It never ends. As old products go off market, I need to learn how to use the new ones or end up looking stupid. My customers are extremely conservative, even regressive, so selling new and modern to them gets bad if it does not totally work.
Much of the technology that I use is actually old school. It is what produces the best results for me. While everyone is a buzz about one application granules, I use liquids on a regular application basis. Very 1960s or 1970s. By now, you know about the soil conditions I deal with. No fast or cheap answer for it unless someone comes up with a product that totally removes all alkalinity from the soil in one shot without killing the existing lawn and landscape.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
Benjamin Franklin 1775
Sell not virtue to purchase wealth, nor Liberty to purchase power.
