I would think Throw & Grow would work fine. If it were me, I would get a soil sample just to make sure your work will not be for nothing. If the soil is really acidic, your crops might not grow. Another issue to consider is the size. If the plot is very small and there are animals that frequent that area, they'll probably have it mowed down to the ground before it even gets a chance to take off.

I've never been serious about using throw and grow but I wish I would have. I planted about a 1/4 acre of Hot Spot and it grew okay. The Buck Wheat is what really took off but the deer didn't seem to care for it. I had a bag of T&G that I was going to throw away because it was old and had be open for a while. I took a handful of it and threw in on the plot in one corner when I planted the Hot Spot. The Brassicas really took off and looked great in that one little spot I threw the T&G. I should have planted the whole plot with that stuff. Lesson learned.
