Features of the Selection of Microorganisms
The attractiveness of blackberry cultivation is a high and stable yield. The rich chemical composition of the fruits of the bush makes them especially significant for the human diet. This is a worthy alternative to garden raspberries and the opportunity to diversify culinary preparations. With proper planting and care, taking into account all the biological characteristics, the blackberry will bear fruit for at least 10 years.
The potential yield and benefits of blackberry fruits is much wider than that of its closest relative, raspberries. However, gardeners do not seek to plant and grow this magnificent shrub on their site.
This is due to the fact that for a long time cultivars of plants derived from southern forms were cultivated. They were difficult to take root in the planting region and led to mass disappointment of gardeners.
The situation changed after the emergence of new relatively winter-hardy varieties that are able to withstand lowering temperatures to -30 C.
Therefore, for cultivation in the middle lane or more northern regions (in Siberia and the Urals) it is important to purchase varieties of modern selection. Despite this, in the northern regions the cultivation of blackberries is somewhat limited. This is due to uneven fruiting, the final period of which often coincides with the first frosts and some of the fruits do not have time to ripen.
In addition, insufficient lighting leads to a loss of quality in ripened fruits.
Blackberry autumn planting has more advantages and is most optimal in the middle and southern regions. After planting the shrub, a period with a stable and cool temperature will follow, increased humidity will contribute to the development of roots, until the soil temperature drops to -4 ° C.
The blackberry leaves the state of relative dormancy very early and the bushes rooted in the fall will immediately begin to develop vegetative mass. During spring planting, the plant does not have time to take root because of too rapid warming and the beginning of sap flow, after which the active growth of shoots begins.
A weak root system is not able to provide the necessary nutrition, increasing vegetative mass. This greatly weakens the bush and affects the overall development.
Spring planting is preferred in the northern regions and if the blackberry variety is characterized by poor winter hardiness.
In autumn, the plant should be planted at least 20-30 days before the first frost, in the spring before buds open, when the air temperature rises to + 15 ° С.
For growing in a personal plot, planting material must be purchased in reputable nurseries. The best survival rates are distinguished by annual seedlings with two stems, the thickness of which is at least 0.5 cm in diameter.
