1、 Seed propagation method

The grapefruit can grow completely in full temperature and humidity. But generally speaking, the potted pomelo trees planted and grown by themselves are only suitable for viewing. As for flowering and fruiting, they need more careful care

2、 Strip propagation

When the spring buds of grapefruit germinate in May, the branches that have grown stronger for two to three years can be peeled in a ring, and the substrate can be wrapped to the peeling place with a film. Keep the humidity of the substrate in a relatively humid state. After about one and a half to two months, roots can grow at the peeling place

3、 Cutting propagation

For potted grapefruit trees, cutting is a commonly used means. Give priority to those with a length of about 8 ~ 12cm, semi lignified, preferably with terminal buds. It would be better if they were stronger. For cuttings, remove half of the leaves from the branches and leave two to three leaves at the top. Cutting should be conducted in the plum rain season with appropriate temperature and high humidity. After cutting, pay attention to maintain the temperature and humidity of the substrate in the basin. Generally, the temperature should be controlled at 18 to 20 degrees Celsius, while the humidity should be about 50%. At the same time, it should be noted that the light intensity should not be too large. Generally, roots can be produced about two months after cutting

4、 Grafting propagation method

Grafting is also a common method for potted grapefruit trees. Branch grafting or bud grafting can be used. Generally speaking, it is appropriate to branch before the Spring Bud Germination of grapefruit, and bud grafting is appropriate in its growth period. In the selection of rootstocks, there are many kinds to choose. Generally, you can choose citrus aurantium or citrus aurantium, which have strong adaptability
