I planted my brussels sprout seeds in October of 2013. Here it is May 2014 and they are still as small as pencil erasers! Will they ever grow here?

did they mature? enough fertilizer and water? no Asian worms depleting the soil?

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?
