"We had some scheduling issues at first but they did come by and do the work. They did keep in touch with us until they could come out. They did a good job helping us clear an area of the yard. Two people came out and completed the work in 2 hours. They were nice guys.We were looking to have someone to a monthly lawn service but they had some change going on in their company and were not able to continue service with us."

Arborists questions, answered by experts

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.

Some trees, such as silver maples, birches, sycamores, and scotch pines, shed their bark naturally. If your tree is not one that does this, it might have fallen prey to pests, fungi, or diseases. It could also simply be suffering from an extreme weather change, such as a snowstorm or heat wave. If you’re still stumped, consulting with a pro can help you diagnose your tree’s specific problem.

A few signs a tree may be dead is if the leaves are dead and there are no signs of new blooms. You can also perform a scratch test on some of the branches to check the condition of the cambium layer beneath the bark.

If it is green, it is still alive, but if several are dry, brittle, and brown, the tree may be dying or dead. Always consult an arborist before assuming your tree is dead because you may be able to save it.

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. 

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.
