Well, was out starting my first rounds using another pre-m for the 1st time in 13 yrs. I use a z-spray, and used dim 18-0-6, at 15.33 a bag. Lesco 19-0-16, 17.88 bag. yes, granular size is different, but overall coverage I am getting is better than using the Lesco Dim in years past. I actually got off and measured, and I am getting better coverage than years past with the new pre-m using. I am using lesco fert for my other rounds on certain "test" properties and the competitors product on others to see if there is a difference. I know we can all find a ***** about this one. damn times are tough!!
