VACCINATION OF GLASSES AND FORMING THE CROWNS
In the third year, only a small amount of dwarf rootstocks for inserts and apple tree varieties may remain in the plots only in a small amount., grusz, and sometimes cherries. Which, lantas of dwarf washers, which have not been budded or whose eyes have died during the winter, should be vaccinated a second time in spring. One shoot always emerges from the accepted scions.
In order to obtain 2-year-old trees with a properly built crown, the main shoot of maiden trees should be trimmed (cut).
The height of trunks of trees produced in Poland is regulated by nursery regulations. The highest permitted height of the trunk may be 100 cm. Such trees are called half-stem trees. The height of the trunk of low-growing trees is 31-60 cm, and bush trees 30 cm. If the trees are to have a trunk high 80 cm, this after adding a section of the shoot of length 20-30 cm to create a crown, the guide should be shortened to the height 100-110 cm. Side shoots in branched maiden trees are shortened to 3-4 mesh. It is recommended to cut out thicker shoots for a wedding ring.
At the end of August, shoots growing below the crown must be cut. For this purpose it is chosen 4-6 shoots together with the guide for the formation of the crown, and the rest are cut into a wedding ring.
The shoots at the crown should form a wide angle with the guide.
After the trees are pruned, the plots should be sprayed against diseases that cause gangrene of the bark. It is best to use Topsin M in a concentration 0,1%.
