I have a large patch of Belladonna lilies (Naked Ladies) in a bed by the front door. The foliage is huge and thick and at this time of year, declining. Once it has died back I have a big bare spot in the bed. I can't put perennials there because when the lily foliage comes up it chokes everything out. I have a problem planting annuals without damaging the lily bulbs. HELP! Does anyone have a good solution for the soon-to-be dirt patch? Linda
