Rosa laevigata, also called the "king's fruit," how is it propagated?

Rosa laevigata has high medicinal value. As its value continues to be developed, people pick wild varieties without restraint, causing wild numbers to drop sharply, and only artificial cultivation can ensure market demand. So “how is the king's fruit” Rosa laevigata propagated?

1. Seed propagation

Seed propagation is the most common propagation method. With seed propagation, you mainly raise seedlings first, and after the seedlings are successful, you transplant them, but the survival rate of seed propagation is very low, because the seeds have very strict requirements for the surrounding growing environment. If the requirements are not met even slightly, then the seeds' germination and emergence will be greatly hindered, or they may even fail to germinate, so generally when propagating, seed propagation is not recommended.

2. Division propagation

Division propagation mainly involves selecting Rosa laevigata plants with strong growth, thick stems and well-developed root systems, cutting off the small branches growing from their roots and stem bases, and then planting them, letting the divisions grow into independent plants. Compared with seed propagation, the division method has a higher survival rate and is relatively simple, but the yield is smaller, and it is generally used for various ornamental garden Rosa laevigata plants.

3. Cutting propagation

Cutting propagation is the most commonly used propagation method for Rosa laevigata. First, choose a Rosa laevigata plant with thick branches and no pests or diseases as the mother plant. Then choose branches as cuttings. After collecting the cuttings, insert them promptly to prevent wilting caused by lack of water or nutrients. When inserting the cuttings, pay attention to disinfecting the cut surfaces of the cutting branches, and maintain a certain temperature, not too high or too low; too high easily causes the cut to rot, and too low hinders the cuttings from rooting. Cutting propagation has a high survival rate and also higher yield, and it is the propagation method growers prefer to use.

4. Layering propagation

The layering propagation method mainly involves pressing the plant's vines into a nutrient solution, then waiting until the vines root before separating the rooted part from the mother plant, and planting it to form a new plant. The layering propagation method has a relatively high survival rate, but the propagation coefficient is not large. It is generally used when other propagation methods are not very effective, or when the planting area needs to be expanded. When choosing layering propagation, pay attention to the superiority of the mother plant; do not choose plants with severe disease, thin and weak branches, or poor growth.

5. Grafting propagation

Grafting propagation, like layering propagation, is a vegetative propagation method for Rosa laevigata. The grafting propagation method has both advantages and disadvantages. The advantage is that the plants have a high survival rate and grow quickly, which can speed up the recovery of costs, but the downside is that the yield may not be very ideal and requires careful management, so grafting propagation is usually used on potted Rosa laevigata.

The above is Tuliu.com's introduction to the propagation methods of Rosa laevigata. There are many propagation methods for Rosa laevigata. When propagating, everyone should also pay attention to reasonably using various propagation methods according to their own planting conditions and planting direction, so as to ensure the economic benefits of planting.
