Heath Speedwell problems — and how to fix them
Heath Speedwell (Veronica officinalis) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Leaf spots (Septoria and Ramularia)
Small brown or pale leaf spots caused by fungal pathogens appear in wet seasons or when plants are overcrowded; improve airflow, remove affected foliage, and avoid overhead watering.
Slugs on young spring growth
Slugs and snails graze the soft new foliage and stem tips in spring; use iron phosphate slug pellets or copper barriers around vulnerable young plants.
