Cat's-ear problems — and how to fix them
Cat's-ear (Hypochaeris radicata) 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.
Persistent taproot making removal difficult
The deep taproot regrows if broken — use a long-handled weeding tool to extract the full root; repeated removal over two or more seasons is usually needed to eliminate plants from lawns.
Powdery mildew in late summer
White powdery coating can appear on leaves during dry summers; usually cosmetic on a wildflower plant, but improve air circulation if growing as an ornamental and avoid overhead watering.
