Parking Lot Garden

Turns out my downstairs neighbor and I are co-responsible for the dirt patch, ahem, I mean garden next to our respective parking spaces. Since my neighbor doesn't live here (they rent their unit out) it's all left up to me! The area is 20' x 7'. Because of the carport the garden gets mostly all shade so I'm limited in what to plant, so this year I'm going to keep it simple and lay down bark and just see what plants sprout up.
