Jerusalem Artichoke 'Red Fuseau' problems — and how to fix them
Jerusalem Artichoke 'Red Fuseau' (Helianthus tuberosus 'Red Fuseau') 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.
Invasive spread
Any tuber fragment left in the ground regrows, so it readily becomes a permanent colony. Confine to a dedicated bed and lift thoroughly each year.
Wind rock and lodging
Tall stems topple in exposed sites. Stake, plant in a sheltered spot, or pinch out tops in midsummer to limit height.
Sclerotinia rot
Stored or in-ground tubers can develop white fungal rot in wet conditions. Improve drainage and rotate the planting site.
Inulin-related flatulence
Not a plant fault but a use issue; the high inulin content causes gas in people and pets. Harvesting after frost and slow cooking eases it.
