How To Grow Japanese Wisteria Bonsai

Many bonsai enthusiasts love shrubs and vines that highlight flowers rather than branches or foliage of the plant. The wisteria or the Wisteria frutescens grows in the United States Department of Agriculture hardiness zone 6 to 9. Furthermore, it is considered the most popular vine when it comes to growing bonsai. The Japanese wisteria bonsai displays some beautiful purple flowers which tend to bloom up to 12’’. This means that it is best to grow wisteria as large plants (2 to 3 feet tall for a perfect visual balance). In this article, we shall be discussing how to grow Japanese wisteria bonsai.

How to Grow Japanese Wisteria Bonsai

· Create softwood cutting from the wisteria plant during summer when growing a new bonsai. It is highly recommended to cut the softwood root when the temperature is above 70 degrees Fahrenheit.

· Once that is done, you will take the shoot and plant it in a bigger container. By doing so, you will be giving the roots ample space to extend as time progresses. You will then place your container in partial shade; this will allow the branches and trunk to thicken. You will move it to a bonsai pot once the plant has aged and thickened.

· If you desire a new shape, you will start styling your bonsai’s trunk using a wire; you should perform this process with utmost care. It is best to start training it when its root system is well established. It would be best if you shaped the branches by pruning it only. When not cared for, the branches can snap easily despite having a pliable feeling.

· You will transfer your wisteria bonsai tree to a larger container. Use the soil that was used in growing the bonsai when it has grown to 2 feet tall. Your bonsai should have an older tree resemblance despite it being a miniature.

· As you repot your bonsai tree, you should consider pruning the old dead roots along with some live new roots for it to fit perfectly in your pot. By doing so, you will be putting it in a mature, growing phase, which tends to encourage more flowering and produce less vegetation.

· Once the flowering has finished, you should consider repotting your bonsai each year. Most bonsai trees are repotted in early spring prior to new growth. However, when you repot wisteria earlier, it will suffer significantly.

Where to Position Your Japanese Wisteria

It would be best if you considered placing your Japanese wisteria in the shade. However, ensure that it has access to sunlight, especially during morning and evening hours.

Watering Your Japanese Wisteria

Japanese wisteria bonsai requires an excellent water supply when growing, particularly before and after the blooming cycle. Consider setting the pot in a tray of water; this will allow the tree to take the amount of water it requires. Once the topsoil becomes wet, the tray should be removed.

Fertilizing Your Japanese Wisteria 

Japanese wisterias are considered some of the greatest feeders when it comes to bonsai. However, it would be best if you feed your tree with a low nitrogen fertilizer since they trap their nitrogen from the atmosphere. You will promote foliar growth when you feed it nitrogen-rich fertilizer. 

Training Your Japanese Wisteria 

You can train your Japanese wisteria to come up with a shape that will best suit your needs. To do this, you will require performance wiring. By doing so, you will be able to create the desired style and shape; however, this should be done before the blooming phase is complete.

Common Japanese Wisteria Pests and Diseases

There is no doubt that wisteria is a hardy and fast-growing tree; however, it is prone to root rot. Usually, this occurs when the tree is exposed to excess moisture. To prevent this from occurring, you should consider watering your plant when the soil is dry. In addition to that, Japanese wisteria tends to suffer fungal infections such as powdery mildew and leaf spot. To prevent this, you should consider removing the affected leaves early enough. 

Conclusion

Growing a Japanese wisteria bonsai tree is relatively easy; by following the above-discussed tips, you will be able to grow one with the utmost ease. As we conclude this article, we hope that it has been of great help to grow the Japanese wisteria bonsai tree.
