Leaf curl and discolouration on Italian alder

[Baxter]

Hi all

 

I planted a group of Italian alder earlier this year. The buds recently burst and were apparently looking green and in full health until very recently.

 

The leaves are beginning to curl and darken in colour as illustrated in the pictures below.

 

I have checked 'Strouts and Winter' but not convinced by anything I've found related to Alnus.

 

I'd appreciate it if any one has seen this before or could shed any light on the issue.

 

Many thanks

Nick

It could be a case of Phytopthora alni, but I haven't confirmed any cases myself so I am just going on what I know of it from various sources. Try the Forestry Commission info. Maybe share your findings with us here if you follow it up?

Most likely Phyophora I beileve as daltontrees said

Thanks for your replies.

I did look at the FC phytophthora alni fact sheet before posing this and the leaf symptoms seem to be yellowing of leaves and not until late summer. I'm not ruling it out though! I'm also suspecting frost damage?

Possibly frost damage?
