Heretical I know. Now Im not talking about all my accounts. But my four oldest accounts, all organic at least three years, look much much better than their neighbors or my newer accounts. Much better. Growth is much more vigorous and the green is suprising even to me. These are all lawns that get a lot of leaf mulch this time of year, more so than my other accounts. In any case Im thinking of foregoing a fert app for them this fall. All the po's are tickled to death and I'd love to tell them that the years of going organic are starting to pay off, just pass that fert savings on to them. Its a hit in the wallet though. I haven't read anything about fert apps breaking down leaf mulch more quickly but that's my only concern.
