Straw Mulch on New Grass: Leave It or Remove It?

Straw used to cover newly seeded grass should be left in place. It will decompose naturally, adding organic matter to the soil. There’s no need to rake it off in fall. If desired, you can lightly rake in late spring after the grass is established and has been mowed a few times, but it’s not required. Continue watering regularly through late fall to support root development.
