Place bulbs shoulder to shoulder across the surface of the soil, leaving no space between them. Then top off with more potting soil so the bulbs are just slightly below the surface. Water each container thoroughly, and finish with a layer of mulch.
Easter Shaving Cream Eggs I made these, use neon food coloring, not regular and don't use a thick layer of shaving cream, just maybe inch. then when drying, let them completely dry. We had fun doing these!
