Diagnosing Problems with Florida Flame Azalea
| Symptom | Likely cause | Confirming sign | Action |
|---|---|---|---|
| Leaves yellowing unevenly across the plant | Uneven watering or compacted soil | Yellowing worse on one side; soil hard or crusted at surface | Water Florida Flame Azalea deeply and evenly. Loosen surface compaction with a fork; avoid disturbing main roots. |
| Sudden wilting on one branch while rest of plant looks healthy | Root rot from poor drainage in one spot | Affected branch has dark, mushy roots when gently uncovered | Cut back affected branch to healthy wood. Improve drainage in that area before the next growing season. |
| Dieback of branch tips after winter | Frost damage or wind scorch | Damage consistent across exposed side; wood brown inside tip | Prune Florida Flame Azalea back to healthy green wood in late spring once growth resumes. Do not prune earlier — wait to confirm what has survived. |
