As early as the 18th century, blueberries were found only in the wild. Breeders later found a way to cultivate this plant. Hardy Blue Blueberries belong to the unpretentious and high-yielding varieties that annually increase popularity in the domestic market.
Description of Blueberry Hardy Blue
Hardy Blue Blueberries are tall crops. The average height of the plant is 2 m. The bushes are not dense, slightly sparse, so the shrub needs regular pruning to stimulate the development of sleeping buds. Shoots are formed in moderation and have an erect shape. The leaves are large, elongated.Their inner part is rough, and the outer one is covered with a small layer of wax coating. The leaf plate is characterized by a rich green tint.

- The average diameter of the fetus is 15 mm.
- Weight between 1–1.5 g.
- The peel is not dense.
- The pulp is juicy.
- The taste is pleasant, sweetness prevails in it.
Hardy Blue yields are high. From the bush, subject to proper agricultural technology, you can collect 4-6 kg of berries. If you can’t pay attention to shrubs every day, then the yield characteristics will drop to 3-4 kg. Resistance to frost reaches –40 ° С. Periodically, the plant may freeze if planting was carried out in the middle or northern strip of the country.
Did you know? Blueberries tend to dye their skin blue. To get rid of it, you need to rub your hands with a brush that is moistened in table vinegar.

- The advantages of the variety are as follows:
- low cost of a sapling (only 130–150 rubles);

- The disadvantages of the Hardy Blue variety:
- Small berries.
- The need for pruning.
- Demanding on the quality of irrigation.

The best time for planting blueberries is the end of March or mid-April (in the southern regions the bushes are planted earlier than in the northern ones). A few weeks before the proposed planting, you need to buy a seedling and prepare the site. It is recommended to purchase planting material from trusted sellers or specialized nurseries.
This will allow you to buy a healthy seedling of the desired variety. Keep in mind that his age should not exceed 2 years. Choose plants with a closed root system. The young seedling should be no more than 70 cm high. After the purchase, you need to soak the roots of the plant in a solution of manganese (40 g per 4 liters of water) to disinfect. Withstand them no more than 5 hours, otherwise you can burn.
When choosing a seat, consider the following features:
- The soil should be acidic and loose.
- Good lighting is needed, so it’s best to plant shrubs on the south side of the garden.
- Protection against drafts is important - planting is carried out at a distance of 3-4 m from obstacles or fruit trees.
Important! Do not use organic matter (humus, manure or compost). Such fertilizers will reduce soil acidity.
On the day of landing:
- A plant is placed inside the well.
- It is installed vertically and covered with soil so that the root neck rises 5 cm above the ground. With its help, the root system will receive air and nutrients from the environment.
- Tamp the soil and pour the seedling 10 liters of water. If the earth has settled, then add more. No voids should form in the hole.
- After planting, pour shrub 15 l of water.
Subtleties of care and ripening
Hardy Blueberry variety is a mid-early crop. Berries ripen in mid-August. In order for the fruits to have a pleasant appearance and high taste indices, it is necessary to properly care for the bushes. Plants will develop on time if they are watered correctly, fertilize on time, cut dry branches and protect from frost.
Also, do not forget about loosening the soil and removing weeds. Weeding the topsoil is necessary every week. This will allow oxygen to better penetrate the root system. Due to air exchange, moisture in the soil does not linger and does not provoke root rot. Weeds must be removed as they appear to reduce pests.
Did you know? Some farmers make honey from blueberries. By its properties, it is not worse than buckwheat, but much more expensive.
Pruning of shoots is carried out in early spring, before the sap flow begins. Cut each branch until its height is 30–40 cm. At least 5 buds should remain on the remaining part of the bush. In the fall, sanitary scraps are carried out, during which shoots that are dry and affected by diseases are removed.
Watering and feeding
Fertilizers are applied regularly, starting from the second year after planting. In early spring, when the snow melts, it is necessary to water each plant with 4 liters of ammonium sulfate solution (200 g per 10 liters of water). The second time fertilizers are applied during the period of fruit formation. To do this, use a solution of potassium sulfate (100 g per 7 liters of water).
The third feeding is carried out at the end of July using magnesium sulfate (400 g per 10 l of water). Shrubs are watered with an interval of 20 days. For each bush use no more than 10 liters of water. If you live in the southern regions where long, dry summers prevail, you can reduce the time between watering to 15 days.
Despite the high resistance of the culture to frost, in certain regions of the country (Moscow region, Siberia, the Urals and the North Caucasus), additional protection is necessary. After planting the bush, lay out 40 cm of mulch, which is created using peat, needles and sawdust pine. Pour the plant with 20 L of superphosphate solution (300 g per 10 L of water) to create a protective layer on the surface of the soil.In regions where the air temperature in winter reaches –60 ° C and above, shrubs should be covered with agrofibre. You can remove it only after the snow has melted. So that the bushes are not covered with stains, every day you need to open the agrofibre for literally 1-2 hours. Airing is a reliable prevention of the appearance of diseases and pests.
Collection and storage of blueberries
The berries ripen at almost the same time (the difference is only 3-5 days), so the entire crop can be harvested at a time. Fruits should be stored in the basement, where the temperature is from + 5 ° C to + 10 ° C. In such premises they will be stored for 5–7 months. You can increase the shelf life by up to 12 months by placing the berries in the freezer.

Pests and diseases
The main diseases that affect Hardy Blue bushes include late blight, gray rot, moniliosis, and stem cancer. As a prevention of the onset of diseases and parasites, you must adhere to all conditions of agricultural technology and regularly inspect plants.
If you notice signs of exposure to the bushes, immediately resort to the help of fungicides:
- To symptoms of late blight include brownish-gray spots that are localized on the leaves. A plaque resembling a spider web also appears on their surface. Treatment is carried out by spraying with "Haupsin" (40 g per 5 l of water).
- Signs of Gray Rot manifest as plaque on the shoots and fruits. Over time, the fruits rot and fall from the bush. In the fight against this disease use "Fitodoktor" (100 g per 4 liters of water).
- Symptoms of Moniliosis - brown spots appear on the leaves, on the surface of which spores of the fungus are located. The fight consists in the treatment of "Mikosan" (30 g per 3 liters of water). Signs of stem cancer include red dots on the leaf plate, which later increase in size. Treatment consists in treatment with copper sulfate (40 g per 10 liters of water).
Among the common pests should be noted leafworm, aphid and chafer.
It is also possible to fight parasites with fungicides:
- Against aphids use "Aktara" (2 ampoules per 4 liters of water).
- Fufanon (30 g per 5 l of water) is considered to be an effective remedy against a leaflet.
- In the fight against the May beetle they use "Actellik" (1 bottle per 7 liters of water).
