I'm growing blue lake bush green beans from seeds. They're sprouting and growing like crazy. About 3 inches tall already. I didn't expect them to grow. My quesion is what is the smallest spacing I should leave between seedlings in a row? I just threw the seeds in rows at random spacing so they're pretty close together right now so I want to pull some to create more space and then transplant them to an area where no beans sprouted. The rows themselves are spaced over a foot apart, just close along the row. Thanks
