It's what I was hoping to see, but I'm a little surprised by the time in terms of how long it's taken to notice the growth.

 

The tree is pretty vigorous."  Maybe the response would have been much stronger if the stub was not left.    Did you run into big sinker roots that stayed your hand?

Cutting off the interior sgr at the red line would have relieved much more constriction.  And would have allowed the blue root to remain.

Cutting at the orange line (what is that black crease--a partial cut?) would have been more sudden but not likely too much.

Hello guy, there's no text in your post above?

[David Humphries]

We had a look at a root girdle on a maple today that was adjacent to a single fruit body of the giant polypore (Meripilus giganteus) 

 

Good canopy vitality.

 

No significant decay of the contemporary root system by the Merip at this point (suspect the association is from a colonisation deeper underneath the old tap root system) but the girdle has constricted a couple of the buttress  roots.

 

The girdle is too developed to remove, so will adopt a watching brief on the vitality of the canopy and the associated buttresses.

Hi David,

What makes the girdler to large to tackle? Is it that the resulting wound would so large as to become colonised, that it would have implications for stability or impaired water/nutrient/air access? Could you pop off the one you've balanced your mallet on?
Ta,

Adam

Yes, it's the size of wound surface that would develop, as all the girdling root material is anastomised with the parent root system and would just leave no bark behind to protect the lower buttresses.

 

If any of the girdler was seperate from the parent material I would have considered removing it.

Thanks David. I've often wondered what the upper limits for pruning out girdled roots would be.

There was.  I did not understand your hesitation. "Maybe the response would have been much stronger if the stub was not left.    Did you run into big sinker roots that stayed your hand?

What makes you think it's grafted (anastomised, inosculated)? Looks like lots of bark in between. 

Red lines are obvious cut location possibilities, even if grafting is underway.  If the sgr wiggles a little it is not grafted and the orange line becomes an option.

It's really good to see someone in the UK get the dirt off the stem!  But perhaps you're a bit too shy with the tool.  Pruning wounds seal fast in that location ime.
