Die back in robinias

[Jon Lad]

I have noticed a significant amount of die back in the crowns of a number of Robinia pseudoacacia Frisia lately. I was wondering if it was localized to this area or if anyone else has noticed this. A consequence of the winter we had maybe?

I noticed this last year actually, almost always in the Frisia's. I've hardly noticed it in the green-leaved original type, they seem to be doing fine.

 

I would say it was to do with the stresses of reduced chlorophyll, a cold winter and a dry spring this year but like I said I've been noticing the decline since last summer!

There is a thread on here regarding the frisia die back,but may not be relevent to pseudoacacia.

Sad I know but it was on gardeners question time a while back. It's a phytophthora.

I doubt it. The AAIS issued a tree damage note a couple of years ago regarding Frisia dieback - the direction that the RHS and other bodies were looking into was a vascular wilt disease.

The incidence seems to increase after drought conditions - hardly ideal conditions for Phytopthera...

A timely thread,

 

Just happened to notice a dead Robinia in my aunts neighbours garden this weekend in Sale, Cheshire. Apperently this and three others in the street all started to die back from spring time 2009.

 

Now all very dead! And now I know why. Cheers for the post.
