From Organic Gardening Magazine, July/August 2000 Issue. Miracle-Gro is a synthetic fertilizer that contains ammonium phosphate and several other chemicals that can be toxic to your soil and plants. It is prohibited from use in certified-organic farming.
If youâve got to do it, though, Miracle Grow has a new soil called Miracle-Gro Natureâs Care, it come sin a green bagâyou might have seen it. Give that a try. You could always go with the old school Miracle Grow potting soil in the green and blue bag. It has the moisture control. And pick up some Perlite with it too because that soil is thick and heavy. You donât want a tight substrateâthatâs not good for growing weed.
