How to graft a lemon?
One of the most common and commonly consumed fruits is the lemon. Recently, gardeners have been interested in the possibility of growing a lemon tree at home. It turned out that not only in the southern latitudes with a favorable hot climate, but also throughout the country, such a citrus tree can be grown. The main thing is to graft the lemon correctly.
What is it for?
Gardeners have learned to grow lemons in their gardens. In order for a seedling to grow from an ordinary lemon seed, it is enough to plant it in the ground, water it and wait for the seedlings. After a certain period of time, they will appear, however, there is no guarantee that the shoots will be able to grow into a tree that will bear fruit. You can achieve the desired result only if you properly graft a lemon onto a branch of another tree.
The very process of grafting to a tree is a combination of two branches or the transfer of a lemon bud to the main trunk of a dominant plant. With such an implantation of a part of one plant in the branches of another, their fusion occurs. All processes for the exchange of mineral substances, oxygen are carried out simultaneously both in the scion and in the rootstock. The grafted branch becomes part of the tree and receives all the necessary components from the donor root system for life and further development in a new place. The grafted lemon branch bears fruit at the same time as the plant chosen as the basis for the graft.
There are several ways to carry out this procedure.
Timing
Lemon should be grafted in the spring, and can be until the end of summer.Any plants in the period from April to August release a large amount of juice, which contributes to the establishment of a new cutting on the main branch of the stock. Depending on the method chosen for grafting a lemon, the timing of the fusion of shoots (grafts) with the main trunk also changes. It usually takes a month for a grafted plant to gain a foothold and become part of it.
Rules
You can plant a lemon at home if you choose the right stock. Rootstock is a plant that shares many characteristics with lemon. This is a tree on which a lemon cutting is grafted. It is desirable that it also be a citrus plant or a tree belonging to the same family (rue).
For rootstock use the lemon itself, bigaradiya (sour orange), sweet orange, tangerine, grapefruit. These plants have a strong root system. This feature allows the scions to supply the grafted plants with nutrients. In grafts of this group, calluses (a kind of corns) quickly grow at the sites of tree injuries where the grafting was carried out. Calluses protect the painful places of the injured tree and promote their rapid healing.
It is best to choose dwarf trees for rootstock. Trees grow very actively, which causes certain difficulties in care. Dwarf stock can be made independently.
Cut off the bark at a short distance from the roots of the tree in a circle. The removed bark is fixed in place of the cut with the reverse side. After it is tied to a tree. This procedure significantly slows down the movement of sap along the branches and, accordingly, the growth of the tree cannot be intensive. To maintain the slow growth of the tree, this action should be repeated once every few years.The main rule for the success of the whole event is the presence of a fruitful scion.
If you graft a lemon onto a tree that is fruitless or bears little fruit, the grafted cutting is very likely to fail.
In order for the incision to heal quickly and efficiently, it is wrapped with a film of polyethylene or other material.
Training
When you have decided on the method that you will use in the process of grafting a lemon, you should take care of gardening tools. With their help, the scion is grafted to the main stock. The set of tools for work should contain:
- plastic tape or electrical tape in order to wrap the site of the entire operation;
- garden knife or blade;
- secateurs for trimming excess branches in the vaccination area;
- garden pitch, which will subsequently process the place where the bark is cut;
- stock as the basis for the scion;
- scion.
A lemon stalk for the grafting operation should be taken from a well-bearing tree. If you purchased twigs and could not plant them right away, then a refrigerator is suitable for storage for several days. The cuttings must be wrapped in a wet cloth and placed in polyethylene. Excess leaves are pre-cut. Leave only the buds and petioles from the leaves. In this way, they prepare them for further work.
Ways
There are several ways to graft a lemon at home to another plant. These include:
- budding and T-shaped budding;
- copulation and cleft grafting process;
- grafting with a cutting with or without secateurs.
One of the common ways to graft a lemon cutting to a rootstock is the usual budding. She is still in the butt shield.
The tree on which the lemon cutting will be grafted must be 3 years old. In order for the implantation operation to be successful, the main stem of the plant is chosen with a good sap flow cycle. This will contribute to the rapid separation of bark particles from the wood of the trunk and will allow work to be carried out with minimal damage to it. The process of budding is the transfer of a kidney from a lemon cutting into a depression on a branch of the main tree.
A lemon stalk with a bud on it is best placed in water to avoid drying out before you proceed to the very stage of budding.
The step by step process is as follows.
- First, a place is selected for grafting on the main trunk. It should be at least 10-15 cm from the ground. Next, a cross section of the bark is carried out with a garden knife. The length of the incision should not be large, within 1 cm.
- After that, an incision is made along the trunk. Perpendicular to the transverse incision, a cut of the bark is made at a height of 3 cm.
- With a knife, gently push apart the cut parts of the cortex, thereby preparing a hole for the implanted kidney (eye).
- A kidney from a lemon branch that needs to be grafted onto the base must be cut very carefully from the cutting. There are two methods for carrying out this procedure.
- In the first method, transverse incisions are made on the handle at the top and bottom under the kidney. With a knife blade from top to bottom, cut the kidney from the handle, slightly deepening the blade into it.
- If you are not sure that you yourself will be able to cut the kidney without damaging it, then it is better to use the second method. It's more simple. The stalk is cut into pieces, and the piece, where there is a kidney, is separated from the others. They hold it with the left hand, and with the right hand, in which there is a knife, they cut the kidney, deepening the blade of the knife into the bark of the cutting.In this way, a kidney is cut off and then inserted into a hole prepared in advance on the main trunk of the tree to which the graft is made.
- The inserted kidney is fixed on the trunk using polyethylene tape or electrical tape. It is necessary to fix the place of the cut with polyethylene in a circular motion from the lower point to its upper part.
- It is best to use a garden var to close the vaccination site.
- After 15-20 days, the petiole near the grafted kidney should fall off. This will indicate a successful vaccination.
- In a month, the kidney (eye) will sprout and a spike will form near it. Before a spike appears near the grafted bud, the stock is cut for the first time at a height of 10-15 cm above the site of the operation.
- After the appearance of the thorn, a secondary cut of the stock is carried out, but just above the thorn, and after that, the polyethylene is immediately removed, which closed the place of implantation of the kidney.
T-shaped budding is slightly different from the usual procedure. Not a kidney is inserted into the incision on the rootstock, but a piece of cutting with a kidney in the center. The procedure is performed in a similar way, only the incisions are made deeper and they also differ in length from the incisions for conventional budding.
- At a distance of 10-15 cm from the roots of the stock, an incision is made in the bark across the trunk. Then a longitudinal incision is made at a distance of 3-3.5 cm from the cross section. It turns out a kind of letter "T". With a knife, carefully move from side to side in the area of \u200b\u200bthe cuts to separate the wood and bark from each other.
- Next, a piece (shield) with a kidney in the middle part is cut off from the scion handle. You need to cut off the bark and some wood. With a knife, a transverse incision is made above the kidney on the handle and the same incision below it.The bark is removed, and then the knife is deepened into the wood across the rootstock trunk and, making a deepening, turn it to move along the handle. In this way, the cut is advanced to the kidney and, in place of the kidney, the knife blade is further deepened in order to cut the vessels and fibers that feed the kidney.
- After that, the knife blade is raised behind the kidney to the height of the transverse cut. A piece (shield) of the cutting cut in this way is inserted into the bark on the trunk of the tree to which the lemon is grafted. The kidney should be in the middle of the entire longitudinal incision.
- Then, the operation site is tied with polyethylene or tape, the kidney with a piece of leaf (petiole) is left uncovered. 30 days after the germination of the grafted particles, the bandage can be removed.
In order for the grafted lemon to bear fruit, the grafting method is also used.
In this case, you need a scion from a tree that gives a good harvest. The thickness of the bark and branches of the trees to be combined should be selected as close as possible to each other. Grafting is carried out in the rootstock trunk, splitting it.
- At the bottom of the rootstock tree, all leaves and growths are removed. A knife is inserted into this gap to a depth of 3.5 cm and the trunk is split in half. Get a split.
- Next, they take a scion with several buds on the handle, make oblique cuts in its lower part and insert it into the split made on the stock until it stops. The bark of the rootstock and scion should close together. This is a prerequisite for the final result.
- After the cutting is placed at the grafting site, this area is covered with a film or electrical tape. After a month, remove the bandage from the tree.
There is a lemon copulation method. In this case, the trunk of the main tree and the grafted cutting should be the same in thickness.
- Oblique cuts are made on the stock and scion. These sections should be long, larger in size than the diameter of the grafted cutting.
- The places where the cuts are made are interconnected. On the one hand, this is a stalk, on the other, the stem of the base tree.
- Kidneys should be present on the cutting. They remain undamaged. After the connection of the rootstock and scion is made, the grafted particle is fixed with polyethylene. The bandage must be applied carefully so that the sections do not move. An important point is the regular removal of extra branches on the rootstock in the area of the site of the operation. Otherwise, they will not allow the grafted cutting to grow and develop well.
There is also an improved way of copulation, with the so-called tongue.
Additionally, before combining the sections on the scion and stock, an incision is made that resembles a tongue. When oblique sections are combined, the tongues are also connected to each other. They must go to each other. After joining all the incisions, the operation site is tied. They wait a month and after this period the bandage is removed. As can be seen from the examples given, grafting a lemon at home is a feasible undertaking.
The main thing in this matter is to decide on the method of its implementation and do all the work at home carefully. After 2-3 years, you can harvest from a grafted lemon branch!
