Troubleshooting
Greek Oregano problems — and how to fix them
Greek Oregano (Origanum vulgare subsp. hirtum) 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.
Loss of flavour
Too little sun or over-rich, over-watered soil produces bland leaves; grow hard in full sun and lean soil to concentrate the oils.
Root rot
Heavy or waterlogged soil rots the roots; improve drainage with grit and let the soil dry between waterings.
Woody, sparse base
Plants go woody and unproductive with age; cut back hard after flowering and replace or divide every 3-4 years.
Powdery mildew
A white coating in humid, crowded conditions; thin growth for airflow and avoid overhead watering.
