  • 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.

When is a good time to grow brussels sprouts in cool climate from seeds to avoid hot weather?

I planted my brussel sprouts in the fall and they haven't produced any brussel sprouts, only stalk and leaves. They are still in the ground. I used 8-8-8 fertilizer. Do I need to use a different fertilizer?

Gardenate advises plant in SEPT. They need cool or cold weather for best results.

First time growing Brussel Sprouts. Is it o.k. to cut off the larger outer leaves if they are yellowed or otherwise damaged? Will that affect the sprouts in any way?

You could take them off..

My Brussels sprout seeds are 175-200 day to maturity. I have tried to start in doors and plant out in June in a mostly shade area, the last 3 seasons, but have never had sprouts develop. I figured it was because we have been having too warm weather, and maybe not enough sun? This season I started in January indoors, and will put them out in March with some frost protection, with more sun. Thoughts?

Brussel sprouts need full sun 6-8 hours a day. Shade area not ideal

The guide here says plants seeds in March and plant out in May. Most veggies need plenty of sun.

Hi, I actually live in Salalah Oman and temp is always between 25 to 35 degrees celsius. Will it be possible to grow brussel sprouts in this temp?

This crop was named after Brussels, Belgium - where they have grown this crop for centuries. This crop tastes best after a light freeze. I've never tried to grow this crop in your climate.... but my best guess is the plant would not thrive and the brussels sprouts inferior. Research indicates: Sprouts that mature during hot or dry weather will be flimsy and bitter.
