Question 1

When should I schedule an arborist to prune my tree?

Accepted Answer

•

Ideally, you should wait to prune until trees have gone dormant in late fall to early winter. The worst times to prune trees are early fall and late summer, as pruning them so close to dormancy makes it difficult for the tree recover before it goes dormant for the season.

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

Can I take down a tree myself?

Accepted Answer

•

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.

Question 4

Will a palm tree regrow from a stump?

Accepted Answer

•

Palm trees will not regrow from a stump once the tree has been cut down. This type of tree is unique because the root and stump system will slowly decay after the tree is gone, unlike other species that can regrow. That’s why it’s preferable to remove dead or decaying palm tree stumps quickly as they can become an eyesore and don’t offer future growing potential.

Question 5

Does Dutch elm disease affect other trees?

Accepted Answer

•

It’s not as common for Dutch elm disease to affect other types of trees, especially if the surrounding trees aren’t elms. However, it is possible for DED to spread to other trees, particularly in northern states, like Minnesota. In fact, it’s a good idea to use geography to identify wood and determine which types of trees are in your yard.

Unfortunately, the complex and shallow root system of elm trees makes surrounding elm trees particularly vulnerable to DED. Early discovery is key!
