How often and long you should water a tree depends on the species and if it is mature or newly planted. The amount of water is also based on the tree's size. A good rule of thumb is approximately 5 gallons per inch of the trunk's diameter.

Adjusting watering to the recommended suggestions for the tree type and weather conditions is vital. For instance, watering trees during a drought is necessary, and you may need to water more frequently than usual.

Your neighbor is not in a good position to know if your trees are truly dead or pose any kind of danger. That’s why hiring an arborist or tree service expert can be such an important part of the process. If the trees are still alive and don’t pose any threat, you’re in the clear (but you may want to document and photograph everything in case events turn sour down the road).

But if a tree is visibly dead and near the property line, you should remove it to be safe. If a dead tree falls on a neighbor’s property, they may have grounds to sue for negligence. If any branches on trees have died, it’s a good idea to cut them back for similar reasons.

If you’re wondering whether you can plant a tree where the stump was removed, know that the soil conditions won’t be ideal, so you should avoid it. The soil beneath the previous tree will likely be depleted of nutrients, plus there may be roots left behind that will seriously hinder the growth of a new tree. Also, if you use salt or other chemical solutions to kill the stump, these can linger in the soil for months or even years and prevent healthy growth. It’s best to choose a different spot that’s at least three feet away for a new tree, or wait at least a year and thoroughly amend the soil before you plant.

You may wonder whether tree removal is tax deductible: Tree removal is not tax-deductible for homeowners unless it's related to a federally declared disaster. In that case, the cost may qualify as a casualty loss. However, if you own a commercial property, like a rental home, tree removal could be deductible if it's necessary for safety, maintenance, or part of a larger capital improvement project, and you must hire a professional tree removal service and keep documentation. Always consult a tax professional beforehand to see if you qualify.
