Daffodil bulbs should be planted about 4 to 7 inches (approximately 10 to 18 cm) deep in the soil, which is roughly three times the height of the bulb. The pointed end of the bulb should face upwards when planting. This depth helps ensure the bulbs produce blooms and do not become "blind" (fail to flower). Planting daffodils too shallow can reduce blooming, while planting at the recommended depth promotes healthy root growth and flower production. When planted in pots, the same depth guideline applies, and bulbs should not be touching each other. Spacing them 4 to 6 inches apart is also recommended to give bulbs enough room to grow. After planting, water the bulbs thoroughly and cover the soil with mulch to help retain moisture. These planting practices support strong, resilient daffodil growth and vibrant spring flowers.
