Troubleshooting
Snowdrop Windflower problems — and how to fix them
Snowdrop Windflower (Anemone sylvestris) 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.
Summer dormancy
Foliage yellows and dies back in midsummer — this is normal; mark the position to avoid accidentally disturbing dormant rhizomes.
Slugs
Tender spring foliage and flowers are eaten by slugs; use organic pellets or nematodes in damp spring weather.
Powdery mildew
May occur in dry summers if plants are in more exposed positions; rarely serious and usually prevented by adequate moisture and shade.
Restricted spread
In very dry or compacted soils the plant spreads slowly; improve soil structure and moisture retention to encourage colonisation.
