I've asked this question already here: https://diy.stackexchange.com/questions/88497/dead-tree-how-to-stop-rotting
But realise now it should have been asked here.
I have a very large eucalyptus tree. I have recently been told by at least two tree surgeons that the tree is dying and should be taken down.
Its a beautiful tree and very large and does present a safety risk. I can see that part of the base of the trunk is crumbling, however above the crumbling area it all looks good. We have decided to have the tree removed leaving about 12 foot of the stump.
The question is, is there anything I can treat the crumbling area with to harden it and stop it crumbling further? I'm not looking to save the tree, but I would like to carve the trunk into something but would need to harden it first.
