Unless there are exceptional circumstances, I believe all will be well. Without the knowledge of the site, its history, the country its in, the weather the last few months one cannot be emphatic but just try it. Here in N E Hampshire, when I started from scratch in March 2016.
The first bed was dug, picture attached.(‘all enclosed’) .It nearly killed me!.
The effort of that led me to explore no-dig’ as an option.
The second bed was created, on mown pasture, covered in cardboard boxes laid flat, composted manure and planted in one weekend, with lettuce plants. They thrived. I survived.
I attach second photo of the ground prior to that .
