Unless you use effective protection against slugs (which, unfortunately, means pellets as all other methods are only partially effective or worse), insurance by means of multiple redundant spare plants is the way to go. Most decent suppliers put so many seeds in the packet that the average household couldn't possibly consume all of the produce if they were all planted and grew to full production. For one 2 metre row, I sow 15 beans individually in 3" pots in mid April (depends on where you live - I'm in central UK- add or subtract a couple of weeks depending on location and/or weather.) Plant out when 8 inches tall. When planting out, push a bean seed into the soil a few inches away (insurance policy 1.) Take the empty pots and sow another 15 beans ready to replace those which you have planted out and which will inevitably be eaten by the slugs (insurance policy 2.) When you plant these out, push another seed into the ground a few inches away (insurance policy 3.) Most packets have 60 seeds. Now you know why!
