Ash - early leaf drop

[Fungus]

I'll look a little closer for pests / diseases / other symptoms - I've only noticed them when driving about and assummed it was a general weather thing.

 

Giles,

Chalara fraxinea has killed ten thousands of ashes in less then 10 years in Scandinavia, Poland, Germany (Rügen) and recently in The Netherlands, where it only is present since 2009 and has spread all over the country in 2 years time, so if the pathogen has now reached the U.K. too, it should be identified, documented and reported to the concerning phytopathological experts and authorities.

Thanks Fungus, I'll check it out.

I'll check it out.

 

Giels,

In case you need support in assessing, identifying and documenting the pathogen, you can contact the Forestry commission.

doh. yeah its the other way around. Ash before oak get a soak, oak before ash get a splash. etc

 

With respect to this "gem" of wisdom...it refers to the leaf break afaik.....?

Might be you have a different genotype of Fraxinus excelsior in te U.K., as on the continent ash is (one of) the last one(s) to develop its foliage after it has blossomed and is (one of) the last tree(s) to shed it's leaves.

i agree:001_smile: it is.

 

long time no see giles, hows tricks?

 

lot of ash round here thinned out due to drought early on

really?imo Ash usually one of first to drop.

 

See i'm all confused now. In our garden we have an ash. it always comes into leaf after every other tree in the neighbourhood and always drops its leaves last.

 

 

Maybe this tree is special!!

Well, I finally got around looking closer a couple of weeks back and think you've hit the nail on the head.

 

No evidence of fungi or disease, but what was noticeable was the age class. The majority of the trees affected are youngish - around 30cm dbh and they're mostly hedgerow trees. It looks like the surrounding hedge plants such as hawthorn have been more successful at drawing water from the soil and have either out competed them for the available moisture, or just survived better.

 

The older bigger ash seem to be fine, I think it's just the younger ones. I guess there might be a long term effect where an age class is missing.
