I have a theory that if the above-ground Jimson Weed growth was kept trimmed away, then the tomatoes would not be toxic. But I don't have a lab to test my results, so I didn't try it.
The Jimson Weed patch in the cow field behind my house is an 8' tall jungle. The roots over-winter, which is why it comes back so ferociously. I think an established patch of ground with a Jimson Weed root system in place would grow the biggest tomato plants I have ever seen.
