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 the best month to plant young Brussel sprouts plants so they mature in the colder weather?I am in Auckland

We have had Brussels sprouts growing in the community garden, would be better to plant them in cooler months or plant them just before the cooler months so we can harvest them. Brassicaceae same as cabbage and Broccoli, cauliflower to avoid the cabbage moth from eating the leaves? we don't like to use chemical sprays. All natural.

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?
