Cultivation methods:
Duvalia hirtella (Jacq.) Sweet var. obscura N.E.Br. is a succulent plant that is relatively easy to grow in both indoor and outdoor settings. It prefers hot, dry conditions, making it an excellent choice for desert gardens or xeriscape landscapes.
When growing indoors, make sure to provide a sunny location or use artificial grow lights. The plant prefers well-drained soil and a pot that has drainage holes.
Watering needs:
As a succulent, Duvalia hirtella var. obscura does not require frequent watering. Overwatering can lead to root rot, so it's important to let the soil dry out between watering. In the summer, once a week is usually sufficient, while in the winter, it can be watered every two to three weeks.
