Tulip and other bulbs with a flat side should be planted with the flat side facing the edge of the container. This will allow the first leaves to form a border around the edge of the pot. Add enough soil mix to fill the pot, and water the bulbs thoroughly from the top or immerse in a tub of water - this will settle the soil around the bulbs. Label each pot with the name of the cultivar, date of planting and date to bring out of cold storage. Daffodils, narcissi, crocus, muscari and other bulbs look great in groups of three, five, or more.
Hyacinths look quite handsome when planted singly, or in groups.
Dense plantings are recommended for minor bulbs. After planting, place the pots in a cool, dark place, such as a cellar or refrigerator to initiate root and shoot growth. Other suitable environments include an insulated cold frame, under a porch, or an unheated garage. Cold storage is a critical step in the forcing process. If necessary, set boxes, pots or black garbage bags over your potted bulbs to keep them dark during the cooling period.
