I seeded my lawn about 14000sf three weeks ago we got a severe thunderstorm
two days later washing out much of it. I continued to water to see what
would happen. Now I have a lawn that is very maze like patterened and
blotchy about 40% grass but very nice where it came up dense.

What I am wondering is can I use a Slit Seeder to overseed/reseed the lawn
without doing alot of damage to the good grass that has come in.

Thanks
