All the tutorials that I could find on growing beans have said to find non-irradiated dry beans from a bag:
I even found one article saying that beans can only sprout when they had been dried.
Only dry beans can germinate, so choose from those in the bulk dry bins or those that are bagged.
I'm at a dilemma here because I want to grow Chinese Long Beans, but I can only find them in the fresh state at the supermarket. They only sell common bean varieties in dry bags.
How would I make the beans inside this fresh batch into viable seeds? Or is it not even possible? Some people have said you need to have over-ripened the bean on the stalk and let it dry naturally before plucking them. I wonder if these fresh supermarket ones were picked under-ripe.
