Saving a Rotting Desert Rose (Adenium): Water Management and Repotting

My Adenium in NC has a soft spot on the trunk with peeling bark. Leaves look OK. It's in a plastic pot, watered regularly. Should I repot to clay? What soil? Can I save it?

Diagnosis: Stem Rot from Overwatering

Adeniums (desert roses) are succulents adapted to extreme drought. The soft, peeling trunk base indicates rot from excess moisture. In Florida, I grow them in lava rock on a hot porch—water maybe monthly.

Immediate Rescue

1. Stop watering completely until soil is bone-dry
2. Remove from saucer—never let sit in water
3. Repot immediately into clay pot (breathable)
4. Use ultra-fast-draining mix: 50% perlite/pumice, 25% coarse sand, 25% cactus soil (NO fertilizer, NO Miracle-Gro)
5. Add drainage: Broken pottery, styrofoam chunks, or large bark at bottom

Can It Heal?

Yes, if rot is localized. Adeniums can callus over damaged areas if kept dry. The unaffected upper tissue can survive. Do NOT water until you see firm, new growth.

Ongoing Care

• Water once monthly in growing season (less in winter)
• Full sun, maximum heat
• Fertilize sparingly with low-nitrogen cactus feed
• Clay pot allows moisture to evaporate through walls

Your plant is salvageable. The key is benign neglect—treat it like a cactus, not a tropical.
