Grafting Christmas cactus onto dragon fruit, one yellow coating and you still have to take a risk, learn these 2 tricks

The little gardener often browses Tieba, and his favorite thing to do is watch the "hands-on" experiments of expert flower friends. For example, there is a flower owner in the forum called "Bathed in Sunshine YZJ". He is a Christmas cactus enthusiast. He grows many Christmas cacti and has also made many attempts at Christmas cactus "grafting". Let's see how he uses "dragon fruit" to graft Christmas cactus.
1. Grafting Christmas cactus onto "dragon fruit"
The picture shows the Christmas cactus he grafted onto dragon fruit. He even specially wrote numbers on them for observation. This flower owner called "Bathed in Sunshine YZJ" said that before he had always used "Epiphyllum and cactus" for grafting, and this time he began trying something new: dragon fruit. Actually, we won't say much about the grafting steps. This expert has already mastered them through practice. Let's look at a few of the details.
2. The "yellow" coating, grafting little "treasures"
The first detail is that "yellow" coating on the wound. What is this thing? The expert says it is "callus", an antibacterial, antiseptic coating agent that promotes wound healing. Its effect is similar to other things commonly used by flower owners, such as carbendazim, plant ash, and sulfur. Carbendazim can also be used, flower friends.
3. Dare to "take a risk", grafted plants survive quickly
What is the second detail? This little owner is very bold. When cutting, he directly lets it receive light. This is actually a relatively "risky" practice and requires certain preconditions. The first precondition is that the leaf wound is not exposed, and the dragon fruit can cover the cut of the Christmas cactus grafted seedling leaf. The second precondition is that the sun can only be soft sunlight. Sun above 28 degrees or scorching sun will not work.
4. Supplemental fertilizer later, flowering is guaranteed
If flower owners want to learn to graft Christmas cactus, you can follow this "expert" flower friend. After the Christmas cactus grows and sends out branches, we still need to prune it appropriately. During regular care, it is best to use organic nutrient solution for strong roots to strengthen its roots. After the roots are strengthened, use a nutrient solution rich in phosphorus and potassium to promote flowering. With both approaches working together, the roots are strong and absorption is much better. Naturally, it can smoothly send out branches and bloom. This is natural.
5. A small watering detail, an old topic
Finally, let's talk about one small detail. That is, with grafted Christmas cactus, many little owners worry about watering. Actually, it is really not that delicate. For watering, just wait until the potting soil is dry before watering, and that's OK. What to note is that it is best to prepare a narrow-spout watering can and pour along the soil surface. Do not pour water along the dragon fruit or the Christmas cactus buds. That's OK.
For grafting Christmas cactus, this expert's experience is to first do the theoretical homework. Once you have accumulated enough, you can start doing it yourself. Keep trying, keep summarizing, and slowly, you will be the next "expert" flower friend.
