  • Young plant (CC BY-SA 3.0 WikiMedia)

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

Suited to growing in cooler climates.

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

In warm areas they are likely to become 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. (Planning an Idaho Vegetable Garden: Educational Communication online Publishing Catalog Gardening www. edComm/catalog.asp.)

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.

Seed was planted in June. When should Brussels sprouts be harvested in zone 7?

I am in Zone 8b and planted nursery plants in February but they have not produced sprouts and it is probably too hot for them to now.

I am a first time gardener with brussels sprouts. I live in zone 8B in Texas. We are at the end of April and the Google play said I can still direct sow the seeds and get a crop. Is this true?

Plant now. It's worth a try.

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?
