Background and History

This flowering plant is a part of the Fabaceae family, which is native to Japan, Korea, China, and the United States. Two of its species are from the United States and eight are from Asia. According to historical records, the name wisteria came from Thomas Nuttall, a botanist in the 19th century. He named it after Casper Wistar, a doctor from Philadelphia.

For most people, they grow wisteria because of its ornamental value. It is a perennial vine, which can survive for up to 50 years or more. However, this is one plant that may test your patience as it will most probably take a long time before the flowers will bloom. For this reason, a lot of people tend to start from growing in seedlings. We will discuss more of this in the latter part of this post.

One of the oldest wisterias was found in Japan, which has been around for more than 1,200 years. Because of its long life, it is also a symbol of immortality. As a durable plant, wisteria also signifies the ability of the heart to endure pain. In Shin Buddhism, on the other hand, wisteria symbolizes prayer or thoughtful reverence. Lastly, in Feng Shui, because the wisteria appears as if it is bowing down, it also means honor and respect.

It should be two to three times the size of what you will plant. If you are planting several seedlings, on the other hand, make sure to have ten to 15 feet of space in between each plant. It will also be good to add compost or any organic matter, which will increase the nutrients in the soil. The soil should also be moist and should provide the aeration that the roots need to grow. Plant the seedling, cover it with more soil, press firmly, and water the ground.

Common Pests and Diseases

Poor flowering and wilting are some of the most common problems that are evident in wisterias. There are many reasons for these conditions, but more often than not, it can be because of the diseases and pests that are affecting the plant. Some of the frequent diseases in wisteria include leaf spot, powdery mildew, root rot, crown galls, and cankers.

How to Take Care of Wisterias

Patience is one of the most important things when it comes growing wisteria. Other than this, here are some of the tips to keep in mind so that you can achieve success, even as a novice gardener:

  • Regular pruning is necessary. This will make the plant manageable, especially because it can grow extremely large. If you do not prune it, the plant will look like a distraction in the garden and will lose its ornamental value. The best time to prune the tree is before the start of winter. You have to remove as much as half as the growth from the previous year. However, make sure that you prune only when the plant is already in the growing season. Doing this at a time that is too early will only inhibit growth.
  • It is also necessary to water the plant, which is especially important during the growing season of the plant. In the first year, watering will help to establish the growth of the roots. Increase the frequency of watering during the dry months. Upon establishing, however, you can minimize watering.
  • To encourage better growth of the plant and to supplement the nutrients that it needs, you will also need to apply fertilizer. However, keep in mind that not all fertilizers will deliver the outcomes that you anticipate. As much as possible, stay away from nitrogen fertilizers. The latter will encourage more foliage than flowers. It is best to use fertilizers with phosphorus.
  • If you live in a place where there is extreme winter, you need to find a place with cover or shade. This is going to offer protection from frost. While most varieties can tolerate frost, in extreme cases, it can cause the tree to not produce any flower at all.
  • Mulch and compost will also be essential for the healthy growth of the plant. Every spring of the year, put a layer of compost or mulch around the ground where you plant the wisteria. This will help in retaining moisture and in the prevention of the growth of weeds.
  • Training wisteria is also important for growing the plant. You have to provide trellis so that the plant can grow fully. It is best to grow it on the wall, but be sure to provide horizontal wires. You can also grow it in arches, pergolas, and trees, among other places that can provide support.

Harvesting Wisterias

It is pretty much easy to harvest the flowers of wisteria. All that you need is to cut it from the tip, but make sure that you use only clean scissors. This will help to prevent the transfer of infection or pathogens that can damage the health of the plant. On the other hand, if you will harvest seeds, make sure to pick it from a healthy bloom. All that you have to do is to remove the pods, split it into half by twisting, and the seeds will release from the pod.

Conclusion

Location – this is the most important factor in growing wisteria. Make sure that it is in a place where there is enough space for the plant to grow. Care and maintenance are pretty much very basic, with the most important being regular pruning. The latter will keep the plant compact and in attractive shape.
