Cardinal Flower Sinningia problems — and how to fix them
Cardinal Flower Sinningia (Sinningia cardinalis) 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.
Leaf spotting from wet foliage
Cold water or droplets left on the velvety leaves cause pale rings and brown blotches. Water at the soil line and keep foliage dry.
Tuber rot
Overwatering or a heavy, poorly draining mix rots the tuber. Let the surface dry between waterings and cut water back hard during dormancy.
Few or no flowers
Too little light or skipped feeding limits blooming. Move to bright indirect light and feed a bloom formula in the growing season.
Sudden leaf drop / dormancy confusion
Shorter days and cooler temperatures trigger natural winter dormancy. Don't assume the plant is dead; rest the tuber dry-ish and growth returns in spring.
