Overseeded lawn

Andrea Ribeiro asked 4 years ago
We had a new (less than 1 year) very patchy lawn which I overseeded over 2 weeks ago. I prepared diligently the existing lawn (aereted, de-thatched etc). I cut the grass fairly tight, laid top-soil then seed down. Gently raked the new seed in. Watered every day, when it wasn’t raining. I am still waiting for germination! The problem now is that the existing grass it getting quite long and I can’t cut it. Do I just wait it out and hope the new seed eventually germinates?
