Why do caulitflower heads turn from white to pink
by Linda James
I have a large allotment in York, England, and for the past two years I've grown cauliflowers and each time as the heads start to grow the florets have turn a pink colour (which disappears when I cook them). I wondered if it was a deficiency in the soil, or the fact I'm using water from the allotment standpipe?
We've had a really hot, humid summer this year and the cauliflowers 'pinked up' as soon as the heads formed. Would appreciate advice from anyone who has experienced the same problem.
Before closing I just want to say that your no-dig ideas are in operation all over the allotment site - fully embedded, if you'll pardon the pun!
