I am sorry if I am on the wrong site, but I have searched the internet without success for an answer.

My question is, that I have lived here for 25 one of the previous owners with my neighbour used some bird poo with a berry into my apple tree. So the mistletoe could well be over 40 odd years old. I always tell people that comment on it that it is male and never has berries.

UNTIL……..I noticed some last week. 
I suspect this is unusual and more to the point how could it have happened. ?

I have a couple of bird houses in the tree and lots of tiny birds frequent it. ( In the past they were blue tits, but I think it is a different species at the moment )
