Default Autumn leaves

Despite the fall in temperature and the pretty severe gales we've had, oak
and beech trees around here still have many leaves on and plenty of them are
still fairly green. What about other parts of the country?
We still haven't had a frost here and today has got warmer but yes, it's
lashing with rain again!

We've had only one morning when the windscreen of my car was frosted - and
then it was fairly half hearted.

At Norwich, it is a very mild day, windy and wet. Last night was
dreadful, the roof creaked all night; I suppose it could be the vermin
but after a glass of wine, I can't tell the difference. The trees have
an enormous amount of greenery on them. However, I don't think it is
anything to do with weather - correct me if I am being ignorant but
don't trees drop their leaves when their produce abscic acid? I am not
sure whether it is really known whether this is related to the spectrum
of daylight or what - I expect Nick McLaren will know & I look forward
to the reply.

I'm sure Nick or David will be along to tell us - the autumn colour is
something to do with sugars, IIRC but I find it interesting that the ash
trees have lost their leaves, for example and the oaks and beeches are
holding on to them.


there's a big difference in the times when trees shed their leaves -
whitebeam shed a long time ago, mulberry (which is always very late to
come into leaf) is still in full leaf - though yellow up here. The
sycamores opposite hold on to their leaves much longer than the horse
chestnuts.
