Mouse-ear Hawkweed problems — and how to fix them
Mouse-ear Hawkweed (Pilosella officinarum) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot
The most common problem; caused by poor drainage or overwatering — plant only in very free-draining soil and reduce watering immediately at the first sign of wilting or yellowing basal leaves.
Invasive spreading via stolons
Spreads aggressively into lawns and adjacent plantings via surface stolons; remove stolons regularly or install a root barrier if growing in a formal border.
