S = Plant undercover in seed trays P = Sow seed

  • 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 45°F and 86°F. (Show °C/cm)
  • Space plants: 18 - 24 inches 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
  • Mature brussels sprouts

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.

Never grown Brussel sprouts before. They have grown high, but also have yellow flowers, no sprouts as yet. Will they grow now, or remove the plants?

Maybe let grow for another month and sees what happens. Possibly you should have planted quite a bit earlier. I have the same problem with savoy cabbage the last 2 yrs. Producing lots of leaves and no heart. Temps are now high teens at night and around 30 in the day - probably too hot for cabbage broccoli here.

Depending if you live in a cool or warm temperate climate, and what month you planted them in. It could be too late if it is to warm where you live, otherwise give it a bit longer to see if they produce.

Trying to understand when to plant my brussels sprout seeds in Zona 10a. It says about P = sow seeds in Oct. Is that meaning to sow seeds directly in my garden? Because after that is says to start seeds in trays and plant out 4 - 6 weeks. Should I start them in seed trays and if so do I plant now so they can be transplanted in my garden in Oct or do I wait until Oct and just plant the seeds directly in my garden? Sorry the info is confusing.

Use seed trays to start your brussels sprouts, plant out as it suggests on the web page. Brussels Sprouts prefer cold/cool climate, so you need to grow them in your cooler months. October is a suggestion, November might work better if your weather is still warm in October.

Hi what is the best fertiliser for my brussel sprouts in pots some say Tui Vegetable food but I am reading to avoid too much nitrogen as they are 30cm tall now. some say Tui Novatec premimum or blood and bone???? so confusing thanks very much kind regards Sarah

The only way to grow Brussels Sprouts is under fine mesh netting. This keeps off all the bugs and is true for all brassicas. Just drape the mesh over the crops and anchor the sides with stones or pegs. You will be amazed at how good your crops are. Mulch heavily so you don't need to remove the mesh to weed. You can buy this mesh at Mitre 10, it's called "quarantine mesh"

Hi fellow gardeners. I'm not having much luck with any normal seeds. I think I am going to source Heritage seeds. Perhaps I'll have better luck. Happy New Year & Happy Gardening. Tina

I'm in northern Tasmania and planted my Brussel sprouts in May as well. The whole lot went to seed after producing a few very loose sprouts. I though a pout using the leaves in soups etc as I hate waste, but I read that they are quite bitter so I guess the lot go into compost. Any comments welcome

I had the same experience, Kay, but I did harvest the plant on the weekend and made a delicious soup with the leaves. I put the hard stems in the compost. The base stock for the recipe was one diced onion and six cloves of garlic chopped and softened in olive oil, 2 litres of chicken stock, 1 cup of white wine, 1 cup of water, salt and white pepper. Add the leaves and 250g of mushrooms and simmer away for an hour or so then blitz with a hand blender. I also added half a cup of cream at the end. It was really delicious and the left overs went into the freezer!
