First 3 Weeks
In our climate it is essential that you keep sod properly watered for the first month. Water the sod 3 to 4 times a day during the first 14 to 21 days depending on heat, sun, and season. The idea is to get the roots to chase the water down deep into the soil. You can lift a corner of the sod to determine the depth of moisture. Make sure you are soaking all the way through. During the first month stay off the lawn so it can take root and so that you do not leave depressions from your footsteps. If the lawn starts to shrink and brown you need to water it more. If watered correctly the roots of your new sod are going to penetrate the soil faster and grow stronger. At the end of week 3, dry up the yard enough so you can mow.
Weeks 4 & 5
This is a transition phase from frequent daily watering to fewer cycles per day. During week 4, reduce waterings to 2 to 3 times per day. By week 5, water 1 to 2 times daily and if the new sod is not drying out skip a day between watering cycles. Water your lawn in the evening or early morning when less evaporation occurs. After week 5 you can now get the grass on a regular watering schedule.
Rest of the Season
The new will need extra water the first growing season and especially the first 6 months. As its roots begin to reach deeper it will start to need less water. If your sod looks dry, it needs watering. The trick to new sod care this time is deep watering less frequently. Again it is to help the sod grow down and develop a deep root system that can survive on less water later. After the first two months it is good to stress your lawn, but just a little. This means let your yard dry out a little bit and once you see signs of stress appear, go and water. This is so you can fine tune sprinklers. Adjust heads for proper coverage, change nozzles for more or less water in target areas, and water in early mornings.
