Have used Milorganite now for 3 years on ALL perennials, here in ZONE 5B. Have never taken a soil test in my life, just don't want to be bothered.Clay type soil with pine mulch covering 50 % of the daylilies and the rest have mushroom and compost added alternate years. Milorganite just sprinkled around plants in late APRIL or early MAY. Have great plants and don't intend to change.
