- Choose the right container it can be a seed tray or a pot. Note that, if you sow in a seed tray you have to transplant the seedlings when they become mature.
- Senecio plants are succulents so the soil must have good drainage. A good soil must be a combination between cactus mix and sand, pearlite, or any other material that helps to keep the substrate moist but not wet.
- Fill the pot with substrate but not before sterilizing both the container and the soil, in this way the plant won’t contract many diseases. The next step is moist the substrate and to spread the seeds over the substrate, these are little seeds so, it is a good idea to use a white paper or something that helps you to see where you are spreading the seeds. Spray them with water (do not add too much).
- Cover the pot with a glass sheet, a white paper, or a plastic bag to keep the seed warm. Put the container in a light shadow with a temperature of 21º C (70º F). The seeds will approximately germinate in ten or fourteen days.
- When the seedlings appear, make sure you remove the cover to allow air circulation and start putting the seedling in direct sunlight until they get accustomed to the sun. Do this process gradually, if you put the seeds in direct sunlight for long periods, in the beginning (they aren’t mature), they will suffer from sunburn.
- If you used a seed tray, you must wait until the seedlings are tall enough (typically 10 cm- 3.93 in), and then is time to transplant. When transplanting, do not forget to sterilize the new soil as well as the garden tools you are using. Also, do not forget to remove the old substrate from the roots. You may use hormone root to accelerate the process.
