Establishing Your New Sod Lawn

A. WATERING

First week – Every day for 15 minutes (mist zones) to 45 minutes (rotary zones) per day for zones in full sun or on slopes, 10 minutes (mist zones) to 30 minutes (rotary zones) for zones in shade half the day or more.

After first week – should now be changed to 20 minutes (mist) to 45 minutes (rotary) per zone every two days (summer), every four days (spring and fall). For low-lying zones that tend to stay wet and zones that are shady most of the day, watering time should not exceed 30 minutes, and preferably these problem-area zones should be shut off and turned on manually only when necessary. WATERING EVERY DAY, REGARDLESS OF TEMPERATURE, CAN LEAD TO DISEASE PROBLEMS AND DROWNING OF ROOTS. If your lawn seems to be drying out in the heat of the summer, increase the time per zone rather than the number of days per week that the system goes on. Lawns will tend to turn light brown in spots during times of drought, but will green up again after the next heavy rain. Watering schedules should be adjusted to accommodate for natural rainfall.

BEST TIME TO WATER – between 1 a.m. and 10 a.m.

WORST TIME TO WATER – between 4 p.m. and 1a.m. ( Fungus will develop and grow when the grass stays wet for more than 6 or 7 hours during the course of the night, so avoid the urge to water your lawn in the early evening.)

B. MOWING

First mowing – 7-10 DAYS AFTER LAYING. TIMING IS CRITICAL. If the sod gets too long it will fall over and mat down, leading to the development of disease. The lawn should not be watered 24 hours prior to first mowing so the mower tires and worker’s feet don’t make ruts in the soft, wet sod. Make sure that you turn your clock off the night before the grass is scheduled to be cut. The mowers should cut off no more than the top 1″ of the grass blades so that the grass does not go into shock. Resume watering after mowing.

Second mowing – Ideally, 4 to 5 days after the first mowing. Follow the same instructions as for the first mowing. (Practically, it will be difficult to get your maintenance company to break their weekly schedule.) After this, a regular mowing schedule can be established.
