1. Seed harvesting

If you want to choose seeds well, you should first determine a mother plant, and then strengthen management. After the flowers bloom, they should be artificially pollinated. Use a brush as a tool to smear pollen. After that, we should pay special attention to the fertilizer and water management of the mother plant, and timely treat diseases and pests. In this way, full seeds can grow. After the seeds are developed, they can be picked and put in a paper bag in a ventilated and dry place

2. Choice of time

It's best in autumn, usually in October. It is best to sow after the temperature drops to 20 degrees. At this time, the survival rate is high. However, there will be slight differences in time according to the differences of different regions

3. Treatment of seeds

Before sowing, the seeds should be treated. Generally speaking, it is the method of using low temperature to promote germination. Wrap the seeds in gauze, put them in cold water for a whole day, and then refrigerate them in a refrigerator at 8 to 10 degrees

4. Selection of soil

Preferably loose, fertile and acidic soil. It can be mixed with garden soil, sandy soil and animal manure in a ratio of about five to three to one

5. Sowing and subsequent curing

After the seeds are treated, they can be sown in about ten days. The seeds should be spread evenly on the surface of the soil. After that, the temperature should be controlled, about 15 to 20 degrees. In addition, ensure humidity. The light should not be too strong
