Troubleshooting
Foxglove Sage problems — and how to fix them
Foxglove Sage (Salvia digitaliflora) 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.
Root rot from overwatering or poor drainage
Despite preferring moist conditions, roots must never sit in stagnant water; use free-draining potting compost and containers with good drainage holes, and allow excess water to drain freely after watering.
Aphids on new growth
Soft emerging shoots attract aphid infestations; check regularly under leaves and at growing tips. Treat with insecticidal soap spray or neem oil, and encourage beneficial insects such as ladybirds.
