The germination temperature is 21 to 24 ° C, and the seedlings are emerged in about 7 to 10 days. The seedlings are extremely thin. Therefore, if the temperature is kept high, the seedlings grow very fast, and the relatively thick and fleshy branches and leaves can be formed. At this time, the seedlings can be directly placed on the basin, and the pots with a diameter of about 10 cm are used, and 2 to 5 plants are planted per pot, and the survival rate is high and the growth is rapid.

It can be sown in spring, summer and autumn. When the temperature is above 20 °C, the seeds germinate and germinate about 10 days after sowing. The cover soil should be thin and can grow without covering the soil. The seedlings were planted, and the row spacing was 5×6 cm. Need to apply liquid fertilizer several times. It can be flowered at about 15 ° C for about 20 days. Cutting propagation is often used for double-flowered varieties.

The row spacing is 30 cm in the ditch, and the horizontal ditch is 4-6 cm deep. Centimeter, do the flat, soil pine. The seeds need to be mixed with the ash of the manure mixed with manure, so that the seeds are ash, and the seeds are 5 to 6 per acre. When sowing, the human dung water is first applied in the ditch, and the seed ash can be evenly sprinkled.

Management: When the seed is raised, when the seedling height is one centimeter, pour a light human and animal manure to raise the seedling. When the seedling height is 3 to 4 cm, it is necessary to evenly seedling and replenish the seedlings. One seedling is kept every 3 to 4 cm, and the seedlings must be transferred with soil. After simmering the seedlings, weeding and weeding once, and topdressing in parallel. If the ramets are propagated, the new seedlings will be removed after planting, and the topdressing will be carried out once. After that, only the grass and soil will be pulled out, and after the harvest in September and the topdressing in November, each winter will be topdressed.
