At least check the analysis for chlorine percentage before doing anything further. potassium nitrate is available in liquid soluble form and is product of choice for centipede.

What is an acceptable chlorine %. My town only sells sur gro I think with 12% chlorine if I'm not mistaken. Not sure on the source. Also was thinking of using 16 4 8 for a slower release.
