A detailed analysis of four propagation methods for weigela

Weigela has strong adaptability, vigorous suckering, and is easy to cultivate. Choose well-drained sandy loam as the seedling bed. Both 1-2 year old seedlings or cuttings can be planted on ridges to grow large seedlings, with a plant spacing of 50-60cm. After planting, cut back to 10-15cm above ground level. After 3 years of establishment, when the seedling height is above 100cm, it can be used for landscaping. So how do you propagate weigela?

How to propagate weigela:

1. Seed propagation

Harvest the fruit every year in September-October, dry the fruit, rub it apart, and remove debris to obtain the seeds. Before sowing, carry out germination promotion by soaking the seeds in cold water for 2-3 hours, then wrapping them in a damp cloth to sprout.

Sow on a windless day, using either broadcast sowing on the bed surface or drilling in rows. After sowing, the soil covering must not be too thick. Keep the bed surface moist within 30 days, and seedlings will emerge in about 20 days.

During the seedling growth period of weigela, weeds must be pulled and pests removed frequently. Propagating weigela by sowing takes a relatively long time to grow, and it is generally used for mass propagation.

2. Cutting propagation

The cutting method is a commonly used technique for propagating weigela.

Weigela is generally propagated by softwood cuttings in summer, in June to July. Select thick, strong branches and cut them into cuttings about 15cm long, keeping only the upper 2-3 leaves. Prepare a sand bed, which can also be a peat moss seedling bed. After insertion, set up a shade curtain, and pay attention to heat preservation and moisture retention. Generally, roots will form more than 20 days after insertion. Hardwood cuttings can also be done in spring in March, and the survival rate is also very high. Cutting seedlings generally bloom in 2-3 years. #p#Subtitle#e#

3. Layering propagation

The layering method is also a simple and easy propagation method.

The branches of weigela are prostrate in form. Select healthy weigela branches, remove the outer bark, and press them into the soil during the growing season, waiting for them to take root. After rooting, separate the branch together with its roots from the mother plant in the spring of the second year, and replant it.

4. Division propagation

Division propagation of weigela can be carried out in early spring and in autumn and winter. It is generally done in spring when the plant resumes growth, in combination with transplanting.

When propagating weigela by division, dig out the entire plant, divide it into several clumps with several plants per clump, and plant them separately.

How to propagate weigela: propagation methods for weigela

Have you seen weigela? Weigela is a common flowering shrub in the north. Weigela has strong adaptability, does not demand much from the soil, and is relatively easy to grow. Let's take a look below at the propagation methods for weigela.

1. Propagation of weigela - cuttings

In summer, you can cut off part of a weigela branch, insert half of the branch into the soil, then water it thoroughly, and keep the soil moist. During the plum rain season, you can cut off some softwood branches; at this time the survival rate of cuttings is relatively high. In spring, you can use the hardwood cutting method, cutting weigela into about 15cm lengths and inserting them into a prepared seedling bed, or use one-year-old branches for open-field cuttings, which root relatively easily.

2. Propagation of weigela - layering

Layering can be done at any time. It generally involves pressing down the branches below the flowers; when the branches are close to the soil, they easily become prostrate, and the nodes of the branches readily take root.

3. Propagation of weigela - division

The best seasons for division are mainly autumn, winter, and early spring. Dig out the entire weigela plant and plant the divisions separately. In spring, one-year-old mature branches can be used for open-field cuttings, or in summer weigela softwood branches can be used for cuttings in a cool place or under a shade shed. Remember that when transplanting weigela, in spring and autumn it should be kept with native soil, and in summer it should be kept with a soil ball, so it survives more easily.

4. Propagation of weigela - sowing

For sowing, do it in early to mid-April. After sowing, water frequently to keep the soil moist. Do not use a spray bottle to spray water, as it will wash the seeds out of the ground, and then no seedlings can grow. Seedlings emerge about 15 days after sowing. Weigela grows relatively slowly, so the sowing method is generally not used.

Four propagation methods for weigela

I. Cuttings

To plant variant types of weigela, we usually use cuttings. In summer, cut 1-2 year old dormant branches into cuttings about 13cm long, then dip the cuttings in a 2000mg/kg solution of a-naphthaleneacetic acid, insert the cuttings about halfway into the soil, then water, and afterward simply keep the soil moist.

If planting weigela in the rainy season, use relatively tender branches, which also need to be cut to a length of about 16cm. Note that before cutting, they should be disinfected, and also pay attention to the drainage of potted plants to avoid water accumulating in the pot soil and causing the plant to die.

II. Sowing

The first step is seed collection. Seeds are generally harvested in September-October. After harvesting, dry the capsules and rub them apart, then remove impurities by winnowing to obtain pure seeds. The second step is seed treatment, commonly known as germination promotion. One week before sowing, soak the seeds in cold water for 2-3 hours, then take them out and place them indoors to sprout. If they are wrapped in a damp cloth to sprout before sowing, the effect is even better. Note that sowing should be done on a windless day and when no heavy rain is expected in the near future, and the bed surface should be leveled and finely prepared. Finally, do not forget seedling-stage management. When the seedlings grow three to four fibrous roots, the first thinning can be carried out, and afterward remember to loosen the soil and remove weeds in time.

III. Layering

For layering, usually strong branches from the lower part of the plant are selected, and their outer bark is removed. This is because the lower branches easily become prostrate, so the nodes take root and survive relatively easily.

IV. Division

Division is generally carried out around spring in combination with transplanting. As the name suggests, division means digging out the entire plant, dividing it into several clumps, and growing each separated clump separately.
