Blackberries produce especially sweet and large berries in the sun.
Blackberries grow best in fertile, sometimes sandy, moist soils.
Organic and mineral fertilizers are applied to dug trenches up to 30 cm deep and 40 cm wide at the same rates as for raspberries.
Plantings are well watered at a rate of at least 5 liters per bush. In the future, young plantings are regularly watered at intervals of 7–10 days for 1–1.5 months.
Since the root system is shallow, blackberries are very sensitive to moisture.
Therefore, especially in the first years, this berry bush should be watered regularly.
You can water blackberries early in the morning or late in the evening: this way there is a greater chance that the moisture will reach the roots rather than evaporate from the surface of the soil under the hot rays of the sun.
In addition, water temperature for irrigation is from 23 to 25 ºC. The water must be settled.
Garden blackberries are not picky about soil quality.
Nevertheless, the maximum yield can be obtained on fertilized, well-drained loams with a neutral or slightly acidic reaction.
Calcareous soils are not suitable for growing, as the plant may develop chlorosis.
