Alright, you all are gonna think Im on crack, but when I was young, my grandmother had one the best gardens I have ever seen. Everything was like it was on steroids. Her secret? I kid you not. She would have me go down to the lake and catch a stringer full of carp, bring them back and bury them in the garden. She told me when they start to decompose, they release plenty of nutrients into the soil. By lookin at her garden, it was hard to argue. Since they are considered a rough fish here in Minnesota, and Im sure in most other states, it was illegal to return them to the water so in the soil they went.
