Brussels Sprouts

Brussels Sprouts

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.

1
Sow seeds indoors

30 Jan - 13 Feb

In late winter, sow 2 seeds per module or small pot of peat-free seed compost, about deep. Water them in and keep the tray in a warm spot (e.g. a heated propagator or sunny windowsill at ~) to germinate in 1-2 weeks.

2
Pot on seedlings

6 Mar - 20 Mar

Once seedlings have 2-3 true leaves, pot each into its own pot of compost, burying them up to the lowest leaves to encourage strong roots. Keep them in bright light and water regularly as they continue to grow.

3
Harden off seedlings

3 Apr - 10 Apr

After the risk of frost has passed around April in Winding Wood, begin hardening off by placing the young plants outside for a few hours each day, increasing exposure gradually over a week.

4
Transplant outdoors

20 Apr - 1 May

Plant the hardened seedlings into prepared ground in a sunny, sheltered spot. Space them about apart and at the same depth they were in their pots. Firm each plant in and water well to settle the soil.

5
Fertilise plants

23 May - 6 Jun

When growth begins around May in Winding Wood, feed the sprouts with a general-purpose fertiliser or some well-rotted manure to support their long growing season.

6
Support plants

24 Jul - 23 Aug

As the plants grow tall, mound up soil around the base (hilling up) in late summer to brace the stems, and use stakes or canes if needed to keep them upright.

7
Harvest sprouts

7 Nov - 22 Jan

Starting around November in Winding Wood after first frosts, begin harvesting the firm, tightly closed sprouts from the bottom of the stem. Continue picking through winter, removing any yellowing lower leaves.
