Growing guide

What to do through the growing season

  1. 01

    Sow Seeds Indoors

    3 Apr to 17 Apr

    Sow seeds into individual modules around 3rd April - 17th April. Cover with of compost and keep the compost just moist while seedlings emerge.

  2. 02

    Pot On Seedlings

    17 Apr to 15 May Dates as each sowing reaches this stage

    When seedlings have a couple of true leaves, from 17th April to 15th May, move them into individual pots if their modules are crowded. Handle them by the leaves, not the stems, and keep them in bright light so they do not become leggy.

  3. 03

    Harden Off

    1 May to 22 May Dates as each sowing reaches this stage

    From 1st May to 22nd May, move plants outside for longer each day before planting them out. Protect them from cold nights and strong wind, and keep them in a sheltered spot at first.

  4. 04

    Plant Out

    15 May to 29 May

    Once the soil has warmed and frost risk has passed, plant out your hardened-off seedlings around 15th May - 29th May. Space them apart, water in thoroughly straight after planting, and give them a sunny spot with free-draining soil.

  5. 05

    Deadheading and Maintenance

    14 Jun to 17 Oct Dates as each sowing reaches this stage

    From 14th June to 17th October, remove fading flowers regularly so the plant keeps producing new blooms instead of setting seed. Water only in dry spells, because rich soil and heavy feeding usually mean more leaves and fewer flowers.

  6. 06

    Harvest Flowers And Leaves

    14 Jun to 17 Oct Dates as each sowing reaches this stage

    Pick flowers and young leaves from 14th June until 17th October. Harvest in the morning for the best flavour, and take only a few leaves from each plant so it keeps flowering well.
