The biggest difference between Magnolia grandiflora and Magnolia grandiflora is the color, and other things, such as habits, are almost the same, so we can refer to each other's conservation methods in breeding.
Cultivation method of Magnolia grandiflora
Soil: Magnolia grandiflora likes loose and fertile acidic and slightly acidic soil, which can be cultivated by mixing humus soil and vegetable garden soil in equal amount, and adding 5-15g bone meal or NPK compound fertilizer to the soil.
planting: it can be planted in spring and autumn, and it should be carried out in the north after the land is thawed in spring. When planting, you should dig deep into the soil, apply decomposed organic fertilizer at the bottom of the hole, cover the base fertilizer with a thin layer of soil, and then put in magnolia grandiflora to stretch the roots. Watering is permeable after planting. After the plant survives, it is necessary to prevent drought in spring, pay attention to watering in time, prevent waterlogging in rainy season in summer, and discharge accumulated water in time. It is not allowed to water too much in autumn to slow down or stop its growth. Conducive to the maturity of branches and improve the ability to keep out the cold.
moisture: magnolia likes to be wet and is afraid of waterlogging, so it is very important to water it in a timely and proper amount. When beginning of spring blooms, the basin soil remains moist but not wet; After flowering, the basin soil remains moist without waterlogging; After defoliation, the basin soil can be kept slightly moist and not dried. No drought or waterlogging is allowed at any time, especially in rainy season.
Fertilization: Magnolia grandiflora likes fertilizer, so we should seize two key opportunities, February before flowering and May after flowering, and apply nitrogen, phosphorus and potassium compound fertilizer once every 1 days. The former makes buds expand and flowers bloom, while the latter promotes more pregnant buds and more spring flowers in the next year. Apply phosphorus and potassium-based fertilizer once in winter when defoliation occurs, so as to enhance its cold resistance and overwintering ability, and apply less or no fertilizer at other times. Avoid applying nitrogen fertilizer alone.
light temperature: Magnolia grandiflora likes light. It is placed in sunny courtyards and roof gardens. It is often seen that sunlight grows vigorously and luxuriantly. Although it can grow in semi-cloudy conditions, it is thin and has few flowers. If it is overcast, there will be no flowers. It is cold-resistant, and Beijing and its south area can overwinter outdoors.
