Back in the summer when the Black Eyed Susans were spent, I put down cardboard in the lawn in a dumbbell shape about four feet from the driveway, covered it with grass clippings and pine straw and those huge BES plants I'd pulled up, leaving the seed pods attached.
Yesterday, I rolled the cardboard and mulch forward, dug shallow holes for 80 daffodil bulbs just up to their necks, replaced the soil and covered the daffodil bed with 2 inches of decomposed oak mulch and an inch of composted gin trash and then pulled the original mulch over the bed and dispatched what was left of the cardboard to a compost heap. (The purpose of the cardboard was to kill the bahia grass.) Along the north edge, I planted some pansy seeds mixed with alyssum seeds. The pansy seeds are two years old; the alyssum seeds are 2007 seeds. I sprinkled some white nicotiana seed over the mulch in hopes they'll grow with the Black Eyed Susans which are almost fool proof.
This bed is perpendicular to the long rock bed, one of my favs. You can see the story of the Long Bed here:
