Lemongrass
 

I have been growing Lemongrass for about 15 years.
I have always grown it in pots, bringing them inside for the winter. The
plants have always thrived, and required that they be split at least once a
year.

3 years ago I moved to Northern Wisconsin, and have not been able to get my
plants winter over when they are moved inside . They just dry up and die.

Any suggestions?
