Roots of almond tree

Asked April 7, 2020, 3:35 PM EDT

Hi, I am preparing to plant a Halls Hardy Almond tree and want to know about its root system. Is it ok to plant one of these over utilities? And if not, how far away from the lines is good? Many thanks!

A standard Halls Hardy almond tree grows to about 15-20 ft height, and based on research out of the University of California, we know that the roots of almond trees can extend more than 2 times the height of the tree. Most of the roots are not very deep, but horizontal roots that extend out from the base of the tree, but the trees also send down some deeper sinker roots. Based on this information, I would suggest planting the tree at least 40 feet away from any underground lines. If you don’t know where the lines are located on your property, you can call your utility company or the Oregon Utility Notification Center at 811 or 1-800-332-2344 (toll-free) and they should be willing to either provide a map or come out and flag your property. They may have specific regulations for planting next to utility lines that would be worth inquiring about.
