Troubleshooting
American Wood Anemone problems — and how to fix them
American Wood Anemone (Anemone quinquefolia) 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.
Powdery Mildew
May appear on foliage in warm, dry springs. As the plant enters dormancy shortly after flowering, late-season mildew rarely requires intervention. Improve airflow and soil moisture during the growing season.
Slugs
Emerging shoots in early spring are susceptible. Apply iron-phosphate pellets around emerging growth. Leaf-litter mulch can harbour slugs, so check around crowns regularly.
Very Slow Naturalisation
Spreads only a few centimetres per year. Plant rhizomes in groups of 10–15 at 15 cm spacing for a quicker display; propagate by division annually in late spring to build up stock more rapidly.
