After planting the Corydalis in open ground, due attention should be paid to caring for the plant. Each type of perennial plant differs in terms of flowering, color and shape, bush height. Recommendations will help prevent mistakes during the preparation of planting material and its planting. Care consists in establishing an irrigation regime, in the timely introduction of fertilizing, processing bushes from infections and pests, and some other measures.
Description and features
Corydalis is considered a herbaceous perennial plant. The name is due to the unusual shape of the flowers, which resemble a bird's crest. The flower is resistant to low temperatures and diseases, does not require special attention and has healing properties.
Corydalis has the following features:
- a powerful root system extends far into the depths and has several branches, some varieties have tubers on the roots;
- stem erect, fleshy, 17-36 cm high;
- the leaves have a deep green color and 2-3 cuts, resemble fern leaves;
- active growth of the bush begins in March;
- a brush of inflorescences is formed in the upper part of the stem;
- each flower has an oblong base, which ends with petals curved outward;
- flowers can be yellow, pink, purple, blue or white;
- flowering lasts three weeks;
- after flowering, the fruit remains in the form of a pod;
- insects with a long proboscis can pollinate flowers.
Decoctions and infusions based on corydalis can relieve inflammation, reduce pain, and stop bleeding.

How to plant
In order for the flowering to be bright and long, you should choose the right site for planting and prepare the planting material.
Selection and preparation of seed
Corydalis seeds, even in good conditions, quickly lose their germination, so they start sowing within the first five days after collection..
When growing seeds for seedlings, you should adhere to the following rules:
- the container is covered with peat and sand;
- seeds are evenly distributed over the entire surface and covered with sand;
- then moisten the soil with a spray bottle and cover the container with a film;
- in the first year after planting, only leaves will appear, but strong sprouts should have grown by spring.
Before planting tubers, they should be carefully examined. Only dense and juicy specimens are suitable for planting.
Ready seedlings begin to be transplanted to an open area only at the end of May, when the threat of night frosts is over, and the soil warms up to +15 degrees.
It is permissible to plant tubers from the second half of June to September. At this time, the tubers are dormant.
For planting the corydalis, a well-lit area in the garden is chosen, which will be protected from through winds. In this case, the water should not stagnate in the soil. The soil should be nutritious, light, with low acidity and good aeration. If the soil is heavy, then coarse sand must first be added.
Planting tubers is best done during flowering. If the tubers are large, then they are deepened into the ground by 14 cm with an interval of 12 cm.If the tubers are small, then the planting depth is reduced to 6 cm.
When growing a corydalis on a land plot, you should organize regular watering, do not forget to weed and loosen the soil, apply fertilizers, and protect against diseases and pests.
The period of active growth occurs in the first spring months. At this time, the soil is still moist, and additional moisture is not required. As soon as the earth dries up, watering is carried out systematically. It is important to avoid stagnation of moisture in the soil.
After watering, the soil is loosened. The procedure prevents the formation of dry crust on the surface of the soil. In addition, due to loosening, air and nutrients are fully supplied to the roots of the plant.
Weeds should not be allowed to grow. They increase the risk of spreading fungal infections and pests. It is best to mulch the soil around the flowers.
If the corydalis is planted in nutrient soil, then additional fertilization is not required. To increase the fertility of the soil, organic matter is introduced into the soil before planting the corydalis.
After the end of the flowering stage, the leaves and stem of the plant turn yellow, wither and die off. To remember the place where the corydalis bushes grew, pegs are placed near them.
Almost all types of Corydalis tolerate low temperatures in winter. But some varieties require additional cover. Therefore, they are covered with fallen leaves, sawdust, pine branches, peat.
Transplant and reproduction
It is best to transplant a flower during a dormant period, but the plant tolerates the procedure well during the flowering period. The bushes are dug up and transferred along with a lump of earth to a new prepared area.
Corydalis propagation occurs by seeds, tubers or by dividing the bush:
- Rhizome division begins in the spring months or in the middle of summer. The bush is dug out of the ground and divided into parts. It is important that each separated part has a bud and a part of the rhizome. The bush is planted to a depth of 8 cm, observing an interval of 12 cm.
- The seed option involves sowing unripe flower seeds. Therefore, you need to try to collect material when the box is still greenish. Otherwise, it cracks, and the seeds spill out onto the ground.
Diseases and pests
The Corydalis has good immunity. But in the case of stagnation of moisture in the root zone, the risk of developing fungal diseases increases.
It will be possible to recognize viruses by the presence of spots and growths on the leaves. They curl, turn yellow and dry. Bushes infected with the virus should be removed from the site and burned. After that, the earth is spilled with a solution of potassium permanganate.
A fungal disease such as rust is recognized by brown and brown raised spots on the leaves and stem of the plant. Gradually, the plant turns yellow and withers. In the fight against the disease, drugs such as "Topaz", "Baktofit", "Atlant" help.
Moles and mice
Rodents damage plant roots and stems. Various methods are used to control pests: pesticides are used, ultrasonic repellents or traps are installed.
Traces of the movement of pests in the form of mucus remain on the plant. They eat the leaves and cause the flower to wilt. In order to prevent their appearance, you should get rid of weeds in time and loosen the ground. If slugs appear, they are caught by hand or traps are set.
Adult worms reach 1.9 mm in length. Their activity leads to the fact that the plant turns yellow and dries up, the tubers crack and become loose. A drug such as "Meliorant Percalcite" helps well against parasites.
Use in landscape design
Corydalis will be a wonderful decoration for any flower bed and flower garden. The plant becomes an excellent addition to flower arrangements on alpine slides and rocky gardens.
