Desert rose soil: indoor and outdoor settings
Choose the growing setting first. Adenium obesum needs a porous, sharply draining container mix. Indoor pots and warm-climate outdoor pots can use different materials, so there is no single recipe.
Check how the mix holds water and air
Best soil mix
For a container, use a porous mix with coarse pumice, coir, sand, gravel or perlite in warm regional conditions. The indoor direction separately lists rich organic peat- or bark-based bagged potting soil. These directions are context-specific, not one interchangeable recipe.
Give Adenium obesum unobstructed drain holes and excellent drainage. Do not leave the pot on a saucer that holds water. Wet soil can lead to root rot, and drought tolerance does not make standing water safe.
Separate indoor and outdoor advice
Match the mix to the pot and setting
This page covers potted Adenium obesum in temperate indoor settings and warm patio or regional outdoor conditions. Keep the indoor, patio and warm-climate branches separate. A warm outdoor recipe is not an indoor schedule.
Use an exact target only when one is known

Check the pot, watering and roots too
When soil alone is not the problem
