Strip pressing method

In spring, plant drooping strips are pressed down and buried in the soil, cut off the next spring and planted

Generally, cutting propagation is the main method. The pot soil should be fertile soil with good drainage, and the flower pot should be placed in the sunny place after cutting

After flowering every year, it is necessary to cut off dead branches, weak branches and too dense and old branches, and pay attention to Rhizosphere Fertilization

Cutting method

Cutting can be carried out after falling leaves in autumn or before germination in spring, but it is best in spring. Generally, cutting in the south is more than open cutting in early spring, and cutting in the north is more in summer

The strong branches of 1-2 years old shall be selected in advance and cut into cuttings 20-30 cm long. The upper cutting opening shall be 0.8 cm away from the first node. The cuttings shall preferably have 2 or 3 nodes, and the lower end shall be cut into a plane near the node

Place about 1-2cm from the base of cuttings in 500ppmabt rooting powder or 500-1000ppm indole butyric acid solution for 10 seconds, take it out and dry it

When cutting ears, insert them obliquely, about 18-20 cm deep into the soil, expose the uppermost section of the branches to the ground, and then bury the soil for compaction

In case of drought, water frequently to keep the soil moist, but not too wet, otherwise the part inserted into the soil will be blackened and rotten

Under normal management, the cutting seedling rate can be as high as 90%. Strengthen field management. The seedling height can reach more than 50cm after autumn, and the hole can be dug and planted in the next spring

Ramet method

Ramets are usually after frost or before germination in spring

Dig out and transplant the young strips issued by the trees for more than three years with soil; Or dig out the whole plant and transplant it separately

Generally, a plant can be divided into 3-5 plants, but when cutting roots, each small plant must have a little fibrous root, which will improve the survival rate
