Ya know, your right, concrete is strong, who knew. But since u have no idea of what it really does to a tree, what ants do to a tree. I am going to ask you to get some education in Arboriculture, because it is obvious that u don't have any. These things that u say have been proven wrong (except that concrete gets hard) by so many, its amazing that you haven't read about it somewhere, but it is clear that u have not. Keep posting absolute BS and you will go away. Your "advice" is horrible and not accurate.
Just so no one takes away, any of this he says. If a tree needs to have a yard of concert poured in it, it should be removed, period. Yes at one time in history, it was a practice, then we started walking upright and making wheels.
Do you work in tree care?
do you have common sense ?
show me a tree that fell over, because there was concrete in it.
this thread OP showed one thriving, that would have fallen down a long time ago, had it not been for the concrete blocks
cutting them down, isn't tree care.
anyone can do that. If your idea of "tree care" is cutting them down, without hitting anything, I'd say it's lacking.
making them live another 100 years, now that's the challenge
ever hear of the liberty tree ? It lived another 90 years, because it was strengthened with concrete

the Liberty Tree
THE LIBERTY TREE
A famous tree once saved with concrete in 1907
was “The Liberty Tree,” in Annapolis, MD. This majestic
Tulip Poplar (Fig. 4) eventually lived an estimated
400 years—100 to 150 years beyond the normal life span
for the species. Unfortunately, damage from high wind
forces exerted during recent Hurricane Floyd harmed
the old tree too severely, requiring its removal in 1999.
Taking out the concrete-filled arbor proved an arduous
task—requiring a laborious day and a half. It was a
sad ending to a natural monument that had withstood
many assaults during its long life, including lightning
strikes, fire set in one its hollows, and even a blast
from 2 lb (0.9 kg) of gunpowder placed within a hollow
in the old tree.
The Liberty Tree earned its name for events taking
place under or near its once capacious, leafy awning
during the American Revolution in the 18th century.
At the time, these events included meetings at which
orators fomented revolution against the British Crown.
One such speechmaker was Maryland=s Samuel Chase, a
founding father of the United States of America, and a
signer of the Declaration of Independence.
Over the many subsequent decades, the tree and
its environs hosted picnickers, religious sermonizers,
sporting events, and even ceremonies for the graduating
students of St. John=s College, on the campus of which
the Liberty Tree had resided. In the early part of the
20th century, however, the extent of the large cavity (due
to parasites that had excavated into the tree) became
quite serious. The damage had reached 56 ft (17 m) up the
interior of the tree. Remedial surgery took place in 1907,
when a landscape architect, forester, and tree surgeon,
John T. Withers, cleaned out the tree=s enormous void.
He followed with antiseptic treatment and then filled the
cavity with concrete, using sections of iron and steel
for reinforcement. The Liberty Tree required 55 tons
(50 tonnes) of concrete—reportedly the largest case of
tree surgery ever performed.
Although the famous old tree did succumb finally, it has
experienced a sort of metamorphosis. After being torn
down, its sturdy wood was sold to a guitar manufacturer,
who converted it to 400 “Liberty Guitars.”
