Cultivation method of Magnolia grandiflora: 1. Soil Magnolia grandiflora is suitable for weak acid or neutral soil with deep soil layer, and likes fertile and well-drained moderately moist weak acid soil (pH5-6), but it can also grow in alkaline soil (pH7-8), and it will not grow well when the soil is poor.

2. The root system of Magnolia grandiflora is fleshy root. Therefore, from early summer to late autumn, water should be poured once a day to keep the soil moist, but in hot summer, water should be poured once in the morning and evening, and water should be sprinkled on leaves and flowerpots to increase the air humidity.

3. Fertilized Magnolia grandiflora is a kind of fertilizer-loving flower, because it has a long flowering period and many flowers. Therefore, adequate nutrition is the basis of its flowering. Usually, in the flowering period from May to 65438+1October, in addition to applying base fertilizer to the upper basin, organic liquid fertilizer, such as decomposed cake fertilizer and water, should be applied every 5 to 7 days. The principle of fertilization is to apply dilute fertilizer frequently.

4. Pruning magnolia branches has poor wound healing ability and is generally not pruned. However, in order to make the tree shape reasonable, in the early stage of leaf opening, long branches, dead branches, pest branches and branches that hinder the beauty of the tree shape should still be cut off.
