- The best time to plant Pleiospilos is in late spring and summer. One of the most important things when sowing seeds are to give to them, air, light, and a warm temperature. If you are going to sow in another season, you should create an artificial environment with a heat mat and artificial lights.
- You can plant the seeds in a seed tray or a pot. If you choose the seed tray, be aware that the right moment to transplant the plant is when the seedlings are 10 cm (3.93 ins). By the way, these plants grow very slow so, it is recommendable to plant the seeds directly in pots if you do not want to wait too much. The Pleiospilos plants have long tap roots so, the adequate longitude of the container should be 10 cm (3.93 in).
- As any other succulent, the soil for a Pleiospilos plant must have good drainage, and it must be a combination between cactus mix and pumice (preferably), however, if you can’t find pumice the other option is to use a complete mineral mix.
- Fill the pot with the substrate, moist the soil with a spray, and in a softly way spread the seeds, it is not necessary to bury them, only sprinkle. Add an additional layer of pumice (approximately 1 cm/ 0,39 in) over the seeds. Proceed to cover the pot with a glass sheet, a white paper, or a plastic bag.
- Place the pot in a light shadow during this phase that generally has a duration of seven days. When the seedlings appear, wait one more week and start to expose them to the sun gradually. When the seedlings are accustomed to the full sun, move them from their current light shadowy place.
- If you chose the seed tray, once your seedlings are long enough is time to transplant to a pot. When doing note that you do not have to water them for a week after the transplant (read below to find the right moment for watering).
