What trees can be used as rootstock for grafting roses?
Roses are also known as Yueyuehong, Yueyuehua, Changchunhua, and are called the queen of flowers. They are erect shrub plants of the genus Rosa in the Rosaceae family. Their flowers are beautiful, varied in color, and bloom in all four seasons, making them deeply loved by people. China is one of the places of origin of roses. In May 1985, they were rated as the fifth of China's top ten famous flowers. Now let's take a look at what trees roses can be grafted onto!
What trees can roses be grafted onto?
When grafting roses, the main factor affecting survival is the compatibility between the scion and the rootstock. So-called compatibility means that the scion and rootstock are the same or similar to each other in internal tissue structure, physiology, and heredity, and thus can combine with each other. Roses and rose plants belong to the Rosaceae family. The best rootstocks for grafting roses are various wild roses, such as Shijiemei, Rosa davurica, Rosa banksiae, Rosa macrophylla, etc. These varieties have well-developed root systems, strong disease resistance, and vigorous growth, and can provide sufficient nutrients to the roses being grafted.
Grafting propagation techniques for roses
Wild roses are commonly used as rootstock for grafting roses, with two methods: bud grafting and branch grafting. Bud grafting has a relatively high survival rate and is generally carried out from August to September. The grafting site should be as close to the ground as possible. The specific method is to make a "T"-shaped cut in the bark on one side of the rootstock stem or branch with a budding knife, then select a bud from the middle of a well-grown current-year branch of the rose. After inserting the bud into the "T"-shaped cut, tie it with a plastic bag and provide appropriate shade. In this way, it can heal in about two weeks.
What are the benefits of grafting roses?
1. Vigorous growth: The rootstock used for grafting roses is vigorously growing wild rose, so the stems, leaves, and flowers are all noticeably superior to those of ground-planted roses.
2. Fewer diseases: The branches and leaves of grafted roses are higher above the ground, with good ventilation and light transmission, so there are almost no diseases.
3. Less space occupation: A traditional three-year-old ground-planted seedling occupies about 0.09 sq m, while a grafted rose occupies only 0.001 sq m.
4. Convenient management: The main trunk of the wild rose has no thorns, making it easy to manage, and the grafting height can be controlled, allowing arbitrary layout according to the form of the courtyard.
5. Multiple flowers on one plant: 3 to 5 varieties can be grafted onto one wild rose plant, and ten plants can reach more than 30 varieties, which is completely sufficient for courtyard cultivation.
