Troubleshooting
Dotted Blazing Star problems — and how to fix them
Dotted Blazing Star (Liatris punctata) 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.
Transplant difficulty
The deep taproot makes established plants very difficult to transplant without breakage. Sow seed or plant young container-grown plants; avoid moving mature specimens.
Corm and root rot
Heavy clay or irrigated soils cause root and crown rot. This species is particularly unforgiving of wet conditions. Plant exclusively in sharply drained, dry soil.
Stem borers
Liatris stem borers (Carmenta anthracipennis) can tunnel into stems, causing wilting and lodging. Cut and destroy affected stems. Broad pesticide use is discouraged given the plant's pollinator value.
