When water freezes, it gives off heat which is often enough to avoid cell damage in the plant foliage. And once the ice has formed, it acts as insulation so even if the ambient temperature continues to plummet, the foliage temperatures remains near the freezing point.
Now there's something I've learnt today, I'd have thought it would have worked almost the other way round by keeping the foliage colder longer.
Thanks for the heads up on that.
They say you learn something new each day, well I hope nothing else comes along, because I've already had my one for today now.
