    We installed a new lawn a while ago. Did everything proper, removed old dead grass, tilled, added top soil, seed, starter fert, watered. Lawn looks great last few weeks. Has been cut 4 or 5 times. About a week and a half after applying scotts turf builder fert, now there is several yellowing spots in the lawn. I dont think over-fertilizing did it, and it has been watered plenty. Any indications of what this might be? Lawn is mostly weed free, and no grubs were noticed when installing lawn.

    Is there any rhyme or reason to the spots???? Could it be overwatering???

    spots are sporatic. not overwatering, just a little each evening.

    Possibly a fungus. You're extending the lawns natural wet period by watering in the evening. Better to water early AM before dew burns off.

    Don't water the turf in the evening. It promotes fungus with humid temperatures.

    Don't renovate a lawn in the middle of the summer. Root system too shallow, root system will dry out and plant will die. You'll probally lose from 50 to 80% of the new turf by fall.

    Stop watering in the evening. Apply a fungicide to stop it from spreading. Rake and spot seed.

    Most likely a fungi. Im just south of you here. Red Thread has been a real problem. Ive been growing it out w/ nitrogen but the spots are still visable. I have residentials that havent even kicked the irrigation on yet this year. You may consider stopping the water program all together on that site for a while.
