Question
QUESTION: Why has my latest crop of cauliflowers produced fantastic foliage but no heads?

ANSWER: Coral:

My first thought was cross pollination but then I think that the reason could be defficiency in the plant food that you are using. I would reduce the amount of nitrogen that you are using in your plant food. Give them a little more time to mature.

Best wishes.

QUESTION: I disagree with your answer since a crop adjacent to these - same bed - just 8 different plants all produced fantastic curds.All plants were treated in exactly the same way. They are all in the same ground and all received the same amount of sunlight and plant food. This has never happened to me before and I am a very keen vegetable grower.
Thanks Coral

Answer
Coral:

I am sorry that I could not be of better service. However, I appreciate your disagreeing with me. As you know it is difficult to analyze these problems on the computer.

I am at a loss to recommend to you. Do you have any idea what the problem might be?

Best wishes.
