Despite its northern origin, garden blueberry is a berry that needs proper care. Only with proper preparation for the winter will it be possible to maintain health and a high level of fruiting of the culture.
Frost-resistant varieties of blueberries
Blueberries are widely used as an attractive ornamental plant, and a berry shrub that gives high-quality and tasty, as well as rich in vitamins and a high yield. For landing on a personal plot, it is advisable to give preference to the most unpretentious and frost-resistant varieties:
- Bluegold - an early ripening variety ripening in mid-July, with a bush height in the range of 120-150 cm and a yield of 4.5-7.0 kg;
- mid-season American variety "Blucrop" - ripens in July or August, differs in bush height within 160-190 cm and productivity of 6.0-9.0 kg;
- high-yielding variety "Blue Ray" - ripens at the end of July, characterized by a bush height of 120-180 cm and a yield of 5.0-8.0 kg;
- grade Bonus - ripening in late July or early August, characterized by a bush height of 150-160 cm and a yield of 5.0-8.0 kg;
- grade "Herbert" - ripens in mid-August, is characterized by a bush height of 180-220 cm and a yield of 5.0-9.0 kg;
- tall variety "Jersey" - ripens in mid-August, characterized by a bush height in the range of 160-200 cm and a yield of 4.0-6.0 kg;
- american grade Duke - ripens in mid-July, characterized by a bush height of 120-180 cm and a yield of 6.0-8.0 kg;
- grade Northland - ripens in the last decade of July, characterized by the height of the bushes in the range of 100-120 cm and a yield of 4.0-8.0 kg;
- grade "Patriot" - ripens in mid-July, characterized by the height of the bushes in the range of 120-180 cm and a yield of 4.5-7.0 kg.

How to care for blueberries in autumn
Features of garden blueberry care in the fall
The berry shrub prepared for winter in the autumn period must be fertilized and trimmed. Equally important is prevention and competent shelter of bushes.
Pruning blueberry bushes in autumn
Young shrubs need a thinning procedure in which all thin and close to the ground branches are cut. At the beginning of the fourth year, medium-intensity trimming is performed., which stimulates an increase in growth, since the culture forms berries only on the growth of the previous year.
Experienced gardeners recommend pruning blueberries exclusively in the early spring, before buds open. With the onset of autumn, sanitary pruning is allowed with the removal of thickening and diseased branches, which are then necessarily burned.
Blueberry dressing with Crystal and other fertilizers
Properly selected fertilizers, including Kristallon, have a positive effect on the productivity of an orchard berry crop and also increase the winter hardiness of plants in regions with severe winters.
However, the last time you need to make nutritional supplements is not later than the last decade of August. At this time, it is best to feed the berry culture with high-quality magnesium-containing garden fertilizers represented by Magbor, Kalimag and Kalimagnesia. Later application of nutrient formulations often becomes the main cause of plant freezing in winter.
About the autumn watering of blueberries
With the onset of the autumn period, the need for watering is greatly reduced, especially in rainy weather. However, in most regions, in the autumn it is recommended to carry out mandatory water-charging irrigation, in which the soil layer should be soaked with water to a depth of about 40-45 cm.
It is important to note, that autumn irrigation activities are always carried out using a special divider, which prevents erosion of the soil and exposure of the root system of the plant. For example, a three-year-old plant will need to use up about five buckets of water.
Preparing blueberries for winter
Even winter-hardy varieties of blueberries are able to freeze out in low-snowy and too frosty winters, so the further productivity and health of the garden berry crop directly depends on how correctly the whole complex of preparatory measures is completed.
Shelter and mulching of bushes
If in the growing region there are very strong and prolonged frosts in the winter, then the bush needs to be covered, since at a temperature of -25-27ºC such a berry crop can freeze, especially if there is not enough snow cover during severe frosts.
Preparation of garden blueberry bushes for winter must begin immediately after harvesting. To this end, the branches of the plant are gently and carefully attracted to the soil, after which a wire or rope loop is thrown on them. The bush bent to the ground is covered with a dense, but breathable burlap, and a layer of ordinary spruce spruce branches is laid on top. If snow falls, it is advisable to pour it over the spruce branches. In regions with not too cold and snowy winters, the berry can not be covered, especially if winter-resistant varieties are grown on the site.

Protection against diseases and pests
Even proper agricultural technology is not able to guarantee complete protection of the plant from damage by diseases and pests, and adverse environmental conditions are factors that provoke weakening of the plant and cause death. For this reason, preventive measures should be given special attention.
Timely and proper sanitary pruning, supplemented with fungicide treatment, are the most effective and convenient measures to prevent the incidence of berry. And to get rid of wintering plant parasites, it is advisable to use modern insecticidal drugsrepresented by Actellik, Karate, Iskra and Mospilan in accordance with the attached instructions.
Technology and timing of blueberry cuttings in autumn
To obtain high-quality cuttings, with the onset of late autumn, annual branches are cut, the diameter of which is 0.5-0.8 cm. Sliced planting material should be stored at a temperature of 0-5 ° C. Wet and ventilated peat is best for storage.
With the onset of spring, cuttings of 10-12 cm long, having about five buds, are cut. The lower cut of the cut is done under the kidney, and then treated with growth stimulants, it is planted in a substrate based on three parts of peat and one part of sand. Cuttings need to be planted with a distance of 5-10x3-5 cm, by means of vertical deepening. Landings are covered with a film.
How to plant blueberries in autumn
Rooted cuttings can be planted in a permanent place in the open ground only after two-week hardening procedures are performed. It is desirable to mulch the planted plants with tree spruce sawdust, which will create the most favorable conditions for the growth and development of blueberries.
