Do you think plain old corn meal or corn flour (like you use for tortillas) could be used as a substitute? I'm thinking of using this corn gluten method on my vegetable garden, so on bare ground, not on lawn grass. What do you think? Worth a try?

Annie, I honestly do not know, you could always try it in a small area as a test.

The corn meal you buy at the grocery store is not the same product
unless you purchase Whole ground cornmeal
The other stuff lacks the outer shell and is mostly composed of the starchy inside , lacking in the most effective parts.

Personally: I would not waste my time and a whole ''weed season'' on the wrong thing.

Thanks Cinda! I was thinking of doing a little experiment area in the veg, just to see if it had any effect. I think I can get whole ground cornmeal here....

I am not finding it in my area (Atlanta) and I would love to use it. I might have to use the whole corn meal too as a trial. Nothing to lose just a bit more nitrogen for my roses? ☺

I checked at my grocery store today and the corn flour (the tortilla flour) definitely said "GLUTEN FREE" so that's not an option. The corn meal (Indian Head brand) said it was made from the whole kernel, so there's some gluten in it... I'm going to try sprinkling it on a small patch of dirt and see what happens. I'll keep you all posted of the results!

Annie ~ Well, what was the result?

I did not see much difference between no cornmeal and cornmeal, except where it was really thick (like a half inch) and at that point, it might as well have been any sort of mulch.... Anybody else try this? (Plus, the cornmeal color looks not so nice sprinkled all over the place...ants too.)

The corn gluten is a yellow/orange color, when it gets watered in the only sign of it can be a "kegger" smell for a few days. I had no problem with ants or other insects. The corn gluten works very well as a pre-emergent in my yard.

I put mulch on top of mine, as it was rather unattractive. Bright yellow, and then the cat wanted to eat it! I covered it quickly and watered it in.
