Elm tree reduction ?

[defenderjack]

Brighton is a different case, it is protected by The Downs.

Plus there is some very clever use of dead trunks to attract the beetle then removal to burn once eggs have been laid. (or something)

Hence the signs saying something like "you are entering a DED protection area or sommat on roads leading in.

yeh the problem with leaving "trap trees" is that they have to remember to leave enough budget to clear them at the end of the summer otherwise all youve done is create the perfect habitat ! im not sure im convinced myself , i cant see why a beetle would prefer a dead trunk to a fresh leaf

They lay eggs under the dead bark where the larvae feed and mature then the beetle feeds on the fresh growth spreading the fungus picked up at larval stage

think a few need to read up on DED

Well however they do it, it works! 'cos they are the only mature elms I've ever seen.

(Hats off to the suits involved btw)

and the tree in an attempt to hnder the fungus spreading shuts of its zylem an effectively commits suicide

clever tree...just biding its time?

if its root system survives,itll sucker...if those suckers flourish whose to say they wont mature?surely a possibility?

[T14EES T14UNK]

Ditto

As far as I was told, about twenty yrs ago, once the tree is infected it chucks out phenols which is an attempt to block off any infection. In effect it chokes itself. I seem to recall being told that due to the speed of the phloem, any infection takes about 8 minutes to get to the top!!

 

I wouldn't worry about timing to be honest. An elm is gonna throw out shoots at every pruning cut. Just keep it as minimal as possible but enough for it to be worth doing.
