Wisteria Bonsai Tree: How To Grow and Care

Sharing is caring!

Wisteria is often grown because it is a vining beauty that can trail elegantly over facades and pergolas. In fact, if you live in the south or another moderate climate, you may have considered growing this plant in your own backyard (or perhaps you already do!). 

But did you know that Wisteria can also be grown as a bonsai plant? Wisteria is particularly well-suited to being grown as a bonsai plant because it has such gorgeous, elegant flowers. 

While you’ll need to take some special care to make sure your wisteria bonsai remains healthy, this is luckily pretty easy to do – with some guidance, of course, that we can provide in this article.

Types of Wisteria Bonsai

There are two types of wisteria that are commonly used for bonsai – Chinese Wisteria, or Wisteria sinensis, and Japanese Wisteria, or Wisteria floribunda. 

While Japanese Wisteria produces large, long flower clusters, Chinese Wisteria offers beauty in its own right, too. 

You will find other cultivars, too (there are more than ten species in the wisteria genus) with colors ranging from pink to white and even dark purple. 

Growing Wisteria Bonsai from Seed or By Propagation

Wisteria can be grown from cuttings or from seed. It is easiest to grow from seed, but it’s important to note that seedings do not flower before they are ten to fifteen years old.

If you choose to cultivate wisteria bonsai from cuttings, grated plants, or air layers, you will enjoy blossoms much sooner. 

How To Care for Wisteria Bonsai

Sunlight

Place your wisteria bonsai in full sunlight during the peak of the growing season. This plant needs a lot of light in order to flower. 

It is a frost-hardy plant when grown in the ground, but unfortunately, wisteria has relatively fragile roots when it is grown in a container.

Therefore, you may want to bring your wisteria plant indoors into a cool location, like a garage, that is sheltered from the frost during the winter months.

Watering

You will need to provide your wisteria plant with lots of water, especially during the growing season. In the summer, you will want to put your bonsai in a shallow bowl.

Fill this up with water when you water your plant. This will help keep the roots moist, which is vital during the drying fall and winter months. 

Fertilizing

You can fertilize your wisteria bonsai once per month with an organic fertilizer that is a solid form. You can also use a liquid fertilizer once per week during the growing season. 

This plant grows quickly and likes being fed often, but you will need to use a fertilizer that is high in nitrogen to get the job done. 

Potting and Repotting 

You can report your wisteria bonsai once every two years while the plant is young. When it’s older, just once every three to five years is fine.

When you pot, prune the roots, but be careful about being too zealous with your pruning when you are caring for older plants. Repot into a container with a standard soil mix with a mostly neutral pH. 

Pruning a Wisteria Bonsai

It’s best to prune a wisteria bonsai in the early spring or after flowering. You will want to wait until the tendrils have grown a bit before cutting them back. 

You can prune the woody structures, like branches and twigs, after the leaves have fallen. You should avoid allowing multiple seed pods to develop on the plant, as this can cause it to expend energy unnecessarily.

Pests and Diseases

Wisteria bonsai is not prone to very many issues, especially if it is grown in the right conditions. However, you may have issues with fungal problems like leaf spot and powdery mildew.

To prevent this, remove affected leaves early on. You might have to occasionally watch out for root rot, too, which can be prevented by proper watering techniques.

Where to Buy Wisteria Bonsai

You can purchase wisteria plants just about anywhere, from local nurseries to online retailers. However, look for those that are cultivated specifically for bonsai and make sure you buy from a reputable retailer. This can prevent problems with disease later on.
