Cauliflower Conundrum

I have heard cauliflowers grow quite large. I have never grown them before and have just planted out the first few little ones ( at the moment!) When they get bigger is it ok to cut some of the large outer leaves, or can i snap the leaves over the white head?

thanks

 

You`ve planted them out a bit early G G. However, what variety are you using?

 

The packets in the greenhouse!!

it said to sow them in march. I have got cloches on them so they should be ok... will they??

i used plastic, clear orange cartons with a lid on with air holes.

if i have dont them a bit early i do have a back up '2nd' crop. I was actually going to have them so i could have a continual(-ish) crop. but they may save the day!!

thanks

p.s. do you know the answer to the original question?
