The Tuesday tree: oak before ash
There’s an old bit of country lore that runs something like,
‘Oak before ash, we’re in for a splash; Ash before oak, we’re in for a soak.’
Here’s a typical example of what the oaks are looking like at Castle Beastie at the moment:
All the oaks are puffy with their new rusty green foliage.
And here is a typical little ash tree silhouetted against the bright sky:
Not very pretty at the moment, is it? Those dark clumps are bunches of last autumn’s keys. Compared to the bright green birch trees and even to the firs, this ash looks quite dead.
There are in fact a few hints of green on it, and a neighbouring ash is showing proper signs of new life,
but they are far behind the oaks this year.
Will the trees’ prophecy be borne out? We shall see!
For a more scientific explanation of these variations, I found Gabriel Hemery’s brief article interesting.
