A Detailed Guide to the Cultivation Methods and Precautions for Magnolia denudata
The flowers of Magnolia denudata are as white as jade, and their fragrance resembles that of an orchid. Its flowering period is reduced, yet it can bloom continuously throughout the year. Many people like it, and its ornamental value is extremely high. It is cultivated by many people all over the country. Its tree form is tall, with the tallest reaching 10 m. It can be placed indoors, but it is not suitable for indoor cultivation. Let's learn about the cultivation methods and precautions for Magnolia denudata together with the editor below.
Cultivation Methods for Magnolia denudata
1. Soil
Magnolia denudata is suitable for growing in slightly acidic or neutral soil with a deep soil layer. It prefers fertile, appropriately moist, and well-drained weakly acidic soil, and is not tolerant of saline-alkali soil.
2. Watering
The root system of Magnolia denudata is fleshy, and it is not tolerant of waterlogging. During the flowering and growth period, the soil should be kept moist. After the beginning of autumn, watering should be reduced to delay its rooting, promote the maturity of the branches, and help it overwinter. In winter, it is generally not watered, and it is watered only once when the soil is too dry.
3. Light and Temperature
Magnolia denudata is suitable for growing in an environment with sufficient sunlight. Sufficient light can make its branches and leaves luxuriant and its flowers more numerous and more fragrant. If there is insufficient light, it will develop poorly. Magnolia denudata is also relatively sensitive to temperature. Too high a temperature will cause it to bloom earlier. It can endure a low temperature of minus 20 degrees for a short time, but when the temperature is below minus 20 degrees, cold protection measures should be taken.
4. Fertilization
Magnolia denudata likes fertilizer, but it is averse to heavy fertilizer. During the growing period, applying fertilizer generally 2 times is enough to promote its growth and flower bud differentiation. The fertilizer is mostly fully decomposed organic fertilizer. Newly planted saplings may not be fertilized, and fertilization should be carried out after leaf fall or in the spring of the following year.
5. Pruning
The branches and trunk of Magnolia denudata have a relatively poor healing ability, so it is generally not stimulated. However, in order to keep the tree shape reasonable, water shoots, dead branches, diseased and pest-damaged branches, and other branches that hinder the beauty of the tree shape should be pruned.
Precautions
1. Afraid of Alkali
Magnolia denudata likes acidic soil, and its requirement for soil pH is 5.5-6.3. If the soil is alkaline, it will cause the dissolution of its cell protoplasm, resulting in slow flower development and poor growth. Fermented rice washing water can be used for irrigation, with good results.
2. Water Must Be Appropriate
Magnolia denudata has fleshy roots. When the soil is waterlogged, its leaves will turn yellow and fall off, and even the roots will rot and the plant will die. If it is too dry, the leaf tips will wither and the leaves will curl. It is a flower that fears both waterlogging and drought, so watering must be done with care.
3. Afraid of Concentrated Fertilizer
Magnolia denudata likes phosphorus and potassium fertilizers, but it is averse to excessively high fertilizer concentration, otherwise reverse osmosis will occur and cause physiological drought, ranging from wilting in mild cases to being burned to death in severe cases. Its fertilization principle is to apply diluted fertilizer, apply it frequently, and apply it in the evening.
