Troubleshooting
Alpine Toadflax problems — and how to fix them
Alpine Toadflax (Linaria alpina) 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.
Damping-off of seedlings
Young self-sown seedlings are prone to fungal damping-off in heavy or poorly drained substrates. Ensure very gritty soil and avoid overwatering around seedlings; a fine grit mulch helps prevent soil-splash infection.
Short lifespan / premature death
This is naturally a short-lived perennial or biennial that may die after 2–3 years; this is normal behaviour, not disease. Allow it to set seed each year so that new plants replace the parent naturally.
