Cultivation Method of Yulan Flower
This article introduces the knowledge of Yulan flowers, including its cultivation method. The editor will provide you with a detailed explanation below.
Yulan flower, also known as white magnolia, magnolia, and early spring flower, is one of the unique and precious garden flowers in China, native to the Yangtze River Valley. It is still found in the wild in places such as Lushan, Huangshan, and Emei Mountain. The Yulan flower is as white as jade, with a fragrance similar to orchids. The tree is robust, with the tallest ones exceeding 10 meters in height, an ovate crown, large leaves that are obovate, short and pointed at the apex, wedge-shaped at the base, glossy on the surface. The branches are sparsely arranged, with young branches and buds covered with short villi. The winter buds have large scales. The flowers bloom before the leaves, terminal, large, 12-15 cm in diameter. There are 9 petals, shaped like a bell. The fruit spike is cylindrical and brown: the follicles split open when mature, with red seeds. The flowers bloom in March, and the fruits ripen from June to July.
Yulan flowers love sunlight and are relatively cold-resistant, able to survive outdoors during winter. They prefer dry conditions and dislike low humidity; waterlogging in the planting area can easily cause root rot. They thrive in fertile, well-drained sandy soil with a slightly acidic pH, but can also grow in weakly alkaline soil. In the warmer southern regions, they can bloom from December to January of the following year. Yulan flowers have strong resistance to harmful gases. If planted in factories with pollution from sulfur dioxide and chlorine gas, they have certain resistance and the ability to absorb sulfur. Artificially smoked with sulfur dioxide, 1 kilogram of dry leaves can absorb more than 1.6 grams of sulfur. Therefore, Yulan is an excellent tree species for pollution prevention and greening in areas with atmospheric pollution. The appearance of Yulan flowers is very similar to that of lotus flowers. When in full bloom, the petals spread in all directions, making the courtyard look snowy and bright, with high ornamental value; the sweet fragrance is refreshing and is ideal for beautifying the courtyard.
How to cultivate and manage Yulan flowers? Yulan is an ornamental flowering tree species with both color and fragrance in early spring. When planting, it is important to grasp the timing - not too early or too late. The most suitable time is 10 days before the spring germination or after the flowers have faded and before the leaves expand. When transplanting, regardless of the size of the seedlings, the roots should be kept with a ball of soil and care should be taken to minimize root damage to ensure survival. Before planting, sufficient well-rotted organic fertilizer should be applied as a base fertilizer in the hole. After planting, firm the soil and water sufficiently. Yulan flowers prefer fertilizer but not excessive amounts; generally, two applications of fertilizer during the growing period are beneficial for bud differentiation and growth. One application is in early spring, and another in May to June. The fertilizer is often well-rotted organic matter. Newly planted seedlings do not need to be fertilized, and fertilization can be done after defoliation or in the spring of the following year. Yulan has fleshy roots and does not tolerate waterlogging. During the flowering and growing period, the soil should be kept slightly moist. In the fall, watering should be reduced to slow down root growth of Yulan, promote branch maturity, and aid in overwintering. Generally, no watering is done in winter, except when the soil is too dry. Yulan has poor wound healing ability, so pruning is generally not performed. However, to maintain a reasonable tree shape, unnecessary long branches, dead branches, diseased branches, and branches that affect the aesthetic appearance of the tree should be pruned in the early stage of leaf expansion.
Additionally, if not saving seeds, the withered flowers and fruit spikes should be pruned after flowering to avoid nutrient consumption and affect the next year's flowering. Yulan flowers are mostly planted in the ground, but can also be grown as a tree-like landscape in pots.
