Debs from the Key West Wine & Gardening Blog 
mentioned growing stick beans in pots.  
Something that sounded difficult.  
She has kindly explained her methods here:
I just fill 12″ or 14″ sized pots with soil.  
I put -5 beans spaced evenly apart.  
Within a few days the sprouts will pop up and
then you will be amazed how fast they grow.  
Once I see where they have prouted, 
I add my stakes which are about 7 feet tall to the pot.
The beans ind their own way to the stakes, which is really cool.  
Up they climb, blossom and bean.  
I do feed them every 2 weeks.  They are so fun to grow!
Thanks, Debs, growing stick beans in pots looks exciting!
