Maple tree roots
I have maple trees in my yard and the roots are above ground. Getting larger every year. I'm concerned someone will trip on them. What can I do? Thanks

These are called 'surface roots' and maples are one of the more common trees that do this. Purposefully cutting them, or shaving them accidentally with the lawnmower is not good for the tree.
Part of the answer is to suss out why they are showing.

While you can add soil (if there has been erosion) or mulch over top of them to level things, it can't be very deep as the roots need oxygen. Mulch or even a shade-loving groundcover should help keep pedestrians away.
