Did you know that healthy grass is 70% to 85% water? To maintain active growth your turf will need .75″ to 1.5″of water a week. Too much water and soil may get saturated to the point that roots may not get enough oxygen to grow deeper. Not enough water – especially during the summer months – and everything dries out, causing the grass to brown and go dormant or maybe even die.
Watering in the morning is usually the best option. Watering during the day leads to more loss from evaporation. Watering in the evening or at night leaves the grass wet too long and could encourage turf diseases. Water between 4:30 am and 8:30 am when the wind is calm and the air is cool for best results.
Generally speaking, an inch of water will moisten clay soils 4 to 5 inches deep. One inch of water (.5″-1″ once or twice a week) in the cooler months is plenty. 1.5 inches of water (.5″-.75″ 2-3 times a week) in the summer months is better. Make adjustments for rain or unusually hot weather as needed.
