Nasturtium officinale

Watercress
Fruit Active in July

Watercress is a hardy perennial leafy crop that grows best in shallow running water or very wet soil. In the UK it’s usually grown outdoors in a pond basket, streamside bed, or container kept constantly wet, and it gives the best leaves in cool weather.

  1. Sow Seeds

    1 Mar – 1 Jun
    every 3 weeks

    Sow seeds around 1st March - 1st June 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. Thin Seedlings

    30 Apr – 7 May

    When seedlings are large enough to handle, from 30th April, thin them so the strongest plants have room to spread. Keep the soil wet at all times, because even brief drying checks growth.

  3. Transplant

    17 Apr – 29 May

    Move seedlings to their final spot around 17th April - 29th May, 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. Feed Plants

    8 May – 20 Oct
    every 2 weeks

    From 8th 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. Harvest Leaves

    4 Jun – 20 Oct

    Start cutting from 4th June when plants are well rooted and the shoots are leafy. Pick little and often through to 20th October, 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.
