ANY plant can be grown in containers, provided you understand and can properly accommodate the cultural requirements of that plant and can supply large enough containers. But asparagus would not be my first choice for a container plant. It produces a BIG root system and dislikes crowding plus you need a bunch of plants to realize any sort of reasonable harvest (5 or more plants per person!!) That's a lot of big containers :-)

This link on how to grow asparagus in containers should be of some help. My primary issue with this proposal - other than the awkwardness/impracticality of the operation - is the short life of container grown plants. Since asparagus starts don't really produce significantly until their 3rd year, you've barely gotten anything going before you need to start over again.

Thanks. Would you recommend raised beds for asparagus instead.....???

I would agree with gardengal...

Raised beds would work, but again, they'd need to big enough to support that root system space needed, and I think you'd also have to consider what was underneath... as in what type of ground the beds would be on in relation to what you fill them with.

If I were going to do that, I'd make sure I chose a permanent spot... and I'd work the earth and improve it a bit before adding the raised portion, and I'd probably fill those beds with the same or similar medium, getting it mixed in a bit. That's how I'd do it in my own environment... I'm in zone 5, IL... but everyone's is different, so...

If anyone else has better or different suggestions, please feel free to add... I've grown in raised beds with success, but I've not grown Asparagus in them.
