Last fall one of my customers who happens to live in the an area with alot of mature pine trees, and sandy soil, not to mention a vastly shaded area inquired about how I could thicken her lawn. I asked my friendly Lesco rep what to do, and he came to the lawn and promptly recommended a core aeration, along with some overseeding. I sold the woman on this,(she didn't check with her crabby a** husand). Long story short, he was irate this spring. Any thoughts on right or wrong. I honestly thought I was doing the right thing. In fact I probably did not charge nearly enough for my services throughout the year, and I pride myself and my business on going the extra mile. Lets hear it. I thought the lawn was pretty good given the conditions.
