Veronica spicata 'Royal Candles' (Veronica spicata 'Royal Candles') 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.
Floppy stems
Caused by too much shade or excess nitrogen; grow in full sun and feed sparingly to keep spikes upright.
Powdery mildew
White coating in humid, crowded, or dry-stressed conditions; improve airflow, water at the base, and avoid drought stress.
