CARE OF ESTABLISHED PERENNIALS
Perennials are heavy feeders and since they
stay in one spot for a number of years, they require liberal feeding of
complete plant food. Feed established plants early fertilzer in the spring, as
soon as they appear above the ground. Use 1 pound (1 pint) of fertilzer per 25
feet of row or 25 square feet of area. Work plant food into the soil around the
plants. Feed at the same rate every 8 weeks during the growing season.
