We accidentally used the Garden Safe DE (not the Food Safe DE) on our garden. Specifically, we used it on basil, squash leaves, and beans. Can we still eat the vegetables of these plants and the basil leaves, if we wash it thoroughly? or are we better off just writing them off this season? We did not get any (as far as we know) on the actual vegetables. Also, does the DE wash off after a while? Thank you!
NO! Do not consume the produce that is contaminated with non food safe Diatomaceous Earth.
