Troubleshooting
Veronica spicata subsp. incana problems — and how to fix them
Veronica spicata subsp. incana (Veronica spicata subsp. incana) 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.
Crown and root rot
Wet, heavy or rich soil rots the woolly crown. Plant in sharply drained ground, avoid overwatering, and never let it sit in winter wet.
Floppy, green growth
Shade or over-feeding causes the foliage to green up and the spikes to flop. Move to full sun and stop fertilising.
Downy and powdery mildew
Humid, crowded plantings develop foliar mildews. Space well, improve airflow and avoid wetting the felted leaves.
Tired clumps
Centres open up and flowering wanes after a few years. Divide in spring to rejuvenate, and shear after flowering to tidy and sometimes rebloom.
