Subtleties of apricot grafting
Apricot is very popular among Russian gardeners. This culture has undeniable advantages, among which one can single out high fruitfulness, resistance to diseases, ease of cultivation, pleasant fruit taste, etc. The peculiarities of this plant also include the fact that it can be given interspecific vaccinations. The procedure is quite simple, you just need to familiarize yourself with the basic rules for vaccinations so that the plant grows, develops and bears fruit better.
Why is it needed?
Grafting is a technical way of connecting one plant to another, with the help of which the quality of the crop can be improved. The attached part is called scion. As a result, such a shoot takes root on a tree and receives all the nutrients from it. In the future, culture develops as a whole, its characteristics improve. The success of the procedure depends entirely on compliance with the rules and the sequence of their implementation.
Until recently, ready-made seedlings were used for tree propagation, which were separately bred and grown. Such seedlings were obtained when cutting good trees, which brought large fruits in large quantities.
But then, instead of planting such seedlings in open ground, they began to be grafted onto other plants so that they would receive nutrition not from the earth, but from the root system of the tree. Such sprouts are no longer afraid of drought or frost. It also allows you to get a high-quality and stable crop.The common root system makes it possible for the grafts to quickly grow together and produce a crop in 3 years.
With the help of vaccination, the level of frost resistance of the crop can increase, which is especially important for the northern regions of the country. In this case, two plants are crossed, one of which is not afraid of severe frosts.
Experienced gardeners say that grafting allows you to get unique fruits with great taste. In this case, it is not necessary to cross the same types of trees. For example, a pear can be crossed with quince, cherry or sweet cherry. The same can be done with apricots.
What are they vaccinated for?
Apricots can be grafted onto plums, thorns, cherries and other stone fruits. Plum rootstock is chosen quite often. Cultures are well combined, which ensures high survival rate. The frost resistance of the plum is transferred to the apricot, which makes it more hardy.
Blackthorn is able to adapt to various climatic conditions. He is also unpretentious to the soil. The disadvantage of such an alliance can be called the rapid formation of root shoots. This slows down fresh sprouts and affects fruit availability. It is not recommended to use a wild turn for this event. The best option would be grafting with prunes, but even here the option of the appearance of shoots on a tree is not ruled out.
Cherry stock is rare. This is due to a number of reasons. Cultures are not very suitable for each other, especially for some varieties. In addition, the fragility of the obtained branches requires their additional strengthening. Otherwise, grafting can cause breakage of branches during a bountiful harvest.
Some gardeners graft an apricot onto a cherry plum. This is a good way to get a large fruit harvest in a short time after grafting.As a result of the procedure, the apricot receives unpretentiousness and frost resistance. Cherry plum takes root well and bears excellent fruit. Apricots may have a sweetish aftertaste.
Peach goes well with apricot, but such vaccinations should only be done in warm regions. This is due to the fact that the culture does not tolerate frost well. As a result, the whole tree may die.
Grafting an apricot to an apricot is the best solution. Often different varieties interbreed. But the maximum result can be obtained from combining the same varieties. This will help speed up the harvest for several years. A grafted cutting will bear fruit in 2–3 years, while a new seedling will develop in about 4–5 years.
But it is worth refusing to graft an apricot on an apple tree. There will be no positive result with a pear either. The fact is that the plants are absolutely incompatible.
Timing
This procedure is done in spring and summer, when the kidneys swell and sap flow along the trunk begins. Although the best time for grafting an apricot is still considered the beginning of spring. The specific date depends on the climate of the growing region.
Often practiced and summer inoculation culture (July-August). Readiness is determined by how the bark separates from the wood when notched. In summer, fresh green cuttings serve as a scion, which is a big plus. It is desirable that during the procedure the weather was dry.
Vaccinations are rarely done in autumn, usually only in the southern regions. Work can be carried out only before the onset of frost. At the same time, experienced gardeners protect the grafting site with packing paper, sawdust and polyethylene.
Some specialists also do winter vaccinations, which are usually carried out indoors on small trees.When the temperature outside rises above 2 degrees Celsius, such seedlings can be taken out into the garden and dug in with earth.
It is worth remembering that during the vaccination period, the apricot becomes weaker, so it is necessary to carefully process the cut points and take care of them until the juices go down the trunk.
Also at this time, you need to increase the watering of the tree and regularly apply mineral fertilizers.
Rules
Apricots should only be crossed with stone fruit trees. An equally important factor is the compatibility of different varieties with each other. Here it is important to take into account their individual characteristics, for example, age or size. The timing of the event and the weather also matter. It is also worth remembering that grafting is done on trees that are no more than 10 years old, as they have elastic tissues. To maximize the result, it is recommended to vaccinate on different parts of the tree.
It is important to follow the rules for preparing the scion. For grafting, rods with a diameter of at least 5 mm are prepared, on which there are kidneys. The optimal length is 15 cm. It is important to pay attention to whether there are any cracks on them. It is ideal to use not too thin branches that are not damaged by fungi and other diseases. It is better to take cuttings from a young tree that gives a rich harvest of fruits. The outer part of the crown, well illuminated by sunlight, is preferred.
Material for spring vaccination is harvested in late autumn. In this case, the temperature should not be less than -10C. The resulting cuttings are tied in bunches and left until grafting.
To save branches until the day of the event, you can use one of several methods:
- place them in a box filled with sawdust, wet sand or peat, and leave them in the basement, where it is damp and cool (the contents of the boxes must be regularly moistened);
- wrap them with a damp cloth and polyethylene, placing them in the refrigerator;
- wrap with polyethylene and store in the snow on the street (the snowdrift must be at least 50 cm).
The main task of such storage is to ensure the rest of the cuttings until the vaccination itself. This will keep them fresh and improve their survival rate. The night before the procedure, it is recommended to soak the cuttings in water. This will saturate them with moisture and allow them to hold out until the moment when the stock begins to provide nutrients.
Some gardeners ignore the preliminary preparation of the material, preferring to cut it in the spring just before grafting. But in this case, they run the risk of getting branches frozen over the winter period, which simply will not take root.
Summer vaccination, on the contrary, is carried out with fresh cuttings, cut shortly before the event. After cutting the cuttings, it is important to prevent their rapid vegetation, and therefore the scion is wrapped in a damp cloth after cutting and kept at a minimum temperature of 3-4 days.
If you want to keep the material for a longer period, you should also wrap it with a damp cloth. In this case, the cuttings are also stored in polyethylene in a cool place. This will increase the survival of branches up to 2 weeks, but may reduce their survival rate.
It is better to cut the material in the morning, before the onset of heat. Harvest it in rainy weather is not worth it.
It should be remembered that all leaves must be immediately removed from the cut branch so that moisture does not evaporate through them.
Also, immediately before vaccination, it is necessary to check the quality of the scion.To do this, an incision is made on it, the color of the vessels is determined. If it differs from the natural one, then such a cutting is no longer suitable for grafting.
Among other things, it is important to choose the right time for vaccination. It should not be too hot, but dry weather, when there is no sun in the sky, but rains are not expected soon. Pre-prepared cuttings should be stored in natural conditions, where they are provided with a sufficient amount of moisture.
As already mentioned, it is better to vaccinate in the spring, when after winter the juice begins to circulate through the tree. This increases the chances of getting a good harvest and fast splicing of the scion. Experts advise doing such a procedure in early May, of course, if it is already warm outside at that time.
Some types of apricot can be grafted in the hot season, while they feel good. A feature of the summer vaccination is that it quickly takes root and shoots in the second year. But here it is important to study the growing conditions of the tree, determine its age, and also choose the right graft and cutting so that they quickly grow together and fit perfectly together. In the event that the summer vaccination fails, it can be repeated in the fall or spring.
Before the autumn procedure, it is especially important to follow the weather forecasts. If the temperature drops too soon, the cuttings will quickly be damaged, and the procedure will not bring the desired result. It is also worth refusing to graft the apricot at the time of high humidity, which can adversely affect the survival rate of the parts.
Ways
Novice specialists rarely think about the methodology of this action, therefore, they carry out all operations using the “scientific poke” method.However, gardeners with experience know how to graft correctly. Currently, there are many options for vaccinations.
Among them, two main ones can be noted.
- In a split. In this case, an incision is made on the branch, a stalk enters its center, which should be freely placed there.
- Copulation. The procedure is similar, only the stalk is fixed on the tree quite firmly so that they become one.
It is worth considering that the older the tree, the more difficult the process of tissue germination. To hold an event in any of the ways, you need to prepare a knife with a clean blade.
Experts note that for the procedure, you need to take only disinfected tools so as not to bring infection into the tree.
Step by step master class
All vaccination options are produced in almost the same way, differing only in some points. Each of the methods has its own advantages and disadvantages, which only experienced gardeners are familiar with. The option must be chosen, taking into account which trees interbreed with each other, what is their age, what are the climate features in the growing area, etc.
The step by step process looks like this:
- on the branch to which the seedling is to be grafted, an incision is made up to 3 cm long;
- a stalk is inserted into it and fixed with electrical tape;
- the vaccination site is treated with a garden pitch so that the infection does not penetrate there (if it is not there, you can use a special oil-based paint).
It is important to tie the grafting site tightly to prevent wind from moving the branches. Only a tight fit can ensure good survival. During the entire period of growth, the bandage should not be removed.The fact is that it not only ensures the density of pressing different branches to each other, but also contributes to a better interaction of plants. As a result, the exchange of nutrients between them improves and the flow of water into the tree crown increases. If everything is done as described above, then there is a 98% chance that the stalk will successfully take root and will bear fruit in a year or two.
Further care
With experience and sufficient skills, the whole procedure takes about 10 minutes. A positive result will be the appearance of leaves on the handle. This usually happens in the second or third year. There are times when leaves appear the following year.
After the graft grows together, it is important to provide the tree with the necessary care that will help it prepare for wintering and get stronger.
To do this, you need to follow a few rules.
- Young shoots are cut below the grafting site.
- If there is little rainfall in the area, you need to regularly water the tree and fertilize it.
- It is necessary to periodically spray the plant from pests and diseases.
- In the spring, a cutting is formed so that it grows in the right direction.
It is necessary to follow all these rules, since the tree can reject the stalk.
It is also important to remove the shoots on the shoots in time, which will enable the cutting to get stronger and ensure that it receives nutrients from the tree.
Conclusion
From the foregoing, we can conclude that it is possible to graft and grow an apricot even in the most difficult climatic conditions. The main thing is to use a good stock for this. If there are trees on the site that bear tasteless fruits, but are adapted to environmental conditions, you should not rush to get rid of them.To do this, it will be enough to plant new types of trees on them, which will enrich the crown and improve the quality of the fruit. At the same time, the root system, adapted to the growing conditions, will save you from problems with the survival of new branches and their nutrition.
If you need to grow a frost-resistant apricot on a plot, it will be enough to plant a cutting of a tree growing in the northern regions of the country on it. In this case, you will not only be able to get delicious fruits, but you will also harvest several times a year, depending on temperature conditions. Such a tree and stalk will not “go to bed” early in the autumn, and will also “wake up” in the spring immediately after the snow melts, which will ensure the duration of their activity and fruiting in the season.
