Grass Planks and Other Aesthetics/Functions

There should be an option to mulch grass planks, my base is getting littered because I keep having to cut down new growth. Another suggestion: salt to prevent growth. OR, it could just despawn after a while. I know there are already headaches about the dew collector and mushroom patch though. The mulch could be used to farm different resources like grass, mushrooms, weeds, clovers, etc. You could get the salt from a salt shaker or deposits around the yard, as well as use salt to cure meats to last longer.
