I have read that the germination rate for Dwarf Bean seeds can only be about 75%. So to increase the rate I chit my seeds between two damp sheets of kitchen paper and then pot up into 3" pots. Out of 30 seeds chitted 29 produced roots and carried on to the planting out stage and produced a good crop.
