I live in Charlotte and had a great Tall Fescue lawn until last year when it was decimated by the drought and intense heat. This past April I had an irrigation well installed. In late April I over seeded with Fescue. I knew that it would probably not survive the August heat but figured that by late August I would do a fall renovation. The fall renovation began right after Labor Day. At Lescos recommendation I bought a Fescue / KGB blend. The lawn was aerated and the seed was put down with a slit seeder at the rate recommended for over seeding. We put down a starter fertilizer (also Lesco) and then began a 3 times/day light watering to keep the soil moist. The growth was minimal with some areas showing no new growth. After 3-4 weeks I called Lesco and they suggested putting down more seed with a broadcast spreader so we did. In the bare areas we used a rake to make sure the seed had good soil to seed contact and then continued the watering schedule. Lesco told us not to put down additional starter fertilizer. I still have very mixed results. Some areas show the first stages of germination (nothing over ¼) but other areas show nothing. Ive never had a problem growing grass before. Ironically, some of my best results were one year when I just aerated and then put a ton of seed down with a broadcast spreader and didnt water that much (before I had an irrigation system installed). In that instance I didnt see any results until Spring when I had an incredible stand of a healthy thick lawn. But I truly thought that starting so early in the fall this year that I would see some significant results by now. The weather here has been warm except for a brief cold spell with nights getting to mid 30s. We should have high 60s for another few weeks but Im thinking that the grass is beginning to go dormant and that I wont see any more results now. Should I just put down a fertilizer for the winter and hope for the best? And what fertilizer should I use (test results show medium levels of nitrogen, low phosphate and high potassium)? Any help would be greatly appreciated.
