Reviving a Declining Hoya: Root Rot Rescue and Propagation

Diagnosis

Yellowing, shriveling leaves and a mushy main stem indicate severe root rot, usually from overwatering or insufficient light. Hoyas need bright light with some direct sun and very well-draining soil that dries thoroughly between waterings.

Rescue Attempt

1. Take a 4–6 leaf tip cutting from a healthy portion.
2. Root in a 50/50 peat-perlite mix under a clear plastic bag with ventilation.
3. Keep warm (70°F+), in bright indirect light.
4. Water when top ½″ of mix feels dry.
5. Roots form in ~4 weeks; then remove bag and gradually increase light.

Original Plant

Check for new growth on the old stem for 3–4 weeks. If none appears, discard it. Focus on the cutting.
