Blackberry tree roots

Asked October 1, 2019, 7:22 PM EDT

I have a Blackberry tree in my backyard, I had a couple of cracks in my wall foundation that caused water infiltration into my basement and it ruined my floor and part of my walls. I wonder if the roots that is ~4” in diameter and some on the surface, that extends to the house in much smaller diameters can suck the water from the soil underneath and consolidate that caused settlement at the corner of the house that could of caused the cracks around. 20’ from the corner in each wall

Thank you for your question. I am unable to find any plant called a "blackberry tree." Blackberries are canes, and have relatively small root systems; certainly not big enough to cause a foundation invasion. Could you please check the species, and let us know what it is? Your location would also be helpful.

Here are a couple of Extension articles on roots and foundations: https://hort.ifas.ufl.edu/woody/root-system2.shtml

Sorry, it’s a Mulberry tree not blackberry tree

Mulberry trees have wide, aggressive roots known to clog drains: https://www.oardc.ohio-state.edu/weedguide/single_weed.php?id=77 Unfortunately, we are not engineers, and cannot give an opinion about whether they are able to compromise foundations, more than the information I referenced in my previous answer. Good luck!

Thanks a million
