  • Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 7°C and 30°C. (Show °F/in)
  • Space plants: 45 - 60 cm apart
  • Harvest in 14-28 weeks. Pick sprouts when small. .
  • Compatible with (can grow beside): Dwarf (bush) beans, beets, celery, cucumber, onions, marigold, nasturtium, rhubarb, aromatic herbs (sage, dill, chamomile)
  • Avoid growing close to: Climbing (pole) beans, tomato, peppers (chili, capsicum), eggplant (aubergine), strawberry, mustard

  • Young plant (CC BY-SA 3.0 WikiMedia)

Grown for its small (typically 2.5 cm diameter) leafy green buds, which resemble miniature cabbages.

BETTER IN COOLER AREAS.

Brussel Sprouts will not grow good "sprouts" in warm areas - they open and are floppy.

In warm areas they are likely to be infested with aphids Pick formed sprouts from the bottom of the stems leaving the plant growing. For winter use in very cold areas, dig up plants that have heads developed and set close together in a cold frame or cellar. Pack soil firmly round the roots. Keep cool but not freezing and they will continue to mature.

Culinary hints - cooking and eating Brussels sprouts

Remove any discoloured outer leaves.
Cut in half and steam with other vegetables.
Do not overcook as that produces the distinctive smell that puts people off eating Brussels sprouts!
They go well with a chopped tomato and onion mix.
Traditionally served with roasted chestnuts for Xmas dinner in UK.

We live in Alabama and super new to gardening. Is it too late to start seedlings now?

I live in South Louisiana and a good time to plant seeds in indoor trays is this month; direct sow in ground would be September. Best of luck in your gardening journey.

My Brussel Sprouts cuttings are sprouting now. Where and how best to transfer them to pkant where they best wiuld thrive, in the garden or in separate trays ? I guess with quarantine mesh in both cases?

My Brussels sprouts plants have a purple tinge on the stems. Are they deficient in some trace element? They also seem to be shedding the bottom leaves which have turned yellow .

Sprouts are more a winter thing than Summer I thought. I don't know about cool climate requirements.

I would like to be able to purchase some Brussel tops, as they make a great green to eat with a good roast and the green water makes a fantastic gravy. Do you know anywhere in NSW that I can purchase some? We live in Goulburn NSW

Hi Sally, A friend gave me a great tip this year that has kept my broccoli and cabbage pest free! I got a packet of ping pong balls and drew big eyes on them with permanent marker and stuck them onto skewers and put them in the garden so they were visible and that's worked a treat and I have no even seen any white butterflies in the garden at all. I have no idea how it works and I was sceptical but she swore by it and it has worked for me too, as for snails, I find mulching and some sawdust helps.
