Latest Cultivation Methods and Precautions for Yulan Magnolia Explained in Detail
The Yulan Magnolia (Magnolia denudata) has flowers as white as jade and a fragrance like that of an orchid. Its flowering period is short, yet it can bloom continuously all year round. Many people love it for its extremely high ornamental value, and it is grown by many people all across the country. Its tree form is tall, with the tallest reaching up to 10 m. It can be placed indoors, but it is not suitable for indoor cultivation. Let's take a look together below at the cultivation methods and precautions for Yulan Magnolia.
Cultivation Methods for Yulan Magnolia
1. Soil
Yulan Magnolia is suited to growing in deep, slightly acidic or neutral soil. It prefers fertile, appropriately moist, well-drained, weakly acidic soil and does not tolerate saline-alkaline soil.
2. Watering
The root system of Yulan Magnolia is fleshy, and it does not tolerate waterlogging. During the flowering and growing period, the soil should be kept moist. After autumn begins, watering should be reduced to slow root growth, promote branch maturity, and help it overwinter. In winter, generally no watering is done; water only once when the soil becomes too dry.
3. Light and Temperature
Yulan Magnolia grows best in an environment with ample sunlight. Sufficient light makes its branches and leaves lush and its flowers more numerous and fragrant. Insufficient light will cause poor development. Yulan Magnolia is also rather sensitive to temperature; too high a temperature will cause it to bloom early. It can briefly endure a low temperature of minus 20°C, but when the temperature falls below minus 20°C, cold-protection measures must be taken.
4. Fertilizing
Yulan Magnolia likes fertilizer but dislikes heavy fertilizer. During the growing period, applying fertilizer generally 2 times is enough to promote its growth and flower bud differentiation. The fertilizer used is mostly fully decomposed organic fertilizer. Newly planted saplings may go without fertilizer, and fertilizer should be applied after leaf fall or in the following spring.
5. Pruning
The branches and trunk of Yulan Magnolia have poor healing ability, so it is generally not stimulated. However, for a reasonable tree shape, water sprouts, dead branches, diseased and pest-infested branches, and other branches that spoil the tree's appearance should be pruned.
Precautions
1. Fear of Alkali
Yulan Magnolia prefers acidic soil, with a soil pH requirement of 5.5-6.3. If the soil is on the alkaline side, it will cause the protoplasm of its cells to dissolve, resulting in slow flower development and poor growth. Fermented rice-washing water can be used for watering, with good results.
2. Appropriate Moisture
Yulan Magnolia has fleshy roots. When the soil becomes waterlogged, its leaves turn yellow and drop, and the roots may even rot and the plant die. When too dry, the leaf tips wither and the leaves curl. It is a flower that fears both waterlogging and drought, so watering must be done with care.
3. Fear of Concentrated Fertilizer
Yulan Magnolia likes phosphorus and potassium fertilizer, but it dislikes excessively high fertilizer concentration; otherwise, reverse osmosis will occur, causing physiological drought. In mild cases it wilts, and in severe cases it is burned to death. Its fertilizing principle is to apply diluted fertilizer, apply it often, and apply it in the evening.
