Reproduction of grapes by cuttings: harvesting cuttings

Harvesting grape cuttings

Any summer resident dreams of owning grapes. For this, you can buy rooted cuttings or prepare the vine and grow seedlings. The acquired grape seedlings may not be adapted to your climatic region, and your works will be in vain. The best option is to take grape cuttings of the type you like in your area.

Reproduction of grapes by cuttings is not very difficult, but this requires patience and desire. Cuttings can be harvested in autumn - after falling off the leaf, but before the onset of the first frosts (November), in winter (late February), and in the spring (before the bud budlaps).

How to propagate grapes with cuttings? Easy enough. Cuttings have the ability to quickly root, and the seedlings grown from them retain almost all the varietal properties and signs of the mother bush in an unchanged form.

If cuttings harvested from the fall, this should be done at the time of pruning shrubs. The reason is simple - sheltered by the ground cuttings will lose some of the eyes when frozen and discolored. And the autumn harvesting of cuttings gives a high percentage of developed eyes in comparison with spring. If you have the opportunity to store cuttings of grapes at a constant low temperature of up to 0 ° C, cuttings should preferably be harvested in autumn, when the grapevine contains the largest amount of starch.

Reproduction of grapes by cuttings harvested In winter, has its disadvantages: the first - in the vine there is a lack of carbohydrates, the second - you do not know the state of the vine, which could be damaged by frost, which often leads to the development of gray rot.

Cuttings harvested in spring when pruning a vineyard have their advantages - the results of wintering of the vine are known, frozen or dead areas are visible. This makes it possible to choose strong cuttings, in which frosts do not damage the eyes. Harvesting cuttings in the spring has its own characteristics - do not use a vine, which was under snow all winter - it can be damaged by a fungus (spotted necrosis).

Harvesting cuttings of grapes is made from shrubs that have better yield and growth rates. To do this, choose a well-ripened vine, not damaged by disease. If cuttings are taken from a poorly ripened or sick vine, the propagation of grapes cuttings will be Is due to the inadequate content of nutrients for rooting, which can result in weak bushes.

Use for the preparation of cuttings middle and lower part of the vine or stepchildren, but in no case are the tips of the shoots. Experienced specialists try to take shoots that developed on the vine from the central kidneys in the previous year. Cuttings are selected with 3-4 eyes with a diameter of at least 8 mm (and thicker). Thinner cuttings are undesirable - they give a small yield of standard seedlings.

Determine the degree of maturation of the vines can be visually - the ripened vine has a characteristic yellow or brown-brown color of internodes and nodes. In this case, the internodes themselves are of average size, the core is 30% of the diameter of the shoot, and the stem, when bent, produces a slight crackle.

Preparation of cuttings in the autumn is made on the day of cutting the vine - you can not allow them to dry out or freeze, which will significantly affect the propagation of grapes cuttings. The workpiece consists in the following: the cutter cuts the cutting in the lower part of the vine under the knot, leaving a stump about 4-5 cm. The upper cut of the cut is made at the center of the interstice. The required length of the cuttings is 60-80 cm. This is 20-25 cm longer than the planned depth of disembarkation, but before planting it is possible to update the dried sections of storage when storing.

Reproduction of grapes by cuttings in autumn requires Cleaning of the material from the antennae and stepsons. Cuttings tie with wire (unwanted wire). You can harvest fragments and longer lengths - they are better preserved, and from them you can make additional cuttings. Store the material in winter in a trench, sprinkled with earth, or in a cool, dry basement with ventilation.

Before stacking, cuttings should be protected from mold growth - they are immersed in a five percent solution of ferrous sulfate for several seconds.
