How to grow purple magnolia

1. Breeding environment

1. Soil: It is best to use fertile, well-drained soil for growing purple magnolia.

2. Water: Water in moderation and the soil in the pot should not be too wet, otherwise its leaves will turn yellow or even fall off. In the hot summer, you can water the plant once in the morning and once in the evening, and spray water all around appropriately to increase the humidity in the air. When it rains too much, there should not be water accumulation in the potting soil, otherwise the roots will rot, and drainage measures must be taken in time.

3. Light: Purple magnolia needs sufficient light to grow. If it is kept in a cool place for a long time, it will be difficult for it to bloom. It should be given more than 6 hours of light every day, but in summer the light time should be shortened appropriately and direct sunlight should be avoided.

4. Fertilization: Purple magnolia likes fertilizer. Because it blooms in large quantities and has a long flowering period, it is necessary to fertilize in time to ensure sufficient nutrients. Fertilize once every 5-7 days from May to October. Generally, phosphorus and potassium fertilizers are used as the main fertilizers. Be careful not to apply raw fertilizers, otherwise it may burn the roots.

2. Breeding Methods

1. Grafting propagation: It is best to graft the plant 70 cm from the ground. After tying the main branches, wrap them with mud and leaves. Wait for about two months and then cut them off.

2. Layering propagation: It is best to choose the period from February to March, cut the branches to half the depth, then cut upwards, put a tile in the middle, slowly put the branches into the soil, and finally pile up the soil.

3. Common pests and diseases

1. Common diseases include root rot, chlorosis, etc. After the disease occurs, the diseased leaves should be removed in time and then sprayed with carbendazim solution for prevention and control.

2. Common insect pests include scale insects and aphids. If aphids appear, you can use a cotton swab dipped in laundry detergent to remove the pests, and finally wash the branches and leaves with clean water; scale insects can be killed by spraying with vinegar.
