In the spring, wisteria blooms ferociously, producing clusters of lilac-colored flowers on fresh growth that develops from spurs off the main stalks. Check out our Wisteria Growing Guide for more information on wisteria maintenance, including planting and pruning.
About Wisteria
Wisteria is a long-living vining shrub with cascades of blue to purple blossoms that, in the spring and early summer, look stunning hanging from a pergola or archway. However, this vine is known to grow fairly heavy and to grow quickly and aggressively, frequently reaching lengths of more than 30 feet. It’s advised not to put wisteria vines too close to your home since they will squirm their way into any crack or crevice they can find.
Beautifully fragrant wisteria flowers offer a feast for the senses. A brown, bean-like pod remains on the plant during the winter after flowering. There are only blooms on fresh growth.
Note: Be careful when planting wisteria! The wisteria plant contains lectin and wisterin, which are poisonous to people, animals, and even pets. If taken in significant quantities, these poisons can result in anything from nausea and diarrhea to death.
Is Wisteria an Invasive Plant?
The wisteria species Wisteria sinensis and Wisteria floribunda, which are not native to North America, are regarded as invasive in several areas. If you want to add a new wisteria to your garden, we advise choosing one of the native North American varieties, such as American wisteria (Wisteria frutescens) or Kentucky wisteria (Wisteria macrostachya), which are excellent alternatives to the Asian species.
Do you want to know how to distinguish between North American and Asian species?
While North American wisteria is not quite as aggressive in its growing tendencies and has smooth seed pods and fruits in addition to more-or-less cylindrical, bean-shaped seeds, Asian wisteria is an aggressive grower with fuzzy seed pods. Another distinction is that the flowers of American and Kentucky wisterias appear in the late spring after the plant has begun to leaf out, whereas those of Chinese wisteria do not.
When to Plant Wisteria
- Plant during the plant’s dormant season in the spring or fall.
- Wisteria can be grown from seed, although plants from seeds frequently take many years to mature and begin to bloom. It is advised to buy wisteria plants that are already established or to begin with a cutting.
Where to Plant Wisteria
- Put a plant in full sun. Even while wisteria will grow in some shade, it won’t likely bloom. Sunlight is necessary.
- Wisteria should be grown in fertile, wet, but well-draining soil.
- Wisteria will grow in most soils unless it is in bad condition, in which case you need add compost. Find out more about soil improvements and getting the soil ready for planting.
- Because wisteria grows swiftly and can easily engulf its neighbors, pick a location apart from other plants.
- Additionally, wisteria is renowned for encroaching on and infiltrating surrounding buildings like homes, garages, sheds, and so on. We highly advise against growing wisteria too near your house!
- Wisteria vines need a very strong support, like a metal or wooden trellis or pergola, to climb on. Plan carefully and use substantial materials to construct your structure because mature plants have been known to become so heavy that they destroy their supports.
Wisteria looks gorgeous growing up the side of a house, but use caution when planting it because it is a very strong vine that will get into any crack or gap!
Caring for Wisteria
- Apply a 2-inch layer of mulch and a layer of compost under the plant each spring to keep moisture in and keep weeds at bay.
- Phosphorus is often used by gardeners to promote flowering. In the spring, work a few cups of bone meal into the soil. Then, in the fall, add some rock phosphate. Study up on soil amendments.
- If you get less than an inch of rain each week, water your plants. (To determine how much rain you are receiving, set an empty food can outside and use a measuring stick to gauge the depth of the water.)
- During the summer, try pruning the out-of-control shoots every two weeks for more blooms.
Pruning Wisteria
- In the late winter, prune wisteria. Remove at least half of the growth from the previous year, leaving only a few buds on each stem.
- Also prune in the summer after customary flowering if you prefer a more formal appearance. On fresh growth, spurs from the main shoots of the wisteria develop its blossoms. Prune all this year’s young shoots back to a spur leaving no more than around about 6 inches of growth. So that there are no free, trailing shoots, the entire plant can be trained, roped in, and otherwise organized throughout this procedure.
- Mature plants that have been cultivated informally require little to no more pruning. However, for a plant that has been formally trained, side branches should be pruned back in the summer to 6 inches, then again in the winter to 3 buds.
- Possess you a fresh wisteria? After planting, aggressively prune the vine. Then, the next year, trim the main stem or stems to a height of 3 feet from the growth of the previous year. After the framework has grown to its full size, midsummer extension growth should be cut back to where it started that season.

The tiny trees known as wisteria are notorious for growing quickly, reaching heights of 3 to 5 feet annually. This tree will begin to bloom three to five years after it is planted.
This little tree grows well in grow zones 5-9. It tolerates a variety of soils and does well in full sun to part shade exposure. To accommodate a mature spread of 10–12 feet, space plants 15 feet apart.
Give this tree lots of room because it is invasive and could suffocate nearby native trees and bushes.
Make sure your Wisteria tree is planted in a location and under conditions that will allow it to grow successfully. Although spring and fall are the best periods to plant, you can grow your wisteria at any time of the year as long as the weather isn’t too harsh.
Although the wisteria tree may thrive in both full sun and partial shade, more sunlight will result in more blossoms. Wisteria are highly versatile and even drought tolerant once they have established themselves, despite preferring moist, well-drained, nutritious soil. For the first two to three months, water thoroughly with a hose around twice a week. A 2 inch layer of mulch will aid in weed control, root protection, and soil moisture maintenance. Apply a slow-release fertilizer in the spring.
Just new growth produces wisteria blooms. Therefore, pruning can help you receive the maximum blooms possible. For optimal results, prune at least half of the previous year’s growth in late winter. Pruning is needed to keep the canopy rounded.
For the first year or so after planting, your wisteria tree might need to be staked. These trees grow quickly, and their canopies can be heavy for young trees.

Wisteria trees are they simple to grow?
Flowering vines can be utilized to obscure a view, provide shade for a quiet area, and enhance the aesthetic of a post or arbor in addition to providing color throughout the year.
Due to its aggressive climbing nature, wisteria needs very strong supports in order to develop without bringing down its trellis or pergola. Be careful while growing wisteria near or onto your home since it will grow into any crack or fissure. And keep in mind that wisteria can be quite challenging to get rid of after it has grown.
How is a wisteria tree started?
I was handed a cutting of my neighbor’s gorgeous wisteria vine to plant on our freshly built arbor, but I have no idea how to take a decent cutting without harming their vine.
Verify that this is the ideal vine for your circumstances. Although most oriental wisterias are hardy in zones 4 or 5, they are unable to bloom since the cold winter temperatures damage their flower buds.
After establishing itself in 5–7 years, the Kentucky Wisteria (Wisteria macrostachys) does reliably bloom in zones 4 and 5. These plants can be extremely invasive in warmer climates, need regular, severe pruning to keep them under control.
Make sure you have ample room and a sturdy support for this out-of-control grower. By taking six-inch cuttings in June or July, you can start new plants. In moist vermiculite, sand, or a well-drained potting mix, the cutting should be rooted. Next to the arbor, plant rooted cuttings directly in the ground. Water often enough to keep the soil moist but not saturated. As the plant becomes established, watering frequency should be decreased.
Alternately, grow the rooted cuttings in a container for a season or two until a more substantial root system appears. Gardeners in the north should bury the pot throughout the winter in a protected area.
Alternately, stack the vine to boost your chances of success. Take one of the trellis’s stems out with care. 9 inches below the growing tip, notch the stem. Leave the top 6 inches of the stem above the ground and bury the remaining section. It can be rooted in the soil around it or in a well-drained soil container placed adjacent to the parent plant. During the process of rooting, keep the stem connected to the parent plant. While the buried stem develops its own root system over the summer, keep the soil moist. The parent vine should be severed from the freshly rooted plant. The newly rooted vine can be relocated to a new spot.
