Even in a cold climate, perhaps *especially* in a cold climate (I am approx USDA zone 3-4), I find it kind of worthwhile to soak EARLY beans and peas, so they can get going sooner in marginally-too-cold soil. I suppose with something like bush beans that will poop out before the end of the season maybe it doesn't matter when you start them, but with peas it is a real struggle here to start them early enough to get a crop before summer heatwaves set in, and for longer-season indeterminate beans the earlier you get them in the more crop you get out of them.
