Growing guide

What to do through the growing season

  1. 01

    Sow Seeds

    23 May to 11 Jul

    Sow in trays around 23rd May - 11th July. Press seed onto the surface and leave it uncovered. Keep just moist. Wear gloves. Wash your hands. All parts are toxic if eaten, including for pets.

    • A spare seedbed works if you have no trays.

  2. 02

    Thin Seedlings

    13 Jun to 22 Aug Dates as each sowing reaches this stage

    When seedlings are large enough to handle, from 13th June - 22nd August, prick them into pots, or thin a seedbed so the strongest have room.

  3. 03

    Transplant Young Plants

    26 Jul to 29 Sept

    Move sturdy rosettes around 26th July - 29th September. Space apart in moist, free-draining soil with some shade. Water in. Wear gloves.

  4. 04

    Protect and Grow On

    26 Jul to 28 Nov Dates as each sowing reaches this stage

    From 26th July, protect seedlings and new rosettes from slugs. Water in dry spells.

  5. 05

    Flower and Deadhead

    23 May to 9 Sept 2027 Dates as each sowing reaches this stage

    Spikes open next summer, from 23rd May 2027 through 9th September 2027. They will not flower in the year you sow. Deadhead spent spikes to keep the display going. Leave a few if you want self-sown plants later.

Plants to avoid

Why companion planting matters
