Growing guide

Step-by-step instructions for growing Spinach

  1. 01

    Sow Small Batches

    8 Feb to 24 Apr every 3 weeks

    Sow a short row or patch around 8th February - 24th April, 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

    31 Mar to 14 Apr

    When seedlings are large enough to handle, from 31st March, 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

    24 Mar to 21 Apr

    From 24th March, 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 24th March - 21st April regularly.

  4. 04

    Keep Well Watered

    31 Mar to 16 May

    From 31st March through 16th May, 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

    21 Apr to 5 Jun

    Start picking from 21st April and keep going until 5th June. 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.
