Troubleshooting
Greek Mountain Tea problems — and how to fix them
Greek Mountain Tea (Sideritis syriaca) 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.
Root rot from overwatering
The most common cause of death; the felted, dry-adapted roots rot in wet or poorly drained soil, especially over winter. Plant in gritty, sharply drained ground and water sparingly.
Winter wet and cold damage
Only borderline hardy and intolerant of cold, sodden soil; grow in raised, sheltered, free-draining spots or overwinter under cover in colder regions.
Loss of silvering in shade or rich soil
Foliage greens up and grows lax in low light or fertile ground; keep it sunny and lean to preserve the woolly grey character.
Humidity-related fungal spotting
Felted leaves trap moisture in humid, still air, inviting fungal disease; ensure generous spacing and good airflow.
