Appalachian Blazing Star problems — and how to fix them
Appalachian Blazing Star (Liatris squarrulosa) 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 and crown rot
Pythium and Fusarium species cause rapid collapse of the corm in heavy or waterlogged soils, particularly over winter; always plant on a slight slope or raised bed to promote runoff, and never mulch heavily over the crown.
Stem lodging
Tall plants in rich soils or partial shade can become top-heavy and topple; stake with cane supports early in the season, or site plants where neighbouring plants provide mutual support.
