We have a small section of alders on our land (SW Ireland), many of which are looking pretty crook. Very thin crowns on many of them and lots of leaf growth coming straight from the stems. Anyone have any ideas?

I would start with Alder leaf beatle, which you won't be able to do anything about .

Phytophthora is possible,  but you won't be able to do anything about.

Wait and see what happens next year.

Thanks SmG. Alder leaf beetle isn’t supposed to have got to Ireland (yet) whereas there’s a bit of a larch plantation just a hundred metres away with some poorly trees in it. Does Phytophthora tend to kill a whole plantation or just some trees in it?
