Bedding plants are a mixture of plants selected to appeal to the sense of color and texture in a garden. Bedding plants can be annuals, biennials or perennials, according to the University of Florida, although the longest lasting bedding plants are annuals because they bloom for an entire season. Summer bedding plants are plants that thrive during the summer, such as alyssum, angelonia, zinnias and petunias, according to the University of Massachusetts.
Choose a place to plant the summer bedding. Be sure it meets the plant's light requirements and has well drained soil. Work 4 to 5 inches of compost into the soil to a depth of 8 to 10 inches to improve your soil's condition.
Dig a hole as deep as the summer bedding's root ball and two times as wide.
Remove the plants from their containers. Turn them upside down and squeeze the bottom of the containers to loosen them until you can pull them out gently. Separate the root balls, and loosen the roots slightly with your hands. Place the summer bedding in the holes, and fill the holes with soil. Pat the soil down firmly. Space each plant about 6 to 8 inches apart.
Water the summer bedding until the soil is moist. Apply a water soluble flower fertilizer at the time of planting to add flower development and growth.
