Can I assume that you've never grown asparagus? ;-)

Are you considering this merely a temperary situation until you can locate them in a bed? And how many plants are you talking about?

You are correct, I have never grown asparagus but my in-laws do and they are moving and we are getting the plants. The container would be temperary (maybe a year) until we can settle into a home and establish a proper bed.
