Eryngium planum 'Blue Hobbit' problems — and how to fix them
Eryngium planum 'Blue Hobbit' (Eryngium planum 'Blue Hobbit') 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.
Taproot rot in wet soil
Heavy, rich or poorly drained ground rots the deep taproot, especially over winter. Grow on sharply drained, gritty soil and avoid soggy positions.
Floppy growth in shade or rich soil
Too little sun or over-feeding produces lax stems and weak colour. Plant in full sun on lean soil to maintain the tight, dwarf habit.
Resents transplanting
The long taproot makes established plants difficult to move and slow to recover. Plant young, in the final position, and avoid disturbing mature clumps.
Powdery mildew
Crowded, humid conditions or dry roots can bring mildew to the foliage. Space plants for airflow and water at the base rather than overhead.
