1, the cutting time of the old stem of Rosa davurica must be selected, and the suitable time can greatly improve the survival rate of cutting. Under normal circumstances, cutting is carried out in winter or early spring, which can reduce the evaporation of water, and the climate in these two periods is conducive to the survival of cutting, so try to avoid summer, which is not easy to survive when the temperature is high.

2. Proper cuttings and excellent cuttings can improve the survival rate of cuttings. Choose a strong mother plant without pests and diseases, cut off the old stems with good growth from it, move quickly, keep the incision intact and remove the cuttings.

3. It likes slightly acidic soil. In order to improve the survival rate of cutting, we can choose to cut in ventilated, loose and well-drained sandy loam, disinfect the soil in advance, and spray wet water on the soil to keep it moist.
