Sweet potatoes also grow a really cool vine
in water.

You totally lost me on this one. How does one grow sweetpotato in
water? Will they develop sweetpotatos in their roots in water?

I would love to try it. How do I start from a sweetpotato? I'm sorry
to be the total novice here.

Thanks.

I used to have a sweet potato vine many, many years ago. It doesn't produce
sweet potatoes but the vine is beautiful. I remember putting tooth pics in it
and suspending it from a blue mason jar so only part of it was in the water.
Someone told me awhile back that you can't use the store bought sweet potatoes
anymore because of a process that is done to them before they reach the store
and they can't grow anymore. Can't remember what the process was called.
Anyone know if this is true or not?
