Thanks to all who replied!
I should have known about the soil thing, I can remember how my dad used to 'rotate' our crops on our 40 acres when I was a kid. Makes sense.
I'm going to try a technique I found on a youtube vid, making my own 'potatoe sacks' from garden fabric, and I figure the 3 pieces per sack rule would be right *from what I saw on the vids*. I also plan on putting the sacks in a section of 'flower bed' that my husband hates because he has to 'weed eat' it all the time. It's right next to little 'garage-turned-apartment' out back, and he doesn't want the area too wet for fear of damage to the old structure. It was originally a 'carriage house' back when the place was built....no real foundation, just the concrete slab that they laid down years ago! Now I can put the 'sacks' in that space and the fabric loaded with soil/crops will kill the grass/weeds that want to sprout there. *we actually had grass growing up through the floor of the bathroom!*. When he gets the chance, we're going to pour cement on that side of the building.
Now I just have to commandeer my daughter and her truck to take me to the County Yard to get some of the free compost! *hubby doesn't want to start our own compost pile*
Again, thanks all...looking forward to trying all this new info out. All it should cost me is the price of the 'fabric' and time! *plus it satisfies my sewing addiction to make my own sacks!* heh.
