Some of you might have seen me in my front yard today with a big bag of chicken crumble and were wondering why I was spreading chicken feed on my lawn. Well we are getting to the time of year when soil temperatures are right for switching from chemical fertilizers to organic fertilizers. An organic fertilizer is a product that you add to your lawn for good fungus and microbes to break down to add nutrients to your lawn. In this case I used chicken crumble which is not advertised as an organic fertilizer but makes a great inexpensive one.I got a 50lb bag for $15 from Tractor Supply in Helotes for example.
