What to do through the growing season

Change the guide to see different planting timelines and tips.

Sow an outdoor variety indoors, harden it off, then plant into a warm, sheltered bed.

  1. 01

    Sow Seeds Indoors

    15 May to 22 May

    Sow seeds on their edge to a depth of in modules from 15th May - 22nd May. Keep them at on a warm windowsill or in a propagator. Sow no earlier than this to avoid leggy, root-bound seedlings.

  2. 02

    Harden Off Seedlings

    29 May to 12 Jun

    Gradually acclimatise seedlings to outdoor conditions over 15 days from 29th May - 12th June. Place them outside in a sheltered spot during the day, bringing them in at night. This toughens them up before transplanting.

  3. 03

    Transplant Outdoors

    12 Jun to 26 Jun

    Plant into a warm, sunny bed around 12th June - 26th June, but wait until local temperatures stay above . Space plants apart, water them in and protect them if a cold spell returns.

  4. 04

    Let Plants Sprawl

    19 Jun to 10 Jul Dates as each sowing reaches this stage

    Allow plants to spread naturally across the ground or over a low frame. Do not pinch out flowers, as outdoor varieties need bee pollination to set fruit. Mulch around plants to suppress weeds and retain moisture.

  5. 05

    Water and Feed Regularly

    12 Jun to 17 Oct Dates as each sowing reaches this stage Optional · repeat every 2 weeks

    Keep the soil moist from 12th June, watering at the base in dry weather. Feed container plants every 14 days once flowering starts, switching to a high-potassium liquid fertiliser.

  6. 06

    Harvest Cucumbers

    11 Aug to 17 Oct Dates as each sowing reaches this stage

    Pick fruits regularly when they reach a usable size from 11th August - 17th October. Cut them from the vine with a knife, harvesting every few days to encourage continuous production. Outdoor varieties may have a shorter season, so pick promptly.
