As Tree Care professionals, nearly every day we encounter issues that could have been avoided with proper planning. Having record of all your trees, their species, age, size and health history is the first major step to properly caring for a large property. Here at Emerald Tree and Shrub Care, we consider a tree inventory the absolute most valuable service we provide.

When you hire Emerald to conduct a tree inventory, we will send 1-2 (depending on property size) board certified arborists to walk your property with our state of the art inventory application. Using an aerial image of your land, they will pinpoint and ID every single tree they see.  Notes will be taken to document the species, age, size, health condition and recommended maintenance for each tree.

The inventory itself lives in the cloud, so it can be real-time updated by our arborists at any time. You will receive a link which you can access from your desktop, phone, or tablet.  From this thorough inspection and documentation, our arborists will be able to provide you a detailed scope of work for current and future tree care needs. Times when you will consider this inventory a true life saver include:

  • Planning new construction: If you want to build an addition or renovate an existing structure, this inventory will be crucial in planning for the installation of hardscapes, utility services and water and sewer lines. The inventory will also be used to develop a Tree Protection Plan to prescribe a regimen of treatments that will mitigate the stress experienced by trees during construction.
  • Landscape Design: What tree species should we add? Where will new plantings thrive? Will existing plantings be affected if we change the grade of our land? These are all important questions to consider when altering your landscape, and can all be properly addressed by referencing a tree inventory.
  • Changeover in Property Management: For large properties that require property managers, groundskeepers or superintendents, it is very important to have maintenance and health conditions well documented. A tree inventory would prove to be absolutely priceless when you have a change in property management personnel. An up to date record of all trees allows for a seamless  and well-informed handoff.

To learn more about our Tree Inventories and how they can benefit your property, please call us today at 914-725-0441 to schedule a meeting with an arborist today.

Black Knot: What You Should Know

What is Black Knot

Black Knot is a common fungal disease that typically attacks ornamental Cherry Trees and Plum Trees.  The disease is spread by infectious spores that can easily disperse through the air, on gardening tools and in spring rain.  Once a tree is infected, it can take a full year until the symptoms are fully recognizable with black tumor like growths appearing on the branches or trunk of the tree.  In late spring and early summer, these growths will become covered with olive green spores.  This is the time of year when the disease is likely to spread, but it is not always detected at this time, because trees are in full bloom and the bark is less visible.

How it impacts trees

The fungus itself is called Apiosporina Morbosa.  As it grows, it releases chemicals into the bark that causes the tree to grow extra plant cells that are extremely large. The growth itself will not kill your tree, however, the growths cause cracks in the bark, allowing other wood rotting fungi to enter and cause harm and sometimes death.

Early Detection and Prevention

Fall and Winter are the best months to inspect those ornamentals that are most susceptible to Black Knot and determine if an infection exists.  If detected early, an arborist may be able to prune away the affected branches and follow up with several Spring Fungicide treatments to prevent further infection from occurring.  A tree that was once infected, should be watched very closely, as it’s possible a growth could come back at anytime.


Because the disease is so easily spread, pruning should always occur in the Fall and Winter months when the spores are least active.  Also, infected branches should be very carefully removed from the property and all tools and equipment that came in contact must be sanitized thoroughly with rubbing alcohol. Fungicide treatment should be applied in the springtime right before buds begin to open. It’s a serious disease that is easily spread, so we highly recommend calling a Certified Arborist to diagnose and treat Black Knot. If you have Plum or Cherry Trees that you would like inspected, please call Emerald Tree & Shrub Care today at 914-725-0441.
