Thank you folks for your messages and help.
Yes, they are expensive to buy but i do like a cauli now and again. So think about Boron and also a sunscreen for them. They go pale pink when almost newly grown so i shall have to grab them more quickly rather than hope they will grow bigger.
As well as putting my query on line i also sent Marshalls a couple of photos of the appearance of the top and underside of the caulis. They came back today saying that they have "gone over" and that i should have harvested them sooner.
The good news from the Brassica cage is that the Brussels are doing ok as pea sized buds - but they are coming! Hurray!
Thanks again - great result on my query. Val
