Growing guide

Step-by-step instructions for growing Sprouting Broccoli

  1. 01

    Sow Seeds Indoors

    13 Apr to 28 Apr

    Sow seeds in modules around 13th April - 28th 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

    4 May to 18 May

    From 4th May, 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

    18 May to 1 Jun

    Harden off seedlings over 15 days from 18th May to 1st June. Give them a few days outside in shelter, then leave them out for longer each day before planting.

  4. 04

    Transplant and Firm In

    11 Jun to 25 Jun

    Plant out from 11th 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

    18 Jun to 3 Nov

    From 18th 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

    9 Jul to 20 Sept every 4 weeks

    Start feeding from 9th July and repeat every 28 days until 20th 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

    18 Nov to 26 Feb

    Cut the first side shoots from 18th November and keep picking until 26th 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.
