Ash before oak – we are in for a soak
Oak before ash we are in for a splash
In reality oak pretty much always comes into leaf before ash. In the last fifty years oak has always leafed before ash. It has not always been this way – in the 18th century when it was less mild ash did often flower before oak – thus the quote.
Climate change has changed all of this – usually oak leafs in late March-May which is about two weeks earlier than 30 years ago. Ash usually leafs during April and May, about 7-10 days earlier than 30 years ago.
Not this year though.
I have 5 oak trees and a number of ashes.
Four of the five oaks are just coming into leaf but so are all the ashes – it is a dead heat.
I can’t really explain this as it has been a mild winter in a warming world so oak should have beaten the ash by quite a distance – any ideas?
