My wife and I planted some asparagus last spring in a regular bed next to an outbuilding. We are looking to add another plant right next to the asparagus, which I would like to put into a simple raised bed. I'll probably just use some treated 2-bys as my bed walls.
I was thinking that it probably would not hurt to just put the asparagus into an attached raised bed as well.
Can I add the raised bed around the asparagus and fill it in with soil? This would in effect bury the asparagus roots by 6-8" more than what they already are.
