Growing guide

Step-by-step instructions for growing Strawflower

  1. 01

    Sow Seeds Indoors

    27 Mar to 20 Apr

    Sow seeds in modules or trays around 27th March - 20th April at a depth of . Keep them at and just moist until they germinate, then give them plenty of light so the seedlings do not stretch.

  2. 02

    Prick Out Seedlings

    29 Apr to 13 May

    When the seedlings are large enough to handle, prick them out into individual pots around 29th April - 13th May. Handle them by the leaves, not the stems, and keep them growing on in bright, frost-free conditions.

  3. 03

    Harden Off

    27 Apr to 11 May

    Acclimatise the young plants gradually around 27th April - 11th May. Put them outside for a few hours at first, then extend the time over about a week so they get used to sun and wind.

  4. 04

    Transplant Outdoors

    25 May to 8 Jun

    Plant out around 25th May - 8th June once frosts have passed and the soil has warmed. Space plants apart in full sun, and water in thoroughly straight away.

  5. 05

    Support and Feed

    1 Jul to 17 Oct every 2 weeks

    Check plants from 1st July as they settle in, and keep the soil evenly moist in dry spells. A light liquid feed every 14 days helps maintain growth without making the plants soft and floppy.

  6. 06

    Deadheading & Maintenance

    1 Jul to 17 Oct

    From 1st July onwards, deadhead fading flowers regularly by cutting stems back to a leaf joint. This stops the plant setting seed and keeps it flowering well until the autumn frosts.
