The Altruistka variety is a type of cherry and sour cherry, the quality of which largely depends on weather conditions and proper care. To achieve high fruit quality, sufficient moisture during the growing season is essential, as dry conditions reduce sugar, vitamin C, and organic acid content in the fruit. Optimal yields are achieved with a hydrothermal coefficient (HTC) ranging from 1 to 1.4, reflecting the ratio of precipitation to the sum of daily average temperatures above +10 °C.
For successful cultivation of the Altruistka variety, it is necessary to carefully select the planting site. The best locations are plains with fertile soils and good natural drainage. In northern regions, gentle southern and southwestern slopes are preferred, while in southern regions, northern and northwestern slopes protected from dry winds are ideal. It is important that the groundwater level is at least 1.5–2 meters deep for cherries and 2.5–3 meters deep for sour cherries, and avoid planting in low-lying areas or locations where cold air stagnates, which can lead to frost damage of flower buds and reduced fruit set.
Soils for the Altruistka variety should have a light mechanical composition to ensure good aeration and drainage. Proper care, including timely planting, pruning, fertilization, and protection from pests and diseases, will contribute to a bountiful and high-quality harvest. Adhering to these agronomic recommendations will allow you to grow delicious and nutritious fruits that will become an excellent addition to the family’s diet.
