Growing Brussel Sprouts in Tasmania

Introducing Brussel Sprouts

Brussels sprouts love the cool, wet weather in Tasmania and produce an abundance of miniature cabbages on long stalks. Mulch and feed them well, and they will eventually reward you with a delicious harvest.

Classic Mistakes

Be sure to keep the soil rich and well compacted. These top-heavy plants can topple over if they aren’t anchored firmly in the soil.


Grow in: Full Sun

In warmer climates, brussels sprouts like some shade, but in the cool, Tasmanian climate they do better in full-sun.

Soil Preparation

Brussels sprouts are heavy feeders, so dig in some well-rotted manure and compost, as well as some lime if necessary.

Sowing Seed

Sow seed: November-February
Sowing depth: Twice the height of the seed

Sow seeds every 4 weeks during the planting season to prolong the harvest

Seeds are best started in trays and transplanted into the garden once they’re established. Keep the soil damp while they germinate. They need plenty of light once they’re up to stop them from getting too leggy.


Plant seedlings: November-February

Plant every 4 weeks during the planting season to prolong the harvest

Plant in heavy clay soils where possible. These plants are big and top-heavy. A nice, firm soil helps to keep them from toppling over in strong winds.


About 60 to 80 days before harvest, pick the leaves of the lower part of the plant, to encourage better sprout growth. Be sure to leave enough leaves for the plant to keep growing and putting energy into lovely big sprouts.


Brussel sprouts like cool, moist roots. Be sure to keep their soil damp.


Brussels sprouts needs lots of nitrogen for their early growth. Add well-rotted manure or fish emulsion through the early part of the season. Do not to overfeed with nitrogen towards the end of their growth, as this can cause the sprouts to turn brown. Once the sprouts start to form, give them a balanced feed every four weeks.


Mulching brussels sprouts helps to keep the soil moist and cool. Apply a generous layer of organic mulch like lucerne, sugarcane or pea straw.


Harvest: 4 to 5 Weeks After Planting

Pick sprouts when they are walnut sized and still firm. Harvest from the bottom of the plant up.
