Growing guide

What to do through the growing season

  1. 01

    Sow Seeds Indoors

    8 Mar to 1 Apr

    Sow seeds into modules from 8th March to 1st April, covering them with a light seed sowing depth of . Keep the compost just moist and place the tray somewhere bright and cool for steady germination.

  2. 02

    Prick Out Seedlings

    22 Mar to 29 Apr Dates as each sowing reaches this stage

    When seedlings are large enough to handle, move them on from 22nd March to 29th April into small pots. Handle them by the leaves, not the stems, and keep them growing on in good light.

  3. 03

    Harden Off

    22 Apr to 20 May Dates as each sowing reaches this stage

    Acclimatise the young plants through 22nd April - 20th May by putting them outside for longer each day. This avoids a check to growth when they go into the border and prepares them for cooler UK nights.

  4. 04

    Transplant Outdoors

    6 May to 20 May

    Plant out from 6th May to 20th May once frosts have passed and the soil has warmed a little. Space plants apart, water them in thoroughly straight away, and protect them from slugs and strong winds while they settle.

  5. 05

    Deadheading & Maintenance

    5 Jun to 28 Oct Dates as each sowing reaches this stage

    Start deadheading from 5th June and keep going until 28th October. Remove fading flowers regularly so the plant puts its energy into more blooms instead of setting seed, and keep the soil evenly moist in dry spells.
