PowWow Wild Berry coneflower problems — and how to fix them
PowWow Wild Berry coneflower (Echinacea purpurea 'PowWow Wild Berry') 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.
Powdery mildew
Greyish-white coating on leaves in warm, humid or dry conditions. Water at the base to keep foliage dry, space plants for airflow. Fungal sprays are rarely needed; remove and dispose of badly affected leaves.
Crown rot
Caused by waterlogged or poorly draining soil, especially in winter. Plant in raised beds or amended soil; do not mulch over the crown. Most common in container culture with insufficient drainage holes.
Aster yellows phytoplasma
Causes distorted, pale, strap-like petals and a witches'-broom appearance. Spread by leafhoppers; no cure. Remove and destroy affected plants promptly to prevent spread.
