Would anyone have recommendations for what type of mulch/rock to use in yard that has many trees that lose LOTS of acorns, hickory nuts, leaves and small twigs? I can't seem to come up with any ground cover to edge the house and garage that would allow me to rake up all the debris that falls from the trees each fall. Anything too light gets raked up when I try to rake out the leaves, acorns, and hickory nuts...anything large (river stone) has so many voids between the stone that the debris gets lodged and won't rake out. What should I do? Thank you!
