6 important works for the columnar apple tree

Waited! The peak of popularity of columnar apple trees is over. And all because the "happy owners" of these trees increasingly began to face unpleasant phenomena. Increasingly, the columns do not grow in the form of columns, but in the form of shaggy brooms, in addition, very strong. But the most annoying - columnar apple trees refuse to bear fruit.

Choose the right rootstock

Columnar apple trees will grow small and will bear fruit in the second or third year, only if they are grafted on a dwarf rootstock. Therefore, when buying a seedling, ask what rootstock it was grafted. The best rootstocks - M9, B9, P22 ...

If the column is grafted on a semi-dwarf rootstock or on a regular one, you will harvest the first crop only in the fifth or eighth year.

Vulnerable to frost

Columnar apple trees are more sensitive to frost than ordinary trees. Therefore, for the winter they must do moisture charging, and the trunk and part of the main branches wrapped in paper or cardboard. Ash or phosphorus-potassium fertilizers must be applied during excavation. The soil in the stump circles should be mulched with a 5-centimeter layer of humus or 10-15-centimeter layer of straw. In the spring, the shelter is scraped to the side to speed up the warming of the soil.

Damage to the apical kidney

The tops of the shoots ripen worse, and therefore usually freeze in winter. As a result, in the spring to touch not the top, but all the upper buds. If nothing is done, the tree will begin to resemble a broom. Therefore, leave one central shoot of the continuation, and the other cut. In June - July, pinch all the vigorous side shoots.

Misham - boycott

Mice can go around the base of the trunk, which is why the tree will die. Therefore establish around a trunk protection from a fine-mesh plastic grid. It works throughout the life of the tree. Wash the wounds with iron sulphate, smear with garden pitch and cover with plastic wrap.

Remove the apical flower bud

Some varieties of columnarists sin by laying flower buds on top of the conductor. And in addition to the escape grows two or four more fruits, which do not allow the central conductor to grow directly. To prevent them from deforming the central conductor, pluck the flowers and buds from the top of the central shoot.

Curvature of the trunk under the weight of the fruit

There are years when the fruit on the column is tied so much that the trunk bends. And it is fragile in columnarists and can break. To prevent this, remove some of the fruit or set a stake for each tree and tie it to it. K must withstand the weight of the fruit, and gusts of wind.
