Spring flower bulbs are those bulbs that bloom in the spring, such as daffodils and tulips. While many of these bulbs can be planted in the fall, if you live in an environment with harsh winters, you will have to wait until spring. When spring arrives, plant the bulbs as soon as the ground is soft enough to dig in so they will grow and bloom later in the same season.
Choose a planting site. Most spring flower bulbs prefer full sun. Amend the soil with some compost to encourage good drainage.
Dig holes to a depth that is appropriate for the bulbs. For example, daffodils are large bulbs and should be planted 8 inches below the soil's surface; crocuses are small bulbs that need to be planted about 2 to 4 inches below the soil's surface.
Space bulbs according to how large their foliage and blooms will grow. Lilies are large flowers that need to be spaced 10 to 12 inches apart. Snowdrops are small plants that need to be spaced much closer, around 3 inches apart.
Place the bulbs in the ground with the tips facing up toward the sky. Back fill the soil and push it down to remove the air. Water the newly planted bulbs well. Cover with mulch, if desired.
