When naturalized, bulbs create a spectacular splash of color on the lawn. Most bulbs, including daffodils and bluebells, bloom in the springtime, but with careful planning you can grow flowers in the lawn all year round.
grit or sand
Do this by scattering the bulbs across the lawn, and plant them where they land. Use a bulb planter to take out a core of soil; bulbs should be planted at two to three times their depth.
Keep the growing tip facing upward. If the soil is poorly drained, grit or sand can be added. After planting, backfill the hole with soil and replace the plug of turf.
After it blooms, the plant should be deadheaded, then left for a few weeks until the foliage has died back, allowing nutrients to return to the bulb. Then, mow the faded foliage, and give the lawn a light rolling to level it.
