03 May 22, kathy (USA - Zone 9a climate): 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?

26 Apr 23, Lynda (USA - Zone 8b climate): 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?

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?
