Last fall I seeded several lawns and it took longer than usual for the seed to germinate (dry conditions). After about three weeks the existing grass really became overgrown. I held off mowing until the new grass became about 3" high. The reason I held off on mowing was because I thought it would not be good to disturb the seed. Some customers complained about how shaggy their lawns looked, but I still held off on the mowing. Would you guys have held off on the mowing or would you have gone ahead and mowed before the new grass started coming in? I appreciate your comments.
