The first thing to prepare is the soil matrix. You can use sandy soil and add some perlite and peat.
Then there is the flowerpot. Triangle plum flower pot requirements are not high, simple plastic pot can.
Finally, prepare the branch to be cutted. Cut the strong branches that have been lignified or semi lignified in the same year.
Insert the cuttings into the mud block at a depth of about 7-8 cm to expose the branches with leaves.
After inserting, pour water through, cover the surface of the whole flowerpot with a layer of fresh-keeping film to keep the humidity, and put it in the place where the scattered light can shine.
The most important thing for the maintenance of Prunus triangularis is to moisturize and breathe.
If the moisture is not enough, the leaves will wilt and scorch. You should often check. If the mud is dry and the leaves wilt, spray some water.
Open the fresh-keeping film every evening and ventilate properly. It's too hot inside, the branches will get moldy, and the plants can't work.
High pressure propagation, i.e. high altitude strip propagation.
First, the survival rate is high. As long as the root system is not injured, the branches that are forced out of the root system can basically survive if they are cut and transplanted.
Second, there is basically no need to slow down seedlings.
Third, easy to form. After the branches are under high pressure, they will be transplanted into a new basin, and then they will grow into a healthy and beautiful bonsai flower with a little pruning.
First of all, the branches that need high pressure should be cut two inches above the fork of the female parent, with a width of about 3mm. And clean the outer skin.
Cover the branches with fertile and moist soil, and then fasten them with plastic bags at both ends.
The plastic bag will not lose water and dry after being wrapped. If the soil is dry, the syringe can be used for water injection.
More than a month later, many roots can be seen growing in the plastic bag, and then they can be cut and transplanted.
When transplanting, some soil can be piled up on one side of the flowerpot, so that the root group can lean against and the plant can grow upright.
Then cover the root with soil, compact and water, so that the high-pressure propagation of Prunus deltoides can be done!
