In the autumn I planted various brassicas. The cabbages grew and made large
cabbages, the cauliflowers grew and made good heads etc. However the
brussels sprouts grew stems with leaves and little tiny sprouts about the
size of a pea. They are all in the same plot and treated the same way. Now
it's spring and I am about to pull out the brussels sproutless. Can anybody
tell me why the sprouts never grew any sprouts?
