1. Sowing and propagation

First, we need to collect its seeds, which is usually carried out from October to December. Save the collected seeds and sow them in the next spring. Sowing is usually carried out indoors. Before sowing, the soil should be selected first. The soil is generally loose, and the soil should be disinfected first

After the seeds are planted in the soil, cover them with a thin layer of soil, or not. Then lay a layer of fresh-keeping film on them to maintain humidity. Pay attention to poke several small holes in the film. Put it at a temperature of 20 to 25 degrees Celsius and it will sprout in about half a month. When two or three leaves grow, the film can be removed and gradually exposed to light. But you can't put it in the sun. When the seedlings grow 5 to 6 leaves, they can be implanted into the basin

2. Cutting propagation

The time of this reproduction is determined by the time it blooms. After it blooms, cut it from its bottom and put it in a 5 degree environment with the basin. Wait about a month to two months, it will grow new buds, and then it can be moved to a warm room. At this time, it is necessary to increase watering. After the new bud grows, you can cut off its too weak branches and leave stronger branches

3. Ramet propagation

This reproduction can be carried out when changing pots. Generally, after flowering in autumn and winter, turn the pot or change the pot when the pot soil is relatively dry. After we remove the plant from the flowerpot, we should first cut off the old roots and residual roots, and then naturally split it into small plants. Each small plant should bring some roots and foot buds, and then plant them on the seedbed respectively

4. Grafting propagation

We can collect seeds of Artemisia annua or Artemisia annua in autumn, or we can directly dig wild Artemisia annua seedlings in spring and plant them on the seedling bed. At this time, we should increase water and fertilizer to make it stronger. When the seedling grows to 10-16 cm from May to June, the rootstock can be cut 6-7 cm away from the ground. Then we need to trim it. After cutting for 14 days, we can adopt the method of splitting grafting

When grafting, first remove the leaves at the interface, pay attention to avoid the middle, grow about 2 to 3 cm, and then quickly insert the chrysanthemum bud. Finally, fix them and moisturize them with plastic bags until they survive
