Give your new lawn at least 2 to 3 cm (1 inch) of water within 30 minutes of installation. Water daily, or more frequently, to keep the turf moist until it is firmly rooted (about 2 weeks). Afterward, switch to less frequent, deeper watering.
Weather conditions will dictate the amount and frequency of watering. Ensure your new lawn has enough moisture to survive hot, dry, or windy periods. Water areas near buildings more often, as reflected heat can dry out the turf.
Caution:
During the first three weeks, avoid heavy or concentrated use of your new lawn. This gives the roots time to establish firmly in the soil and helps ensure the turf remains smooth.
