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

    Sow Seeds

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

    Sow thinly around mid-April to early May, on the surface of prepared soil and just press them in. Keep the row evenly moist while seedlings establish, and thin them later so the strongest plants have room to grow.

  2. 02

    Thin Seedlings

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

    When seedlings are large enough to handle, thin them to the final spacing so the plants do not become crowded. Move carefully, because gypsophila dislikes root disturbance.

  3. 03

    Plant Out

    late May to early July UK average · set your town for your exact dates

    Set young plants into their final position once they are sturdy and well rooted, from late May. Water in thoroughly straight after planting, and use a short cane or support if the site is exposed.

  4. 04

    Support and Care

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

    From late May, keep plants watered in dry spells and protect the stems from wind in open sites. Avoid rich feeding, because too much nitrogen gives soft growth and fewer flowers.

  5. 05

    Cut and Deadhead

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

    Start cutting from late June as soon as the first stems open, then keep removing faded sprays to prolong flowering. Pick stems regularly and leave some foliage in place so the plant can keep producing through late October.

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.
