Move the plant when the caudex or roots fill the pot, roots threaten breakage, drainage has degraded, or the plant is declining in an unknown nursery mix. Some crowding is tolerated. Annual repotting is not required.
How to repot Adenium obesum
Repot a desert rose when its caudex or roots fill the container, drainage declines, or the plant is declining in an unknown nursery mix. Warm active growth is the routine window.
Check the roots, mix and drainage
When to repot
Use the warm growing season, as early in active growth as practical. Avoid routine fall and winter repotting. Climate and growth state matter.
Use the smallest practical size increase
Choosing the next pot
Choose a pot with several unobstructed drain holes and little more room than the root system needs. Avoid an oversized container, a narrow neck or a saucer that holds water. A shallow, wide pot can dry faster and show the caudex, but it is optional.
Move the rootball without unnecessary damage
How to repot
Use porous succulent medium, lift the plant without burying the caudex deeper than intended, and avoid a large wet volume around a small root system. Gradual caudex elevation is an optional cultivation choice.
Keep light, water and support steady
After repotting
Keep the repotted plant warm and bright and protect it from frost and cold, wet conditions. If roots were not significantly damaged, watering can resume immediately. During winter rest, water may be reduced or withheld.
