Winterize irrigation systems

October first is the traditional beginning of the season when irrigation systems are winterized.  It is an important profit center for many landscape contractors.  Several contractors have told me they make $1,000/ day winterizing irrigation systems.  I do it as a service to my customers and a few others.  I limit my list to 100 customers.  I can do all of these in a long week or a couple of easy weeks.  I own my compressor with gives me the flexibility to work with customers and the weather.    I monitor soil temperature each week and use this along with monitoring long term low temperatures forecasts.   Although grass tops stop growing about the 2nd or 3rd week in October, roots continue to grow until soil temperatures drop to below 40 degrees F.  If irrigation systems are turned off before the roots naturally stop growing it puts the plants into water stress.   Plants that go into winter under stress do not come out of dormancy in the spring with as much vigor as those who go dormant in a hydrated condition. 

soil temperatures so far this season are as follows:

October  2nd  55 degree
October  9th   55 degree

Enjoy the winter, I will
