By planting in the fall the grass has a chance to set deep roots over the winter before summer heat bakes it. After planting you water every morning, keep soil moist,best is slow and deep, till about an inch high, then about every other day for a few weeks then as needed. That constant watering leads to shallow roots and vigorous growth and the water is in the top level of the soil but over winter the roots grow deeper. In the spring you water the same way, but when summer comes the heat dries up that top layer of water so you water more but it doesn’t really sink down, the grass is growing vigorous and sucks up all the water it can get. You need to water slow like with a soaker hose so water goes deep. Use a slow acting root stimulating fertilizer when s
