I wouldn't garden without it
I use this product in my garden every time I plant something. The plants turn out great and perform beautifully. I think my green thumb has a lot to do with this product. It's organic and I don't worry about using around my food. It does have a odor when you are adding it to the soil, but it goes away and you don't smell it afterwards. I'm used to it by now. I swear by it.
