The propagation mode of Rosa laevigata

Cutting: cut the small shoots and insert them into the ash. Keep the nutritive soil moist. Seal it with a film. Open it regularly for ventilation or use a toothpick to pierce several holes. Branching: the branchlets separated from the root of the mother plant can survive independently after being cut and planted on the substrate. Layering: bury the long growing branch in the soil, wet it with a watering can, take root after a period of time, and then cut it with a knife to maintain it.

I. sowing

It is said that the seeds of Rosa laevigata are very difficult to survive after planting, so there are not many people who use this method to cultivate.

2. Cutting

Compared with the previous method of sowing, this method is more used. Even in large-scale production, many people choose cuttings. With the healthy mother without disease on the small buds, cutting down immediately to operate, placing time is too long small buds will wither, in want to grow into a plant is not easy

The cut can be inserted into the ash to prevent the root from rotting. Insert the soil and adjust the temperature to about 24 ℃ at room temperature. Keep the nutritious soil moist. As long as the temperature and water conditions are stable, this method can be used in every season, but the temperature should not be too high, or the roots will rot, and the plants will grow slowly if they are too low. Considering the climate, it is most convenient to operate in spring and autumn.

After cutting, the substrate can be moistened with water, not too much water, and then sealed with film to reduce the loss of water, which also plays a role in heat preservation. In addition, after the film is wrapped, it is airtight. It can be disassembled regularly for air permeability. The troublesome flower friends can pierce several holes for air permeability.

3. Ramets

The twigs separated from the mother's roots can be taken out separately for survival. The branch and the mother connected to the place cut, planted on another substrate, you can survive independently.

4. Pressing

Select the old branch to strip. Observe the mother's branches. The branches that have been growing for a long time will be buried in the soil. Wet the soil with a watering can. After growing for a period of time, the plant will take root independently, and then cut it off with a knife and the mother body for water and light conservation, and it will survive.

5. Grafting

The advantage of this method is that the florescence comes quickly and beautiful flowers can be seen in that year. The grafted branches should be relatively old and survive well.
