I just bought a house and repaired the sprinkler system. The owner previously was using well and it was turning the house walls rusty orange. There is an area that I thought wasn't getting enough water but now I'm not so sure. I live in South Florida so it's been rainy plus sprinklers 4x/week. The grass is dry near the corner of the lot and weeds are taking over in those areas. I tried tilling and spreading some seed and some new grass has sprouted in those areas. Do I assume it's just dry grass or is it a fungal/pest issue? I have no idea what I'm doing. Please let me know the best route to take here. Thanks
