Growing and care
Alvar's potatoes can be grown in different ways, but the classic scheme is more often used. Before carrying out the procedure, it is necessary to properly prepare the soil, namely to free it from weeds, plow and fertilize.
Seed material is selected and germinated, then the germination of Alvara increases.To make the sprouts larger, they are laid out in a room with a temperature of 22 ° C, from time to time they are moistened from a spray bottle.
Alvara is laid out in the ground when the temperature reaches + 8 ° C. It is advised to water the area where the subsequent planting is expected in a few days.
Ash or humus can be used as a top dressing for this variety of potatoes. The distance between the rows when planting is at least 50 cm, the immersion depth of the planting material depends on the region and climatic features. Usually at least 8 cm. Every 3-4 years it is recommended for Alvara to change the site.
Watering is carried out twice a week, weeding is carried out as needed. In the Northern regions, Alvar is recommended to huddle to protect young plants from frost.
During the growth process, the potatoes are fertilized several more times. The first time feeding will be required when the tops begin to grow. Ideal for this variety is urea, bird droppings or mullein.
Wood ash and potassium sulfate are used during the budding period. The third time Alvara is fertilized when flowers appear on the bushes, it is best to use nitrophosphate during this period.
