I have just lifted my crop of shallots and onions. While the shallots have
done better than they have ever done - huge bulbs - the onions have done
worse, some hardly growing at all from the sets that I planted. Both were
planted in the same bed.

Does anyone have any idea why this should be?

None what so ever, our shallots (both French type) have done well and our
onions are enormous, bigger than they have been for many years, strong too.
What variety did you grow, different from normal?
