Q.Tree roots
There are many tree roots that have extended into the flower bed and we are trying to identify which tree they are coming from. The roots are coated with a thin red bark. Nearby trees (between 10 and 30 feet) from the garden are pine, crape myrtle, and oak. Do you know which tree the roots may be coming from? Thanks for your help.
Pine Tree roots can travel 2 to 3 times the width of the drip line.
Pine Tree's are known to have invasive roots and most of the roots are within the top foot of the surface.
A Crepe Myrtle root system in fibrous and close to the surface.
Oak Tree roots have a tap root and the majority of roots lie within the top 18 inches of soil. The roots can occupy the space 4 to 7 times the width of the trees crown.
My best guess is that you are seeing the Pine Tree roots.
