Planting Bulbs

Fill your container with a high-quality potting mix (don't use garden soil) and plant your bulbs as deeply as you would in the ground; for instance, 6 or 7 inches deep for tulips and daffodils, and 4 or 5 inches deep for little bulbs such as crocus and Siberian squill. Water your bulbs well after planting.
If you grow bulbs in a container that's too small to spend the winter outdoors, or one that is made from a material such as terra-cotta that needs protection, keep the planted bulbs someplace cold, such as a garage or shed. Don't bring your bulbs indoors; most basements will be too warm for them to develop properly.

Once temperatures begin to warm in spring, you can augment your containers of spring bulbs with cool-season annuals such as lettuce, Swiss chard, pansy, viola, nemesia, or African daisy.
Or pack more punch in one pot by mixing types of bulbs. Plant your bigger bulbs, such as tulips and daffodils, deeper. Cover them with soil, then plant smaller bulbs, such as crocus, grape hyacinth, or snowdrops, directly above them.
