Does lime go bad? #230448

Asked March 11, 2015, 10:43 AM EDT

Bags of lime have been sitting outside in the weather for two years and have turned dark grey. Is it safe to use? Is it still beneficial?

Polk County Oregon

Expert Response

The question does not have a sure answer, but we can say that unless this material has been soaked in something other than water, or unless something (bacteria, mold) is growing in it, it does not pose any risk - not toxic. In fact the best way to dispose of any agricultural/horticultural product is according to the label instructions.

It's likely less beneficial than it would have been if it had been properly stored. In your shoes, I'd apply this at the label rate.
