Good morning! We have discovered this summer a super invasive bright orange root system in our yard, garden, and under a patio we pulled up. It appears to be a tree root system but all of our searches have not let us to the offending tree. We thought it might be a Mulberry tree but can’t find one large enough to have caused this extensive system. We have found smaller trees that appear to be mulberry. It seems to be running under our house, fences, everywhere. We found a lot of small bright orange roots and bundles of roots in a raised garden bed installed 3 years ago, so a lot of the growth has been recent and most large roots pulled up appear to be very healthy and still growing. Any help in identifying and control to stop further damage would be helpful!
