I don't firm my soil around my Brassica anymore and i always get 2-3 lbs heads on my broccoli and cauliflowers.
3 or more months of side shoots from broccoli .
Also deeply loosen the soil before planting them since started doing that the heads have been larger and firmer.
as said it is myth. Since you should be using cloth over your  Brassica to keep the cabbage white at bay the wind issue is also myth. you guys need to move into 21 century   with you garden techniques instead still using those from the old world war 2 garden manuals.

You do make me laugh GG,  :D  I see your copying TG's idea of not firming the ground.     ;D ;D ;D

john Jeavon taught me the method of not firming the ground for planting my Brassica plants.
