We planted 2-year old asparagus crowns 3 weeks ago in a brand new bed following the instructions from Wisconsin Garden Guide (dig trench, add composted manure, add crowns, and cover with 2 inches of screened compost). We have kept watered (not that any was necessary last week!), but there is no sign of any life from these. Something I read suggests maybe these have rotted in the cold soil? Should we start over or is it possible we will still get some action? Thanks for any help.
