ok - many thanks to you and Sacha for the overview.
I'll keep a lookout for the leaf-spot.
What is the normal life-cycle of the leaf from now on - what should
expect? Do the green leaves, if healthy, remain from now until next
spring.

They die back quite a bit in winter and then there's a big burst of
growth in spring.

They also often die back in the summer if they dry out.
