Sissoo trees, a.k.a. Indian Rosewood trees, were popular in Arizona decades ago. Fast growing, creating little mess and great for providing shade, the Sissoo appeared to be perfect for Arizona. The wood is commonly used for furniture and musical instruments. Native to India, the extensive root system is beneficial in preventing erosion of the local riverbanks.
Over the years, it became apparent that the root system invaded sewer pipes and water lines, lifted foundations, sidewalks, driveways and destroyed swimming pools. There have been lawsuits over the damage that Sissoo trees have caused to neighboring properties. The roots and the suckers have been found up to 180 feet away from the trunk. Sissoo trees are currently listed in the 100 Most Globally Invasive Species List. This otherwise attractive tree eventually becomes destructive due its root system searching for water. The question is not if it will cause damage, but when it will cause damage.
Simply cutting down your Sissoo won’t kill it, unfortunately. Cutting it down and spraying the stump won’t kill it. Owners have spent many thousands of dollars over years repeating the ‘cut and spray’ method to no avail. You can prevent or reduce damage, by beginning our treatment now.
What is our treatment? It’s a chemical herbicide injected directly into the living tree, allowing its own circulatory system to move the herbicide throughout the entire tree and roots. While most trees are destroyed with the first injection, occasionally a second injection may be required. Then, we cut the tree down and the remaining stump is injected with herbicide to ensure the destruction of the root system.
The overall process takes approximately four months. During that time, we’ll have a Certified Arborist revisit your tree to monitor progress. We know you’re busy! We’ll take control of the process leaving you to carry on with your life. We’ll call and/or email you to schedule the visit at the appropriate time and update you on the progress.
If you live in a Homeowners Association, they may not be happy with the appearance of a dying tree. But we’ve got you covered! We’ll provide a letter explaining that you’ve begun the process. We’ll give an approximate date of when the tree is likely to be cut down (after it’s confirmed to be dead) so you can ask the Association for a variance while you have your invasive tree treated.
