Wisteria (Wisteria spp.) can be trained as a tiny tree or let to climb over a trellis or arbor structure, but regardless of the plant’s form, they are easily identified by their dripping cascades of purple blossoms. In the spring through mid-summer or in the winter, you can take a clipping from an existing wisteria and grow it as a new plant in your yard. Cutting-based propagation is less expensive than purchasing new plants from nurseries, but you first need to root the wisteria start. Plant hardiness zones 4 through 9 of the U.S. Department of Agriculture support the growth of wisteria.
Can a wisteria clipping be rooted in water?
Placing Wisteria cuttings in water is one of the most popular methods used by individuals to attempt and root them. It’s challenging for these plants to effectively root with this technique, though. Make sure it’s a softwood cutting if you want to attempt to root your wisteria using water. Your hardwood stems shouldn’t be submerged for an extended amount of time.
Put the base of a softwood cutting into a glass of water to keep it hydrated if you don’t plan to plant it right away. If you’re lucky, if you keep the base of the cutting submerged, it might start to produce roots.
Because wisteria dislikes having damp feet, it thrives in well-drained or even sandy soil. The ideal method for allowing your cutting to take root is to place it in a pot.
Taking Wisteria Cuttings
Obtaining the cuttings is the first step in growing wisteria from seed. Wisteria pruning, as previously indicated, can be an excellent source of cuttings, but you can also collect wisteria cuttings from the plant expressly for wisteria plant germination.
It is necessary to cut wisteria from the softwood. The wood in question is still green and lacks a woody bark. There should be at least two sets of leaves on the cutting, which should be 3 to 6 inches (7.5 to 15 cm) long.
Preparing Wisteria Cuttings for Rooting
Remove any sets of leaves discovered on the lower half of the wisteria cutting once you have it. These will be the principal locations where new roots form. The cutting should be trimmed so that the lowest node, which is where the leaves you just removed were, is 1/2 to 1/4 inch (1 to 6 ml) from the bottom. You can remove any flower buds that may be present on the cutting.
Rooting Wisteria Plants
Fill a pot with potting soil that drains properly and has been sufficiently watered. Rooting hormone should be applied to the cutting’s rooting end. Create a hole in the potting soil with a stick or your finger, then insert the wisteria cutting, carefully pressing the earth down around it.
Put some plastic wrap on top of the pot or put the entire pot in a plastic bag to completely enclose it. You might wish to use sticks to prop the plastic away from the cuttings because it is crucial that it not touch the cuts. The plastic aids in retaining humidity, which raises the likelihood that wisteria cuttings will grow successfully.
Put the wisteria cuttings in their pot somewhere where they will get enough of bright, indirect light. When the soil feels dry to the touch, check it periodically and water. Within four to six weeks, the cuttings ought grow have roots.
Knowing how to propagate wisteria properly will make it simple to grow wisteria from cuttings.
How long does it take for a wisteria cutting to bloom?
Wisteria can be grown against a house wall or another robust building, like a sturdy pergola. Wisteria can be grown in a container, but only if done so as a conventional tree and with regular trimming to keep its shape. This is a highly labor-intensive option.
How to plant wisteria
Wisteria can be planted in spring or fall. Plant at the same level as it was in the original pot and water in thoroughly after thoroughly preparing the soil to guarantee a proper root run. Like an espalier fruit tree, tie the stems to horizontal galvanized wires connected to the wall. Remove all but one stem if it is climbing a pergola, and tie this stem to the post.
How to plant wisteria in a pot
Wisterias can be planted in pots, but because they are hungry plants, you will need to feed them frequently. Choose this option only if you’re training your wisteria to be a standard. Use a quality tree and shrub compost and the biggest pot you can fit. Plant at the same height as it was in the first pot and give it plenty of water.
How to care for wisteria
The wisteria plant is ravenous. During the growing season, fertilize once a month with a high potash fertilizer to promote greater flower blooming. Weekly wisteria fertilizer and watering. Use organic mulch in the fall, such as well-rotted horse dung or homemade compost, to protect your plants.
How and when to prune wisteria
Wisteria should be pruned twice a year in August and February. Focus on integrating the plant into the support throughout the first few years. This entails cutting back side shoots to five buds in early August, training in strong side shoots, and removing very low branches.
How to prune wisteria in summer
Wisteria that is pruned in the summer will produce short spurs that will transport the spring blossoms.
- Cut the long, robust shoots back from the base of the current season’s growth to a few buds.
- Choose a few sturdy shoots from young plants (less than three years old) to tie to wires or a trellis.
- Simply cut back side shoots on older wisterias to the base of your strong shoots.
Expert David Hurrion demonstrates how to prune wisteria in the summer in this little video. He demonstrates which stems to cut and how much to remove precisely:
How to prune wisteria in winter
By pruning both in winter and in the summer, you can promote the growth of the short spurs that bear the spring blooms. Anytime between late October and March is the dormant season, so do this.
- Connect fresh growth to the main structure to increase its support
- Cut back the remaining long stems sharply.

How to propagate wisteria
Few gardeners cultivate wisteria; most opt to purchase a plant instead because it can take up to 20 years for a wisteria to bloom from a cutting. However, take softwood cuttings in the middle of April if you’re up for a battle.
- Young stems should be cut into lengths and trimmed to 10 cm, just below a leaf joint.
- Leave roughly four leaves at the top of each cutting after removing the lower ones.
- Fill pots with cutting compost, then fill them with water and let the water drain.
- Cover the cuttings with a clear plastic bag after inserting them into the pots so the leaves don’t contact.
- Make sure the cuttings are kept moist by keeping them in a well-lit area.
- Remove the bag and pot after growth is visible.
Growing wisteria: problem solving
Lack of blossoms is the most frequent issue wisteria gardeners encounter. Expecting blooms before the plant is four years old may be impractical because wisterias take their time to bloom.
David Hurrion provides tips on where to plant your wisteria, how to prune it, and how to feed it to get the most blossoms here.
Will wisteria damage my foundations?
In the spring, a house covered in wisteria looks magnificent. Can the roots harm your foundations, though? In our Quick Tips video, Catherine Mansley from BBC Gardeners’ World Magazine explains:
Is honey a suitable hormone for rooting?
Although there are numerous synthetic rooting hormones, such as liquids, powders, and gels, that can encourage rapid root growth in cuttings, if you want a natural, chemical-free alternative or you’re an organic gardener, you should surely take into account honey as a natural rooting stimulant.
Because it possesses anti-bacterial and anti-fungal qualities, honey functions well as a natural rooting hormone.
Types of wisteria:
There are two varieties of wisteria: Asian and American. Although aggressive growers, Asian wisterias are well-known for their stunning blossoms. American wisterias are less aggressive and still produce beautiful blossoms. Compare the most popular wisteria varieties.
Flower color:
Wisteria comes in a range of colors, such as white, pink, and blue tones, in addition to the well-known purple blossoms. If you believe you have seen a yellow wisteria flower, it was probably a golden chain tree (Laburnum).
Foliage:
Wisterias are deciduous, which means that when the weather becomes chilly in the fall, they lose their leaves. The misunderstanding is occasionally brought on by a different vine known as evergreen wisteria (Millettia reticulata).
Avoid planting aggressive wisterias close to your home as they can cause damage and have even been known to destroy buildings.
Wisterias can be grown in full sun or partial shade, but to promote healthy bloom development, make sure the vines get at least six hours of direct sunlight everyday. If you reside in a colder area, pick a planting location that is protected because a heavy spring frost can harm the flower buds.
Create a planting hole that is the same depth as the plant and twice as wide, then level the plant with the soil surface. Because the vines will soon fill in, you should space your plants at least 10 to 15 feet apart along the support structure.
Wisterias don’t need much care once they are planted to promote healthy growth. Water frequently over the first year until the roots take hold.
After planting, wisterias might take some time to come out of dormancy and might not start to leaf until early summer. They will leaf out at the regular time the following spring, but don’t be surprised if they don’t bloom. Wisterias take three to five years to reach full maturity and may not start blooming until then.
Wisterias grow quickly and can reach heights of up to 10 feet in in one growing season. That works out well if you need to quickly cover a fence or pergola but don’t want the vines to take over your landscape. Regular pruning (once in the summer and once in the winter) not only controls wisteria’s growth but also encourages more robust flowering by creating a framework of horizontal branches and causing spurs to grow at regular intervals.
Cut back the current year’s growth to five or six leaves in July or August, or roughly two months after the plant flowers, to get rid of stray shoots and make short branches that will produce flowers the following year. Summer pruning needs to be done more frequently. Re-prune the plant in January or February while it is dormant by removing two or three buds from the growth from the previous year.
The first few years of wisteria’s growth are crucial for creating the desired framework for the plant’s development. As soon as your wisteria begins to grow, start connecting particular lateral shoots to its support structure. You should also cut down any extra growth. An aggressive pruning may be required on elder plants to promote the growth of new branches. Cut down aging branches to the main primary stem to accomplish this. The spaces will soon be filled with new side branches that can be connected back into the support structure.

Can wisteria grow quickly?
Strong support is necessary for the vines to maintain their rapid growth. When wisteria is established in the right setting, it can grow up to 10 feet each year. It functions best in neutral to slightly alkaline, deep, moist, but well-drained soils.
When should I cut grass?
Softwood cuttings should be taken between mid-spring and early summer. From the middle of fall through the middle of January is when hardwood cuttings are taken.
How to take softwood cuttings
- Fill your pots with compost and water them to get them ready for the cuttings before you take a plant cutting.
- Early in the day, when the plant stems are still wet, take cuttings. Use cuttings as soon as possible after placing them in a plastic bag to prevent drying out.
- If you want to take a cutting, pick a sturdy side shoot that has no flowers and cut a portion that is 5 to 10 cm (2-4 in) long, just below the leaf junction.
- The lower half of the cutting should be completely leafless, and the growing tip should be pinched off.
- Apply hormone rooting powder to the cutting’s bottom end. This lessens the chance of bacterial infection while assisting the cutting in growing roots.
- Make a hole in the center of the compost with the dibber or a pencil, then insert the cutting so that the lowest pair of leaves is just above the soil’s surface. Around the cutting, compact the compost.
- When all of the cuttings have been potted, name them, and either place them in a propagator with a bottom heat of 18–24 oC (64–75 oF) or cover each pot with a clear plastic bag and place it in an area with bright but indirect light. For ventilation, open the propagator vents every day or take the plastic bags off once a week for ten minutes.
- Water the compost frequently to keep it moist but not soggy. Depending on the plant, the cuttings may take six to ten weeks to take root. Examine the drainage holes in the pots for any indications that the roots may be showing.
- After the cuttings have taken root, they should be “hardened off” for two weeks by being kept inside at night and placed outside during the day.
- Replant the cuttings in larger pots once they have hardened off so they can continue to grow until they are big enough to be planted outdoors.
How to take hardwood cuttings
- In the fall, when the plants have lost their leaves and are dormant, take hardwood cuttings. When it’s cold outside, avoid taking cuttings.
- Prepare a small trench outside in a protected area if you intend to take numerous cuttings. This will house the cuttings for the most of the following year. Lay a layer of sand at the bottom of the trench, then backfill it with soil that has been amended with compost to ensure proper drainage. Use containers filled with a 50/50 mixture of multipurpose compost and grit if you only need a few cuttings or don’t have room for a trench.
- Choose a sturdy, pencil-thick woody shoot that has grown this year and cut it off just above the shoot’s base to take a plant cutting.
- Cut the shoot into lengths of 15–30 cm (6–12 in) after removing the tip. At the top of each length, make a slanted incision slightly above a bud. This deflects rain from the cutting and serves as a helpful cue as to which end is which.
- At the bottom of each cutting, make a straight cut right below a blossom.
- Each cutting’s lower end should be dipped in hormone rooting powder.
- So that one-third of each cutting is still visible above the soil’s surface, place the lower ends of the cuttings into the trench or pots. In trenches, space cuttings 15 cm (6 in) apart.
- Till the fall after, keep the cuttings in the trench or pots. Water during dry spells to prevent the compost from drying out.
- The cuttings can be replanted in their ultimate locations once they have developed roots.
What are the best plants to take cuttings from?
There are many appropriate plants to pick from once you understand how to take a cutting from a plant. Many delicate plants, including pelargoniums, petunias, verbena, argyranthemums, and osteospermums, respond best to softwood cuttings. Many deciduous shrubs, such as lavender, rosemary, forsythia, fuchsias, hydrangeas, lavatera, and buddleja, allow you to take softwood cuttings as well.
Most deciduous shrubs, roses, climbers like honeysuckle and grape vines, and fruit bushes like fig, gooseberry, redcurrant, and blackcurrant do well with hardwood cuttings.
