How to grow spearmint in pots or window boxes


Spearmint (Mentha viridis) is a herbaceous herb (aromatic plant). It is a species of Mint. It is one of the easiest herbs to grow.

You can sow spearmint seeds in early spring, after the last frosts. Use a lot of seeds because many of them are sterile.

Spread the spearmint seeds over the soil and water immediately. Do not cover the seeds with soil. Place the pot or window box where the sun will see it. The seeds will germinate in about 12 days.

To help the seeds germinate, you can cover the pot with a transparent plastic, e.g. wrapping film. This will create a draft greenhouse effect.

Another common way of propagation is by using rhizomes. You can transplant spearmint rhizomes from a grown plant into a new pot or window box.

Spearmint needs sun to grow, but it can tolerate a place where it gets a few hours of sunlight a day.

Spearmint needs to be watered regularly because it is water demanding.

Greek name: Δυόσμος.
