Do not cut it way back. Oak trees may be killed if you take more than 1/3 of
it. You need to find out why the limbs are dying, is it diseased by fungus
or a virus or does it have an infestation of bugs.

Contact an licensed arborist!

I have an oak tree at the back of my house that is dying. Each year a
couple of branches are drying up. What can I do to save this tree?

Thanks.
