Sanguine Coneflower problems — and how to fix them
Sanguine Coneflower (Echinacea sanguinea) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crown and root rot
The single most common failure in cultivation; planting in clay or poorly drained soil — or any soil that differs significantly from its native acidic sand — leads to Pythium or Fusarium rot at the crown; site selection is the only preventive.
Japanese beetle feeding
Adults skeletonise foliage and chew ray petals from early to midsummer; hand-pick adults in early morning and drop into soapy water; avoid using pheromone traps near the planting as they attract far more beetles than they catch.
