Brussels Sprouts

Brussels Sprouts in Young's End

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

2 Mar - 17 Mar

Sow seeds indoors in modules or pots around 2nd March - 17th March. Use a good seed compost and cover with of soil. Keep at for germination, which takes 7-14 days.

2
Prick Out Seedlings

23 Mar - 30 Mar

Once seedlings have their first true leaves, prick them out into individual pots around 23rd March - 30th March. Handle by the leaves to avoid stem damage and plant at the same depth as before.

3
Harden Off Plants

13 Apr - 20 Apr

Gradually acclimatise plants to outdoor conditions over 7-10 days around 13th April - 20th April. Start with a few hours in a sheltered spot and increase exposure each day.

4
Transplant Outdoors

30 Apr - 14 May

Plant seedlings into their final position around 30th April - 14th May. Space them apart in firm, fertile soil. Firm the soil well around each plant to prevent wind-rock.

5
Install Pest Protection

7 May - 14 May

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

21 Nov - 21 May
every 4 weeks

Apply a nitrogen-rich fertiliser every 28 days from 21st November until 21st May. Water it in well to support the heavy leafy growth needed for good sprout formation.

7
Harvest Sprouts

21 Nov - 25 Aug

Start harvesting from the bottom of the stalk upwards around 21st November - 25th August. Pick sprouts when they are firm and about the size of a walnut. Frost improves their flavour, so continue harvesting through winter.
