light reductions

[David Humphries]

Big oak that took what I imagine is a sheet lightning strike 10 or so years ago.

 

There are dysfunctional strips running along the top side of the lowest laterals.

 

One popped off during high winds 7/8 years ago, & one delaminated at the union 4 years ago (we reduced this back to collar)

Now the lowest lateral above the footpath has delaminated along its top surface.

This had to be removed, so we've 'tickled' it back leaving it as a fractured stub.

Tearing into the collar that near a footpath...and this is not the Ecology forum...

 

Here's a tickle taken out of a liriodendron with a Humongous Hole (~50% circ., >80% hollow)mid-stem. All cuts to nodes that presently have laterals. left 2 lower limbs alone--not much impact on stability, and they nourish the woundwood around the canker.

Plus they were over the neighbors' yard and essentially their problem.

 

Lightens the load, c u in 3 years to restore. Prognosis: sprouting at cuts 1-2'/year, able to take off 1/3 next time to mitigate crowding and bad forks.

It could be..........let me toss a coin

Bit more than just a tickle.

 

Had it been reduced before?

well then better do it quick b4 folks get the wrong idea

mmm i've seen your gang scratch a lot harder!

Untouched by the hand of man as far as i know. had the helper climb (it was raining) but he did not report previous signs of pruning.

We've been known to scratch when there's been a big itch

 

 

The lirio 'looks' like it has a significant diameter shift (in the before shot) as if subjected to a re-iteration after a prune ?

 

Obviously Liriodendron is a native your side of be pond, but I don't recall our mature planted specimens here having that kind of crown framework?

That tulip's defo been pruned before:biggrin:

 

They don't grow like that normally...

 

 

 

 

EDIT: David put that much more eloquently than i did:lol:

pruned by saw or storm? the before shows central leader bent as if it was broken. trunk is riddled with cankers, not just the big cavity--no david no fb's seen.

 

i suspect the wind tore the top off, but i'll ask DJ to post the in-tree pics he got.

could've been lopped early on and that's how it got cankered. chicken or egg first?
