Troubleshooting
Creeping Speedwell problems — and how to fix them
Creeping Speedwell (Veronica repens) 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
Common in hot, humid or poorly ventilated conditions. Improve air circulation, avoid overhead watering, and apply a sulfur-based fungicide if severe.
Root rot
Caused by waterlogged or heavy soils. Ensure excellent drainage and reduce irrigation frequency during cool or wet weather.
Slugs and snails
The dense mat of foliage provides shelter for slugs, which rasp holes in leaves. Use iron phosphate pellets or copper tape barriers around planting areas.
