select excellent seeds. It is recommended to select the seeds harvested in the current year. The sowing environment is: temperature 20 ~ 30 ℃, air relative humidity 75 ~ 85%, and sufficient light

cutting propagation

cut two or three stem tips of about eight centimeters. After the incision is dried and shrunk, insert them into the matrix. Don't water them for the time being, put them in a semi shady place, and water them once after cutting for two days. If the cardinal coral encounters low temperature after cutting, it is necessary to take thermal insulation measures in time and wrap the flower pot used for cutting with film; In case of high temperature, timely cooling measures shall be taken to shade the cuttings. In order to ensure suitable humidity, spray at cuttings should be carried out at high temperature to reduce evaporation. p>

Strip propagation

Select healthy and strong branches from mature cardinal coral. Peel off a circle of bark about 15 ~ 30 cm below the top. The width of the wound is about 1 cm, and the depth has just stripped off the skin. Then use scissors to cut a piece of film with a length of 10 ~ 20 cm and a width of 5 ~ 8 cm. Put some wet soil on it, wrap the stripped bark with film, tie it into the upper and lower ends of the film, and drum up in the middle. Take root after about 4 to 6 weeks. After rooting, cut off the root system next to the branches, so that a new plant will grow into one
