1. Cutting propagation: Choose healthy pitaya branches in spring, cut them to a length of about 15cm, and then dry the cuttings in the shade. Then insert it into the soil and wait for it to take root and sprout. 2. Grafting propagation: select healthy pitaya stems, cut them off and insert them into rootstocks with good growth conditions. After insertion, you need to tie them tightly with a rope to prevent them from falling off. After that, it was placed at about 28-30, and the grafting was successful in about 4 days.

Second, the maintenance method

1. temperature: because it likes high temperature, it is necessary to ensure that the annual average temperature is above 18. It is best not to let the temperature drop below 8 in winter. 2. Soil: weakly alkaline soil is preferred, and it is best to plant it on soil with pH of PH7.0-8.0. 3. Moisture: Although it has certain drought tolerance, it can't grow normally without enough moisture. During its growing period, it needs to be watered frequently to ensure that it has enough water to grow. 4. Lighting: It likes sunshine very much and can get sunshine. In a certain range, the stronger the sunshine, the faster the growth and the faster the nutrient accumulation. 5. Fertilization: Its growth needs sufficient nutrient support. Before the growing season, it should be filled with nitrogen fertilizer to help plants grow quickly. Before flowering, more phosphorus and potassium fertilizers should be applied to help it change from vegetative growth to reproductive growth, with more flowers and more fruits.
