In most cases, leaving tree roots underground is not a problem if the stump has been removed or ground below the soil. However, some larger roots may decompose, leaving dents in your soil. Additionally, some aggressive trees, including willows, oaks, elms, maples, and poplars may grow back from roots. Large aggressive trees with established root systems are more likely to grow back.

It can be bad to leave a dead stump in the ground. A stump becomes a hefty piece of dead wood in time and eventually (especially with the help of rain) starts to rot. That makes it a locus point for diseases and pesky insects, as well as a bit of an eyesore. It’s best to remove a tree stump completely before it starts to decay, especially before it starts to fall apart. If the tree was removed because of disease, it’s even more important to fully remove the stump if possible.

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.

In most ways, palm trees are incredibly low-maintenance. They don’t need a ton of water—which is why they’re so beloved in desert regions—and they basically prune themselves. But they do need an ample supply of sunlight and to be in soil that will allow for proper drainage so that their roots don’t become waterlogged and at risk of developing illnesses.

If the plant begins to wilt, develop spots, or change color, these could all be signs that your palm tree has a disease. But a few basic treatments, like pruning and applying fungicide, will usually be more than enough to return it to perfect health.
