Gathering nuts in February

Whilst contemplating cutting the grass in the garden I came across a few of last year's hazel nuts. For some reason the old nursery rhyme Here we go gathering nuts in May entered my mind. There are of course no nuts to be gathered in May, the time for that is the Autumn. So, what does it mean? Over to you Prof. Google:-

It seems that it is a corruption of “Here we go gathering knots of may”, referring to the old custom of gathering knots (bunches) of hawthorn  blossom (a.k.a. may) on May Day. 

You live and learn!
