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.
How do you get rid of straw in your lawn?
You should remove a straw blanket from new grass after four to five weeks to ensure the grass is at least three inches tall. Mow the grass one to two times, then dethatch or rake it to remove the excess straw mulch. The remaining straw naturally decomposes into the soil.
What happens if you leave straw on top of grass?
If allowed to dry out completely, grass seed or newly sprouted plants will die. Leave the straw on top of the grass seeds until they grow tall enough to be mowed. Leave the straw in place until the next time you mow the lawn, or remove it after mowing the grass.
When can I start mowing straw?
As soon as the grass is about 2 inches tall it is ready to be mowed. As you mow, the straw will be cut into small pieces by the mower and will fall back into the grass where it will decompose and add nutrients to the soil.
