  1. Sow Seeds Indoors

    11 Feb – 18 Feb

    Sow one seed on its edge in a small pot of warm compost around 11th February - 18th February. Keep the compost just moist and do not sow earlier, because seedlings grow fast and can become root-bound if left too long.

  2. Pot On Seedlings

    28 Feb – 14 Mar

    When the first true leaves are formed, move each seedling into a larger pot so roots have room to develop. Handle them gently and keep them in good light from 28th February to 14th March.

  3. Harden Off Plants

    4 Mar – 18 Mar

    Acclimatise plants outdoors over about 10 days from 4th March to 18th March. Start in a sheltered spot by day and bring them in at night, then leave them out longer each day until they cope with full outdoor conditions.

  4. Transplant Outdoors

    18 Mar – 1 Apr

    Plant into rich soil or a prepared mound around 18th March - 1st April once frost risk has passed. Water in thoroughly straight after planting, keep the stem base slightly raised above the surrounding soil, and space plants apart.

  5. Water and Feed

    9 May – 1 Dec
    every week

    From 9th May to 1st December, water deeply at the soil rather than over the leaves, and avoid soaking the main stem. Begin feeding with a high-potash liquid feed once the first fruits set, then repeat every 7 days while plants are cropping.

  6. Harvest Courgettes

    29 Apr – 1 Dec
    every 3 days

    Pick fruits from 29th April to 1st December while they are small and tender, ideally when they are long. Harvest often, because regular picking keeps the plant producing for longer.

Plants to avoid

Why companion planting matters

Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.
