Veronica longifolia 'Blauriesin' problems — and how to fix them
Veronica longifolia 'Blauriesin' (Veronica longifolia 'Blauriesin') 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
A common issue on Veronica, worsened by drought stress and poor airflow. Keep soil moist, space plants and remove affected leaves.
Flopping stems
Rich soil, shade or rain can splay the clump. Grow in full sun, avoid over-feeding, and ring-stake heavy clumps if needed.

Spent spikes slow rebloom. Cut back faded flowers promptly to encourage a second flush.
Root or crown rot
Caused by waterlogged winter soil. Plant in free-draining ground and improve heavy clay with grit and organic matter.
