Weather has a great influence on grafting, so grafting should be carried out in sunny days and at 20 ℃. In other cases, grafting will leave hidden dangers and affect flowering.
The thick cactus is the most suitable rootstock. Cactus is cold resistant, weak in row, and easy to survive by grafting. The rootstock for grafting is about 30 cm higher than the basin surface, which is conducive to the later leaf stem suspension.
The scion should be light green, thick and strong with high survival rate. When the scion is about to blossom, the leaf ear should be selected. One ear should be grafted at a time instead of one. Too many scions will affect the flowering.
When grafting, the water evaporation of scion should be reduced. Usually, the rootstock should be cut first, and then the scion should be cut. The slice of Christmas Cactus is thin. Be careful when handling it. Use a sharp blade to scrape it gently. Don't cut it directly.
After the scion is inserted into the rootstock, the rootstock and the cuttings shall be closely fitted without gaps, and the binding tightness shall be moderate. The surrounding air is relatively dry and can be covered with plastic bags for 3-4 days.
2-3 days after grafting, the grafting surface is good, and the rope can be untied. After loosening the binding, put the plant in a cool place, observe it carefully for 20 days, and then water it after confirming its survival, and then move it to the sun for normal management.
