Whether you should remove the roots of a dead tree depends on whether they’re damaging nearby areas. For instance, if the roots continue to grow near sidewalks, driveways, or the foundation of your home, they can cause damage. If you want to plant something else in that spot, removing the roots can make it easier for the new tree or plant to grow.

Leaving the tree stump and letting it rot is never a good idea, as this leads to insect infestations and other frustrations. Additionally, decomposing trunks are at risk for diseases that spread out to the remaining plants and trees in the yard, thus ruining your whole outdoor aesthetic. It's usually best to remove the stump at the same time you remove the tree.

You should not trim an oak tree in the summer. Oak trees are especially susceptible to disease, and open tree wounds are an invitation for beetles that carry tree-killing fungus. If there’s no risk that the oak tree will do damage to your property or hurt someone, it’s best to save the trimming for fall or winter. If you can, seal the wound with latex to prevent fungus from getting inside.

Unfortunately, if you cut the top off a palm tree, it will die. Instead of budding or branching out, the top begins to slowly rot. That's why having a professional tree trimming at least twice a year is a good idea. If you don’t have experience with trimming your palm tree, you might accidentally cut the top off, leaving a dead and rotting tree in your wake.
