I've read about corn meal gluten but haven't tried it. For a weed killer, it needs to be applied before the seeds germinate to keep the seeds from germinating, as you mentioned a pre-emergent. For fertilizing, it needs to be used in combination with other things like molasses and fish emulsion.

I use corn gluten meal and I love it. In the spring I will apply it to the unmulched beds quite heavily and let it sit a week or so after a rain before mulching. Personally, I find it has worked well for me.

MG does not "go bad" per say, but it can create toxic build ups of salt in soil (as well as heavy metals) because of the way it is made. The carrier in chemical fertilizers are salt. This may not be the case at all for you, but it is something to keep in mind.

When we moved here I used miracle gro - and then I had a soil test because things weren't working out so well. Besides needing to ammend the soil well for drainage, I needed to stop the miracle gro! The previous owner had also used it and we had to let it leach from the soil for several years and then I went organic.

My brugs do best with PLENTY of water and alfalfa meal. They are piggies and love a quick shot of nitrogen!

I should have clarified that the stuff in my greenhouse in 3-4 inch pots and gallons are growing as well as i would like. they are growing just not to what i see in the nurseries. I don't use MG in my beds.
so is it too late to try the cornmeal gluten? also, when you say alfafa meal does that include rabbit food which i have a lot of? would that work? i put it around my rose and they love it!!

Ok, this is sort of a lame question, but where do you get corn meal gluten? Don't some people also apply it to their lawns? wig

You can find it at feed stores or farm supply stores that carry feed for livestock.

Corn meal gluten can be purchased at farm supply stores, or on-line. Yes, rabbit pellets can be used to make a tea. Somebody posted a recipe for adding other ingredients and creating a fermented brew for fertilizing. (You could do a search to find that thread, alfalfa tea should bring it up.) I just make straight rabbit pellet tea--let pellets soak overnight in a bucket of water. You could dig pellets in around plants, if you don't have a dog who thinks rabbit pellets are a dandy treat. I tried digging some pellets in and the dogs went around behind me digging them up to eat them.
