For Ulmus pumila, there are many ways to reproduce, almost all of which are suitable for it. There are five commonly used methods, namely grafting, cutting, splitting, layering and sowing.
1. Grafting: bud grafting and branch grafting can be done, but the time is different. Budding can be at the end of August, and branch grafting can be in spring. First of all, rootstock should be selected, and the seedlings of Rosa species can be planted. Then choose a strong mother plant, and choose the branches above the last year as the scion. After selection, the scion will be grafted on the rootstock, careful maintenance can
2. Cutting method: the best way to use this method is to use the healthy shoots that were born in the same year at the turn of spring and summer. After cutting off the branches, you should choose the most robust part, which is five to fifteen centimeters long, with at least three nodes. Then prepare the matrix with good air permeability. Then insert the insert into the substrate obliquely, and cure it carefully.
3. Branch method: it can be carried out in spring or autumn. Choose a strong and prosperous mother plant and divide it into several parts from the root. Trim each piece to reduce evaporation. After that, we can plant them separately.
4. Layering method: select the strong branches first, and strip the bark away from the top 15 to 30 cm. Then wrap the part with a piece of plastic film and tie it tightly. It will take root in about a month and a half.
5. Sowing method: in spring and autumn. Choose full seeds, sow them on the plump soil, and cure them carefully.
