One UK muni pruning job

[guymayor]

Laetiporus hollowed the trunk up and down, which is why all that green came off, losing some of the natural habit. But symmetery is a good thing, and i have no doubt it will regrow favorably.

Re the coronetted 'stubs'; A cut right back to the upright lateral would have dried the wood and sped decay in the tree structure. The extra wounding at the end of the 'stub' creates the habitat, which was part of the objective, while allowing a 'collar' to form to conserve the structure.

I may do it here in the US, as soon as that habitat is desired by an owner or client. I'm not holding my breath on that one...

Well very interesting Guy. Of course if we didn't know you already we'd think that was the worst tree work we'd ever seen. But I personally am going to sit back and watch and hopefully learn more.

We've been taught, forever it seems, to make the smallest wound possible so as to heal the most rapidly. Yet here, they're mangling the ends being cut off. If I understand the premise correctly, this is being done to hasten the rot in that area, while allowing a collar to form further back, where a future "proper cut" will be made?

Sounds crazy. But I won't lie, I'm tantalized by the idea of it, if it works. And I'll be the first to say I was wrong if you'll show us some proof later.

I still having this nagging notion though that what's being done is akin to a keeping a dead body on a respirator forever.

Thanks for keeping us thinking outside the box.
