What are the latest propagation methods for Japanese maple?

The leaves of the Japanese maple (Acer palmatum) are similar to maple leaves, and the crown takes on an oval shape. Once the leaves of the Japanese maple turn red, it has very high ornamental value. Japanese maples can be seen in many parks in China, and there is also a certain area of Japanese maple cultivation. When planting Japanese maples, propagation is rather important, so how should Japanese maples be propagated? Below, the editor brings you the propagation methods for Japanese maple. Let's take a look together!

1. Grafting propagation

First, choose a Japanese maple with strong growth and vigor as the grafting rootstock, then carry out the grafting work when the rootstock is at its peak growth. First, transplant the seedlings about 3 times, starting after the rootstock has dropped its leaves; when transplanting, transplant with soil. The main grafting methods include cut grafting, bud grafting, and so on, and each method has different handling measures. For example, cut grafting is carried out around March each year, then the rootstock is cut off at a position about 60 cm above the ground for high grafting. This grafting method can ensure that new shoots reach about 55 cm. Approach grafting is rather troublesome to carry out, but its survival rate is relatively high; the bud grafting method is carried out many times, but it is not easy to survive.

2. Seed propagation

The fruit ripening period of Japanese maple is around October to November each year. After the fruit ripens, take out the seeds from the fruit. Then treat the seeds, do a good job of promoting germination and disinfection, improve the seed germination rate, and reduce the incidence of pests and diseases. After treatment, control the planting density on the planting soil, dig the sowing holes well, and then sow at the right time. After sowing, cover with an appropriate amount of soil, then water thoroughly to promote seed germination and seedling emergence. Then cover with a layer of grain crop straw to raise the soil temperature and prevent water loss. When the seedlings successfully break through the soil, remove the straw and do a good job of sun protection; if the seedlings are exposed to direct sunlight, it will seriously affect seedling growth. When the seedlings grow to about 40 cm, they can begin to be transplanted and planted out.

3. Cutting propagation

First, choose a robust, well-growing Japanese maple as the mother tree, then select good cutting branches. One week before cutting the branches, cut off the terminal buds on the branches, then after cutting them off, place the base of the branches in water, ensuring the part in water is about 4 cm. Cut the scions into small sections of about 10-12 cm, keeping the wounds as smooth as possible and retaining about half the number of leaves. Then use potassium permanganate to disinfect the soil, then cover with film for 2-3 days before cutting. When cutting, pay attention to density; after cutting, water thoroughly, keep the temperature at about 27 degrees, keep the field humidity at about 85%, then topdress fertilizer at the right time. Ensure sufficient water and nutrient supply for the growth of the Japanese maple.

The above three are a brief introduction to the propagation methods of Japanese maple. There are relatively many propagation methods for Japanese maple. The more common one is cutting propagation, because cutting propagation is relatively simple and has a short growth cycle. It is not recommended that everyone use seed propagation, because seed propagation takes a very long time and is not suitable for large-scale planting. That is all for today's introduction.
