Natural Science Forum / Biology / Botany / April 2004pesticide free potting soil
Dear Plant-ed folks: I have some colleagues in chemistry that want to grow some carrots and potatoes in a pesticide free environment. Do you know if there are any potting soils that are pesticide free? I thought of mixing up our own from vermiculite, perlite and peat moss but then there's question about the exposure of the peat moss to pesticide. They can test the soil themselves, but it would save some time and effort if pesticide free potting soil is available. Thanks!

Would that work? I'd consider even "organic" potting soils possibly contaminated with pesticides. What's the purpose of the exercise? > Dear Plant-ed folks: > [quoted text clipped - 22 lines] > > --- |
