The decision has been made to lop it to a less dangerous height.

My question is whether we should remove the tree entirely, or lop it.


If the safe height is below the second branching, then I would remove it
entirely and replant. If is shoots from the stumps where you lop it,
then is is just a dangerous sucker waiting to peel off.

The people behind up lopped major gum trees to a tall (20') stump, which
then just suckered at the top of the stop and grew for another 20' and
one windy day, they just started to peel off at the old stump level. New
growth at the old stump is not a proper branch, but rather a sucker that
can easily be peeled off.
