Mistina, what are you hoping to accomplish with this mixture? What is it supposed to do? The problem with many of these so called 'natural' or organic home remedies is that they really don't do anything despite being touted for all sorts of magical properties. Corn meal - or even corn gluten meal - really doesn't have significant herbicidal or fungicidal properties. Scientific testing to support any consistent herbicidal properties have not been able tosuccessfully duplicate the results generated by Iowa State University that caused all the hoopla to begin with. And the fungicidal properties simply do not exist. But since CGM is nearly pure protein, it's not at all a bad organic fertilizer (if you overlook the consideration that most feeder corn grown in the US is GMO'd). And Epsom salts (magnesium sulfate) provides absolutely NO benefit to the garden unless you have a magnesium deficiency in your soil. If you want to use any of these or similar organic home remedies for weed control or pest or disease suppression, do some research first before you spend money purchasing these products needlessly. There are numerous websites outlining any scientific testing or investigation into the alleged beneficial properties these products may or may not possess. Look in particular for scientific papers or websites with the .edu suffix. Finally, purchasing food grade equivalents of these products at a grocery store will always be more expensive than buying in bulk from a feed lot source.

kathyga........I've written about it a few times here. Basically, the grass - and a couple weeds - in the corn gluten meal containers grew like crazy, telling me that it is an awesome fertilizer and not so great preemergent. I didn't get any crabgrass in that container, but I recall getting a really weird weed that I had never seen before and have never seen since. The most striking thing was the difference between the corn gluten meal and non corn gluten meal containers. When I dumped out the corn gluten meal container, the roots were REALLY deep and thick, causing the whole thing to come out in one giant clump, which was pretty interesting since I didn't spread too many seeds in there originally. The one with no fertilizer was pretty sparse in terms of root action.

Maybe ten years ago (+ or -), Corn Gluten Meal was the next big thing and there were websites touting it as wonderful. Iowa State was a big pusher. Now the websites are gone. I got some CGM from a store somewhere in east TN who told me with a wink and a nod that CGM is what's left from making 'shine. It did have an interesting aroma. And mice love it. I put it on the ground and the weeds came up, With no respect for their having been planted below CGM. From what I read CGM only suppressed seed germination at temps 60ish and above. So winter weeds- home free. Spring weeds home free as well. Summer weeds also did rather well. Maybe as an organic additive? And one of our cats put on good weight by eating the mice that lived in the bag of CGM that was back in our old corn crib.

How much for SBM for you? It's not cheap by me either. I like Milorganite and the fact that it has iron in it. Definitely greens up better for me than SBM.
