Verbena in the garden
In floriculture, several varieties of verbena are grown and obtained from them
Among the hybrid forms, there are plants with flowers of very different colors. Starting to bloom in early summer, verbena fades with the onset of the first frost. This is what attracts both beginners and experienced florists. In addition, the presence of both low-growing plants ranging in height from 20 cm to tall, more than a meter in height, makes verbena a universal ornamental crop in the garden.
Most often, in temperate climates, vervain is grown as an annual crop. Only straight verbena can be grown as a perennial, cutting off the bushes at the root in the fall.
How to grow verbena seedlings
Soil and seeds
Vervain is best grown with seedlings in advance to ensure that planting material is obtained. The seedling soil should be light enough. To do this, you can mix garden soil with an equal amount of sand. Or buy universal garden soil and mix it with perlite or sand.
To sow verbena seedlings, it is important to know that the seeds remain viable for up to five years. However, after a three-year storage period, no more than one third of the verbena seeds can emerge. You can sow seeds for seedlings without much preparation, but it is still better to play it safe and prepare the seeds for planting.
Most often, preparation for sowing is carried out in two ways:
- seed stratification
- soaking the seeds in a growth stimulant solution
Verbena seed stratification begins approximately five days before sowing. To do this, a piece of cloth is well moistened and the seeds are wrapped in it. All this is placed in a waterproof bag and sent to the bottom shelf or vegetable compartment of the refrigerator. After five days, the seeds can be sown. Before sowing, you can simply soak the seeds for 10 - 12 hours in warm, + 25 + 26 degrees, water. Then transfer the seeds to the stimulant solution for an hour, the "Bud" preparation will do.

Sowing seedlings should not start earlier than the first decade of March. It can be continued almost until the end of April. The seeds are simply laid out on the surface of the soil without embedding in it. Cover the boxes with transparent wrap. To speed up the germination process, the seedling containers must be placed in a warm place.
To do this, it is enough to move them for 48 hours to the radiator. In the future, the seeds are kept at + 19 + 20 degrees, regularly opening for airing and removing droplets of collected water. Seedlings begin to appear at 12 - 20 days.
Immediately after germination, the seedlings need to be moistened. However, this can only be done by spraying them from above. It is important to avoid waterlogging. When the second true leaf appears on the seedlings, the verbena is planted in individual pots. Two weeks after planting, the seedlings are fed with a universal mineral mixture.
Transplanting verbena outdoors
When deciding where to plant vervain in the garden, you need to remember that, in general, this plant is unpretentious. Of course, it will develop best in a good sunny place and on light, fertile soil without stagnant moisture. But you can plant it in almost any corner; for good health, the plant needs to provide drainage and removal of excess moisture. For the device of the drainage layer, crushed stone, expanded clay are suitable.
Verbena tolerates a short-term drop in temperature to -3 quite well, but a prolonged cold snap will be disastrous for it. Therefore, it is necessary to transplant verbena at the end of May, with the onset of stable heat. The selected area is dug up. For digging, 5 kg of humus are introduced per 1 sq. m and a couple of tablespoons of complex fertilizers.
Before planting in the prepared soil, you need to make holes, their size should correspond to the size of the earthen lump. The distance between the holes depends on the type of verbena.
Compact species are placed at a distance of 20 cm, medium ones at a distance of 30 cm, and large ones at a distance of 40-50 cm. Before planting, the hole is spilled with water. Enough 0.4 - 0.5 liters. After that, the bush is installed and the hole is covered with earth, slightly tamping it. Immediately after planting in open ground in dry summers, verbena seedlings are regularly watered before they take root.
Caring for verbena in the garden
In the first half of summer, the plant needs regular watering. In the second half of the summer period, watering is reduced. However, once every 14 days, you need to make complex dressings under the verbena. For the plant to thrive during dry periods, the soil underneath must be loosened regularly. This will provide air access to the roots. To prolong flowering, all old inflorescences are removed.
It should be said that if you dig up a verbena bush in the fall and move it to heat, then cuttings can be prepared from it to obtain planting material from them.In addition to ornamental varieties, you can also grow medicinal verbena in the garden, which is widely used in folk medicine.
