Hello all, First and foremost, I searched around for an answer to this before posting, but couldn't seem to find my answer. I live in Southern New Jersey (near Philadelphia) and slit seeded my lawn on September 30th. My seedlings are germinating nicely, but my existing grass is becoming quite tall. At what point (what height) is it safe to cut the grass considering the youth of the seedlings. BTW I seeded with fescue. Any input is greatly appreciated.
