Light
Direct sunlight is essential for the healthy growth of the Desert Rose. Place it in a spot where it receives at least 6 hours of direct sunlight a day, preferably in the morning or afternoon.

The soil for Adenium obesum should be well-drained to avoid water accumulating around the roots. A mixture of sand, perlite and organic matter may be ideal to promote proper drainage.
Water
Although it is a succulent plant, the Desert Rose needs regular water during the active growth period in spring and summer. However, it is important to let the soil dry out between waterings to avoid root rot.
Temperature and humidity
This plant thrives in hot, dry climates, preferring temperatures between 25°C and 35°C during the day and no less than 15°C at night. Air humidity is not a critical factor, but avoid very humid environments to prevent fungal diseases.
Fertilizing
During the active growing season, which occurs in spring and summer, you can fertilize every two weeks with a balanced fertilizer, diluted by half. During the dormant period in autumn and winter, reduce fertilizing to once a month or stop it altogether.
By following these care tips, you can enjoy a healthy and lush Desert Rose in your garden or indoor space.
How to make Adenium obesum cuttings
If you want to propagate new Adenium obesum plants, the process of making cuttings can be an interesting and rewarding option.
Choice of material:
To make an Adenium obesum seedling, choose a healthy and vigorous mother plant. Look for a side branch that is at least 10 centimeters long and has 2-3 healthy leaves.
Preparing the cutting:
Cut the cutting using a sharp, sterilized blade to avoid infection. Make sure the cut is clean and made at a 45-degree angle to increase the area for absorbing water and nutrients.
Rooting the cutting:
Let the freshly cut cutting dry out in the open air for a few days to form a protective bark at the end of the cutting. Then plant the cutting in a well-drained substrate, such as a mixture of sand and perlite.
Care during rooting:
Place the cutting in a location with partial shade and keep the substrate slightly damp, but not soaked. Avoid overwatering to prevent the roots from rotting.
How to plant Adenium obesum
Once the roots have developed, which can take a few weeks, you can transplant the seedling into a larger pot or directly into the garden. Make sure you provide adequate sunlight conditions and continue the care as described in the previous section.
With patience and proper care, your Adenium obesum seedlings will grow and thrive, adding beauty to your green space.
