last yr, i had my EE growing in a bucket, and when the frost came, i just dried it out some, wrapped it loosely in newspaper and stored it in my basement..
This year, i planted the darned thing in the ground.... im not taking it out, it will be leaving a crater too close to the edge of my pond..
I do have an offshoot, that is in a clay pot, which ill bring inside, if i remember.... LOL
