An entrepreneurial reader writes about the worry of pesticides in worm composting:
“I am thinking of starting a system of collecting fruit + veggie scraps from people at my church to upscale my worm composting. (The past year I’ve had two 20-gallon bins– so approximately 4 sq ft– and now I’d like to try a 32 sq ft raised bed w/ roof to keep out rain…. I’m fortunate to live in mild climate _________, so I don’t have to worry much about freezing or many days above 90 degrees.)
My wife asked a good question: if the majority of the fruit + veggie scraps are not “organic,” wouldn’t there be some chemicals in the resulting worm castings? My thoughts on why this shouldn’t be a big concern:
The process of the worms/microbes digesting the scraps helps to “clean” the scraps. (I thought I heard this somewhere, but cannot confirm it.)
The slower process I am trying** allows time to break down any chemicals.
