RE: Plot failure -
I know it's a stupid question but did you get a soil sample? I remember the post about the clover and now the extreme isn't growing I think something is up. The extreme is supposed to grow to a ph of 5.4.
If you tink you're going to till it over again I would sample the soil and my personal recomendation would be to try some Imperial Powerplant if you're interested in an annual. The beans like a warm soil so itshouldn't bee too late to get it in the ground. The deer in the northeast really took a likeing to it.
