The plump core of grapefruit can grow and germinate completely and grow into grapefruit tree under suitable temperature and humidity conditions. But generally speaking, the potted grapefruit trees planted and grown by myself are only suitable for viewing. As for flowering and bearing, they need more careful care.
In May, when the spring buds of grapefruit germinate, the two to three-year branches that grow coarser will be peeled in a ring, and the substrate will be wrapped in a film to the peeling place. Keep the humidity of the substrate in a relatively wet state. After about one and a half months to two months, root system can be produced at the peeling place.
For potted grapefruit trees, cutting is a common method. It is preferred to choose the one with a length of about 8-12cm, semi lignification, and top bud, which is better if it is stronger. For cuttings, remove half of the leaves from the branch and leave two or three leaves at the top. When cutting, we should choose the plum rain season with suitable temperature and high humidity. Pay attention to keep the temperature and humidity of the substrate in the basin after cutting. Generally, it is better to control the temperature at 18-20 ℃, and the humidity at about 50%. At the same time, the light intensity should not be too large. About two months after cutting, root system can be produced.
Grafting is also a common way to plant grapefruit trees in a pot. Branch or bud grafting can be used. Generally speaking, it is more suitable to carry out branch grafting before Spring Bud Germination of grapefruit, while bud grafting is suitable during its growth period. In the selection of rootstock, there are many kinds to choose. Generally, you can choose citrus aurantii, such as tangerine or tangerine, which have strong adaptability.
