Managing Trees with Decay & Dysfunction

[David Humphries]

Spent ages last night trying to find a shot of fruiting Armillaria on birch & associated bleeds.

 

Could I find one where I would of presumed to have it stored

 

Anyhoos, found one lurking in a random folder this morning.

 

 

 

No management with this one, it's deep in woodland

its a bit of a mare this folder business aint it, you know their there but where be there!

"Gotta love the attempt, I mean how big was this wound guy?

 

31" above grade, continuous.

 

"Q. rubra is particularly prone to honey,

 

What evidence or fact brings that in at this point?

 

"and doesnt cope well with pruning wounds.

 

Pruned 2 years before; visible closure. Not sure anyone can generalize to that detail. This basal wound in the sinus indicates the only wounding may be included bark between buttresses.

 

"How much die back was present in the canopy?

 

None. Crown not dense, not thin. David, cauterization seems like a logical practice, on waterborne buggers in particular. Bartlett in the UK may be researching it on horsechestnut at present.

Guy, I remain open as always, my hands and mind, "I see you" but how can you expect to treat these bleeds this way? what is your thinking, how did you come to the conclusion this would benifit the trees natural sealing proscess?

 

why did you not just do soil amendments decompact ect?

[David Humphries]

Like the idea of removing girdling roots

 

Inspired me to have a closer look out for this issue and see whether there are many butresses that are/have become dysfunctional due to it.

 

 

Guy, thanks for the shots. Can you explain the process of cauterizing a little more please?

as do I but when do roots that cross each other become girdles as opposed to grafts and soil locking points?

 

great care will need to be taken in this route.

When the constriction has a bearing on the vascular flow.

Well duh, as the kids say. It is almost that simple; details in attached 3. I'll take more pics by tomorrow, and try youtubing the cauterization and other treatments.

 

What are "soil locking points"? And what type of great care do you recommend should be taken with root pruning? Shigo cautioned on this but frankly that was without much--any?--experience, and no research.

 

Why not just be satisfied with phosphite drench and soil works? Because they do not always work, and...the ooze appears infectious, so it seems neglectful in a way to just leave it. And, the tissue that's been killed blocks the way for treatments to reach the active infection, so why just leave it there? It's not helping the tree any more.

 

Attached 1-2004 reviews cleaning and drenching but not cauterization. 2-2010 does. Both went to 20,000+ without *any* negative feedback, fwiw. O and David i hope the early note on diverse = sustainable street tree plantings makes sense in 2; the invisible hand of a sustainable plan.

the ooze seems infectious! oh boy

[Fungus]

Shigo ... without much--any?--experience, and no research ... and...the ooze appears infectious, so it seems neglectful in a way to just leave it.

 

Now there's some high quality scientifically based research we have our ears slapped with . Listen and learn, all of you ignorant and tree surveyors : whatever is causing the black flux, oozing is infectious or maybe even contagious !!!
