1、 Breeding environment

1. Soil: it is best to use fertile and well drained soil for breeding Purple Magnolia

2. Moisture: water should be appropriate, and the basin soil should not be too wet, otherwise its leaves will turn yellow or even fall off. In hot summer, you can water once in the morning and evening, and spray water around appropriately to increase the humidity in the air. When it rains too much, there should be no ponding in the basin soil, otherwise the roots will rot, and drainage measures should be taken in time

3. Light: Magnolia needs sufficient light for its growth. If it is cultured in a cool place for a long time, it will be difficult to bloom. Give it more than 6 hours of light every day, but appropriately shorten the light time in summer and avoid direct exposure to strong light

4. Fertilization: Magnolia likes fertilizer. Because it has a large amount of flowers and a long flowering period, it should be fertilized in time to ensure sufficient nutrients. Fertilizer should be applied every 5-7 days from May to October. Generally, phosphorus and potassium fertilizer are the main fertilizer. Pay attention not to apply raw fertilizer, otherwise it may burn roots

2、 Breeding method

1. Grafting and propagation: it is best to rely on grafting at the place where the plant is 70cm away from the ground. After binding the main branches, wrap them with mud and wrap them with leaves. It can be cut off in about two months

2. Layering propagation: it is best to select the period from February to March, cut the pressed branches at half the depth, then cut them upward, put the tile in the middle, slowly put the branches into the soil, and finally pile the soil

3、 Common diseases and insect pests

1. Common diseases include root rot and yellowing. After getting sick, the diseased leaves should be removed in time, and then sprayed with carbendazim solution for control

2. Common insect pests include scale insects and aphids. In case of aphids, it is easy to stick the pests with cotton swabs stained with washing powder. Finally, clean the branches and leaves with clean water; Scale insects can be sprayed with acid and vinegar
