I love your black pinto bean. I am curious as I know beans in general require sunlight to grow but I saw your pinto bean is growing inside? I am myself trying to grow some drawf beans and it is a success so far. I grow them in pot as well. At first, I only expected to see their purple flowers but then I have some fruits. Not much sun in my garden so I am happy with it.

Oh thanks for your tip on mixing egg shells with lime juice. I will try it for my beans as well.
