….i.e. if the tree has no target leave the poor thing alone.

 

The most precious targets move, not there all the time................be very care full.

An infection by Kreutzmaria Deusta usually happens via entry to injuries to stem or large roots. It prefers mechanical injury to bark, ie impact damage or buidling/construction work which damages the roots. It can spread by root cntact from affected tree to healthy tree. Kreutz D. causes a decay in the central part of the roots and low stem, in the early infection stage, for this reason the physiology of the host is not affected, meaning that evidence maynot be apparent in the canopy. Good VTA required. I have 2 big veteran beech trees which are gonna have to come down on the grounds of safety. The tree can be fine one day, puff of wind and the tree will be laying on sits side next day. Seeing a lot of it when we come up against newly constructed estates, where old tree have been left, yet know one adhered to BS5837, and just chopped through roots. I had a builder work on the principle that the tree would just grow more roots. Its as simple as that when your a 200 year old veteran beech.

Arnold, can I ask you if your above post is purely based on your observations or on any particular published material?

 

Not naive enough to doubt it's validity, more a case of trying to understand if Kretz could adapt it's decay stratergy due to it's environment.
