I am in my third year of running my one-woman, one-acre market

I don't know of a readily available and affordable seed starting
soil mix that is certifiably organic. I have been using Pro-Mix
BX, which has a wetting agent (don't know what it's called) that
discludes it from organic approval.
What are some of the options for organically-approved seedling
mixtures that will stand up to the quality of seedling produced
in Pro-Mix BX? Thank you!

The ATTRA website has a comprehensive section on “Potting
Mixes for Certified Organic Production” http://attra.ncat.org/attra-pub/PDF/potmix.pdf,
which lists several national sources for approved organic potting
soils and includes a host of information about making your own mix
and pertinent issues surrounding different ingredients you might
Here at The Rodale Institute, we produce our own potting soil using
leaf compost, perlite, vermiculite, a small amount of topsoil and
some organic peat. We pasturize the compost to kill off any weed
seeds, screen it and then mix everything together. We seldom have
any trouble with the mix. We've never used any purchased potting
mixes, so I have no personal recommendation from the list they provide.
Hope this information is helpful.
