Oak before Ash we'll have a splash, Ash before Oak in for a soak

The Ash has finally come into leaf a good six weeks later than the oak. You can see it in the left had foreground of the photo.

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

Oak is temperature sensitive so this year's above average spring temperatures caused its leaves to start to grow well ahead of the ash trees. Ash trees are much less responsive to temperature and are believed to respond more to sunshine, although this is yet to be confirmed.
