A Detailed Guide to Wisteria Seed Selection and Propagation Methods

Wisteria, also known as tengluo, zhuteng, and huanhuan, belongs to the legume family. The vine stems of wisteria flowers are dark gray, and older ones develop irregular cracks; the flowers are purple or deep purple, fragrant, and very beautiful. Wisteria is now widely distributed across every region of our country, and it has high horticultural ornamental value and medicinal value. So how do you select wisteria seeds? What propagation methods are there? Let's take a look together below.

1. How do you select wisteria seeds?

Wisteria seeds are brown, round, and somewhat glossy, generally 1.5 cm wide and flat in shape. When planting wisteria, you must choose healthy, plump seeds and discard wisteria seeds that have been stored for too long, to avoid affecting the germination rate of the wisteria.

2. What propagation methods does wisteria have?

1. Cutting propagation

For wisteria cuttings, early spring in March is suitable in southern regions; in northern regions, after the soil thaws in mid-to-late March, before the branches sprout, you can select robust 1-2 year old branches and cut them into sections about 15 cm long as cuttings. Once the branches are ready, simply insert the cuttings diagonally into the seedbed; the insertion depth should be 2/3 of the cutting's length.

After inserting the branches, you need to spray water to keep the seedbed moist. Generally, roots will form about a month after cutting, and the survival rate is very high.

2. Seed propagation

For wisteria sowing, spring is the suitable time. First, choose healthy, plump seeds, and before use, soak the seeds in warm water for 24 hours, then take the seeds out and sow them in spots on the seedbed. After sowing, water them; about 1 month after sowing, the seeds will sprout. The seedlings must be cultivated for 2-3 years before they can be planted out.

3. Division propagation

Wisteria division can be done in spring. When wisteria has just sprouted in spring, growers can separate the robust two-year-old suckers growing from the mother plant's roots, together with their roots, from the mother plant, then pot them separately and plant them elsewhere, watering appropriately after planting.

4. Layering propagation

Wisteria layering can be done in spring. First, select robust, slightly woody branches from the previous year or the current year, and lay the branches flat on the ground, burying them in the soil in a wave pattern.

Then, for the branches buried in the soil, first use a knife to score the bark on the branches, then cover with 12 cm of soil. Branches treated this way easily form roots at the wounded area, and generally after about 40 days they can be separated from the mother plant and planted.

The above is an introduction to wisteria. Nowadays, quite a few friends grow potted wisteria. For potted wisteria, in addition to choosing shorter species and varieties, you should also strengthen pruning and pinching to control the plant and keep it from growing too large. If cultivated as a bonsai, shaping and pruning need to be strengthened even more; when necessary, an old stump can be potted and a superior variety grafted onto it.
