Echinops ritro 'Veitch's Blue' problems — and how to fix them
Echinops ritro 'Veitch's Blue' (Echinops ritro 'Veitch's Blue') 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.
Lax stems in shade or rich soil
Shade and fertile ground produce floppy growth and weaken the blue colour. Plant in full sun on lean, free-draining soil to keep it upright and richly coloured.
Winter crown rot
Wet, heavy soil rots the deep taproot over winter. Sharpen drainage with grit and avoid waterlogged or low-lying spots.
Powdery mildew
Dry roots and crowded, humid foliage encourage mildew. Allow generous spacing for airflow and avoid wetting the leaves late in the day.
Aphid infestation
Aphids cluster on buds and stems and can distort growth. Hose them off or leave them, since the flowers draw plentiful beneficial insects.
