Growing guide

Step-by-step instructions for growing Spinach

  1. 01

    Sow Small Batches

    24 Mar to 7 Jun every 3 weeks

    Sow a short row or patch around 24th March - 7th June, using fresh seed every 21 days for a steady supply. Sow thinly in shallow drills about deep and keep the soil lightly moist until germination.

  2. 02

    Thin Seedlings

    14 May to 28 May

    When seedlings are large enough to handle, from 14th May, thin them to the final spacing so each plant has room to make broad leaves. Use scissors rather than pulling if the roots are tangled, and water the row after thinning.

  3. 03

    Check for Slugs

    7 May to 4 Jun

    From 7th May, watch young plants closely and clear slugs and snails by hand, traps, or a simple barrier. They can strip a row in one night, especially in damp weather, so check at 7th May - 4th June regularly.

  4. 04

    Keep Well Watered

    14 May to 29 Jun

    From 14th May through 29th June, keep the soil evenly moist so the plants stay tender and do not bolt early. Water at the base in dry spells, and give container-grown plants extra attention because they dry out fast.

  5. 05

    Harvest Leaves

    4 Jun to 19 Jul

    Start picking from 4th June and keep going until 19th July. Take outer leaves for cut-and-come-again harvesting, or cut the whole plant just above the crown if you want a single larger crop.

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.
