Maybe something for Merla's roadside project? Have you tried using corn gluten meal as a pre-emergence? I'm trying it this year in some of the areas that have tough annual weeds that are hard to get into to mow. It's supposed to deter any seed from sprouting, while acting as a fertilizer to existing root systems. I have some tough grassburrs that seem to multiply in my yard the harder I try to dig it out. Since it's a blade, I don't recognize it until it actually forms the seedheads, and by then, it's a large clump. You can use it in the garden in an organic program, BUT, no where you're going to direct seed anything. Ok for use around transplants and crops already up out of the ground, but I don't know how long the effectiveness is, so I don't know what the wait period would be considered safe to plant. Does anyone here use it?
