Er… umm… I have 2+ yards stored in my garage because it burns everything I tried it on except a medium sized landscaping tree.
I think a labratory test is what I need, because I’d like to use it. The plan had been to make my soil mix with peat, perlite & that, but it’s “toxic”.
Even as a thin top-dressing it causes foliage to go pale on anything so far.
