Christmas cactus can be grafted onto a variety of plants, and it grows very vigorously.

Three-ribbed cactus (Hylocereus undatus): the three-ribbed cactus is the most suitable plant for grafting Christmas cactus, because the three-ribbed cactus also belongs to the cactus family. The three-ribbed cactus has a very strong reproductive capacity, is very easy to care for, and roots quite easily. The survival rate of grafting Christmas cactus is very high, and after grafting onto the three-ribbed cactus it looks very beautiful, making it suitable for beginners to care for.
Cactus (Opuntia): cactus can also be grafted onto many plants. The pads of the cactus are very thick and fleshy, making grafting very convenient, and the method is relatively simple. After grafting it also readily survives, and once it has taken, it grows very well too. It is best to choose an upright cactus for grafting, as the grafted cactus then looks quite beautiful and even more attractive.
Grafting Christmas cactus onto Pereskia (leaf cactus): using Pereskia to graft Christmas cactus makes survival very easy, and the compatibility of grafting Christmas cactus onto Pereskia is very good. After a successful graft, the growth is also very vigorous, but the branches of Pereskia are relatively soft, so to make the Christmas cactus look nice, it needs a support to hold it up, so that it looks more upright.
