K-lite

[papheteer]

I bought k-lite back in 2012 and ground it up to a powder right after I received it. I have not used it in at least 5 years and I am thinking of giving it another try. Checked it and it’s completely dry. Is it still ok to use? Do fertilizers expire at some point? Thanks!

As long sa it stays dry it should be ok. But I'm no chemist...

Should be just fine.
