Daffodils are low-maintenance annuals that take care of themselves. These sunny flowers propagate themselves two ways, and they'll even tell you when it's time to divide the bulbs.
Growth
Daffodils are very easy to grow, preferring sunny well-drained spots to produce the most flowers. Keep daffodils moist but stop all watering about three weeks after the flowers bloom.
You can leave daffodil bulbs in the ground for up to five years before replanting them.
Propagation
Daffodils reproduce both by seeds and by bulb multiplication. Seeds will produce flowers in three to five years, and bulbs in another two. New bulbs will naturally sprout from the bottom and sides of the main bulb.
Division
Divide bulbs in the late spring or early fall, if they seem crowded, or if they stop blooming.
Dig, then gently separate the bulbs from the main bulb at the bottom end, using a sharp knife if needed.
Store bulbs in a cool, dry place until it's time to plant them in the fall.
Replanting
Plant your daffodil bulbs, pointed end up, after the soil has cooled in the fall. Mature bulbs should be planted 6 inches deep and watered thoroughly until the wet weather begins.
