Grow mint in a pot to stop it spreading and to keep the flavour fresh. It suits a bright windowsill, patio, or sheltered spot outdoors.

  1. 01

    Sow Seeds

    3 Mar to 1 May

    Sow seed thinly on the surface of moist seed compost around 3rd March - 1st May and press it in lightly. Do not cover deeply, as mint seed needs light to get going.

  2. 02

    Pot On Seedlings

    24 Mar to 5 Jun Dates as each sowing reaches this stage

    When seedlings are large enough to handle from 24th March, prick them out into small individual pots. Keep them just moist and grow them on in a bright place.

  3. 03

    Plant Out

    21 Apr to 3 Jul

    Move plants into their final pots from 21st April, using free-draining compost and a container with good drainage holes. Water in thoroughly straight after planting and keep the compost lightly moist while roots settle.

  4. 04

    Pinch Out Tips

    21 Apr to 9 Oct Dates as each sowing reaches this stage Optional · repeat every 3 weeks

    From 21st April, pinch out the growing tips regularly to keep plants bushy and delay flowering. If stems get leggy, trim them back lightly and the plant will usually reshoot.

  5. 05

    Water and Feed

    21 Apr to 9 Oct Dates as each sowing reaches this stage Optional · repeat every 2 weeks

    Check the pot often from 21st April and water whenever the compost starts to dry at the top. A light liquid feed every 14 days helps pots keep producing fresh growth.

  6. 06

    Harvest Leaves

    5 May to 8 Nov Dates as each sowing reaches this stage Optional · repeat every 2 weeks

    Start picking from 5th May once plants are well established. Snip shoots regularly from 5th May to 8th November, taking a little and often so the plant stays leafy and does not flower too early.

Spearmint

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