"I needed invasive vines and poison ivy removed from areas around my property.Matt went over the whole job with me and explained the way he would do it and assured me about the safety of his method. He even noticed something that needed to be be treated on a magnolia in my yard. He arrived the next day and did the job quickly and thoroughly. Hi price was more than fair. The fact that he was a licensed arborist and had other certifications was doubly ressuring."

"Louis and Julio were excellent. They carefully fell about 10 trees on my property and placed the logs exactly where I requested and sized them carefully. They were able to take down a dead tree and leave the one below it without damaging it, something I was very concerned about. They hauled away a lot of punky wood in their beautiful new Mack truck. Before the project began, we walked the property and they marked the trees and rotted wood with red tape which made it clear exactly what I needed done. I will definitely use them again!"

Arborists questions, answered by experts

A tree branch should start to form roots in about three months. It can take about a year for a tree branch to develop roots strong enough to go in the ground. For best results, start several branches because, no matter how closely you follow instructions, they won’t all form roots. Compost any that aren’t thriving.

In most cases, your neighbor is responsible for roots from their tree that cause damage to your property. If your pavement, the foundation of your home, or a fence is damaged by roots from a neighbor’s tree, you likely will have legal recourse for financial relief. While it’s better to notify your neighbor of any problems you notice as soon as they arise to avoid costly damage, there are some instances where filing a civil suit is your only recourse. Your homeowner’s insurance company might wish to do so on your behalf if you file a claim.

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!

If you don’t cut down a dead, dying, or diseased tree, it can become a nesting place for pests like mosquitos, bees, beetles, wasps, fly larvae, and more. Some pests will live in the tree, while others will feed off the decaying wood. Unhealthy trees are also more likely to fall over, potentially injuring people and causing damage to your property.

Tree roots don’t necessarily break through concrete on their own, but they can certainly take advantage of existing cracks, even very small ones. As roots grow, they expand the cracks, making them larger and leading to serious and costly foundation damage. It’s a good idea to have repairs on any foundation cracks you’re concerned about.
