Plant mint in a contained bed or sunk pot if you want it in the soil. It spreads by runners, so containment is the main job.

  1. 01

    Sow Seeds

    2 Mar to 30 Apr

    Sow seed thinly on the surface of seed compost around 2nd March - 30th April and barely cover it. Keep the compost evenly moist while the seedlings emerge.

  2. 02

    Pot On Seedlings

    23 Mar to 4 Jun Dates as each sowing reaches this stage

    Prick seedlings out into individual pots from 23rd March once they are easy to handle. Grow them on until roots fill the pot and the plants are sturdy.

  3. 03

    Harden Off

    2 Apr to 16 Apr

    From 2nd April, acclimatise plants outside over about 10 days before planting them out. Keep them out of cold wind and bring them in if a late cold spell is forecast.

  4. 04

    Plant Out

    20 Apr to 2 Jul

    Set plants into prepared ground from 20th April, spacing them so air can move around the clump. Water in thoroughly straight after planting and keep them watered until they are properly rooted.

  5. 05

    Contain Spread

    20 Apr to 13 Oct Dates as each sowing reaches this stage Optional · repeat every 3 weeks

    From 20th April, check for runners and cut them back before they root beyond the allotted space. Regular containment keeps ground-grown mint tidy and stops it taking over.

  6. 06

    Pinch And Harvest

    15 Jun to 13 Oct Dates as each sowing reaches this stage Optional · repeat every 2 weeks

    Begin picking from 15th June once the plants have bulked up. Pinch out the tips often from 15th June to 13th October and harvest regularly to keep fresh growth coming.

Suggested varieties

Popular varieties of Mint to consider

Spearmint

A classic, sweet mint for tea, sauces, and salads. It is a strong grower and a good choice for pots.

Peppermint

Chocolate Mint

A milder mint with a hint of cocoa in the scent. It spreads just as freely as other mints, so keep it contained.
