Growing guide

What to do through the growing season

  1. 01

    Sow seeds

    21 Feb to 18 Apr Optional · repeat every 3 weeks

    Sow small batches around 21st February - 18th April, in shallow drills or into a large container. Keep the soil lightly moist and sow a fresh batch every 21 days for a longer picking season.

  2. 02

    Thin seedlings

    7 Mar to 9 May Dates as each sowing reaches this stage

    When seedlings are big enough to handle, thin them to the strongest plants at apart. Do it as soon as they can be handled, then water the row well so the roots settle.

  3. 03

    Protect from slugs

    7 Mar to 17 Jun Dates as each sowing reaches this stage

    Check plants from 7th March and keep the area clear of weeds and hiding places. Use barriers or pellets if needed, because young sorrel leaves can be nibbled hard in damp weather.

  4. 04

    Water regularly

    14 Mar to 10 Nov Dates as each sowing reaches this stage

    From 14th March, water whenever the top of the soil starts to dry out. Keep the bed evenly moist, as dry checks make the leaves tougher and can push plants to bolt.

  5. 05

    Harvest leaves

    18 Apr to 24 Nov Dates as each sowing reaches this stage

    Start picking from 18th April once plants are well established, then keep cutting outer leaves through 24th November. Pick little and often, and leave the centre growing so the plant keeps producing.
