Kerai,
Look up a local Feed store. Just do a search on Animal Feeds in your zip code online.
The feed stores carry Corn gluten meal, if you want to buy it in a 50 lb bag.
If not, try a locally owned nursery, not a big box store.
They will either have it, or know where you can buy it.
I get my Alfalfa at Tractor Supply.
It wouldn't hurt to see if they have it, some horse foods
are made of corn gluten meal and molasses, which is also good for your gardens and lawns.

I'm in NC, but will share my experience with finding CGM. I've been using it for about 5 years.

The local nurseries do carry it, but I've found I can order it from a local hardware store (family owned place) for a whole lot less. The same bag would be over $40 at a nursery, under $30 at the hardware store, so it pays to shop around. The hardware store doesn't keep it in stock, but they order it for me. I use Espoma brand, but am pretty sure Safer makes it too (I know I used them when I was new to CGM).

I would love to get it at a local feed store and spend less, but when I first researched CGM, I read the quality isn't the same and it may not have the same effectiveness. You might want to research that yourself, but here's a link that has some info: http://www.gardensalive.com/article.asp?ai=753 . I realize it's from a company that wants to sell you their product, but I did see similar claims in other articles as well.

Thank you both for your inputs. I will try to call around this weekend and buy it. I am excited even to think of the possibility of not having to weed as much (of course, not polluting as well).

Appreciate your help,
Viji

Just wondering Kerai if you found a local source for the CGM? I live near Columbia also and have looked for it for about 2 years now. Tks.
