"The young guy who did the work was prompt and professional, but not well trained. He power washed my patio BEFORE blowing the leaves and sticks off my roof, so all the debris landed on my just cleaned patio, and he didn't follow up to clean it off.
He forgot to do the garage door and was all packed up when he asked me to inspect, so I just let it ride.

"We had artificial grass we needed installed in our front yard. We had hired someone who stole our money. Fortunately my husband found Alonso doing a job in our neighborhood. Alonso came by and gave us a bid and started work the next day. He has a crew that are professional and hard workers.  They do very nice work and don't cut corners. Alonso was present daily.
When we had a question he answered the phone every time we called. This was refreshing . Alonso came through with work that exceeded our expectations. We now have the nicest lawn on the block, Thanks Alonso."

Arborists FAQs, answered by experts

According to scientists at Penn State University, spotted lanternflies do not typically kill the trees and plants they feed on, but they can cause branches and segments to die off. However, they have been found to kill cultivated grapes, which can have devastating consequences for vineyard owners and regions that heavily rely on vineyards to create jobs and generate revenue. They have also killed the Ailanthu altissima, known as the tree of heaven, though this is classified as a noxious and invasive weed tree.

Horticulturist is a broad term for any type of plant and soil expert. An arborist, meanwhile, specializes in all aspects of tree care. You should hire an arborist when you need assistance with tree-related tasks, such as pruning large trees, removing trees, diagnosing a sick tree, or emergency tree services. Horticulturists aren’t qualified to handle those types of tasks.

The best way to protect tree roots is to avoid the roots entirely by excavating outside the root radius of the tree. For nearby projects, it’s a good idea to construct a temporary retaining wall. But that’s not always possible, depending on the project and the root system. In these cases, consider using alternative equipment like an auger to tunnel under the ground.

Remember, tree roots can damage nearby cement foundations as they grow. If a tree is close enough to interfere with large excavations, it may be better to remove the tree than risk future problems.

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.

Tree roots can take weeks to years to die, depending on the method you use. Chemical herbicides take the least amount of time—typically between three and four weeks—while homemade methods, like covering an old stump with leaves, could take between seven and eight years. If you’re unsure which method to use or how quickly you need to act, consulting with a pro is always a good idea.
