Growing guide

Step-by-step instructions for growing Watercress

  1. 01

    Sow Seeds

    3 Apr to 15 May every 3 weeks

    Sow seeds around 3rd April - 15th May on the surface of very moist compost, then press them in lightly rather than burying them. Keep the compost constantly damp while they germinate, and sow a fresh batch every 21 days for a steady supply.

  2. 02

    Thin Seedlings

    22 May to 29 May

    When seedlings are large enough to handle, from 22nd May, thin them so the strongest plants have room to spread. Keep the soil wet at all times, because even brief drying checks growth.

  3. 03

    Transplant

    24 Apr to 5 Jun

    Move seedlings to their final spot around 24th April - 5th June, spacing them well apart in mud-like soil or a shallow run of water. Water in thoroughly straight after planting and keep the roots submerged or constantly wet.

  4. 04

    Feed Plants

    15 May to 18 Oct every 2 weeks

    From 15th May, give a very light liquid feed every 14 days if growth slows, but avoid strong feeding that makes the leaves coarse. Keep the bed weed-free and topped up with water.

  5. 05

    Harvest Leaves

    12 Jun to 4 Dec

    Start cutting from 12th June when plants are well rooted and the shoots are leafy. Pick little and often through to 4th December, taking the outer stems first and leaving the centre to regrow.

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.
