I'm in exactly the same boat except mine are half your size. mine are doing the same thing. I gently peeled it back and saw another yellow leaf forming. I'm pretty sure it's the start of a sprout. As this is my 1st attempt as well.....my theory is let it grow and see what happens (I'll still "stake" it for support) Then have a better understanding with my next batch

apparently ive heard if you cut the top of the plant dies unsure just let them grow naturally

My Brussel sprouts are growing well about 80cm tall but the sprouts are still only pea size. They were planted end of June. Will the sprouts develop from here or is it now too late for them? Also have celery growing well but all pencil thick, planted at the same time - will the stems thicken now? Many thanks for your help Susan

I am in country SA and have the same problem, mine are nearly a metre tall and no sign of sprouts! I am about to pull them out and try again next year. I was told that they should be sown in Jan/Feb so that they are mature by the cold of Winter. They need good frosts to fruit, so I guess that we missed it for this year. I have also had broccoli but they didn't get a good large head on them. We ate the "broccolini" though as they were delicious. Any clues to good broccoli next year?

Brussel Sprouts are in the same family as Broccolli.Cauliflower and Cabbage so grow BS the same way you would these vegetables and yes Jan-Feb is the correct sowing time for these types of vegetables they are a winter autumn grower.

Hiya Chad, Have the same problem but have noticed the tiniest of buds in the crook of the leaves (closest to the stem) ..... fingers crossed these are baby sprouts .... will just have to wait and see. Cheers Michele

Hi Chad, You need to be sowing your seeds as early as December (Some varieties, November) and setting the seedlings out in mid January you if you are anywhere close the Sydney climate (I am in the lower Blue Mountains). The information on gardenate is sometimes too general. Also the harvest time is 20-28 weeks not the 12-13 stated here. I had the same problem as you
