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

Trying to understand when to plant my brussels sprout seeds in Zona 10a. It says about P = sow seeds in Oct. Is that meaning to sow seeds directly in my garden? Because after that is says to start seeds in trays and plant out 4 - 6 weeks. Should I start them in seed trays and if so do I plant now so they can be transplanted in my garden in Oct or do I wait until Oct and just plant the seeds directly in my garden? Sorry the info is confusing.
