About Oregano
Oregano (Origanum vulgare) is an easy, productive Mediterranean herb that thrives in bright light and lean, well-drained soil. It grows wild across the hills of southern Europe and western Asia. For a renter it suits a 3-litre pot in a sunny window, and once established it spreads and regrows hard after cutting. One plant gives generous leaf through the season.
Like its Mediterranean relatives, oregano prefers things on the drier side, so let the soil dry between waterings. Pinch and harvest often to keep it bushy rather than leggy, and give it strong light, where the flavour is most intense just before flowering. A first harvest comes around 50 to 80 days. It roots easily from soft stem cuttings, and mature clumps can be divided if you want more plants.
What it’s like to grow
Oregano is easy and vigorous, a reliable choice for a bright sill. With its low water needs, soggy or poorly drained pots are the main hazard and can cause root rot. Leggy, sprawling growth is its signal for more light. Frequent harvesting keeps it compact and productive. One important caution: oregano is listed as toxic to cats and dogs, so keep it somewhere animals can't graze on the leaves.
What to expect
First harvest in about 50–80 days. It’s forgiving, so it’s a good one to learn on. No sunny window? It also does fine under a clip-on grow light.

Common questions
Is Oregano toxic to cats and dogs?
Oregano is toxic to cats and dogs if eaten, so keep it out of reach of pets that chew. Source: ASPCA.
How much light does Oregano need?
Oregano wants bright light — a south-facing window with six or more hours of sun, or a grow light to make up for it.
How often should I water Oregano?
Water Oregano sparingly. Let the soil dry out fully between waterings — it's far more likely to rot from overwatering than to suffer from neglect.
What temperature does Oregano need?
Oregano is happiest around 15–27 °C. It tolerates brief dips to about -12 °C, but cold drafts and sudden chills set it back.
How long does Oregano take to grow?
Expect a first harvest about 50–80 days from sowing under good conditions. A spreading, vigorous herb that gives generous leaf once established and regrows hard after cutting.
Can I grow Oregano without a sunny window?
Yes. Oregano does well under an affordable clip-on grow light, so a bright window isn't essential.
How big does Oregano get?
A low spreading herb ~0.2–0.3 m tall and wide; one plant per small pot.
How do I propagate Oregano?
Root a soft stem cutting in water or soil; mature clumps can also be divided.
What pests affect Oregano?
Watch for aphids, spider mites and whitefly. Check new growth and the undersides of leaves often, and treat early with a rinse or insecticidal soap before they spread.
Is Oregano easy to grow?
Yes. Oregano is forgiving and one of the better plants to learn on.
