Troubleshooting
Mountain Everlasting problems — and how to fix them
Mountain Everlasting (Antennaria dioica) 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.
Crown rot
The leading cause of death. Caused by overwatering or poorly drained soil, especially in winter. Ensure gritty, free-draining substrate and reduce watering to almost nothing when dormant.
Aphid infestation
Woolly stems attract woolly aphids and root aphids in warm, humid summers. Inspect the undersides of leaves and crown regularly; treat with insecticidal soap or neem oil at first sign.
Loss of mat density in shade
In less than 5–6 hours direct sun, plants become leggy and rosettes spread apart, losing the tight mat form. Relocate to a sunnier position or use as a companion on south-facing slopes.
