Not exactly quicksand but it seems to never dry out and in nearly half of the garden when you step on the earth it seems to move under your feet like if you were standing on a filled waterbed mattress. I have never seen anything like it and I really have no clue how to deal with it either. I have fallen in a couple of times and it gets deeper and wetter the farther down I go!! What is going on here? Should I dig up my plants and move them?
