I may be interpreting the info from this site incorrectly, most of the comments reinforce what i thought, that cauliflower is grown in cooler months and yet this site shows planting times of mid summer with harvest at the end of summer. Can some one please explain thanks

Hi, I have had a similar effect happen to my cauliflower as question #15 as mine were also growing very well and had small curds that separated into lots of stems when they grew a bit larger.Can you tell me what has caused this to happen?

I didn't pick my cauliflower soon enough and the head has a pinky/purple colour on it. Is this discolouration or could it be a fungus? Not sure if I can eat them. Thanks

My last batch of cauliflowers have produced amazing foliage but no curds. We normally get great curds. What has gone wrong this time?

Hi Ros, I had the same issue with my cauli, they told me that it was a different type of cauliflower, it almost looks like a broccoli? I prefer this type actually, easier to cut when you need it.

I had 8 cauliflowers growing beautifully, each had a small curd; but as the curds started to grow a bit bigger, they separated into lots of stems. Why did this happen, please?

Hi again Liz I live in Perth (WA) and we are at our coldest and possibly wettest time now!! I have about 15 plants and want to reduce it to however will grow in the tubs I described. Do you think 6 would still be overcrowded?

I am trying to grow cauliflowers successfully. The outer leaves which are long are going quite curly and look as if something is wrong. The head of the cauliflower is still very small and they have been in the ground for at least two months. Any ideas?
