I did, twice. First time it was in a 12" nursery type of pot, and it didn't do that well. Second time it was in a 14" pot that was quite deep (about 2 1/2 feet), and it did a bit better, but I still wasn't happy with it. I think it had more to do with the drier and hotter soil conditions in a pot than the lack of leg room.

I'm going to try it again this year in a pot that's placed in shade and I'm going to keep the saucer full of water so that the soil doesn't dry out.

I am trying some this year - planted them in small pots but they are not looking so hot, and growing really slowly. I think maybe they need a lot of heat??

I planted some seed last year in June, in a LARGE clay pot (14", I think), with quite a bit of sun. I began by training the vines up a support and they took off from there. I just loved the leaves, flowers and beans. I tried to eat the beans but didn't like them - they were bitter and tough (maybe due to poor watering). The vines were worth it just for the show they put on. I saved the seeds but I'm not sure how viable they are. Good luck.

This plant requires a large container if you wish to plant them in containers. They do better in huge planters.

Why.. well the roots like to go deep, small container tend to have limited amounts of nutrients and there's and also are prone to drying out faster. All would just add 'stress' to the plant which stunts it's growth.

I realize this thread is a bit dated now but I'll give it a shot. This plant does ok then in a 14' planter? Okay in plastic? That's what I'm thinking of buying. Two really fat plastic planters placed on either side of my arbor and then the vines. Also wondering what kind of soil. Potting soil? Not sure what these guys might prefer.

Thanks.
