This spring (recently) I replanted and moved some perennials around because the daylillies got so big they hid the others in back (hostas). I planted on a slope. The soil seems to be good but I haven't tested it. How can I keep the pine bark mulch from rolling off when I water and what can I do to to help my knockout roses? They are not thriving at all like others I have seen in my neighborhood.
