Can anyone help me. I can't figure out why my creeping phlox died. I had it planted on the edge of a block wall. I thought it would be so pretty from the street hanging over the edge. The wall gets the afternoon sun and faces the west. Do you thing it got too hot on the wall? I know the stones obsorb a lot of heat. It was the second year for them and it did bloom some but not like it should then it turned brown. Shouldn't it have stayed green and lush looking. Thanks for any help you can give me.
