Rock hard soil, surrounded by concrete on both sides which restricts the root zone and could be leaching lime into the soil looks like a very poor place to try and grow daylilies. I am assuming those plant in the photo are not going to be divided? For the ones that are, my only suggestion is to take the hose and soak the soil for however long it takes to get that soil so soft it becomes easy to dig and then use a small spade to slowly work them out.
This is the one I have: I have almost completely stopped using a trowel and use this instead when doing small transplanting jobs.
