Can anyone tell me if I can plant the root end of the horseradish I used for my Passover seder and get a horseradish for next Passover? I live in New York City (zone 7), with a small yard in front with northern exposure, and a sunny strip in the back with southern exposure. If it could be done in a pot, I have a back porch (easier to access than the strip in the back which is downstairs, out the basement), which is very sunny.
If this can be done, can anyone tell me how? Thanks.
