When to Plant
Daffodil bulbs require an ample amount of time for the roots to set before the soil freezes. Early fall is the optimal time to plant but in many locations they can be planted as late as November.
Where to Plant
Daffodils require a sunny location and fertile, well-drained soiled. If you plant daffodils in poorly drained areas, or clay soil, the bulbs are likely to rot. You can easily amend clay soil with the addition of organic material such as peat moss.
Planting Daffodil Bulbs
Dig a hole to the depth of 2-3 times the height of the bulb. In the case of daffodils, this is generally an average of 8" from the surface.
Fertilize with organic compound, or if using commercial fertilizer such as 10-10-10 be sure to cover it with ample soil so that it is not directly touching the planted bulb. Too much fertilizer can kill emerging roots and encourage bulb rot.
Plant the Daffodil bulb with the nose facing upward. Cover with soil and pack.
Water the newly planted bulb sufficiently so the water soaks down to the bulb's level. Do not oversoak it.
Mulch the ground around the base of the plant to help maintain the soil's moisture content. Mulching will also keep a more uniform soil temperature and inhibit weed growth.
Deadhead spent blooms to prevent seedpods from forming.
Keep foliage intact after the blooms have been spent. The foliage manufactures the plants food through photosynthesis, which is necessary for the bulb's survival. Remove foliage only after it has yellowed and withered, which is about 8 weeks following bloom time.
