Vertical rope of grapevines.
This form is suitable for vines planted against walls and fences. The vertical cord consists of a vertical height guide 1,5 m and very short skeletal shoots called knots embedded on it. New shoots grow from these knots every year, which are subjected to summer pruning during the growing season, and after fruiting, they are cut very shortly into a suppository. Two shoots are made from each knot (Lynx.).
Lynx. The grapevine is stretched on the wall in the form of vertical ropes.
We start forming the vertical cord in the third year after planting the vines. In the spring, we cut the bed over 3 eyelet, at a height of approx 30 cm from the ground. Attach the shoot growing out of the uppermost mesh vertically, and the rest 2 Unbutton the shoots diagonally (Lynx.).
Fig. Vines trimmed in the first year of forming the vertical cord.
The shoots must be bent very carefully because they are brittle. When the plants have faded, pin the side shoots on the 3-4th leaf, by deducting them from the second group (Lynx.).
Lynx. Vertical cord in summer after the first cut; a conductor tied vertically, side shoots tied obliquely and trimmed on 4 leaves above the second cluster.
We let the guide grow higher and only at the end of the summer we remove the top of it. After the first summer pruning, stepchildren will grow up, which need to be pruned over the second leaf (Lynx.).
Lynx. Second summer cut; cut the stepchildren above the second leaf
These activities should be done early and repeated as new stepchildren appear. In autumn, to make it easier to cover the bushes for the winter, we prune all shoots on 4 fully developed meshes. After discovering the bushes in the spring, we shorten the shoots even more, side on 2 well-formed eyes, and the peak or guide on 3 mesh. They will grow out of the left side eyelets 2 fruiting shoots, of which the upper shoot is called replacement. In the following year, the lower shoot will again be trimmed to 2 mesh, and the surrogate momentum will be completely removed.
We perform summer cutting in the same way as last year, trimming shoots on 4 a leaf above the second cluster and pinching the stepchildren (Lynx.).
Lynx. Vertical cord in the summer of the second year after cutting; shoots trimmed to 3-4 leaves above the second cluster.
In addition to the two shoots developing from the two fully developed eyes, additional shoots may also develop, from poorly educated meshes. These shoots should be removed as soon as possible.
Peak momentum, which we trimmed in spring on 3 meshes will give us a guide extension in summer and two side shoots, which we will turn into knots the next year.
In the following years, we perform cutting in the same way as in the second and third years,.every year to receive po 2 new side shoots and an extension of the conductor. After the string is led out to the height 1,5 m, we cut the peak momentum at 2 mesh, and the shoots grown out of it are treated in the same way as side shoots.
After molding is complete, two methods of cutting the skid can be used. Short cut and long cut. Short cutting consists in shortening the skids in spring 2 fully developed meshes, of which two fruit-bearing shoots develop in summer. Low-growing varieties such as Chrupka Złota, Pink crisp, Portuguese Early – require a short cut. Strongly growing varieties like Perła Czabańska, Aurora – require a long cut. When using a long cut, we shorten the bed in spring 6-9 eyelets and lead as many shoots. In addition to the spring cutting skids, Summer cutting plays a very important role. In May, after the buds develop, redundant shoots need to be cut, which appear on the stump or b of the skid base, from sleeping eyes. We only leave these shoots, which grew out of fully developed meshes.
During flowering, pinch the fruiting shoots, leaving 3-4 leaves above the upper cluster. Premature shoots, i.e. stepchildren, need to be removed as soon as possible and the removal should be repeated many times during the summer, as they come out.
