How long should you leave straw in your lawn before mulching?
The straw should be left in place until the new grass grows to a height of about 3 inches. Depending on factors such as temperature, humidity, and soil type, this can be anywhere from three to five weeks. Mulch should be at least one-half to two-thirds of the total area of your lawn. If you have a lot of grass, you may want to use more than this.

What happens if you leave straw on top of grass?
