"They did a real good job. They were real professional. We can now open the garage door from the inside of the house and now it is so smooth that we have to check to see if we hit the button to open it or close it.  Before we used to know when it was opening or closing because it used to make a noise. It helps when you move to a city where you are new. "

Tree Service FAQs, answered by experts

A tree can grow back from its stump, but full regrowth is unlikely (especially for more stubborn conifer trees). Instead, trees are more likely to send up a number of shoots from the dead stump, which will try to develop into primary stems over time. In other words, it will start to look increasingly bushy. The goal of killing and drying out a tree stump is to prevent that from happening, as well as make the stump easier to completely remove.

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!

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.

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.

A grafted tree is a tree grown by combining two trees. It takes expertise. Branches from grafted trees don’t grow strong roots. Save yourself the time and frustration by having an arborist help you with this advanced project.  

You can often tell if a tree is grafted because it will have a noticeable line. Above the line, the bark will look different than it does below the line. It’s most common with fruit trees.
