"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."

"They are incredible! Julio is a perfectionist, him and his team are second to none! Besides all of them being completely professional and real gentleman's! They do my lawn, my gardens and mulching, tree work, trimming hedges, and beautiful masonry. I will never not use them unless I want to do something, but once you get spoiled using them you stop doing work yourself! Great company!"

Arborists questions, answered by experts

A tree can split because of high winds, a change in temperature, or from an infestation or tree disease. All of these factors can overlap, making a single cause difficult to pinpoint. While winter storms are some of the most common causes for a tree to split, it can also happen because of termites or rot.

Bradford pear trees bloom in early spring with small white flowers. They typically flower for at least two weeks. In bloom, these trees often emit a foul-smelling odor that’s often compared to rotting fish. Bradford pear trees will sometimes bloom in the fall due to drought or other stress-inducing conditions. 

You should avoid cutting off the top of mature cherry trees. This process is called tree topping, and it’s not recommended for cherry trees—or any trees, for that matter. Tree topping removes between one-third to half of the length of the tree trunk, resulting in structurally unsound, fruitless suckers. The only exception is for saplings. Young pie, sour, and tart cherry trees that are over 30 inches tall in the fall or winter before the tree blooms can benefit from heading cuts.

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.

The felling notch you make before you make the final cut will determine which way the tree will fall. The cut will be in a wedge or triangle, and the tree will fall from the highest point of the triangle. You can use this, as well as the process described above, to estimate where a tree will fall.
