Do Daffodil Bulbs Multiply?
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.
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.
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.
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.
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.
Deep Do You Plant Daffodil Bulbs?
You can grow daffodils as perennials in U.S. Department of Agriculture plant hardiness zones 4 to 9. Planting time is usually in the late fall in temperate areas with average low winter temperatures of minus 10 degrees Fahrenheit. Plant the bulbs pointed end up and at least three or four times their height. Work in lots of organic matter, such as well-rotted compost or aged manure. While compost at any stage may not be harmful, fresh manure may burn the bulbs before they become established. Planted too deeply, all they produce are long stems and few or no flowers. This can undo the work invested in planting the bulbs and rob you of the pleasure of seeing them open the following spring. In areas where summers are dry, bulbs can be left in the ground year-round but should be lifted, or dug up, if you plan on growing other types of plants in that spot. Additional watering up to 1 inch per week may be necessary in areas of limited rainfall or during dry spells.
