Wonder if the cool weather will rot my beans?
I planted a bed of Fortex beans about a week ago, and since then one bean has shown its head above-ground. We've been having pretty cool weather the last two nights though daytime temps have been in the high 60s-high 80s. The lows for the last two nights have been low 40s-50s.
I suspect these temps are right on the cusp of what beans can tolerate and still germinate. Most sites say that daytime soil temperatures need to be 65 for beans to germinate, and mine have ranged between the 60s and 70s. Night-time soil temps are still in the mid- to high-50s.
I don't know what difference it will make, but Southern Exposure notes this: DARK- AND LIGHT-SEEDED BEANS: Dark-seeded beans are more resistant to rotting in cool soil than light- seeded beans. Beans need a minimum soil temperature of 65oF (18oC) to germinate well, otherwise rotting may occur.
Fortex beans are pretty dark, so I'm hoping that gives them a bit of extra protection against the cold. I guess we'll see.
