Growing guide

What to do through the growing season

  1. 01

    Sow Seeds Indoors

    25 Mar to 18 Apr

    Sow seeds into modules from 25th March to 18th 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

    8 Apr to 16 May Dates as each sowing reaches this stage

    When seedlings are large enough to handle, move them on from 8th April to 16th May into small pots. Handle them by the leaves, not the stems, and keep them growing on in good light.

  3. 03

    Harden Off

    9 May to 6 Jun Dates as each sowing reaches this stage

    Acclimatise the young plants through 9th May - 6th June 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

    23 May to 6 Jun

    Plant out from 23rd May to 6th June 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

    22 Jun to 9 Oct Dates as each sowing reaches this stage

    Start deadheading from 22nd June and keep going until 9th 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.
