Troubleshooting
Nicotiana sylvestris problems — and how to fix them
Nicotiana sylvestris (Nicotiana sylvestris) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Wilting large leaves
The big foliage loses water fast and droops in heat or dry soil. Keep soil moist, mulch heavily, and site out of harsh midday sun and drying wind.
Wind damage and toppling
Tall stems and broad leaves catch wind and can snap or lean. Plant in a sheltered spot and stake the flower stem in exposed gardens.
Aphids and tobacco hornworm
Aphids mass on stems while hornworms strip leaves. Wash off aphids with water or soap and hand-pick the large caterpillars from foliage.
Powdery mildew on lower leaves
Crowded, shaded, damp growth invites mildew. Improve airflow, remove affected lower leaves, and avoid overhead watering late in the day.
