  1. Sow Seeds Indoors

    25 Feb – 21 Mar
    every 3 weeks

    Sow seeds into modules around 25th February - 21st March in a fine seed compost, covering them with of compost. Keep them at and just moist, then prick out the seedlings once they are large enough to handle.

  2. Pot On Seedlings

    23 Mar – 6 Apr

    Move seedlings on when roots fill the module, keeping them growing steadily before planting out. Handle them by the leaves, not the stems, and keep them in bright light so they do not get leggy.

  3. Harden Off

    11 Apr – 25 Apr

    Acclimatise plants over 7 to 10 days before planting out, giving them short spells outdoors in a sheltered spot. Keep them protected from cold nights and hard rain until they are ready for the border or container.

  4. Transplant as Companion Plants

    25 Apr – 9 May

    Plant them out around 25th April - 9th May into a sunny, free-draining position, spacing them apart. Water in thoroughly straight away, then grow them near tomatoes to help deter whitefly and add a useful flowering strip among crops.

  5. Deadhead & Maintain

    1 Jun – 12 Oct

    From 1st June onwards, remove faded flowers regularly so the plant keeps producing new blooms instead of setting seed. Water during dry spells and keep checking through 12th October for the best display right up to the autumn frosts.
