What to inspect
Build a seven-to-fourteen-day timeline of moves, cold nights, watering, standing water, pests, and which leaves dropped first.
Choose one evidence-based action
Stabilize the clearest environmental change and inspect roots only when moisture evidence supports it. Judge recovery by retained and new leaves.
What not to do
Do not diagnose leaf drop from one mark, change several major conditions at once, or use an unlabeled treatment. Old damage may remain after the cause is corrected.
Review the outcome
Photograph the same area under similar light, record the date and intervention, then compare the boundary of damage and the quality of new growth. Escalate rapid decline or safety concerns to an appropriate professional.
