I like a warm and humid environment. In winter, the aboveground parts withered, not cold-resistant, slightly drought-resistant. The requirements of the soil are not strict, the general land can be planted, we should pay attention to avoid stagnant water. Now let's introduce the specific planting methods of Xiancao:

[planting technology]

(1) the method of reproduction: seed propagation or ramet propagation.

1. Land selection and preparation: select the sunny sandy loam with good drainage, deep soil layer and rich humus in mountains, hills and plains. Full reclamation, turn 30 cm deep, remove weeds, apply bottom fertilizer, rake the broken soil flat, make a border 1.2 meters wide, and open a good drainage ditch.

2. Seed propagation: after the seeds were collected in September, the seeds were mixed and stored in wet sand. The seeds were sown between March and April the following year. When sowing, open 2-3 cm shallow trenches with a distance of 20 cm. After sowing the seeds, cover the fine soil, cover the seeds for the degree, then cover the grass with water, and then pay attention to maintain the soil moisture. When the seedlings are about 5 cm high, they can be interspersed properly. Two years later, seedlings were dug up and transplanted in winter and spring. The distance between holes was 20-25 cm, and 3-4 plants were planted in each hole. After planting, press the root and drench with water.

3. Ramet propagation: dig out the mother plant in winter and spring, peel off the tiller buds carefully, make each ramet with 1-2 buds, and plant 2-3 ramets in each hole directly.

(2) Field management

1. Weeding by mid-ploughing: as the whole growing period is long, weeding should be done once every other month.

2. Topdressing: nitrogen fertilizer was applied mainly in seedling stage. After planting, human feces and urine or compound fertilizer were applied once in spring and summer, and stable fertilizer, calcium superphosphate and turf mud were applied in autumn and winter respectively. It is necessary to cultivate the soil after each topdressing.

[pest control]

Black spot began to harm the leaf tip, yellowing and browning, gradually spread to the base of the leaf, and all the leaves withered. At the initial stage of the disease, one can be sprayed with Bordeaux liquid spray of 100 Bordeaux.

[harvesting and processing]

Spring is harvested before germination from February to April and autumn is harvested when plants wither from July to September. After digging out, remove the root head and whisker root, wash the soil and dry it.
