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

    10 Mar to 8 May

    Sow seed thinly on the surface of seed compost around 10th March - 8th May and barely cover it. Keep the compost evenly moist while the seedlings emerge.

  2. 02

    Pot On Seedlings

    31 Mar to 12 Jun Dates as each sowing reaches this stage

    Prick seedlings out into individual pots from 31st March once they are easy to handle. Grow them on until roots fill the pot and the plants are sturdy.

  3. 03

    Harden Off

    10 Apr to 24 Apr

    From 10th 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

    28 Apr to 10 Jul

    Set plants into prepared ground from 28th 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

    28 Apr to 29 Sept Dates as each sowing reaches this stage Optional · repeat every 3 weeks

    From 28th 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

    23 Jun to 29 Sept Dates as each sowing reaches this stage Optional · repeat every 2 weeks

    Begin picking from 23rd June once the plants have bulked up. Pinch out the tips often from 23rd June to 29th September 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.
