Large entry wounds points.

[AA Teccie (Paul)]

I'm talking about just painting the hardwood and not going to the edges? Isn't hardwood 'dead' so to speak.

 

Flip...'head scratchin time'.

 

Kinda, but it can be utilised for 'storage', i.e. starches, which the tree can call on if needed.

PS Can't you ask summat sensible like H&S Policies n Risk Assessments etc., I can give you loads of useless information then?....forget this biology nonesense stuff which is really important n what it's all about really!

Painting of wounds is useless!

 

This has plenty of scientific research, Shigo etc

 

A large wound creates a large and seprated pocket of dead and walled off wood, that requires huge amounts of input from the tree to compenate for and re adress the axiom.

 

For example when a big limb low on the stem breaks out leaving a long scar and exposed heartwood, the tree forms tension ropes along the edges of the wound. This is called "woundwood/woundwood ribs" but these will also be formed to compensate for the strucural weakness as with the attached image. this reqiures a great amount of resource allocation and can leave the tree in a weakened state (reserves)

 

Whilst this example doesnt quite match the large pruning wound scenario, what i mean to say is that the tree will have to compenaste by laying down a great deal of wood around the area of dysfunctional wood created by the wound and subsequent dissasociation from those tissues.

 

There is no perfect answer to large wounds, except not to make them in the first instance!

 

hope this helps! probably not:001_rolleyes:

"I'm talking about just painting the hardwood and not going to the edges? Isn't hardwood 'dead' so to speak."

 

i see what you mean, but the way i see it (correct me if im wrong) is:

 

A) if the pathogens are sealed in by the paint, this is bad- increased chance of decay etc

 

or,

 

B) if the pathogens aren't sealed in ("allowing the pathogens to move freely"), although this wont increase the chance of decay, it wont decrease it either, as the pathogens can come and go as they please so to speak

 

or,

 

C) i'm out of my depth!

Have you read shigo on this subject?

me? no

Sounds like an experiment for someone to me.

Why experiment? we all know it doesnt work!

[Marcus B-T]

Why is such a large limb being taken off? Is there a photo?

Know, or have we been told? I think some more recent investigation into this type of work would be good. Its above my post but someone will know more than me. I mean look at how pruning has turned around. Target prunning was the only way we were told to prune trees then someone did some reserch and francture pruning has a better epicormic growth response.

MMMmmm fashion goes round in circles too, but you wont have me in flares again!
