I’ve found exactly the opposite Al!

 

Big trees that have been tonked the regen has flushed then died off completely within a couple of years.

That's interesting and curious Mark because I'm geographically and climatically not too far away from you.

So I have taken care during these years to annually observe dozens of the Ash that i've worked on (circa 40% crown size reductions) and the only ones that failed to survive were the ones that exhibited slightly advanced Chalara infection.

This shows me that early (always) and medium (usually) stage infection reacted well enough to endure.

 

Of course they may all die tomorrow but so far so good.

Larger trees are seeming to retain better vigour and react positively to pruning, but  only in the early stages. 
at best I am buying a relatively short reprieve for any ash I am working on and am very wary of customers feeling like they have wasted money retaining them for only a couple or so years

Same things here for me Pete. The older trees appear to deal with all a bit better.

 

I am always very clear to the clients about the 'guarantee' that the tree may/may not survive.

In most cases though, my clients have enough disposable income to 'have a go' but the results have actually nearly always been positive for the tree.

(So far).
