Last year I used liquid fert and granular fert. The liquid scared me a little because we had some very dry weather in the spring and some of my lawns burned. I was using 28-0-0. So I switched to granular and had great luck. I think I'll do liquid on my 2nd applications and granular on 3rd and 4th applications. Liquid is more price effective than granular. What are you putting down?
