Growing guide

What to do through the growing season

Dates for your town

Set your town to see planting windows worked out from local frost history, not a generic UK calendar.

  1. 01

    Plant Out

    mid-May to late May UK average · set your town for your exact dates

    Plant rooted plants or cuttings around mid-May to late May in fertile, free-draining soil. Set them at the same depth they were growing before, then water in thoroughly straight away.

  2. 02

    Water Until Established

    early May to mid-July UK average · set your town for your exact dates Dates as each sowing reaches this stage

    Keep the soil evenly moist from early May while new roots form. Water at the base in dry spells and avoid wetting the leaves, especially in damp weather.

  3. 03

    Feed and Deadhead

    mid-June to late October UK average · set your town for your exact dates Optional · repeat every 2 weeks

    From mid-June through late October, feed every 14 days with a high-potash liquid feed and remove faded blooms as they fade. Pinch or cut off spent flowers back to a leaf joint so the plant keeps flowering for longer.

  4. 04

    Tie In Tall Stems

    late May to late September UK average · set your town for your exact dates Dates as each sowing reaches this stage

    Check plants from late May and stake or tie in taller stems before they flop in wind and rain. Use soft ties and keep the plant open so air can move through it.

  5. 05

    Cut Back Growth

    late October to late November UK average · set your town for your exact dates

    After flowering finishes around late October to late November, cut stems back to a low framework once frost has blackened the top growth. Leave the crown in place if you want the plant to overwinter.

Why companion planting matters

Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.
