The latest culture methods and points for attention of Michelia mollissima

Michelia flowers, also known as Michelia beauty, Michelia plum, mountain node, white orchid, banana, etc., are evergreen shrubs of Magnoliaceae, native to southern China, Dinghushan, Guangdong, wild, born in the shady slope forest, fragrant flowers and trees, bracts such as jade, fragrant if orchid, potted plants are the main ornamental plants, followed by garden landscaping. Let's take a look at the cultivation methods of Michelia flowers.

The growing environment of smiley flowers

Michelia peanuts in the shady slope mixed wood forest, especially lush along the valley, like fertilizer, half-shade, the most beneficial to growth in weak shade, avoid strong direct sunlight, pay attention to shade in summer, move into the greenhouse before the frost at the end of autumn, overwinter at about 10 ℃. Michelia is a warm woody shrub, not very cold-resistant, south of the Yangtze River leeward to the sun can overwinter in the open. Not resistant to dryness and barren, but also afraid of stagnant water, requires good drainage, fertile slightly acidic loam, neutral soil can also adapt.

Propagation methods of Michelia mollissima

1. Cuttage: Michelia cuttings are suitable for propagation from late July to early September. Lignified branches or terminal buds that have not yet issued new buds but have 3-8 leaves can be taken and placed on sandy soil with hairy root element at the base of cuttings. in addition, proper shading and keeping the environment moist can take root in about 2-3 months and then transplant in the next spring.

2. Circle branch: the propagation of Michelia mollissima wreath branch usually selects 2-year-old branches with good development and strong tissue in April. Do 0.5 cm wide girdling in the appropriate part of the branch, as deep as xylem, apply it to the girdled part with moist bryophytes, wrap it in plastic film, tie it up and down tightly, and take root in about 2 months. After the new root is fully developed, it is cut and cultivated in the pot. after cultivation, it should be watered thoroughly, and then watered once a day or not.

3. Grafting: the grafting propagation of Michelia should be carried out from May to June, and Magnolia is often used as the rootstock, which can grow rapidly after survival. Michelia mollissima with thick and succulent roots is not resistant to transplantation. if it is really necessary to carry out transplantation, it is appropriate to bring more soil balls, while the pruning and shaping of the plant is appropriate before overwintering.

Culture method of Michelia mollissima

1. Soil: Michelia is fleshy root, not resistant to dry and barren, but also afraid of stagnant water, requires good drainage, fertile slightly acidic loam, neutral soil can also adapt, can use 4 parts of rotten leaf soil, 3 parts of garden soil, 2 parts of rotten stable fertilizer soil and 1 part of sandy soil.

2. Watering: smile should keep the basin soil moist at ordinary times, but it should never be too wet. Because many of its roots are fleshy, such as too much watering or basin waterlogging after rain, it will turn into rotten roots, so we should pay attention to controlling humidity in rainy season. Need more water during the growing period and before flowering, watering once a day, high temperature in summer should be watered to the leaf surface to maintain a certain air humidity. It can be watered once or twice a week in autumn and winter due to short sunshine.

3. Sunshine: plants with a smile should not be exposed to the sun in summer and should be shaded by 30% so as not to burn the leaves by strong light. They can be placed indoors in windows and balconies facing east, and outdoors under shade or shade. You can see more sunshine when it is cool in autumn. Put it in the sunny ventilation place indoors in winter.

4. Temperature: the lowest temperature of Michelia mollissima overwintering is not less than 5 ℃. Once the temperature is lower than 5 ℃, the normal physiological activity of the plant will be affected, the absorption capacity of the root will be weakened, and the twigs and leaves of the plant will wilt. At the same time, the highest temperature should not exceed 15 ℃. If the temperature is too high, too much nutrients are consumed in the plant, which is disadvantageous to the growth of the next year. Therefore, it is suitable to keep the room temperature at 5 ℃ to 15 ℃ in winter.

5. Fertilization: Michelia likes fertilizer, and retting fertilizer such as rotten cake fertilizer, bone meal, chicken and duck manure and fish belly intestines are often mixed with water. Fertilizer is applied every 15 days in the growing season (from April to September), and fertilizer is stopped after flowering and October. If you find that the leaf color is not bright and thick green, you can apply fertilizer and water for once.

6, insect pests: Michelia often occurs shell insects, but also can induce soot disease, shell insects can be brushed off with a small brush, or with 150 times the water of the No. 20 petroleum emulsion spray, soot disease can be scrubbed with clean water or sprayed with water 500 times 1000 times carbendazim aqueous solution for prevention and control.

7. Pruning: Michelia flowers should not be overpruned. Usually, the overgrown branches, weak branches and overdense overlapping branches that affect the shape of the tree can be pruned after flowering, and the fruit after flowering can be subtracted to reduce nutrient consumption. Before sprouting in spring, remove some old leaves properly to trigger new branches and leaves.

8. Turn the pot: Michelia turns the pot every 1-2 years, preferably before the new leaves are released in spring, or after flowering, or in autumn. Combined with changing the basin to remove some of the old soil, replace it with fertile and loose soil, subtract withered branches and overgrown roots, and place sufficient base fertilizer in the basin.
