Large Oak reduction help

[Tony Croft aka hamadryad]

Nice one! dont forget to top up the mulch everyyear, thats a good job!

 

your fungi is Bjerkandera adusta, though B. fumosa also possible

Cheers Tony. Mulching along with general remeidal works planned annually. We both felt quite a bit of satisfaction and well chuffed even after just a bit of mulching today. Just nice to give something back to the old girl.

Good Stuff Ian.

Looks like you did the very best with a bad situation--nice work! Was the bracing digging in yet? That's the issue with dynamic/cobra; high maintenance compared to steel.

 

Glad to see the heavy reduction was not done; the rot would likely have gone wild, and the tree would have been ugly forever, and high maintenance.

 

Q rubra common where I come from; dying out in its native range from root rot. Acidification of the atmosphere and thereby the soil is blamed. they tend to single leader; that one must have been whacked early. Those features in the leaders--bulges and ridges etc.-- look more like adaptive growth, signs of reinforcement rather than failure. from x,000 miles away anyway...

6+ cubic meters of roots dug--disastrous wounding and loss--TPO should include the bottom half of the tree too!

 

re introducing compatible mycorrhizae, one idea is to spread chips under the same tree.

 

Topping off the mulch can be overdone--attached pics show slabs of sterile old mulch exhumed after it smothered roots below. no that would be a derail; i'll start another thread.

 

Looks good in the end--thanks for putting up the pics!
