Growing Broccoli

I planted my broccoli at the beginning of June and they have grown very well but so far They haven't developed a head. I fertilised them every two weeks since planting them until a couple of weeks ago when I was told that I had overfertilised them. Is this why no heads have grown?

They won't head up until probably 10-12 weeks old. If you used a high % N fertiliser (12-15% N ) then you have over fertilised them (also depends how much you put on). If the plants are very big too much N. Stop fertilizing them and maybe cut the watering back a bit Trial and error. I have planted seeds this year and have had poor results -back to seedlings for me with broccoli and cabbage..
