I need your opinion. I live in the northeast and had my lawn reseeded a few days ago. They first thatched and raked out the dead grass from winter. They then dropped starter, seeds and finally top soil around the lawn. I’ve never reseeded so not sure what it’s supposed to look like and noticed the soil they used had a lot of stones and tiny rocks. My question is: does this look normal for a reseeding job or did I get ripped off? How long will it take to see some new green grass and results? Should I be doing anything other than watering?
