planting time for Brussels sprouts depends on the variety and can be as early as Oct-Nov and as late as Feb. Good seed providers should state what month they should be planted. Look up an old book - Vegetable gardening in Australia by Norman de vaus. He has good advice and a good understanding of how to grow brussels sprouts. Finally some of the seed you are buying may not be well selected and may never give good spouts no matter what you do. Hybrid seed is one option if you are sick of failing at Brussels sprouts.

Our Brussel sprouts don't seem to be growing. We have healthy looking plants (leafy cabbage like with a centre the size of a tennis ball) We have taken away 5 layers of leaves from underneath, but still nothing. They have been growing approx 4 months from seedling. Hope you can give us a tip to get the sprouts started... With thanks.....

I tried to grow Brussel Sprouts but the little sprouts are tiny and then they open on the stem. I didnt get a harvest out of them. How do I get those big sprouts on the vine
