About 3-4 weeks ago I planted grass seed in an area of my yard that was previously bare where I now added fresh dirt and soil. The area is about 200 sq ft. There is now a decent amount of new grass growing, but there is also massive weed growth in the area.
How can I get rid of the weeds as I'm afraid they will outcompete the grass? I'm afraid of using a chemical weed killer as it might kill off all the new grass seedlings.
