Onis Cogburn says that Amano's secret formula is not just bad for us, it's bad for Amano. The only reason I can think of is that I am surely more likely to buy a Tropica fertilizer than an Amano. Just because Tropica has the respect for me to let me know what they are selling. Most people, I think don't really care. Why is the secret formula bad business? Justin in Springlike Savannah
