Initial Watering: As the sod is installed, water all areas until completely saturated like a wet sponge. The initial watering is the most crucial. Proper watering will soak the sod to the point that the soil beneath becomes muddy. Most problems with new sod are due to insufficient watering. Following initial watering, sod must remain in a wet condition for 10-14 days.
Following Weeks: Continue watering as necessary to keep sod in a healthy condition. At this point, you want to lengthen the time between watering to establish deeper root growth. Keep an eye out for edges, small areas and strips along the driveway that are in danger of drying out. Your lawn is still establishing itself so give it lots of attention.
