Blueberries are a very valuable berry in terms of their chemical composition; therefore, in recent years they have begun to actively grow it in our gardens. Pruning blueberries of tall varieties requires minimal knowledge. However, caring for the plant will bear fruit.
Blueberries - Blueberries
A variety of varietal species of garden blueberries are bred from wild shrubs of the genus vaccinium of the heather family. Blueberries are often identified with blueberries. The difference between them is really very small. Blueberries, unlike garden blueberries, do not leave stains that are difficult to remove on clothing or on the skin. Blueberry shoots differ from blueberry. Their difference lies in the fact that they are lignified to the very tips. At the same time, imported blueberry garden saplings are often sold here under the name blueberries.
The most common varieties of garden blueberries in our country are Berkeley, Blucrop (the main species in terms of prevalence in our latitudes), Erlblu, Spartan and a few others. Recently, a variety of blueberry garden Bonus has been appearing on sale in garden centers more and more often. At the same time, all these varieties appear under the name garden blueberries.
Selection of garden species from wild bushes began in the last century in North America. Due to the complexity of propagation and its high cost, undersized blueberry shrubs are grown and sold in very small quantities.
The tall shrubs mentioned above are derived from the genetic material of shrubs growing in Canada and the northern United States. These newly bred species are resistant to winter cold, various diseases and late ripening of berries. Although undersized shrubs of blueberries - blueberries have better properties than tall ones. This is especially true for the properties of berries. So, the fruits of undersized bushes contain much more pectins that are very beneficial for the body. Along with this, the fruits of small bushes have a more pleasant and rich taste. However, the fruits on low bushes are much smaller and less abundant than on tall ones.
Blueberries: pruning methods
How to Prune Tall Blueberry Shrubs
Trimming blueberries of tall varieties is necessary at a reasonable minimum. Based on the foregoing, this process is not so laborious.
Blueberries, which loves acidic soils, can grow up to 3 meters high in correctly selected areas. But usually it is a shrub 1.2 - 2 meters high.
Fruiting are usually not central, but lateral shoots. In this case, flower buds are formed on the shoots of the second year of growth.
In video 1, you can see how to identify the shoots to be trimmed.
The main pruning of tall blueberry varieties is to remove damaged or obsolete twigs and blind growth. The blind are called shoots that do not give flower buds. Most often this comes from a lack of sunlight due to thickening of the bush. Although blueberries can not be attributed to photophilous plants, but it also requires sunlight to actively plant flower buds. If the bush of blueberries is sufficiently well lit, then on young shoots of the second year of growth, up to 8 berries can form from one flower bud.
You should also remove the branches that lowered down to the ground, as well as those that gave a lot of side shoots. Such highly branched shoots will also thicken the bush greatly.
Young bushes require only formative pruning. The bush should be shaped so that it is erect, but at the same time slightly spreading so that the light penetrates in sufficient quantities to all branches of the plant.
Anti-aging pruning is performed on plants older than 7-8 years. They should be removed annually up to 20% of the old branches to give the opportunity to develop new shoots.
Bushes require full pruning berries on which they were chopped heavily, or if the bush looks tired and gives a weak growth. In this case, anti-aging pruning is performed. Trim branches for young growth, and some completely delete. Such pruning can be done both in early spring, until the bush has started to grow, and in winter.

Proper and timely pruning of tall shrubs can be a good contribution to further improving plant yields and improving the quality of berries grown.
