Question 1

How do I know when a tree needs trimming?

Accepted Answer

•

Sometimes, knowing when you need tree-trimming services is straightforward, and other times, you have to do some investigating. Some tell-tale signs that you should have your tree trimmed include:

A poorly-formed tree with unruly branches, which makes the tree appear odd-shaped.
A tree with tall or large branches that interfere with power lines or your home’s exterior.
A tree that provides too much shade in the yard due to branch overgrowth.

Question 2

How do you hollow out a tree stump?

Accepted Answer

•

There are several methods to hollow out a tree stump, and the best one depends on your tools, experience, and priorities. Common methods include using a chisel and hammer, a chainsaw, or burning.

Chisel and Hammer: This is often considered the easiest approach for those with limited tools or experience, though it is the most time-consuming.
Chainsaw: Using a chainsaw is the fastest method, but it comes with significant safety risks, especially for inexperienced users.
Burning: This can be an effective method, but it is not recommended unless you can first drill holes into the stump. Without holes, the stump will be difficult to light and may not burn completely through.

A power drill with at least a ⅜-inch diameter bit can make the job quicker and easier, regardless of the primary method. While you can use a chisel or chainsaw without a drill, it will require more time and effort. Always wear protective goggles and thick gloves, as splinters are an inevitable risk.

Question 3

How far should trees be from foundation?

Accepted Answer

•

In general, trees should be planted no closer than 15 to 20 feet from your foundation. For larger trees with far-reaching roots like maples, oaks, or poplars, a good guide is to plant as many feet from your home as the tree’s height is expected to reach at maturity. Some trees, like elms and willows, should only be planted far from where their roots may encounter sewer or water lines.

Question 4

Can I cut exposed tree roots without killing the tree?

Accepted Answer

•

Carefully pruning small roots no thicker than three inches in diameter won’t harm the tree. However, cutting larger roots may impact the tree's stability and nutrient absorption. It's advisable to consult an arborist or tree care professional to evaluate the root's size, the tree's health, and the potential impact of cutting. Proper tree pruning techniques and timing can minimize damage, but larger root removal may necessitate expert guidance to avoid compromising the tree's overall health and stability.

Question 5

How do you protect tree roots during excavation?

Accepted Answer

•

The best way to protect tree roots is to avoid the roots entirely by excavating outside the root radius of the tree. For nearby projects, it’s a good idea to construct a temporary retaining wall. But that’s not always possible, depending on the project and the root system. In these cases, consider using alternative equipment like an auger to tunnel under the ground.

Remember, tree roots can damage nearby cement foundations as they grow. If a tree is close enough to interfere with large excavations, it may be better to remove the tree than risk future problems.
