1. In order to ensure the survival rate of later planting, try to choose robust, nondestructive, thick and full seeds. Remove the outer epidermis, and soak in the solution for disinfection for about 15 minutes. Take it out and put it in a cool environment, and dry it naturally in the cool place.

2. The substrate needs ventilation and drainage, and can contain nutrients. Peat soil can be mixed with perlite, which can give consideration to both aspects at the same time.

3. Plant the seeds in the pot soil, keeping the height of loam 2cm, exposing the upper third of the pot soil, and burying the bottom to prevent the stems from rotting due to excessive watering.

4. After planting, put it in a sunny place to ensure sunshine. Insufficient light will lead to poor growth and development. If you think the protruding part of the stem is too short, you can put it in the dark for a few days to make the stem white and long, and then move it to a well-lit place for maintenance. The temperature should be controlled at 5- 10 degrees Celsius, not too low. Keep the basin clean.
