Potassium to kill Spanish Moss

Question

After reading how to kill Spanish Moss on your site, I went & purchased Muriate of Potash, as I had asked for Potassium. I have grade 0-0-62, soluble potash (K2O)62.0%. I sprayed a good mixture mixed with water & did a test spray. Three days later, I see no evidence of browning or of killing this moss. Did I do something wrong, is my Potash not correct?

Please advise me.

Thanks,

Muriate of Potash is also known as potassium chloride. The potassium you want to use is "potassium salts of fatty acids," which is available in liquid form in several brands, such as "Safer Brand" for moss and algae.
