Can I substantially reduce the height of a large holly tree?

Saving a lopsided Douglas fir from needing to be removed

What kind of tree is this? And how can I kill it?

Will cutting away root(s) of a tree growing under my basement floor kill it?

If you cut the tree down you don't need to remove the roots. They will die and decompose naturally in a few years. Assuming the roots under your house are in complete darkness, nothing will grow there ...

Why do tree cutters cut the limbs of the tree before taking down the trunk?

A tree with its branches weighs a surprising amount, usually much more than someone not in the trade thinks. In addition, branches can act somewhat like sails if a tree is taken down with all of its ...

What can I do with a large, old tree?

The ivy isn't helping matters. It will eventually girdle the tree. Additionally it is adding weight to the crown, and acting as a sail, especially in the winter when the tree isn't used to having ...
