March to June planting for zone 6b.

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?

The guide here says plants seeds in March and plant out in May. Most veggies need plenty of sun.

First time growing Brussel Sprouts. Is it o.k. to cut off the larger outer leaves if they are yellowed or otherwise damaged? Will that affect the sprouts in any way?

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?

Gardenate advises plant in SEPT. They need cool or cold weather for best results.
