How to graft tree stump rose

Rose is a kind of tufted shrub with no obvious trunk, and in order to cultivate rose bonsai with stump characteristics, it is often necessary to adopt grafting means. The stump that can be used for grafting rose mostly uses rose as rootstock, at the same time, rootstock is required to grow healthily, root system is developed and there are no diseases and insect pests. The tree stump rose cultivated on this basis is often more ornamental after it is made into bonsai.

And if rose stump is used as rootstock to graft rose, many varieties of rose can be grafted on the same old pile at the same time, making rose bonsai blossom larger, more colorful, branches and leaves more luxuriant, and florescence longer, so it is more durable than ordinary rose bonsai, both ornamental value and economic benefits are often higher. So, how to graft the tree stump rose?

First, select rootstocks

Making stump bonsai by grafting is first of all very important to the selection of rootstocks. Because the stump rose bonsai requires well-developed root system, stout trunk, round crown, numerous branches and colorful flowers, and the sturdy rootstock should not only be able to support the whole crown, but also have sufficient ability to supply nutrients, which is the key to the success of grafting. At present, the most suitable and widely used rootstock is the old pile of Rosa, and the American thornless rose and Japanese thornless rose are the two most widely used rootstocks.

Second, make scion

In order to cultivate high-quality stump rose bonsai by grafting, we should not only choose a good rootstock, but also require us to produce a high-quality scion. In order to produce high-quality scions, it is often necessary to meet two conditions: one is that the scion varieties have strong growth advantages and the ability to germinate branches in order to form a round crown in the later stage; the other condition is that the characteristics of the scion should be as close as possible to the selected rootstock, which can not only inherit the advantages, but also more conducive to the survival of grafting.

III. Timing of grafting

The grafting time of tree stump rose is often determined according to the temperature environment, grafting materials and grafting methods, especially the original is greatly affected by the temperature environment. Due to the vast territory of our country, the temperature difference between the north and the south varies greatly, usually the four seasons are not very obvious in the south, while the four seasons are often distinct in the north, so the temperature environment varies with different regions. However, the grafting process often requires the local temperature to be suitable and stable, so it is necessary to choose an appropriate time for grafting, especially to avoid grafting when the temperature fluctuates too much in a short period of time. It is generally suitable for spring grafting in the south of China and autumn grafting in the north of China. But it still has to be considered according to the local situation.

IV. Preparation for grafting

In addition to grafting, we must make preparations in advance, especially all possible tools, such as paper cutters, special branch scissors, grafting knives, grafting belts, and so on. The grafting work generally needs to be carried out when the nutrient accumulation of the rootstock and scion is the most abundant, because in this case, both the rootstock and the scion are in an energetic and ready state. If the temperature and humidity are more suitable, the survival rate of grafting will be higher.

5. Grafting process

The grafting of rose stump is generally realized by sticking buds, first of all, cut the rootstock on the main branch of the rootstock, the cut depth is just enough to see the woody part, and the size of the incision should be consistent with the size of the scion bud. Because the two are not coordinated, there may be insufficient fit, not close under your high, it is easy to lead to grafting failure. Then cut 1-2 cm long buds on the scion, attach a little woody composition to the lower end, then stick it tightly to the grafting interface of the rootstock, let the cambium align with each other, and finally wrap the grafted part with a grafting belt.

VI. Maintenance and management

After the completion of the grafting activities, the following maintenance and management work is also very important. Because the buds in the grafting process have not been integrated with the rootstocks, and the leaf buds of the rootstocks will sprout in large quantities, which will inevitably consume a lot of nutrients, thus reducing the survival effect of the buds, weakening their growth, and may even lead to the death of the buds. Therefore, during this period, we can not allow it to grow wildly, we need to wipe off the new buds on the rootstock in time, and we also need to do a good job in the prevention and control of diseases and insect pests on the rootstock. Through careful maintenance, if it goes well, the tender green buds can be seen on the buds in about a month, and the healing tissue will grow gradually, and the grafting work will be basically successful.
