Easily tolerates frosty winters at temperatures down to -50 °C. During the flowering period, it exhibits frost resistance with temperatures dropping to -8 °C.
According to the description, Corinka is a deciduous bush or low tree. They have a developed widespread root system, located at a depth of about 35-45 cm.
The average height of a serviceberry tree varies between 1.5-5.5 meters. The bark of this plant changes color as it matures, from a whitish color to a dark brown tone. Abundant ovate leaves are attached to the branches using petioles up to 14-15 mm long.
White flowers of 3-10 pieces are combined into inflorescences in the form of a straight brush. They bloom by the beginning of May, when the leaves have not yet appeared. The main fruiting period begins in August. It is quite long, so the berries are harvested almost until mid-September.
You can grow currants yourself from seeds. It is easily propagated by root shoots and also by cuttings. The serviceberry tree is distinguished by its rapid growth. Due to the formation of a large number of root shoots, they require annual removal.
Landing
The crop can be planted in open ground in spring or autumn. Experienced gardeners recommend planting in the fall, as in this case the plant takes root better.
For planting, choose a well-lit area. This will prevent the serviceberry from stretching out in search of enough light, and will also promote a bountiful harvest.
Excellent soil for the plant: loamy or sandy loam. Acidity doesn't matter. The plant cannot be planted in areas with high groundwater, since the root system of the serviceberry goes 2–3 m deep, and excessive humidity leads to its death.
When planting serviceberry in the fall, the site must be prepared in the spring. To do this, remove all weeds from the area, and then keep the area fallow until autumn. Before planting, you should dig up this area, and then apply 40 g of phosphorus and potassium fertilizers per square meter. You need to dig the soil to a depth of 10–15 cm.
How to plant

When digging a hole, throw the top fertile layer to the side; in the future you will fill the root system of the serviceberry with it. Combine the fertile layer with rotted compost and sand in a ratio of 3 to 1 to 1.
Pour 2 buckets of humus, 400 g of superphosphate and 0.15 kg of potash fertilizer into the finished planting site. From the resulting composition, build a mound on which to place the serviceberry seedling.
Spread the roots, then cover them with prepared fertile soil. Lightly compact the soil. After planting, water the plant with a bucket of water, then cover the surface of the soil with a layer of mulch.

It is best to cut shrubs in summer. This method allows you to obtain seedlings faster than others, since the next year small bushes with a branched root system grow from the cuttings.
To propagate a plant by layering, you need to bend a branch to the ground and lightly dig it in. It is recommended to do this in early spring, immediately after the soil warms up. Then next spring it will be possible to separate the rooted cuttings from the mother bush.

To combat tuberculosis, it is necessary to remove weakened leaves and shoots, and treat the sections with 1% Bordeaux mixture (copper sulfate can be used as an alternative).
Phyllostic blotch appears as brown spots on the leaves. To combat the disease, Bordeaux mixture 1% should be used. It is important to remove affected leaves in a timely manner!
If a tree or shrub is overtaken by gray rot, mold spots appear on the leaves. The disease cannot be treated. It occurs if the crop was planted in unsuitable soil (in a place where groundwater lies).
Gray mold is also associated with waterlogging. To avoid illness, you need to add water in moderation. For prevention, you can use Bordeaux mixture and topaz.
