Echinacea 'Pink Double Delight' problems — and how to fix them
Echinacea 'Pink Double Delight' (Echinacea purpurea 'Pink Double Delight') 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.
Aster yellows
Causes distorted, pale green flowers and stunted growth. Spread by leafhoppers; no cure — remove and destroy affected plants promptly.
Powdery mildew
White coating on lower leaves in humid or crowded conditions. Improve spacing and airflow; apply sulphur spray at early onset.
Japanese beetle damage
Adults skeletonise petals and foliage. Hand-pick in the morning; avoid pheromone traps, which attract more beetles than they catch.
Botrytis on double blooms
Fully double forms are more prone to petal mould in wet weather due to dense petal layering. Deadhead promptly and avoid overhead watering.
Short lifespan in heavy soil
Double cultivars can be shorter-lived than species. Divide clumps every 3-4 years and ensure drainage to extend plant life.
