Troubleshooting
Common Blanket Flower problems — and how to fix them
Common Blanket Flower (Gaillardia aristata) 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.
Crown rot
The primary cause of early plant death; caused by persistently wet soil — plant in sharply drained, lean conditions.
Short lifespan
Often lives only 2-3 years; regular division and allowing self-seeding maintains a colony in the garden.
Powdery mildew
Affects foliage in humid, warm summers; improve air circulation and avoid wetting foliage.
Aster yellows
Leafhopper-transmitted phytoplasma causes green-coloured, distorted flowers and yellowing; destroy affected plants.
Legginess
Caused by insufficient light; deadhead regularly to encourage compact re-growth and site in full sun.
