Pruning elms

[Mesterh]

Is there any info if pruning an elm may help with infection of DED?

 

I know that sounds like I'm trying to infect an elm but I'm not.

 

Got a decent ish sized one(the only ones I see are shrub/hedge size usually) that may need pruning (phone lines etc) but was thinking if it may create a path for infection I might try and persuade them not to prune it.

 

Any info mucho appreciated.

 

Oh it looks very healthy with no signs of leaf discolouration die back etc.

The cambian layer needs to be a certain thickness to allow the beatle to bore into. This is normally around 25 years that the cambian layer to become thick enough.

Elm also ripps very easily, even when it is under cut, be carefull

My co pruned the majority of the mature Elms that make up the street trees in Brighton and Hove, pretty much the last large scale stronghold in the SE and awesome to see. They do tear really badly! like nothing else I've ever cut!

 

Basically told by the LA to avoid pruning/creating a fresh pruning wound too far into the growing season eg. after approx end of May.

Yeah you aint wrong about the tearing. There is nothing worse I think.

 

Thinking back I have prob pruned more than I think I have but that was slash and hack on line clearance so caring about trees didnt matter much back then, ish.

 

Thanks for the info.

 

I shoulda took more notice but iirc the tree must be a 45 footer with dbh of maybe 24"
