I used a pitchfork to remove the "sod", for that is basically what the bed had become filled with over its period of neglect. I saved as much of the "soil" as possible, which was very sandy, but it had been amended at some point because it was darker near the top compared to a few inches further down.
The bed "surround" is made up of long rectangular marble slabs. After removing the sod and old leaves, I reconfigured a couple of the marble pieces near the Yucca plant and did not include it in the newly cleaned bed.
At this point, I hadn't the plants I needed for the bed, so needed to go to Manitou Gardens (a WONDERFUL nursery up on S West-Bay Shore Drive, Traverse City), who had just what I wanted.
3 Beautiful Blueberry bushes found a home in this little bed. I'm not sure how old the plants are, but they have fruit on them already. I brought them home, added more peat moss and compost in the bottom of each hole I dug for them, and covered the bed with cedar mulch. Of course, a thorough watering took place after that. ;) Hopefully, they will thrive and give us many years of tasty blueberries!
