We have been using JDL fert product for many years with decent success. I feel that the product does not break down properly and get into the soil as it should and lawns are not as green as they could be in my oipinion. We use their basic program with 2 steps of Dimension in the spring and use Speedzone and Q4 mostly for any breakthru. I just feel a finer particle product would serve us better. I am in southern mass so what other dealers and products should we look into for better performance. Any info is greatly appreciated.
