Introduction.
If you are interested in whether it is possible to graft cuttings of a particular variety on an old bush of ordinary grapes, then we can say with confidence that yes, you can. Moreover, you will be able to get several results:
- The taste of the berries will improve.
- The timing of harvesting will be significantly reduced.
- A varietal plant will improve its resistance to disease.
It will also be interesting that several varieties can be grafted onto 1 old bush at once. grapes... Grafting grapes is a fun and rewarding process. There are several methods of vaccination. Let's consider them in more detail.
Grafting grapes in the spring.
At the end of the autumn period, you can try to graft the cuttings of a young plant into the green shoot of an old one. This method is most often resorted to by those summer residents who grow grapes who could not prepare cuttings in time. You can also use the "green to green" method when, suppose, your neighbors in a summer cottage gave you a young stalk of a delicious berry.
Despite the fact that many people choose this method for its simplicity, it is still important to keep in mind several nuances that will allow the grafting procedure to be carried out correctly and without negative consequences. It is important to observe the conditions of a particular season - the end of May is best for grafting. This is due to the fact that the flow of sap begins and the vines grow intensively. That bush, which will act as a rootstock, will need to be cut during the dormant period (early spring or autumn). The cut must be done approximately 5 cm below the ground level, after which it is necessary to process it with a garden varnish solution.
The shoot that has already been prepared must be carefully shed and covered with straw. You can also stretch a film on top, which will help the soil to warm up faster and the shoots will begin to grow faster.
When the shoot reaches a length of about 25 cm and they are strong and ready to begin to grow stiff, this will mean that the bush is completely ready for grafting.
What to do when applying the green to green method.
On the side of the vine, you must leave 2 shoots, which are the strongest. The rest of the shoots need to be removed. Those that remain will be important to shorten with a sharp knife. A straight cut must be made under the second knot. The leaf that grows above the first node can be left. But keep in mind, if you notice the appearance of a stepson on it, then it needs to be carefully removed. The presence of 1 eye will be enough for the graft. Therefore, the green stalk needs to be cut into short pieces.
Above the sheet, it is necessary to leave about 1.5 cm in length, under the sheet - about 2 cm. The sheet is cut approximately in half. The next cut of the scion must be made in the form of a wedge. The operation is carried out exclusively from the lower side. This is very important in order for the rootstock to enter the split tightly. The final point of the process is to isolate the live cut site. It must be wrapped with film, covered with garden var, and placed in a plastic bottle. Until a new branch begins to grow, it is not recommended to remove this bottle.
Grafting with a one-eyed cutting into a green shoot.
Grafting in the summer is possible using a matured one-eyed stalk. If you do it right, you can start harvesting even earlier than if you use the green-to-green method. The only difference is that the harvesting of the scion must be done in the fall. In springtime, it is necessary to inspect the cuttings, choose the strongest ones and place them in water, to which you need to add the root.
After 2 days of such soaking have passed, the material must be dried and cut into pieces so that each has 1 eye. The edges of the sections must be treated with warm paraffin. Cut cuttings, which have been treated with paraffin, must be stored until the beginning of the summer period, keeping the temperature +4 +6 degrees.
Best of all, the grafting material must be placed in different bags and signed on each with the name of the variety used. in mid-June, the stalk must be taken out of storage. The lower part of the cutting must be cut in the form of a wedge, then inserted into the cleft of the young shoot. The actions performed are identical to those of the green-to-green method.
Rules for the care of grapes.
After all the actions have been performed, it remains only to wait for the results to appear. If you want to help a new variety take root in a new place, you need to provide proper care and attention to the grapes.
To do everything right, you need to know a few nuances:
It is necessary to very clearly carry out all the actions that are associated with the grafting process. After all, like any other process, it is very important to comply with the conditions, the grafting time, how it is necessary to harvest the material, how to prepare the stock. If at least one condition is not done correctly, then the result will definitely not be positive.
Also, the correct winding of the cut-off point is very important - tight and sealed. If you notice that juice begins to appear from under the processing area, it means that you have done something + wrong. The plant may begin to lose its energy, so this will adversely affect the life of the plant. Be sure to make sure that there is no extra growth point on the shoot. The plant should focus on the growth of the newly grafted cuttings.
If you planted grapes in a place where there is a lot of sun and fertile soil, then this is especially important. Therefore, in this case, you will need to constantly process the stepsons. Also, the production of care for the main plant is also very important. The plant definitely needs sufficient watering, as well as a sufficient amount of sunlight. It is important to monitor the temperature. If it is cool in summer, the scion may not develop.
It is important to remove any weeds that may appear around grapesso that the soil is sufficiently loose between waterings. It is important to ensure that the plant does not get sick during this period and does not undergo fungal infections.
Correct grafting of grapes.
In addition to strict adherence to all actions related to the grafting process, it is necessary to carry out the procedure itself on a warm and sunny day, when the air humidity is high enough. If you choose a day that is too hot, the cut may dry out. If you do not want this to happen, you need to wrap the cut place with a damp cloth under the film.
It is very important to ensure that condensation does not form under the film during the entire summer period. If you notice that there is no condensation, then this may mean that the fabric has simply dried up and you need to make it wet again. After you notice that new and strong shoots have appeared, only then is it allowed to remove the film.These simple rules will help you carry out the grafting procedure in both spring and summer. Also, some summer residents carry out vaccinations in the autumn.
