How to propagate verbena? A detailed introduction to the common methods

Cuttings propagation

When we carry out cuttings propagation, we generally choose May and June each year, because the temperature during this period is suitable and the survival rate of cuttings propagation is high. Select robust and vigorous old branches, cut them into long strips, then insert them into loose, moist sandy soil, water promptly, keep the soil moist, and be sure to provide shade; only after 2 to 3 days can they receive a little bit of sunlight. A small amount of mild light can promote the growth of the cuttings, and after about two weeks they can produce roots and new shoots.

Seed propagation

The survival rate of verbena propagated by seed is relatively low, because the seedlings grown from seed sprout slowly and grow poorly. When propagating by seed, choose spring to do it, bury the seeds in loose, fertile soil, then place them in a dark place, water an appropriate amount, keep the air moist, and if the seeds survive, they can bloom around July.

Now that you have learned the propagation methods of verbena, do you know how to care for it during propagation?

How to propagate verbena, the propagation methods of verbena

Verbena is a perennial herbaceous plant, loved by people for its graceful form and rich flower colors. In the process of cultivating verbena, how to propagate verbena has become a rather difficult matter for everyone, so let us learn about the propagation methods of verbena together.

The growth habits of verbena:

Verbena likes sunlight and is not tolerant of shade; it is relatively cold-tolerant, has poor shade tolerance, and is not drought-tolerant. In the north it is mostly cultivated as an annual herbaceous flower, and it can bloom normally in the hot summer. It grows in sunny, loose, fertile soil and blooms profusely. It likes a warm, humid climate and sunlight, is not tolerant of drought, and has low requirements for soil, but in loose, fertile, relatively moist neutral soil it can root at every node, grow vigorously, and bloom profusely. In Shanghai, in places with a relatively warm microclimate, it can overwinter outdoors.

The propagation methods of verbena:

1. Seed propagation: Verbena can be propagated by seed in both spring and autumn, mainly by indoor pot sowing. Select 350 to 390 seeds per gram, and keep the temperature between 20 and 22 degrees, which is suitable for germination. Before sowing, mix the seeds with New High Lipid Film; after sowing, no soil covering is needed, just scatter a shallow layer of vermiculite, which can both retain moisture and allow light through, then combine with spraying New High Lipid Film to retain moisture, which can increase the seedling emergence rate of the seeds.

After 14 to 20 days from sowing, verbena begins to germinate. During the seedling stage, field management should be strengthened, and after 30 days the seedlings can be transplanted. After transplanting, the seedlings should be promptly sprayed with New High Lipid Film to prevent evaporation of aboveground water. If the seedling body does not transpire water, it can isolate pests and diseases, shorten the seedling recovery period, and enable the plant to quickly adapt to the new environment and grow healthily.

2. Cuttings propagation: This type of propagation is best done from May to July. Cut slightly mature branches from the plant, 8 to 10 cm long, and insert them into a sand bed. Before cutting, spray the plants with cuttings seedling treatment for disinfection and sterilization. After cutting, move them indoors, keep the temperature between 15 and 18 degrees, and provide slight shade.

After 14 to 21 days from cutting, the plant begins to take root; after 30 days it can be transplanted into pots. After transplanting, also promptly spray New High Lipid Film to prevent evaporation of aboveground water, and the water in the young shoots can also be effectively prevented from transpiring, thereby isolating pests and diseases, shortening the seedling recovery period, and enabling the plant to quickly adapt to the new environment.

If verbena is watered repeatedly after sowing, its germination rate will be reduced, so it is best to water the soil thoroughly before sowing, and after sowing just maintain soil moisture and air humidity. In winter, the plant can be moved indoors to overwinter, and the next year it can serve as a mother plant for propagation cuttings.

Spring and autumn are the peak growing seasons for verbena. In summer high temperatures it often enters a dormant state and has little demand for fertilizer and water, so in summer fertilizer and water should be controlled; on rainy days or in low-temperature weather, the watering interval can be longer or no watering at all. Watering should be arranged as much as possible in the morning when the temperature is lower, and at night the leaves should be kept dry.

Through the above introduction by the editor, I do not know whether everyone has understood the propagation methods of verbena, and I hope it can help everyone!

How to propagate verbena, verbena cuttings and seed propagation methods

Verbena can be propagated by sowing and cuttings. For these two propagation methods, flower lovers can choose a suitable propagation method according to their own conditions. Below is a summary of the instructions for sowing and cuttings propagation of verbena.

The sowing time for verbena is generally in spring. Usually after sowing, it can bloom around July, but with the sowing method, the seed germination rate of verbena is relatively low, about 50%, and germination is slow and uneven. If at a temperature of 15-17°C, seedlings only begin to emerge two to three weeks after sowing.

As long as the temperature is suitable, verbena cuttings can be done all year round. First select slightly lignified branches, cut them into 5~6 cm long sections as cuttings, insert them into a wet sand bed, and immediately provide shade afterward. After 2~3 days, they can receive a little morning and evening sunlight to promote growth, and after about two weeks they can send out new shoots and take root.

The suitable time for verbena cuttings is from November to March of the following year, and the survival rate of cuttings is as high as 100%; next is September—October, with a cuttings survival rate of 80—85%; the lower cuttings survival rate is in May—August, at 10—25%. Based on observations over the past year and combined with its growth characteristics, take corresponding measures and choose a suitable cutting time.
