Growing notes
- Oregano prefers neutral to slightly alkaline soil and is intolerant of acid, soggy mixes.
- A 6"-deep container will work, but a wider pot lets the spreading habit fill in.
- Cut back hard after flowering to keep the plant from going woody and to spur fresh foliage.
- Greek oregano (O. vulgare subsp. hirtum) has stronger flavor than ornamental forms.
- Container plants need supplemental watering more than in-ground plants — check soil weekly.
