I reclaimed an old garden I had that had been over run by weeds, wild roses etc. We have nothing but rocks around here and I wanted a bigger garden so I used the back hoe and dug up a 20-25 or so garden. Things in some parts are doing ok but where I planted my first beans was the old garden and they are pale plants that look like they will die without ever having beans. they have flowers that never opened. I planted a new crop 3 weeks after this batch and they look fine. Same variety and 6 feet away.any idea what is up?
