Can I cut Redwood Roots?
We have a 75 foot tall redwood in our yard 17 from the corner of our future (hopeful?) addition will be. There are large roots (6-8 inches diameter) running through the area. We were assuming they came from the redwood as they seem to run in the right direction. There is also a walnut tree nearby, as well as the possible root system from an apple tree that died a few years ago. From what I have been reading, it seems that the roots are too big to be redwood. Are they? If they are, can we cut them, put in a barrier, and build? Or will that kill the tree. Any information would be very much appreciated. Thank you all in advance.
