new wood. Prune wisteria in late winter. If you want a more formal appearance, also prune in summer after traditional flowering. Wisteria produces its flowers on new growth from spurs off the main shoots. In the process the whole plant can be tidied, trained and tied in so that there are no loose, trailing shoots.
Informally grown, mature plants need little or no subsequent pruning. But for a formally trained plant, cut side shoots back to 6 inches in summer, then shorten them again in winter to 3 buds. Do you have a new wisteria? Cut the vine back severely right after planting. Once the framework is full size, shorten further extension growth in midsummer to where growth began for that season.

Native Wisteria If you are located in North America, consider planting a species of wisteria native to the continent, such as: American wisteria Wisteria frutescens , which grows in Zones 5 to 9. All wisteria cultivars require a position of full sun or semi-shade. A moist, well-drained soil is ideal.
The best time to plant wisteria is in spring or autumn. Before planting, improve the soil by digging in well-rotted organic matter such as garden compost or well-rotted manure. Ideally, plant wisteria against a wall and run galvanised wires across it in order to train the plant. Plant at the same level as it was in the original pot and water in well. Train new growth along the galvanised wires.
Wisterias can be grown in containers but they will never be as successful as those planted in the garden. Choose the largest container you can find and use a good tree and shrub compost. Water well and feed in spring. In spring plants will benefit from a high potash feed to encourage flowers.
Prune wisteria twice a year, in August and February. For the first few years give your attention to training the plant into the support. This involves pruning very low branches out, training in strong side shoots and cutting back side shoots to five buds in early August. Throughout the life of the wisteria cut back any shoots that appear below the graft union right back to the main stem.
The long wispy growth is very evident at this time and if not removed will become a nuisance. When pruning wisteria in February cut back the very same shoots but back to three buds. Few gardeners propagate wisteria as the wait for flowers is too long. However, if you want a challenge, take softwood cuttings in mid spring.
