DETERIORATION
run to seed and go to seed
to become worn-out and uncared for. (Said especially of a lawn that needs care.)Look at that lawn. The whole thing has run to seed.Pick things up around here. This place is going to seed. What a mess!
wear and tear (on something)
the process of wearing down or breaking down something. (Fixed order.)Driving in freezing weather means lots of wear and tear on your car.
I drive carefully and sensibly to avoid wear and tear.
