Troubleshooting
Torenia fournieri problems — and how to fix them
Torenia fournieri (Torenia fournieri) 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 in heat and drought
Flowering stalls and leaves droop if the soil dries or sun is too intense. Keep soil evenly moist and give afternoon shade in hot regions.
Powdery mildew
Crowded, damp foliage in humid weather invites mildew. Space plants for airflow, water at the base in the morning, and avoid wetting the leaves.
Root rot and damping-off
Soggy, poorly drained soil rots roots and kills seedlings. Use well-draining mix and let the surface dry slightly between waterings.
Leggy, sparse growth
Insufficient light or skipped feeding produces stretched stems and few flowers. Pinch young plants to encourage branching and feed regularly.
