I've heard somewhere that 'having green fingers' (in the States it's
'having a green thumb' and in France it's 'having a green hand') that
it's not only because one is good at gardening but because of some
chemical reaction from one's hand onto the plants (and vise versa). Now
is this true?


And does this account for the incredible hulk?

Perhaps the Jolly Green Giant?

I've not heard of this, anyone know of some proper science on the subject?
I always thought it just that some people take the trouble to understand
their plants requirements and after a while it come naturally.
