I can't tell you where you can find it specifically, but I would start by checking with local animal feed stores. I can also tell you that CGM doesn't work as you have described. It doesn't suck up all the water preventing germination. It prevents root formation via natural chemicals released into the soil. CGM isn't as effective or cheap as many synthetic preemergents like Dimension, but it is non-toxic and completely safe.

Thanks for your correction!

It is also not a weak fertilizer. It is the strongest organic fertilizer I have ever used. Stronger organics would be soybean and then you would have to get into meat products to get more protein on the ground.

Don't waste your time and money on CGM. As a pre-emergence it is poor at best, and many who have used it thinks does nothing at all. As a fertilizer if the strongest of all the grains, but is the most expensive option available.

I would recommend trying CGM. I put it down a month ago and I have zero crab grass and and my lawn really looks great. The CGM is a very good fertilizer too. I had to order it off CSN stores but they are out of it now. You might try "tractor supply", if they are in your area. I live in FL and C-grass is always a problem. I don't see much dollar weed also, which was killing me last year. Good luck.

My sister in law said that she saw CGM in a Southern States store around Laurel/Ellicott City, MD
