I’ve had seed from a couple of different sources and not had success germinating them. I soaked the last batch in water overnight before planting and had the two sprout, which is an improvement on previous attempts! I think they might need a lot more water to sprout successfully, I am going to try a bit longer soak and watering more often. I don’t think all the warnings about not watering beans after planting to prevent the seeds rotting in the soil apply when you have very free draining soil.
