"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."

"Joel and his team did an excellent job on our spring cleanup and mulching. They were very hard working and paid great attention to detail. Everything turned out better than expected. They have also began to mow our lawn weekly and have been great. The pricing is very reasonable and I highly recommend to anyone in the area."

"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

If you aren’t sure what you’re doing, be very careful when cutting mature tree roots (roots larger than 2 inches). Root cutting and pruning can affect both a tree’s stability and its ability to nourish itself. Issues during root cutting can result in damage or injury. 

It’s recommended you call in a pro to help, unless it’s a very small tree and you aren’t worried about the prospect of losing the tree.

Bleach can potentially kill some types of delicate ornamental trees, but for the most part, it will only kill the foliage it comes in contact with. Applying bleach is not an effective method of killing a tree. A better option is to use an herbicide, which is a chemical compound designed to effectively kill a tree. 

If a tree isn’t pruned, it can inhibit proper growth and fruit production, cause damage to both the tree and your property, and create entry points for pests and diseases. Pruning a tree enhances its stability, appearance, shape, and growth. Pruning trees regularly can also save you money long-term by avoiding overgrown or dangerous dying trees.

The best time to trim trees is in late fall through winter when the tree has slowed its growing for the year. Cold weather stops insects and fungal growth from attacking a new tree wound. Summer and fall are considered the worst times to trim trees, but it’s permissible in certain scenarios, such as tree disease, damaged branches, or small, aesthetic cuts.

You can find pruning paints and sealants for trees, but you shouldn’t use them on a topped tree. Coatings like these often inhibit the tree’s healing process. An important exception is if there are dangerous fungi nearby that the tree is particularly vulnerable to, like oaks and oak wilt. Sealing cuts can help prevent fungi from taking root.
