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.

Corn gluten meal will work just fine when applied to turf. It does not matter what form it is in, the granulated forms are easy to spread with a slinger but there is no difference in effectivness. Timeing is the most important thing. Spring applications should be done early, about the time daffodils are blooming. It works best if it is well watered in, then the ground allowed to dry out. Following up with a fall application helps. Keep in mind this is a long ternm type of thing and is most effective after a few years.

In my 2-year trial experience, I found it is not a particularly good fertilizer and it is not effective in suppressing weeds. In that 2 year period I saw no effect on germination or growth. Beginning in early spring, I kept a layer of it in sidewalk cracks, between pavers, and in a small vegetable garden. A layer of bright yellow meal was always visible, all spring, summer and fall. The weeds grew very well thru it. I suppose the elevator could have sold me something besides corn gluten meal, but I don't know why they would.

The GCM I buy says on the bag "do not apply to newly sown grass until it ahs been mowed twice." So, I would not apply the stuff to newly seeded areas until you've had enough growth out of the seedlings to need to mow them twice. No cheating and mowing when they don't need it!
