Customer called me and asked me about a fert program (for which I just started) and dethatching. I went by for an estimate, and really think the dethatching will be useless. Seems he has alot of moss, a myriad of pine trees surround his property. Should I instead sell him on a heavy liming, then maybe an aeration and overseeding. How many pounds of lime per thousand...my guess is that his soil is just having a high PH. Any advice, or just go ahead and dethatch?
