It can be opened in turn from April to September every year, which is resistant to pruning and pollution.

4. Breeding methods

The method of cutting propagation is mainly used in the production of Rosa multiflora, which can retain the excellent characteristics of plants. When cutting, select the semi-lignified branches of the year, trim them into cuttings of about six to ten centimeters, cut off the lower leaves, and keep two or three upper leaves. Cut it and put it in a cool environment, and then give it light gradually after ten days.
