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

    23 Mar to 21 May

    Sow seed thinly on the surface of moist seed compost around 23rd March - 21st May and press it in lightly. Do not cover deeply, as mint seed needs light to get going.

  2. 02

    Pot On Seedlings

    13 Apr to 25 Jun Dates as each sowing reaches this stage

    When seedlings are large enough to handle from 13th April, prick them out into small individual pots. Keep them just moist and grow them on in a bright place.

  3. 03

    Plant Out

    11 May to 23 Jul

    Move plants into their final pots from 11th May, 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

    11 May to 19 Sept Dates as each sowing reaches this stage Optional · repeat every 3 weeks

    From 11th May, 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

    11 May to 19 Sept Dates as each sowing reaches this stage Optional · repeat every 2 weeks

    Check the pot often from 11th May 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

    25 May to 19 Oct Dates as each sowing reaches this stage Optional · repeat every 2 weeks

    Start picking from 25th May once plants are well established. Snip shoots regularly from 25th May to 19th October, taking a little and often so the plant stays leafy and does not flower too early.
