Vaccination of plants is a delicate procedure with many nuances. This is especially true inoculation of different cultures, in particular, cherries and plums that are not very similar to it. Read about the features of the procedure and the best methods later in the article.

Is it possible to plant sweet cherry on a plum

It is better to plant sweet cherries on related cultures - cherries or cherries. However, a vaccine for plum or cherry plum is also possible and gives good results. In this case, survival rate is worse than that of related cultures, therefore, to obtain a satisfactory result, it is necessary to pay attention to all the subtleties of the procedure.

Did you know? Umeboshi plums, which have an unusual sour-salty taste for foreigners, are highly valued in Japan. One plum contains as much citric acid as several lemons.

Advantages and disadvantages of vaccinating cherries on a plum

• The vaccination of cherries on a plum has several advantages, in particular:
• improvement of juiciness and palatability of fruits after inoculation;
• fruiting is getting better;
• cultures exchange microelements, which enriches the fetus with nutrients;
• wood resistance to external influences increases.

The disadvantage of this method is not considered by agronomists to be the highest survival rate. The combination of cherries with other cherries or cherries is much more effective.

Optimal conditions for grafting sweet cherries

It is recommended to plant sweet cherries on plums in early spring . Since the two cultures do not show the best compatibility, the stalk may not have time to take root over the summer. Also, according to agronomists, it is important to consider the temperature and humidity of the environment. Environmental conditions also affect the amount of internal moisture of the plant: shoot moisture should be between 75–83%. At rates below 75%, the effectiveness of the procedure decreases, for this reason it is better to plant plants in warm, humid weather.

Hot arid conditions adversely affect the survival of the cuttings. Along with this, vaccination in the summer is not prohibited. In the southern regions, the procedure can be carried out until September.

Did you know? Plum is the main element of the breakfast of British Queen Elizabeth II. Every morning, the ruler eats 2 fresh plums.

Which rootstock is best used for vaccination

The success of the vaccination largely depends on the stock — the plant on which the graft is grafted. High-quality stock has the following qualities:

• age 3–10 years;
• maximum height 3 m;
• low growth rate;
• lack of damage, rot, breaks;
• the variety is zoned in the growing region;
• in varietal characteristics, fast survival of scions is indicated.

With the right choice of stock, the grafted variety is accepted in growth and after 5 years begins to bear fruit

What else will be needed for a successful vaccination

In order for the vaccine to be successful, you need to choose the right stalk. The graft material is cut from a healthy and stable fruiting cherry. It is best to choose stems not older than 1 year old, from the central tier. Good survival rate is shown by branches growing on the outer part of the bark from the south side.

Harvest cuttings 0.6–0.8 cm thick. Recommended graft length is 30–40 cm. In the upper part, there must be a whole growth bud and 3-4 leaf buds on the sides

It is also necessary to prepare materials for attaching the scion to the stock. Places of cuts cannot be left in the air - they must be covered with insulating material. As a mount fit:

• insulating tape;
• polyethylene film;
• rubber bands.

Important! Short branches with many flower buds are not suitable for vaccination.

Vaccinations in spring and summer

In the spring and summer season, the procedure can be carried out by the method of copulation, behind the bark, into a cleft, angular notch or lateral notch. Each of these methods has its own subtleties, which should be taken into account during the procedure.

Copulation

Copying is suitable when the rootstock and the scion stem are of the same diameter.

Follow the instructions below:

1. Cut at 20 ° on the scion and rootstock.
2. Make sure that the sections are even; if necessary, clean them.
3. Connect both parts with slices to each other.
4. Lock the connection.

Over bark

The optimal time for vaccination for bark is March and early April. At this time, the bark easily leaves the trunk, which simplifies the procedure.

We advise you to read about vaccinating cherries on cherries in spring and summer.

The vaccination technology for bark is as follows:

1. Make a scythe slice 3-4 cm long on the scion.
2. On the rootstock at the planned site of grafting, separate part of the bark according to the size of the cut on the handle.
3. Insert the grafted graft with a cut to the place with the cut bark on the stock.
4. Secure the connection with electrical tape or polyethylene.

Into the cleavage

Vaccination in the cleft is characterized by a high survival rate of the cuttings. Inoculation with such methods should be in early spring.

Perform the procedure as follows:

1. Cut a branch on a tree-rootstock, align the cut with a hacksaw.
2. Split the cropped shoot in the center. The depth of splitting depends on the diameter of the branch: thin stems are split with a knife 3-4 cm, large ones are split with a small ax 6-7 cm.
3. Grafted cuttings cut along the length of the recess in the stock. The tip should be wedge-shaped.
4. Place the scion with a cut in the cleavage.
5. Secure the vaccine with insulating material.

In the corner neckline

The grafting in the corner neckline is suitable for cuttings with a diameter of 2 cm and a thin bark.

When vaccinating with this method, proceed as follows:

1. On the hemp of the stock, cut a corner recess with a garden knife.
2. Trim the lower end of the handle to a wedge shape. The trimmed end should fit the corner cut on the stock.
3. Insert the stalk firmly into the corner cut on the rootstock.
4. Rewind the connection point with insulating material.

In lateral incision

The graft grafting method implies graft grafting on the side of the shoot.

When grafting a stalk, proceed according to the specified technology:

1. On a tree branch at a distance of 20 cm from the base, make an oblique incision in which one side is 0.9–1 cm larger than the other.
2. Cut the grafted graft so that on one side it has a wedge-shaped cut.
3. Insert the stalk into the cut.
4. Rewind the vaccination site to fix it with insulating material.

Further care

In the first year after vaccination, carry out preventive treatment of the tree from pests. Experienced gardeners are advised to use Biotlin or Tanrek. Branches growing near the site of inoculation should be removed - such stems take vegetable juices and prevent the graft from surviving. If the procedure was carried out in the spring, at the end of summer, the tops should be pinched.

Important! Do not forget about standard varietal standards for the care of plums. With proper watering and top dressing, grafting sweet cherry shows the best survival rate.

Sweet cherries will successfully take root on the sink, if you follow the deadlines and choose the appropriate method for the procedure. Given all these subtleties, the gardener will successfully cope with the task and after a while will receive a rich harvest of cherries.
