In the back of our house, the tiny patio is surrounded by concrete planter things that were built into the ground. H is currently cleaning these out and preparing them for planting (don't ask why we just decided to do this in the middle of August). We have no idea what the hell we are doing. I don't like playing with dirt, so he's doing all the work; I'm giving the directions. What can we plant in there at this time of year?
