Saw it last night, I thought it was a bit 'bitty', the presenters are judging the allotments to find the 'best three' out of nine I think, but do not reveal their scores.
You get to see the odd allotmenteer, but not the whole of their plot, and they appear to be judging it all in February for some reason, surely not the best time to look at them?! Jury's out I'm afraid..... :-\
