Take a lesson from the professionals. Hide it by pretending it covers new improvments and features, like when cable TV adds new channels you never watch in foreign languages. (add a tiny bit of iron...or zinc.) Or like potato chips; bigger bag same price. ( less fert--cheaper nitrogen source.) So much the better if you have actually improved your program--better fert, better herbicide, wetting agent, partial organic ingredient, better guarantee, you took an educational course and learned more about grass fertility. Better equipment. Upgraded your computer and software. more...any suggestions?
