Growing guide

Step-by-step instructions for growing Sprouting Broccoli

  1. 01

    Sow Seeds Indoors

    4 Apr to 19 Apr

    Sow seeds in modules around 4th April - 19th April, about deep. Keep them in bright, cool conditions and prick out the seedlings once they have a couple of true leaves.

  2. 02

    Grow On Seedlings

    25 Apr to 9 May

    From 25th April, keep the young plants moving steadily in good light and water them lightly but regularly. Avoid letting them become pot-bound, as checked growth can lead to weaker plants later.

  3. 03

    Harden Off Plants

    9 May to 23 May

    Harden off seedlings over 15 days from 9th May to 23rd May. Give them a few days outside in shelter, then leave them out for longer each day before planting.

  4. 04

    Transplant and Firm In

    2 Jun to 16 Jun

    Plant out from 2nd June, setting each plant apart in rows spaced wider than that. Water in thoroughly straight after planting, then firm the soil hard around the stems so the roots do not rock in the wind.

  5. 05

    Protect from Pests

    9 Jun to 2 Nov

    From 9th June, cover the crop with fine mesh to keep out cabbage white butterflies and pigeons. Fit brassica collars round the stems at planting time or soon after to reduce cabbage root fly damage.

  6. 06

    Feed Plants

    30 Jun to 19 Sept every 4 weeks

    Start feeding from 30th June and repeat every 28 days until 19th September. Use a high-nitrogen feed while the plants are making leaves, then stop before the coldest weather so the growth stays firm rather than soft.

  7. 07

    Harvest Sprays

    17 Nov to 25 Feb

    Cut the first side shoots from 17th November and keep picking until 25th February. Harvest the shoots while they are tight and tender, cutting just above a leaf joint so more side shoots can follow.

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.
