I couldn’t leave it alone! I want the new blackberries to do well, and it bothered me that the oak tree 50ft away was stealing nutrients from my raised beds. So I started digging. Glad I did, more roots than I imagined. The pic shows the trench I dug to break the roots. I have to go back and cut back the roots seen here so I can install root barrier

some of the roots were almost 2 inches in diameter.

this is the root barrier I’m going to use.

most interesting to me is the amount of energy the tree uses to grow horizontal roots near the surface. I would think growing roots deeper would be beneficial, but the tree chooses to burrow under concrete more than burrow down. I didn’t find any root below about 12″ of depth.
