No, you cannot throw branches from your neighbor’s tree back into their yard, nor can you discard leaves or other plant matter that originated from their yard back over there if it happens to land in your yard. You are responsible for cleaning up plant matter that made its way into your yard.

There are several signs that may indicate a tree needs to be cut down. These include visible damage to the trunk or branches, a hollow trunk, extensive storm damage, or a significant lean to one side. Other warning signs are pest infestations or the tree growing too close to a house, power lines, or other structures. It is best to hire a professional arborist to inspect the tree, as they can determine if it can be saved or if removal is necessary.

It depends on the problem, the affected part of the tree, the risk of the pathogen spreading, and the overall health of your tree. Many diseases, fungal infections, and insect infestations can be successfully treated, especially if the issue is only in a few branches. However, if a disease is too widespread, too severe, too easily spread, or in the roots, the tree will likely need to be removed.

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.
