Troubleshooting
Velvet Queen sunflower problems — and how to fix them
Velvet Queen sunflower (Helianthus annuus 'Velvet Queen') 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.
Stem lodging / windrock
Tall stems topple in exposed gardens or after heavy rain. Stake plants early with a bamboo cane and soft ties; plant in a wind-sheltered position or close to a fence.
Powdery mildew
Greyish-white coating on older leaves, most common late in the season. Improve spacing and airflow; remove and dispose of affected leaves. Sulphur spray can slow spread.
Squirrel and bird seed predation
Seeds are attractive to wildlife before harvest. Use fine mesh netting over developing heads if seeds are needed; for pollinator value, leave heads in situ through autumn.
