Dry bean questions...
I've never grown any dry beans, although I eat quite a few of them it really makes sense that I should. Plus I like to save seeds when I can and it seems pretty easy.
1) How much beans will a moderately sized bush produce? A cup? A pint? A quart?
2) How much beans will an individual, healthy 8-foot pole variety produce?
3) Will they cross pollinate without physical or distance separation between varieties? I've read they self-pollinate even before opening, but I also read people have problems with crossing.
4) How far would you space a 20-inch bush variety within a row, and how far apart should the rows be?
I know all this is variable, but I'm just looking for ballpark figures to get started.
