Troubleshooting
Scaly Blazing Star problems — and how to fix them
Scaly Blazing Star (Liatris squarrosa) 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.
Corm rot in wet soil
The most common cause of failure; soggy or heavy soil rots the corm. Plant only in sharply drained, sandy or gravelly ground.
Poor bloom in shade or rich soil
Shade and fertility cause weak stems and few flowers. Grow in full sun on lean soil for compact, floriferous plants.
Rodent damage to corms
Voles and mice may dig the corms in winter. Use a gravel mulch or wire basket to protect plantings.
Slow establishment from seed
Seedlings need 2-3 years to reach flowering size. Be patient and avoid disturbing the developing corm.
