We moved into our house 4.5 years ago (new). We have always had a part in our front yard that doesn't do well in the summer so this spring we had the soil tested. We found that about an inch under the sod there is compact gravel (like in a parking lot). We think they graded the rocks from the street and driveway and just threw the sod on top of it. So deep watering isn't going to happen. We live in Kansas and have had 2 weeks of 95-105 temps and have at least 2 weeks left. What is the best way to water without killing our water bill? I know the best way with normal soil is to water deeply to encourage deep roots, but if we can't get deep roots at all should we be watering 10 minutes a day everyday?
