Rosa davurica likes warmth and is not cold-resistant. It grows best at around 22℃ during the day and around 65,438 05℃ at night. When it is kept at 65,438 05℃ to 20℃ in the greenhouse, it can bloom all year round. When the temperature is reduced to 10℃, the fallen leaves will turn into semi-dormancy, and new leaves will be released in the next spring to continue flowering. Tiger thorn plum likes light. The more sunshine before flowering, the brighter the flowers will be. If it lasts for a long time, the color will be dim. If it is kept in the shade for a long time, it will not bloom. Also pay attention to keep the air circulating. Rosa davurica fruit can be used as base fertilizer by using cultivated soil to pad hoof horn pieces, and fertilized once every half month during the growing period. After autumn, fertilization should be stopped to prevent root rot. Rosa davurica is drought-tolerant, so watering in spring and autumn should be dry and wet. Water once a day in summer, prevent waterlogging in rainy season, do not water in winter, and the basin should not be wet for a long time; Water should also be controlled during flowering period, which is easy to cause falling flowers and rotten roots. In late spring and early summer, May-July, the cuttage of Rosa davurica is the easiest to survive. Select stout branches, about 10cm ~ 15cm long, dry the white pulp flowing from the incision, coat it with plant ash, and dry it in the shade for 2 ~ 3 days. After the wound is dried, insert it into plain sand, pour it thoroughly with water, then pour it less, and then pour it after the basin soil is slightly dry.
