Watering Tips

When we set up your clock for new sod we usually run the irrigation system 3 times a day. The amount of time depends on the season. In the middle of the summer when temperatures are in the 90’s, new sod needs more water than it would in May or October. The clock should be changed as the weather or sod matures, going from three times a day to two, then form two to once. When the sod is rooted you can run the system every other day. Set the station run times to the weather conditions.

When you are growing new grass, the soil and seed need to be kept wet. When you have newly seeded grass instead of sod, the times still should be three times a day but shorter station run times.

If you had your irrigation system put in an established lawn we will seed the lines put in by the pipe puller. In order to get the seed to grow, the grass should be kept wet.

There is also such a thing as too much water. Newly planted trees and shrubs need water, but the roots also need air. When you over water, the roots sit in water and do not receive the air that they desperately need. The roots will rot when they sit in water. This is one of the main reasons new plantings die.

When your new lawn is established, you will still have to change the station run times for the seasons. Remember, the amount of water needed in the middle of summer is a lot greater than in May or October. If you need help with this, please call.
