I had a customer ask me to aerate/lime/fert. & over-seed. The back of his lawn was in pretty good shape. The front lawn was almost 100% crabgrass and lespedeza. I sprayed out the crabgrass and lespedeza 2wks. before my work, above. Rookie mistake = I seeded the front at the rate of a typical over-seed (4-5#/MSF). I now think I should have seeded this portion of the lawn @ a much higher rate. Agree? The back lawn looks great. The front......not so much. Now my Q.....how much (if it's possible) is too much seed (for an over-seed)? I'm planning on going back over there tomorrow or Friday and scarifying (he did get some wash-out, during a storm) the trouble areas.....and putting down more seed. I did set expectations at what I thought was a "reasonable" level. I told him his lawn didn't get in the shape it was in overnight. It wasn't going to get in the shape he wants it in in one app.. But, I think it should be "better". He does have irrigation. He's kept it moist 2X/day, since I seeded. Thanks, in advance, for you input.
