"Famous Chinese Flowering Tree" When Does the Magnolia denudata Tree Bloom? How to Grow It Best? How Much Does One Cost?
Magnolia denudata is a variety of magnolia that bears white flowers, a famous flowering tree in China, and an important ornamental flowering tree in early spring in the north. It is cultivated extensively in Fujian, Guangdong, Guangxi, Yunnan and other provinces and regions of our country, as well as in the provinces and regions of the Yangtze River basin. So when does the Magnolia denudata tree bloom? How to grow the tree best? How much does one cost?
The flowering period of Magnolia denudata is from April to September.
How to grow the Magnolia denudata tree best
1. Propagation: The Magnolia denudata tree can be propagated by sowing, cuttings, layering and grafting. Sowing is mainly used to grow rootstock. For grafting, seedlings are used as rootstock, and cleft grafting, side grafting or bud grafting is performed. Cuttings can be taken in early June when the lateral buds of the new shoots are plump. Seedlings from sowing or grafting need heavy application of base fertilizer and density control, and sparse flower buds can be seen in 3 to 5 years. After planting, they enter the full flowering period in 2 to 3 years.
2. Potting soil: The Magnolia denudata tree prefers loose and fertile acidic or slightly acidic soil. For cultivation, a mixture of leaf mold and vegetable garden soil in equal amounts should be used as the growing medium, and 50—150 grams of bone meal or nitrogen-phosphorus-potassium compound fertilizer should be added to the soil. The pot is best slightly deeper and larger, and some broken hard plastic foam blocks should be placed at the bottom of the pot to enhance air permeability and drainage capacity and prevent root rot. Repot and change the soil once every year or every other year after the flowering period, retaining 1/2—1/3 of the old soil.
3. Water: The Magnolia denudata tree likes moisture and fears waterlogging, so it needs timely and appropriate watering. From the beginning of spring to the flowering period, the potting soil should be kept moist but not wet; after flowering, the potting soil should be kept moist without standing water; after the leaves fall, the potting soil should be kept slightly moist but not dry. The Magnolia denudata tree must never be drought-stricken or waterlogged at any time, especially in the rainy season, when attention should be paid to drainage and waterlogging prevention.
4. Fertilizing: Fertilizing the Magnolia denudata tree should seize the two key periods of 2 months before flowering and 5 months after flowering. During these two periods, a nitrogen-phosphorus-potassium compound fertilizer should be applied about once every ten days. The former can make the flower buds swell and the flowers bloom brightly, while the latter can promote more flower bud formation and more flowering in the following spring. When the leaves fall in early winter, a fertilizer mainly of phosphorus and potassium should be applied once to enhance the cold resistance and overwintering ability of the Magnolia denudata tree, and at other times it should be applied sparingly or not at all. The Magnolia denudata tree is averse to applying nitrogen fertilizer alone.
5. Light and temperature: The Magnolia denudata tree likes light. Normally it should often be placed in a sunny courtyard or rooftop garden to see more sunlight, so that it can grow luxuriantly and robustly. Under semi-shaded conditions, the Magnolia denudata tree can still grow, but it looks rather thin and weak and blooms little; if placed in a dark place for a long time, it will not bloom. The Magnolia denudata tree is a relatively cold-tolerant tree species and can overwinter outdoors in Beijing and areas to its south.
6. Pruning: The Magnolia denudata tree has extremely strong root sprouting ability. If propagation is not needed, the sprouts should be cut off as they grow, and each pot only needs to keep 3 main stems. For branches that are too tall and too long, they can be cut short after flowering when the leaves have just unfolded. Because the Magnolia denudata tree has poor wound-healing ability, sulfur powder should be applied after cutting for antisepsis; if not necessary, do not prune. After the Magnolia denudata tree flowers, if the seeds are not needed for propagation, the faded flowers should be cut off together with the calyx. Pruning and shaping can maintain the graceful tree form of the magnolia and make the flowers larger and more colorful the following year.
7. Pest and disease control: The Magnolia denudata tree commonly suffers from diseases such as black spot, leaf blight and leaf spot. In daily care, more attention should be paid to ventilation and fertilizer and water management. If disease occurs, measures should be taken promptly for treatment so as not to affect plant growth. The common insect pests of the Magnolia denudata tree mainly include the large bagworm, the ailanthus silkmoth and the pine hawkmoth. Prevention should also be noted during the planting period. If pests occur, corresponding insecticides should be sprayed promptly to kill the pests.
