Whether tree roots will continue to grow after a tree has been cut down depends on the species. Some tree roots will eventually die because they can no longer get nutrients through photosynthesis. However, other species that reproduce through root sprouts can continue to grow and produce new sprouts for seven years or more. For example, the roots of elms, ficus, and willows tend to regrow aggressively, while the roots of pines, oaks, and maples will typically die. To determine if a root system is still active, look for new sprouts on the old trunk, stump, or any exposed roots.

Palm trees are unique in that their roots don't grow straight down; they grow horizontally. Typically, palm tree roots go down between 12 and 36 inches deep. The roots grow far and wide from the base of the palm tree to absorb as much water and soil nutrients as possible. In addition, the horizontal roots are also very strong—keeping palm trees stable and helping them sway during storms.

Tree removal can be quite expensive, especially for larger projects, but you can use the following tips to help keep costs down:

• Do the yard cleanup afterward yourself

• Choose to leave the logs on your property and split them yourself

• Opt to leave the stump in the ground and tackle stump grinding yourself

• Pull permits for tree removal, if necessary, to avoid fines

• Pay to have multiple trees removed at once

• Remove tree in the late winter or early spring during off-season

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.
