Attention! When growing Nord Star cherries in lowlands and in waterlogged areas, young shoots of the tree can suffer from frost.
The fruiting period in grafted trees begins 2-3 years after planting. The maximum fertility is observed from 4-5 years of age. The highest yields are possible when growing trees in joint plantings with other varieties of cherry. Average yield is 15-25 kg from 1 adult tree.
The variety is considered late-ripening. The berries begin to ripen in July-August. The fruiting nature of Nord Star cherries is mixed. The main crop is formed on 1-3-year-old branches. Fruits for universal purposes - suitable for fresh consumption and for processing. But most often they are processed - canned compotes, jams, make dried fruits.

Advantages and disadvantages
Like other varieties of cherries, Nord Star has certain advantages and disadvantages.
North Star benefits:
- high dessert quality of fruits;
- small size of the tree;
- early maturity;
- high and stable yields;
- suitability for thickened planting (the distance between trees can be 2 m);
- high degree of self-fertility;
- drought resistance;
- winter hardiness;
- not afraid of recurrent frosts due to late flowering;
- immunity to clasterosporia and coccomycosis.
Ripe fruits are easily separated from the stalk, the separation is dry
Disadvantages of the variety:
- increased acidity of the fruit;
- susceptibility to moniliosis.
In general, the process of planting Nord Star cherries does not have its own peculiarities and practically does not differ from other varieties of cherries. The main thing is to choose the right place for planting a tree, taking into account its varietal characteristics.
You can root Nord Star cherry seedlings both in spring and autumn. The timing will depend on the climatic characteristics of the region. In temperate climates, the optimal planting time is mid-April. In the fall, planting seedlings in such regions is extremely undesirable, as there is a threat of their freezing in winter.
In southern latitudes, on the contrary, planting in the fall is quite possible, the main thing is to carry it out a month before the onset of the first frost. The most optimal period will be mid-October.
Site selection and soil preparation
Cherry varieties Nord Star prefers sunny areas. The variety is not afraid of drought, drafts and strong winds. But at the same time, he does not like the close occurrence of groundwater. There are no special requirements for the composition of the soil, the main thing is that it is fertile and well moistened. Before planting, it should be well prepared. It is necessary to remove all weeds on the site, especially perennial ones.
Advice! It is possible to improve the physicochemical composition of the soil by plowing with compost or manure.
How to plant correctly
The seedlings are placed on the area according to the following scheme: 2 × 3 m. When growing Nord Star cherries on an industrial scale, you should adhere to the 3 × 4 m scheme. This arrangement will significantly improve the light regime.
Cherry Nord Star is an unpretentious variety. When caring for him, the standard agricultural practices for this garden culture are used. The first 3-4 weeks after planting, which are considered as starting weeks, are important for the rooting of young trees in a new place. Regular watering, feeding and pruning during this period directly affect the survival rate of seedlings and their further development.
Watering and feeding schedule
Cherry varieties Severnaya Zvezda easily tolerate prolonged drought, but it is preferable to avoid moisture deficit.
Irrigation schedule during dry season:
- After landing.
- At the beginning of the formation of the ovary.
- 14-21 days before the berries ripen.
Advice! When watering, it is necessary to ensure that moisture penetrates deep into the soil by at least 30-40 cm. Do not water trees during a rainy period, since stagnant moisture can be destructive for them.
Watering a young tree is required
In the first year after planting, the seedling does not need feeding. The tree receives all the nutrients it needs from the soil used for planting. It is recommended to apply the first fertilizers from the second year of life, from the moment of depletion of the soil. The frequency and abundance of dressings should increase as the cherries enter the fruiting stage.
The formation of the crown is one of the important activities for the care of cherries. Pruning old branches and removing dry ones promotes tree growth and increases yields. It is necessary to prune a young tree annually, in the spring, before bud break. The place of the cut must be treated with a garden pitch. On average, the crown formation process lasts 5 years.
The first pruning of a tree is carried out in the year of planting. The 6 strongest branches are left on the cherry, the rest are eliminated. It is important to regularly remove root shoots, infected and unproductive branches.
Preparing for winter
It is recommended to start the main pre-winter preparation at the end of October. The branches of the tree are pressed against the trunk and wrapped in straw, tops or burlap. You can protect the root system from winter frost with snow. For this, a small snowdrift is made around the trunk.
Young seedlings need to be more carefully insulated, since it is much more difficult for them to endure winter frosts. Therefore, in the first year after planting, in addition to the main shelter, the trunk circle is also mulched with peat or sawdust.
Diseases and pests
During the flowering period, Nord Star cherries are highly susceptible to infection with moniliosis. The threat especially increases during long and heavy rains. Fungal disease is provoked by the dying off of individual branches and, as a whole, weakens the tree.
As a preventive measure, trees should be regularly inspected for infected branches and leaves. In this case, the damaged parts of the tree are removed and treated with antibacterial drugs.

Reviews about cherry Nord Star
Olga Ivanova, 59 years old, Stary Oskol
I like Nord Star cherry because it is quite easy to care for it. It is enough to regularly loosen the soil, water and fertilize in a timely manner. Also, the variety is quite resistant to fungal diseases. I carry out preventive spraying in the spring, which is quite enough so as not to worry about the condition of the tree. The harvest is always good, but as for me, the berries are sour. Therefore, we mainly let them be recycled. I can preserve fragrant compotes and delight my grandchildren with delicious jam.
Oleg Moskvin, 49 years old, Moscow region
I planted several Nord Star cherry seedlings 3 years ago, and this year I harvested the first harvest. There were, of course, not too many fruits, but quite enough to feast on and appreciate the taste. The berries are very aromatic, juicy and tasty. Cherry is not afraid of late spring frosts, which happen very often in our climatic region. I also like that the trees of this variety can easily tolerate a long dry period, since I do not manage to water them often. The garden is located in a summer cottage.
