Product Q&A

Answer:

The Phos-Chek Long Term Fire Retardant  product label states that it will last "for the entire fire season so long as the weather remains dry.  Rainfall of 1/4 in. or more will wash Phos-Chek off treated vegetation."  If grass is cut or if you receive more than 1/4 in. of rainfall, you would need to reapply.
