The fall of 2015 has been a very unusually dry and warm one across the midwest. With high temperatures in the 60’s -70’s and lows in the 50’s, the conditions are just right for some last minute fall lawn seeding or repair with sod.
Many irrigation companies are also wanting customers to winterize their lawn irrigation systems this time of year. However, with very little frost, the conditions are right to continue watering the lawn at least a couple of times a week.
The rule that I have found reading several articles on this topic and having looked at this topic of when to stop watering in a past article is looking at the soil temperature map. Once the soil temperatures approach the 40 degree fahrenheit mark, this is the time I start looking at winterizing and stopping the flow of water to the outside lawn irrigation system.
Watch the weather and be prepared when temperatures drop this fall. For the next 10 days, it appears the temperatures are not even close to dropping toward 32 degrees fahrenheit.
