I seeded new lawn about 10 days ago. I used heat tolerant Kentucky Blue grass mix on about 20% of the lawn, the rest of it got Tall Fescue mix. I seeded with the rate a little higher than recommended on the package. The lawn have been tilled, pH tested about 7, fertilized. Most of the newly seeded yard was covered by thin layer of peat moss. I kept watering regularly. Now I have about 3/4 inch high grass, but it seems kind of thin (at least to me). There are couple spots that were washed off by sprinklers. Some say it will fill itself in. Should I worry about it now? Should I apply more seed now or wait? I am in Eastern Washington.
