There are three mature asparagus plants in our backyard, which we've been enjoying so far since we moved in a few months ago. Unfortunately, they are located in the exact spot where we'll soon be building a garage, and due to some other work we're doing in the yard, their new home won't be ready until September at the earliest.
What I'd like to do is dig them up and house them temporarily in large pots. Then in September we'll plant them in their new permanent home.
How likely are they to survive this process? What can I do to help ensure their survival? Am I better off just starting new asparagus plants?
I am in Madison, WI (USDA plant hardiness zone 5a), and all locations (current, temporary, and future) are in full sun.
