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.

You can use the formula mentioned earlier to calculate the depth of tree roots. Each inch of width of a tree trunk translates to six inches of depth within the root system. Large trees extend anywhere from 2 to 6 feet into the ground, with some magnificent specimens going even deeper.

Trees naturally want to grow upward, so one may straighten all by itself, though this only comes into play when a tree is leaning just a small amount. For trees growing into an awkward position or those leaning heavily in one direction, the above steps are necessary to ensure the tree gets back on the right path. This also holds true for trees planted in a spot with unstable soil.

It is possible to cut down a tree on your property yourself, but it is generally not recommended unless specific conditions are met. You should only consider this project if the tree is small (e.g., under 4-5 inches in diameter and short enough that you don't need a ladder to reach the branches), and you are experienced in handling a chainsaw. The tree must also be located far from any power lines, fences, homes, or other structures. Even for small trees, the work can be dangerous, and it's always advisable to have a spotter to ensure the tree falls correctly and no branches fall on you.

For any tree that is large, requires a ladder to access, or is near electrical lines or structures, you should always hire a professional. Attempting to remove a large tree yourself is extremely dangerous, poses a risk of serious injury, and could result in significant damage to your property.

Before any tree removal, it's also important to check your local and state regulations to ensure the tree is not historic or otherwise protected by your city.
