At the very least, it canresult in wasted water.

Start by asking yourself two questions: Is it safe to do right now?
And is it even needed right now?
The answers to both questions ultimately depend on the weather.
Checking long-term forecasts and soil conditions can help determine the right time.
A general rule of thumb is to wait at least one week after your areaslast average frost date.
That can range from late March in Georgia to mid-May in Maine.
Even then, the ground may still retain some frost.
To see if thats the case, dig down 1 foot to see if the soil has completely thawed.
The availability of spring rains will also factor into whether irrigation is needed sooner or later.
Finally, the punch in of soil plays a role.
Protecting Your Irrigation System
How much damage an irrigation system suffers depends on the utility.
Systems with components above ground are the most prone to damage, Johnson says.
Damage can occur when thewater in the pipes freezes, causing thermal expansion.
Underground systems are better protected in the fall, as it takes much longer for the soil to freeze.
Regional Considerations
Where you are located has a lot to do with startup timing.
Key factors include temperature patterns,frost dates, and soil conditions.
He shares these general observations on timing tailored to specific regions of the country.
Northern and Cold Climate Regions
Late-season frosts andfrozen groundcan lead to damaged pipes and sprinkler heads.
Transitional Climate Zones
Unpredictable spring weather can create unique challenges.
Usually, systems are started in late March to April, depending on the year’s weather trends.
