Summer bulbs provide striking color in a perennial bed, rock garden or border. They can be purchased from catalogs, online and from garden centers. Make sure that the bulbs you purchase feel firm and have even coloring, as bulbs with mold, fungus or splotches may not be viable. Summer flowering bulbs, such as hyacinth, gladiolus, lily and dahlia should be planted in the garden in March.
Choose the location where you wish to plant your bulb garden. Most bulb flowers enjoy sunshine, while a few need shade. Follow the instructions that came with the bulbs.
Loosen the soil with the spade or a garden fork to a depth of 8 inches. Add 2 inches of compost and bulb food, according to the rate suggested on the package, and mix these materials in well with the existing soil.
Dig holes for the bulbs. Each bulb will have its own depth requirements, so consult the packaging material to determine how deep to place the bulbs.
Water the flower bed after planting until the soil is moist. Overwatering may cause the bulbs to rot, according to horticulturists at the University of Illinois.
