What tree is used to graft roses? The latest rootstock selection guide
The rose is also known as Yueyuehong, Yueyuehua, Changchunhua, etc., and is called the queen of flowers. It is an upright shrub plant of the genus Rosa in the Rosaceae family. Its flowers are beautiful and elegant, with diverse colors, and it blooms in all four seasons, so it is deeply loved by people. China is one of the places of origin of the rose. In May 1985, it was rated fifth among China's top ten famous flowers. Now let us take a look at what trees can be used to graft roses!
What trees can be used to graft roses?
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 genetics, and thus are able to combine with each other. Roses and rose plants belong to the Rosaceae family. The best rootstocks for grafting roses and rose plants are various wild roses, such as Shijiemei, Rosa davurica, Muqiang rose, Rosa macrophylla, etc. These varieties have well-developed root systems, strong disease resistance, and vigorous growth, and can provide sufficient nutrients for the roses to be grafted.
Grafting propagation techniques for roses
For rose grafting, wild roses are commonly used as rootstock, and there are two types: 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 use a budding knife to make a “T”-shaped cut in the bark on one side of the rootstock stem or branch, 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 grafted roses is vigorously growing rose, so the stems, leaves, and flowers are all noticeably better than those of ground-planted roses.
2. Less disease: The branches and leaves of grafted roses are higher above the ground and have good ventilation and light transmission, so there is almost no disease.
3. Less space occupied: A traditional three-year-old ground-planted seedling occupies about O.09 sq m, while a grafted rose occupies only O.001 sq m.
4. Convenient management: The main stem of the 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 rose plant, and ten plants can reach more than 30 varieties, which is completely sufficient for courtyard cultivation.
