The majority of gardeners grow wisteria with the intention of having it cover a specific area and climb a specific structure. As long as you train wisteria correctly and keep up the growth, you can grow it on an arbor, pergola, fence, or even a wall.
Whatever the case, giving the thick, weighty vines strong adequate support is crucial. If not, the wisteria will take over and harm or destroy the building.
Training Wisteria to Climb a Wall
Wisteria vines mature to resemble tiny tree trunks rather than thin, airy tendrils. Because of their spiral growth habit, which causes new growth to wrap itself around anything it can grip, including existing vines, this is the case.
You’ll need an anchoring support system that the plant can hold onto and that can withstand its enormous weight if you want to teach Wisteria to climb a flat surface like a wall. The plant will eventually topple or tear down everything that isn’t sturdy enough.
How to Create Wall Supports for Wisteria
- Screw 6-8 inch heavy-duty brackets across the center of the support, spaced about 2 feet apart, starting at least 3 feet below the eaves. This may be done into a wood frame or simply into a wall.
- Add a second row a few feet down. Make extra rows of horizontal supports in accordance with the height of the wall.
- Install galvanized wire to connect each bracket. Each horizontal row should have a wire running along it, with at least one vertical wire running across the middle. The bracket should be used to route the wire so that it is as far away from the wall as feasible.
- Use twine or string to fasten the wisteria vine(s) to the wire. The tendrils from the wisteria will encircle the wires as it develops. The wisteria will have enough of space to twist and get plenty of air and sunlight because you used brackets that were at least 6 to 8 inches wide and secured the wire away from the wall.
Training Wisteria to Climb a Fence
Since wisteria will naturally wrap around links, slats, or posts to climb, training it to grow on a fence is not too difficult. If the fence isn’t sturdy enough, the plant may gradually overpower it and weaken it or even knock it over.
Any kind of support material should be robust and long-lasting, such concrete- or pressure-treated, rot-resistant metal pipe. When the wisteria plant matures, it will be quite difficult to remove, therefore before training your vine to climb, make sure you have a strong, long-lasting foundation.
Similar to how you would train Wisteria to climb a wall, you should use brackets or hooks with wires to give the vines something to twist on while training it to climb a wooden fence. Avoid having the vines wrap themselves around the fence slats if at all possible because this will increase the likelihood of future harm. Additionally, by allowing some space between the vine and the support structure, airflow is improved and moisture is kept from becoming trapped in the wood. Better for the fence and the plant.
It could be a better option to utilize a pergola or some other nearby structure to hold the vine for a chain-link fence. It’s best to avoid taking the chance that the fence will eventually be ripped down unless you are convinced that it is constructed of sturdy tubing that can withstand the enormous weight of a mature plant.
Training Wisteria to Climb a Pergola
A striking option for covering a pergola or other structure is wisteria. Wisteria can easily and quickly provide something special to your lawn or garden with its quick growth and beautiful hanging blossoms.
Make sure your pergola is really solid and sturdy before you start. Pergolas, arbors, and other support structures are frequently entirely engulfed by wisteria or even toppled by it over time.
Use a strong, weatherproof, or pressure-treated material, and anchor the pergola into the ground by placing the posts in concrete, for optimal results. Even while it can appear excessive for a young, little vine, trust me when your Wisteria matures you’ll be happy you added extra reinforcements. It would be advisable to use 2x4s for the other sections and at least 4x4s for the posts when constructing your own pergola.
The pergola should be able to be completely covered by a single wisteria plant. After you’ve planted the new vine, you can let some of the sprouts to start growing and twirling around the pergola and one another. To teach the shoots to develop in the desired direction and maintain control, you must tie them to the pergola once they are long enough.
Simply install eye hooks along the pergola’s posts, spaced about 2 feet apart, to do this. Pass a wire (ideally one between 14 and 16 gauge) through the eye hooks. (On Amazon, you can get plant training kits that come with the hooks and wire.)
To direct the vine shoots upward, tie them to the wire using string or twine. Be careful not to tug the vine too tightly, though. You should leave some space so that the vine can maintain its loose, natural appearance and have room to expand.
You should cut back the shoot tips once the vine has grown to the top of the posts. This will encourage the vine to grow more side branches, and these branches will eventually spread across the pergola’s top. These will eventually develop into your floral vines.
You should be able to take the training ties off the pergola once your wisteria begins to spread across the top. It’s a good idea to remove these ties and wires to prevent any damage as your wisteria grows because leaving them in place could lead the vine to become entangled or stuck behind them.
Training Wisteria into a Tree Shape
It doesn’t mean you can’t admire one of these lovely plants in your own lawn or garden if you don’t have a sturdy framework to hold the weight of a wisteria in disarray. These vines are very adaptable and simple to grow, as I already explained. You may even train them to grow into a tree shape, commonly known as a standard, which will give your collection a genuinely one-of-a-kind and quirky touch.
Get started early because it will be simplest to train your wisteria to grow like a tree when the plant is still a young one. If you want to train your Wisteria into a potted standard, similar to a bonsai tree, you can follow these instructions on a smaller scale. To teach your wisteria to grow into a tree, follow the steps listed below.
Choose A Location
Choose a location in your yard where the wisteria tree will receive a lot of sunlight (at least 6 hours per day) and where the soil can drain well. Make sure your vine is not planted too close to other trees or buildings.
Add Support
Place the wisteria in the ground, and then place a 44-inch wooden post nearby, 1-3 inches away from the root of the wisteria. Your chosen height for the wisteria’s tree trunk must be at least 1 foot higher than the post. To anchor the post to support the tree, you must pound it one foot (12 inches) into the earth with a rubber mallet.
Prune the Trunk Stem
The new tree’s trunk should be made from the strongest and healthiest primary stem. By removing 1/4 of the side shoot that is connected to the main stem, you can remove all of the leaves and side shoots off the stem with a pair of pruning shears.
Stake the Trunk
Holding the new tree trunk against the post, fasten it with a delicate tie or a piece of fabric that is just tight enough to keep it standing. Allow enough space so that the stem can develop and move about. Every 8 inches up the post, add more ties, keeping the stem fastened in a straight line and adding more ties as necessary.
Let It Grow
Continue to remove any side shoots that appear as the new trunk expands, adding more ties as necessary to keep the stem straight and upright, and correcting any existing ties that may need to be moved or tightened due to growth.
Create the Canopy
It’s time to construct the tree canopy once the trunk has reached the top of the post. Just above a growth node, cut the top off the main stem. As a result, side shoots will start to emerge from the stem’s top. Cut the tips off the lateral branches just above the leaf stems after allowing these side shoots to grow out until they have at least 6-7 leaves. This will promote more lateral growth and aid in the development of the treetop.
Trim and Maintain
Trim any side branches that emerge from the trunk farther. When Wisteria is dormant in the winter, you can trim back any dead branches and straighten out tangled stems. Adjust any ties around the trunk, then cut back side shoots to about 12 inches.
How is wisteria trained to grow on a wall?
on a wall. Wisteria should be trained as an espalier with horizontal support wires (3mm galvanized steel) spaced 30 cm (1 ft) apart for the best results when grown against a wall. Plants will develop a robust spur system with time and twice-yearly trimming.
How is a mature wisteria trained?
My initial apartment search in Brooklyn led me to a one bedroom on a peaceful, tree-lined street. The apartment wasn’t particularly noteworthy, but the structure was: The entire brownstone, windows and all, was covered in an impenetrable mass of wisteria. Some strong wisteria vines, which may grow 10 feet or more in a single season, can easily cover a three-story building. Despite its rambunctious nature, a wisteria in full blossom is one of the most beautiful views.
Wisteria may happily twine, climb, and sprawl over anything in its path for a very long time without any pruning. But a trimming routine becomes an essential task for the gardener who has a small yard and wants to enjoy more obvious and many wisteria flowers. Plan on pruning at least twice a year (once in the summer and once in the winter) for best results. Understanding how the vine develops will also help you succeed.
Not everyone prefers to live without windows, but no one needs to if they plan ahead and make a commitment to routine pruning.
Summer: Cut the long shoots after flowers fade
Since wisteria flowers grow on the growth from the previous year, pruning wisterias twice a year not only keeps them in controllable proportions but also develops a network of short branches close to the building so you can more readily enjoy the blooms. Simply cut the long branches from the current year’s growth back to 6 inches in length in the early summer after the vines have flowered to achieve this. Pruning away root suckers, especially on grafted kinds, and totally removing any branches not required for the main framework of the plant should also be done at this time. Depending on how much time you have and how tidy you want your vine to look, you could choose to prune this way once or more regularly during the summer. Remember that wisteria seedpods are ornamental to many gardeners, so you might wish to leave some wasted blossoms remain.
Design Tip
For winter interest, some seedpods may be left on the vine, but if you bring them inside, high temperatures will force them to explode. The pea-shaped fruit was once utilized by a friend as part of a winter arrangement. The following morning, she discovered her cat hiding in a corner from the flying seeds.
Winter: Prune long shoots down to three or five buds
Trim the long stems that have sprouted after the summer trimming to three to five buds in the late winter. Remove any undesired long shoots from the previous season as well; they will be easier to spot now that the framework is leafless.
To focus energy on flower production rather than vegetative development, even short branches should be pruned to three to five buds.
Why your wisteria may not bloom
Wisterias are infamous for not blooming. Make sure these fundamental cultural prerequisites are satisfied before attempting severe measures.
The decision to go with a seed-grown plant rather than a grafted plant is the most frequent cause of a lack of flowers. While seed-grown vines may take up to seven years before flowering, grafted plants normally blossom within three years.
High winds and late frosts can harm flower buds, particularly those of Wisteria sinensis. Wisteria, on the other hand, blooms best following years with hot summers.
Avoid fertilizer with a high nitrogen content. Wisteria fixes nitrogen in the soil like other legumes do. A surplus of nitrogen might result in poor flowering and excessive leaf growth.
Training a new wisteria on a pergola
The plant’s strength allows it to adapt to various forms. Wisteria can be trained against a structure or lattice, molded into a shrub or standard, or planted on a pergola or arbor. Because of its long blossoms, which dangle dramatically through the top of pergolas and arbors, wisteria floribunda is a popular choice. Since it grows so quickly, like other wisteria species, only one plant is typically required to completely cover a structure. However, placing two vines at the opposite ends of a structure provides it aesthetic balance and allows a gardener to showcase two different cultivars on the same structure.
Planning is essential when training wisteria to grow on a pergola or arbor. These constructions must be fashioned of a sturdy, weather-resistant material, such as cedar, and properly anchored in the ground with concrete footings in order to be used effectively. Don’t be scared to overbuild a pergola or arbor because wisteria is notorious for tearing down its supports. I suggest using at least 24 lumber for the crosspieces and 44 lumber for the posts.
Allow two or three young shoots to knot loosely around each other and the post as they grow to start training a new plant onto a pergola or arbor. Since the woody stems grow gnarled and attractive as they mature, this will help give interest to the plant’s structure. As they climb, the young shoots need to be fastened to the post. To do this, fasten a 14-gauge galvanized (or comparable) wire to the post using eye hooks spaced roughly 18 inches apart (or on all four sides for extra support). Use gardening twine to secure the shoots to the wire as they develop. As they develop, give them some breathing room to develop a more attractive habit and avoid having them mature and put a lot of stress on the framework.
The shoots should be headed back (their tips should be pruned) once they have reached the top of the arbor to encourage side shoots that will spread across the tops of the supports and bear flowers. The training ties on the post will no longer be required as the plant matures and becomes more stable across the top of the structure. In order to keep the plant from becoming girdled as it grows, it is a good idea to remove them.
