How to kill off an ash tree ?
 

This is the problem.
An ash tree growing tight alongside the buttress of an old building.
The trunk is about 10" dia.
We have cut the tree down, and limbs off, as far as possible in the hope
that it would gracefully die.
It still makes very robust shoots and this is the 6th season of our trying
to be rid of it.
The current plot is to drill holes in the trunk and insert poison of some
kind.
I am normally against anything of this kind but the tree has to go.
Any suggestions please on what poison might be effective?

Thanks,
Nicholas.

I have killed them with "Root out" weedkiller, but was told later the bleach
poured into drilled holes works as well.

Ash trees are a complete b*gger. I have a 2" 'trunk' by my fence that is
still shooting after 10 years of weekly abuse with shears.

I suspect that drilling holes down into the trunk and filling with creosote
might work. Not tried it yet, but ten years of this miserable runt
sprouting along my fence is enough to tempt me ...

Neat Roundup or similar, don't dilute it, just drill some holes and fill
them with Roundup.

The problem will be growth from dormant buds in the cambium layer,
between the bark and the heartwood. The heartwood is already
dead. Putting brushwood-killer into the deep holes round the edge
of the heartwood might work, but only as it leaches into the cambium
layer. You have a live tree with lots of roots and trunk - albeit not a
tall one.

I suggest that you debark as much of the remaining trunk as possible,
this removes the dormant bugs. It also gives the fungi lots of ways
in.

There is a story that says that copper nails will kill a tree, but I've
no idea how long, or how many, it takes.

I have an 2 foot ash stump on my boundary that was alive and spouting
when we moved here four years ago, I used the 'strip bark' method on
it's own and it is now dead. I believe it was felled about three years
before we arrived (the full live tree is still on Google Earth!). So
it's about the same age as yours.

Ammonium sulphamate
IIRC the active ingredient of RootOut. I have heard that, excellent
though it may be - and in my experience very good against Ivy, it is no
longer available as a weedkiller but is available as a compost
accelerator (the EEC has a lot to answer for)

There is an ebay seller who sells this as an accelerator complete with
out of date weedkilling instructions.
