Q.Growing broccoli
Why does m y broccoli always grow enormous stalks and leaves and have hardly any florets. should I look for a particular variety? I have a clay soil which I have been improving every year. Other brassicas do quite well though they also tend to grwo tall. e.g. caulis and brussels sprouts. Cabbages are looking quite good.
