They are tall crowns composed of a vertical guide, which is covered along its entire length with fruiting shoots. Vertical cords are best placed next to a wall with slats, hooks or wires, to which the guide can be tied (Lynx.).
Lynx. Pear trees in the form of vertical ropes against the wall.
During the formation period, a vertical stick is additionally attached to each tree and a guide is led along it.
Dwarf apple trees are planted along a wall or other scaffold to form ropes, the distance between the trees is from 0,7 do 1,0 m.
The planted maimers are attached vertically to the supports. Unbranched grafts should not be cut at all (Lynx.).
Lynx. Cutting trees and tying shoots in the first year of cord formation; unbranched oculants (two on the left) do not require cutting; in branched maiden trees, the upper ones are removed, strong shoots, and the lower one shortens.
Branched grafts must be trimmed as follows: two or three strongest branches are removed smoothly next to the guide. Shorten the remaining branches to 3-5 stitches. Shoots, that is, shoots to 20 We leave the cm of length uncut. The guide should not be shortened. Due to the relatively poor pruning of trees, they should be watered abundantly in May and June.. Please note, that the wall area is generally very hot and the trees may suffer from drought.
An important procedure in summer is removing the side shoots. Its purpose is to stimulate the growth of the conductor and create shoots on the vertical axis of the tree. The first pinching is done in mid-June when the shoots are approx 20 cm in length. We shape them over 3-5 fully developed leaves. Two weeks later we can find new shoots on the trees, which need to be removed again. Shoots pinched off in June give secondary growth, which we get in July over 1-2 a leaf (Lynx.).
Lynx. Summer pinching of shoots: a - the stronger shoots are pinched for the first time in June over 3-5 a leaf, Leave the shoots; b - after the appearance of secondary increments we pin them into 1-2 a leaf.
If the shoots were pinched regularly, it is possible not to cut trees in spring. However, it usually does, that one or the other side shoot, not torn off in time, grows to a length of 30-50 cm. If such shoots grow directly from the conductor, they have to be trimmed to 3-5 stitches in the spring. If they grow from a short shoot embedded on the conductor, you need to cut even shorter, that is, for 1-2 stitches.
In the summer of the second year after planting the trees, we perform similar procedures as in the first year. We lead the guide vertically along the pole, tying it two or three times (Lynx.).
Lynx. Cutting and tying shoots in the second year of formation of vertical cords.
This year's shoots growing directly from the guide should be pinched over 3-5 leaves in the summer. Shoots emerging from twigs should be pinched out shorter, that is, on the 2nd or 3rd list. Leave the 5-10 cm long shoots uncut.
In the third and fourth year, we continue the treatments as in the second year. These include tying the guide, summer pinching of vigorously growing shoots supplemented with spring pruning. The cords are usually led to a height of approx 3 m. When the trees reach this height, the guide is removed. After shaping is completed, annual cut into short shoots is required. Cutting performed in summer gives the best results, once at the beginning of August. At this time, cut out all the stronger growths above the 2-3 leaves, leaving only those, which they have to 20 cm in length. Instead of a summer cut, you can make a spring cut, shortening strong shoots to 2-3 eyes.
Several-year-old trees are covered from top to bottom with fruiting branches, which, despite the annual cut, are slowly growing. Excessively overgrown twigs must be shortened from time to time, that the total diameter of the cord does not exceed approximately 0,5 m. You can cut over any shoot at a distance of approx 20 cm from the guide.
