Brussels Sprouts in Barnes

Brassica oleracea (Gemmifera Group)

Brussels sprouts are a hardy winter brassica (cabbage family) that form sturdy, leafy stems often around 60–90cm tall. They produce edible mini-cabbage buds along the stem from autumn through winter. Thanks to their cold tolerance, sprouts remain productive into late winter, and frost actually improves their sweetness.

Grow Brussels sprouts for a harvest from autumn through winter, with sprouts maturing from the bottom of the stalk upwards.

  1. Sow Seeds Indoors

    15 Feb – 2 Mar

    Sow seeds indoors in modules or pots around 15th February - 2nd March. Use a good seed compost and cover with of soil. Keep at for germination, which takes 7-14 days.

  2. Prick Out Seedlings

    8 Mar – 15 Mar

    Once seedlings have their first true leaves, prick them out into individual pots around 8th March - 15th March. Handle by the leaves to avoid stem damage and plant at the same depth as before.

  3. Harden Off Plants

    29 Mar – 5 Apr

    Gradually acclimatise plants to outdoor conditions over 7-10 days around 29th March - 5th April. Start with a few hours in a sheltered spot and increase exposure each day.

  4. Transplant Outdoors

    15 Apr – 29 Apr

    Plant seedlings into their final position around 15th April - 29th April. Space them apart in firm, fertile soil. Firm the soil well around each plant to prevent wind-rock.

  5. Install Pest Protection

    22 Apr – 29 Apr

    Immediately after transplanting, cover plants with fine mesh netting to protect against cabbage white butterflies and pigeons. Fit brassica collars around the base of each stem to deter cabbage root fly.

  6. Feed Plants

    6 May – 5 Dec
    every 4 weeks

    Apply a nitrogen-rich fertiliser every 28 days from 6th May until 5th December. Water it in well to support the heavy leafy growth needed for good sprout formation.

  7. Harvest Sprouts

    10 Aug – 5 Dec

    Start harvesting from the bottom of the stalk upwards around 10th August - 5th December. Pick sprouts when they are firm and about the size of a walnut. Frost improves their flavour, so continue harvesting through winter.

Plants to avoid

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.
