Coreopsis belongs to the Astrov family. Homeland - States of America with a temperate climate. Planting does not require special skills and care for the bush is simple. Due to this, they are often decorated with gardens, summer cottages.
Botanical Description of Coreopsis
Coreopsis is a perennial or annual rhizome. The stems are thin, highly branched 0.4-0.9 m.
Green leaves are maple-shaped or dissected to the main vein, lanceolate or narrowed. They grow on the lower half of the stems, located crosswise.
Yellow, brownish-red, pinkish and raspberry flowers with a dark spot in the center begin to form in June. They are simple and terry. They have 8 linear, narrowed petals with serrated ends. The end of flowering occurs only at the first cold.
In place of the flowers, flat seed bolls appear. They contain up to 5 hundred seeds. From Greek, coreopsis is translated as bug-like. This is due precisely to the fruits that are similar to these insects.
Types of Coreopsis
The genus includes about a hundred varieties, but not all of them are suitable for cultivation in our climate. In Russia, the following coreopsis are bred:
| Type and description | Varieties | Leaves | Flowers / Flowering Period |
| Large flowered Shoots erect, branching. Requires transplantation every 3 years. |
| Basal - simple. Cirrus-dissected located on the stem. | Golden yellow, the core is darker. On strong pedicels. From midsummer to cold weather. |
| Lanceolate Branching shoots form a bush up to 60 cm. |
| Simple, lanceolate, petioles. | Yellow, on drooping inflorescences. July-September. |
| Whorled Up to 1 m. Able to grow without transplant for about 6 years. |
| Pale green, needle-shaped, sessile. | Needle, reed, sunny shade. Collected in stellate inflorescences. July to October. |
| Auriculate Up to 40 cm. |
| Simple, medium sized. Cover the stem halfway. | Golden, small, similar to daisies. From 2 months of summer until mid-autumn. |
| Pink Thick bush. |
| Skinny, linear. | Pinkish, in the center of the canary color. June-September. |
| Dyeing An annual bush with a thin, branched stem. | No grades | Narrowed, elongated. Grow to the middle of the stem. | With corrugated petals, amber with a dark red middle. July-October. |
| Drummond 40-60 cm. | Large, bright lemon with a reddish-brown core. July. | ||
| Golden baby Up to 40 cm. | On petioles, lanceolate or almost linear. Rising to the top of the trunk, they begin to thin. | Yellow, terry, orange in the center. From midsummer to fall. |
Landing of coreopsis in the open ground
The bush is planted in a lighted place. In the shade, he may die. For abundant flowering, take loose, light, medium fertile soil.
Perennial is best sown with seeds. In order for the bush to bloom in the 1st year, in winter the planting material is placed in small containers, which are left in a warm room until spring. When the snow falls, seedlings are planted in open ground. Special care for the shoots is not necessary. It is enough to provide young bushes with bright light and regular moisturizing.
If you decide to sow seeds immediately on the street, this is done in spring or autumn. Planting material tolerates low temperatures. The first shoots are thinned out and subsequently monitored so that weed grass does not interfere with the development of the bush.
Care for coreopsis in the garden
The shoots of coreopsis grow rapidly, so the bush is divided every 3-4 years and transplanted to a new place. Shallow pits are dug in the ground, between them 0.5 m retreat.
Adult plants are resistant to drought, they do not need to be watered often. Only if necessary, when the soil will crack from drying out. Varieties with pink and reddish flowers are watered more abundantly.
The soil around the bush is regularly loosened. Fertilizer is applied only to poor soil once a year in July. Mineral mixtures are used, organics are undesirable for coreopsis.
Species with long, thin stems are tied up. Otherwise, they will break under strong gusts of wind. Wilted inflorescences are immediately cut off. Thanks to this, the buds can begin to form in the same year.
In the cold season, the stems are cut off under the base, with the exception of the large-flowered coreopsis, it can freeze. It needs to be dug, transplanted into a container and brought into the room. The plant is winter-hardy and calmly tolerates frosts. However, in the north it is advisable to cover the bush with spruce spruce branches or foliage. During the thaw, the root system may rot due to melting snow. Therefore, around the bush you need to make small ditches for draining excess water.
Reproduction of coreopsis
The flower is bred by dividing rhizomes, cuttings or seeds. The first method is preferable, since it is simpler and more productive. Spend it in early spring, as soon as the snow melts:
- Loosen the soil around the bush.
- Carefully take out the plant so as not to damage the root system.
- Divide the rhizome with a sharpened knife so that 2-3 buds remain on each shoot.
- Seedlings. Carry out the same care as an adult bush.
Propagation by cuttings is carried out in June-July:
- Trim healthy shoots with several leaves 10 cm below the internode.
- Remove greens from the bottom.
- Place cuttings in containers (no more than 3 in 1 pot).
- Keep in partial shade, water when drying the top layer of the earth.
Seed propagation method step by step:
- In March, evenly distribute the seed over the surface of the nutrient substrate.
- Press into the ground with a small plaque.
- Cover with polyethylene or glass to create greenhouse conditions.
- Remove the shelter daily for ventilation and watering. When the first shoots emerge (after about 10 days), remove the film or glass completely.
- After the appearance of a pair of real leaves, transplant in separate pots.
- When the crops grow to 10-12 cm, re-pick.
- Land in open ground in May. After hardening the young bushes (daily take out for several hours on the street).
Diseases and pests of coreopsis
Coreopsis is susceptible to the following diseases and insect damage:
| Description of the problem | Cause | Methods of struggle |
| Spotting. |
|
| Fusarium |
|
| Rust. |
|
| Viral infection. |
|
| Aphid. |
|
| Defeat by bugs and caterpillars. |
|
If you provide optimal conditions of detention, proper care, coreopsis will not be afraid of these lesions. To prevent the settlement of insects on the flower, it must be regularly inspected for the presence of their larvae.
