Advanced Technology & Tree Health Insights

We also have advanced technologies to offer you deeper insights into the needs of each component in your green spaces so we can more accurately care for and rejuvinate your property. 

Resistograph Technology

Our ISA Certified Arborists utilize resistograph equipment to assess the internal condition of trees. This non-invasive technology allows us to detect decay and structural weaknesses within the tree trunk, helping to make informed decisions about treatment, preservation, or removal.

Ground-Penetrating Radar (GPR)

We use GPR technology to create accurate root maps, allowing us to assess subsurface root systems without disturbing the soil. This is especially valuable for preventing conflicts with underground infrastructure and planning for long-term tree health.

Comprehensive Tree Inventory System

Our Tree Inventory System simplifies the ongoing care and management of trees. Each year, clients receive a printed folder with updated information about every tree on their property—including species, location, health status, and recommended care. This system supports long-term preservation planning and proactive maintenance.

5 star reviews

I was a customer of a major tree company that claimed to be the best in saving trees. I have a Magnolia Tree that was on decline. It was treated for 2 years and it never got better and it was deteriorating. A neighbor told me that I should give Emerald Tree a try, since they were doing an amazing job taking care of her trees. I called them and they immediately scheduled a free evaluation. They send the Arborist to inspect my tree the very same day, and the Arborist told me that the problem on the tree was misdiagnosed. Emerald Tree schedule a treatment for the very next day and only a week later the tree began to recover its vigor. It is incredible that I wasted so much time and money with the other company, but now I will only rely on Emerald, they are very knowledgeable and trustworthy. I highly recommend them.

My parents have been doing business with Emerald Tree Care for many years. They are great! They just completed a lot of work for us in September and had them back in October to remove a Willow Tree that was damaged in a storm. I couldn’t be happier with their services.
