How to plant it

General steps for this plant. Save a garden and these become specific to your location, soil and light.

  1. Step 1When to plant

    Plant during March to May, once the risk of frost has passed.

    Timing depends on your last frost date.

  2. Step 2Where to put it

    Choose a position with a few hours of direct sun and shade for the rest of the day. Allow 0.6 m of room around it — mature spread is 0.6 m and mature height 0.3–0.6 m.

    Light in your garden is not answered, so this is the plant's own requirement.

  3. Step 3Preparing the ground

    Dig a hole twice as wide as the root ball and no deeper, loosen the sides, and plant so the top of the root ball is level with the surrounding soil.

    Soil is not answered. This plant grows in average, moisture-retentive conditions.

  4. Step 4Watering while it establishes

    Water thoroughly at planting (5–10 litres), then only when the top few centimetres of soil are dry, through the first growing season.

    Even a drought-tolerant plant (2/5 here) only becomes drought-tolerant once established.

  5. Step 5Mulch

    Spread 5–7 cm of composted bark or garden compost around the plant, keeping it clear of the stem.

    Mulch cuts water loss and suppresses weeds through the first summer, when losses are most likely.

  6. Step 6The first year

    Check it after strong wind and in long dry spells. Little else is needed.

    Maintenance level on the plant record is low.

  7. Step 7What to watch for

    Invades beds; always grow in a pot.

Spacing: about 0.6 m apart — roughly 28 plants for every 10 m² if planted as a group.

What this guide could not use

  • No location saved, so planting times are general rather than local.
  • Soil moisture is not answered, so soil preparation is general advice.
  • Light is not answered, so the position below is the plant's own preference.
  • Whether you can water is not answered, so watering assumes hand watering.

Spearmint (Mentha spicata), also known as garden mint, common mint, lamb mint and mackerel mint, is native to Europe and southern temperate Asia, extending from Ireland in the west to southern China in the east. It is naturalized in many other temperate parts of the world, including northern and southern Africa, North America, and South America. It is used as a flavouring in food and herbal teas. The aromatic oil, called oil of spearmint, is also used as a flavoring and sometimes as a scent. The species and its subspecies have many synonyms, including Mentha crispa, Mentha crispata, and Mentha viridis.

These figures come from the demonstration dataset kept for testing and as a fallback when the measured climate service is unavailable. They are representative, not observed, and are never presented as validated live data.
