Adeniums, often called Desert Roses, do require a bit more attention than some other succulents. They thrive in bright, indirect sunlight but can also handle direct morning sun. For watering, it's crucial to let the soil dry out completely between waterings to prevent root rot. A well-draining soil mix, such as a cactus mix with added perlite or sand, works best. Fertilize during the growing season with a balanced water-soluble fertilizer, diluted to half strength.
Personally, I've found that consistent monitoring and adjusting for your specific climate is vital. In more humid environments, you might water less frequently. One challenge is keeping an eye out for pests, like spider mites or mealybugs, which can be problematic.
Have you tried experimenting with different soil mixes or fertilizers? It might be interesting to see how your adenium reacts to minor changes in its care routine.
