Question 1

Do spotted lanternflies kill trees and plants?

Accepted Answer

•

According to scientists at Penn State University, spotted lanternflies do not typically kill the trees and plants they feed on, but they can cause branches and segments to die off. However, they have been found to kill cultivated grapes, which can have devastating consequences for vineyard owners and regions that heavily rely on vineyards to create jobs and generate revenue. They have also killed the Ailanthu altissima, known as the tree of heaven, though this is classified as a noxious and invasive weed tree.

Question 2

When should a leaning tree be something to worry about?

Accepted Answer

•

Not all leaning trees are dangerous, but they can be a hazard as gravity may eventually cause them to fall. A key factor is whether the lean is new or has been present for a long time. Trees that have grown with a lean for years are not typically an immediate danger, but a sudden lean is a cause for concern as it often indicates weakening roots. If a tree is leaning more than 15% from vertical, you should consider having it straightened or transplanted. To be safe, it's always best to hire a professional arborist to inspect any leaning tree to assess the risk and avoid potential accidents.

Question 3

How far down do tree roots go?

Accepted Answer

•

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.

Question 4

What do I do with a tree stump once it’s dead?

Accepted Answer

•

Some people prefer to leave or even carve a leftover stump, but we recommend removing it if possible. You can often dig out smaller trunks with a shovel once they have died and dried out. You can have stumps professionally removed, or request a service to grind them down to ground level so they can be replaced with other landscaping or objects.

Question 5

Do I have to grind an old tree stump?

Accepted Answer

•

We recommend removing the stump, and grinding is a popular way to do it. You can also dig out small stumps or stumps that have fully decayed instead of grinding them. However, don’t try using acids or fire for killing a tree stump, which is a fire hazard and illegal in many areas.

Leaving the stump alone invites eventual problems, including attracting termites, mold, and fungi.
