What is the best method to seed over an existing lawn?

Question

The lawn was filled with weeds and crabgrass, by the time they all died out after spraying I am left with very little actual grass. Can I use a thatcher and then just spread seed over this fall

Answer 1

Don't use a thatcher. Thatch is not your issue. Soil compaction is. Rent an aerator and run that over the lawn. Then go back and rent an overseeding machine which cuts little grooves into the soil and seeds at the same time. Water, water, water.

Answer 2

grass seed and put hay over it

Answer 3

Our grass was the same way. I bought grass seed covered all the grass and watered twice a day you have new grass growing in about two weeks. The key is watering twice a day!!!
