The latest planting method of malachite

Malachite grass, also known as small marigold, red yellow grass, chamomile, stinky chrysanthemum, satin flower, etc., is an annual herb of Compositae marigold. It is native to Mexico and is often cultivated in gardens all over China. It has been naturalized in central and northwest Yunnan, central and southwest Sichuan and western Guizhou. Let's take a look at the planting methods of malachite.

Growth habits of malachite grass

Malachite grass grows in hillside grasslands or forests at an altitude of 750-1600 meters above sea level, or is cultivated in gardens and likes the sun, but it can also blossom when planted in semi-shade. The soil is not strict, it is not only resistant to transplanting, but also grows rapidly, and the cultivation and management is very easy. The seeds scattered on the ground can grow and grow in suitable temperature and humidity conditions, so it is a kind of flower with strong adaptability.

The Propagation method of Malachite

1. Sowing and propagation: the sowing and propagation of malachite is carried out from November to March, and blossoms from March to May when sowing in winter and spring. The sowing can be directly seeded in the courtyard or in the pot, and the seedlings can be dug up and planted in the pot about one month after sowing.

2. Cutting propagation: Malachite cuttings are cut from about 10 cm in length from June to August and cut directly into the courtyard, shaded and covered, growing rapidly, or directly in flowerpots. The summer and autumn cuttings blossom from August to December, and the cuttings can survive regardless of the place or bed (basin).

Planting method of Peacock Grass

1. Transplant the upper basin: the peafowl seedlings raised with a hole tray should be transplanted into the basin when growing to 2 to 3 pairs of true leaves. In Zhejiang, most of them are accustomed to using 12 cm diameter nutrition bowls, putting the pots in place at one time and not changing the pots again. If the seedlings are sown in an open seedling tray, they should be sowed sparsely, and when there are 2 or 3 pairs of true leaves, the seedlings should be transferred directly to the pot.

2. Light regulation: Peacock grass is a positive plant, which requires sufficient sunlight for growth and flowering, and sufficient light is also beneficial to prevent the overgrowth of plants. However, from July to September in our province, it is necessary to avoid direct sunlight and cool down by shading around noon.

3. Temperature control: the temperature of malachite grass can be reduced from 22 ℃ to 18 ℃ after potting, to 15 ℃ after a few weeks, and to 12: 14 ℃ before and after flowering. This temperature is ideal for forming a good plant shape, but it may be difficult to achieve this condition in practical production. Therefore, generally speaking, as long as it is more than 5 ℃, it will not be frozen, and it can grow well between 10 ℃ and 30 ℃.

4. Water management: the key to the water management of malachite grass is to use the medium with good drainage. Although it is important to keep the medium moist, it is necessary to dry properly before each watering. Of course, the medium can not be too dry and cause the plant to wither.

5. Fertilization method: for peacock grass cultivated completely in artificial medium, 20-10-20 and 14-0-14 fertilizers should be used, and the concentration of 200~250ppm should be applied alternately once every 10 days. When the temperature is low in winter, the use of 20-10-20 fertilizer should be reduced. If the medium is in ordinary soil, the compound fertilizer can be mixed as base fertilizer before the medium is put into the basin. If the fertility is not enough, then apply water-soluble fertilizer.

6. pest control: the common diseases of peacock grass are brown spot and powdery mildew, which are fungal diseases, so we should choose good cultivation, pay attention to drainage and irrigation, remove diseased plants and diseased leaves, burn residual branches, spray rust powder and other fungicides in time.
