Yep, I get a big bag of it and make salads. Might have to grow some. I’ve grown Kale last few years. But had little bugs on it covering bottoms of leaves with white crap this year. Didn’t use much of it
I was finding harlequin bugs this year, but something else too that was chewing the leaves down to nothing.
In addition to picking them off I was trying lime on them, diatemactious earth and insecticidal soap. Verdict: Not sure if any helped or not.
