Advantages of highbush blueberries

Another advantage is its tendency to shoot. There is no need to spend money on new seedlings, because propagating shrubs yourself is very simple. In just a few years, the plantation will be replenished with young plants.
However, we must remember that in the middle zone and in the north of Russia it is necessary to grow early cultivated varieties. It is these plants that will be able to produce a bountiful harvest in difficult climatic conditions. In the south of the country there is no such problem.
Features of fruiting
Almost all varieties of highbush blueberries bear fruit on last year's shoots, which is why it is so important to preserve them in winter. If the branches are frozen, then they are cut off quite a bit. The bush recovers quickly. However, if there is a severe defeat, you will have to forget about the harvest.
The young shrub begins to bear fruit in the 3rd year of cultivation, however, the maximum harvest is harvested in the 5th-6th year.
Many hybrid varieties are self-pollinating. They do not need insects, the formation of fruits does not depend on weather conditions. However, in order to increase the number of fruits, experienced gardeners practice joint planting of crops of different varieties with the same flowering period.
How to propagate highbush blueberries
Highbush blueberry reproduces in different ways:
- seeds;
- cuttings;
- basal shoots;
- dividing the bush.
However, seed propagation is difficult; seedlings are grown for 2 years in greenhouse conditions, after which they are transferred to the garden. This plant begins to bear fruit 7-8 years after planting.
The simplest and most accessible ways to propagate blueberries are cuttings and planting root shoots. The seedling will begin to bear fruit in the 4th year of cultivation.

Recommended timing
You can plant tall blueberries in early spring or autumn.

It is carried out in the spring, while the buds have not yet blossomed. Over the course of the season, the bush will strengthen well, grow and successfully withstand winter frosts.
Choosing a location and preparing the soil for highbush blueberries
Highbush blueberries are grown in well-lit areas. In the shade, the berries become small and do not have time to ripen. Fruiting of the bush decreases, in some cases it stops completely.
The southern side of the site is allocated for planting, well protected from drafts and cold winds.
The shrub is unpretentious to soils, but does not tolerate proximity to other crops. It is better to keep the soil fallow for several years before planting.
Before planting, the area is dug up and mineral fertilizers are added. To make the soil looser, sawdust is added.
How to properly plant tall blueberries in spring or fall
Planting in spring is not much different from autumn. You need to choose the right seedling. It is better to purchase seedlings with a closed root system. They are settling in well.
This shrub cannot be planted by transshipment. Before planting, blueberry seedlings are soaked in water to completely free them from the earthen clod and straighten the roots. The plant will not be able to develop its roots in the ground on its own. The root system is very fragile.
The size of the planting hole is standard - 60 x 60 cm. At the same time, the depth of the hole reaches half a meter. If it is planned to plant several plants, then leave up to 1.5 m between them. At least 3.5 m should be spaced between the rows.
The bottom of the pit is filled with a nutrient substrate mixed with sawdust, pine needles and sulfur. During planting, the root collar is buried 3 cm.The roots are straightened, the remaining voids are filled with soil.
Rules for growing highbush blueberries
Highbush blueberries do not require special care, but some nuances need to be taken into account when growing. The shrub is demanding of soil moisture, so watering is an important part of its care.
Watering and fertilizing schedule
Watering highbush blueberries should be plentiful and the soil should always remain moist. However, within 2 days all moisture should be absorbed. Otherwise, a fungus will develop on the roots, which will cause rot. It is considered correct to water blueberries 2 times a week. You need to be especially attentive to soil moisture during the fruiting period. If there is not enough moisture, the flower buds will not have time to prepare for next year.
During periods of extreme heat, the bushes are not only watered, but also sprayed. This will help prevent the plant from overheating.
There is no need to feed blueberries. However, you can apply mineral fertilizers, especially if the soil is not nutritious enough. In spring, feed with nitrogen complexes - up to 90 g per plant. In this case, the norm is divided by 2 times. The first time they fertilize is in early May, then in the first ten days of June.
After this, until autumn, potassium fertilizers are applied at the rate of 100 g per bush. They are also divided into several times.
Loosening and mulching the soil
You need to loosen the soil around the bush a couple of times a season. Frequent loosening dries out the soil, which is unacceptable for blueberries. The root system will lack moisture.
It is important to remember that blueberry roots are located superficially, so careless loosening can injure them.The instrument is not buried more than 8 cm.
To ensure oxygen access to the roots, but to avoid frequent loosening, you need to mulch the soil surface with sawdust or other organic mulch. The layer needs to be updated several times a season. This will create the growing conditions necessary for highbush blueberries and reduce the number of waterings.
Trimming Features
Pruning for blueberries is very important. The shrub quickly ages and becomes overgrown with shoots, so you need to remove unnecessary shoots in a timely manner. In the spring, after the buds swell, cut out all disease-affected branches that are broken and thicken the bush. Last year's shoots are pruned just a little to stimulate growth. The bulk of the crop will develop on them. In summer, cut out all root shoots. In the fall, bushes older than 5 years are rejuvenated. To do this, leave 3-5 young shoots, and cut out the rest completely.
How to prepare highbush blueberries for winter
Many varieties of highbush blueberries overwinter well in open ground and do not require additional shelter. But young or recently planted plants need to be protected from upcoming frosts. To do this, they are well spudded and covered with spruce branches or a layer of dry foliage, and the soil is first mulched to a height of 12-15 cm.
