Summer Wave Amethyst Wishbone Flower problems — and how to fix them
Summer Wave Amethyst Wishbone Flower (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.
Powdery mildew
Can appear in warm, dry spells; improve air circulation and avoid overhead watering.
Root rot
Caused by waterlogged soil; ensure containers have drainage holes and do not over-water.
Aphids
Soft new growth attracts aphids; treat with a strong water spray or insecticidal soap.
Slugs and snails
Can damage tender foliage at ground level, especially in moist shaded beds; use copper tape or iron phosphate pellets.
Leggy growth
Insufficient light causes stretching; move to a brighter (but still shaded) position and pinch tips to encourage branching.
