Not a whole lot you can do. You didn't state what kind of trees you
have. Some trees have tendencies to grow surface roots, such as
willow.

Correct, a willow is the main culprit, though there are a few other trees
that I cannot readily identify.

I suggest a circular layer of organic mulch, mushroom compost is my
favorite. You can plant a shade garden--impatients, pachysandra,
ferns, etc.

Thanks, I may consider this. It is impossible to mow there, and the kids
keep tripping over the roots when they play, so it might be best to plant
something shade-loving and just forget about grass.
