How to Grow and Care
Dorstenias are warm-loving plants, and they need a bit more water than regular succulents. They need a well-drained potting mix, and their water needs vary depending on the season of the year. Water regularly to abundant from spring to fall. Allow the soil to dry slightly between watering, but ensure that they never dry out completely. These plants tend to go at least partially dormant during the winter months. During this period, water very little. Giving plants a warm, sunny position can result in beautiful compact growing plants. Fertilizing plants once in a while during their growing period with a high potash and phosphorus fertilizer is recommended.
The spring weather with a high-temperature swing between the day and night hours and pretty frequent rains can favor the development of fungus diseases, which should be treated preemptively with a systemic fungicide.
Dorstenias are generally propagated by seed. Many species are self-fertile. Their seeds are expelled explosively from the mature seed heads and liable to populate pots several feet away. They can also be propagated by cuttings.
