Title: Why do horse chestnut leaves brown and shrivel so early?
Post by: nudephil on 21/10/2020 16:46:50

Listener Sue sent us the following:

I notice year after year that horse chestnut tree leaves brown and shrivel much earlier than other deciduous trees. Why is that?

I am also informed that a moth is getting into deciduous tree leaves to shrivel them - and I also notice that sycamore leaves are blackening locally...

Any answers to her question?

Also, we made this short video that explains what's going on:
