The cultivation methods and precautions of magnolia

1. Maintenance methods

1. Temperature: A warm environment is suitable for magnolia growth, which can be between 20 and 28 degrees. It has a certain degree of cold resistance. Generally speaking, there is no need to protect it from the cold when growing it in the southern region. However, if you live in the north, try to keep it indoors.

2. Light: Magnolia is a light-loving plant. However, very strong light is not enough. Therefore, you can directly place it in a place with diffuse light but no direct light, and there is no need to move it or provide shade. In winter, no shade is required.

3. Watering: Magnolia is sensitive to water. It is a plant that is afraid of both drought and waterlogging. Therefore, neither too much water nor too dry. In addition, when it is very hot in summer, additional watering is needed, which can be done around 6 o'clock in the morning.

4. Fertilization: Fertilization is required four times a year, and the timing needs to be noted. The first time is before flowering, using compound fertilizer. The second time is after flowering, using nitrogen fertilizer. The third time is in July and August, mainly using phosphorus and potassium fertilizers. The last time is before winter, when organic fertilizer can be applied.

2. Breeding techniques

1. Reproduction: Sowing is commonly used. Selecting good quality seeds has a great impact on the germination rate. After that, they need to be soaked in water at about 50 degrees before sowing. The substrate can be sandy soil, which has a better effect, and some bone meal and other substances can also be mixed into it. Sowing can be done in rows. After sowing, keep the substrate moist.

2. Repotting: It is best to do so once a year. If the substrate is suitable, it can be repotted once every two years. Sandy soil can also be used as a substrate and mixed with base fertilizers such as bone meal. After changing the soil, place it in a cool place to allow the plant to adapt.

3. Problem diagnosis and treatment

1. Disease: There may be "chlorosis", the leaves will turn yellow and then white, and in the most serious cases, the whole plant may die. Ferrous sulfate can be used to irrigate the roots, and assisted by measures such as loosening the soil.

2. Pests: There are many types of pests, such as "longhorn beetles", "red spiders", "frost moths", etc. It can be controlled by using pesticides such as cypermethrin and green Weilei.
