For an east-facing window box or any location with morning sun and 4 or fewer hours per day, we’d suggest snapdragon, impatiens, begonia, viola, cardinal flower, sweet alyssum, dahlia, petunias, verbena, ageratum, dusty miller, and dwarf marigold. In terms of replacing the soil: If it’s been a few years, yes, we would replace or heavily amend it; the nutrients have been depleted by now and it’s probably compacted. Better safe than sorry.
