How often should you thin out the daffodil bulbs bulbs?

Daffodil bulbs should typically be thinned out every 3 to 5 years. This helps prevent overcrowding, which can lead to decreased flowering and overall plant health. After the foliage has died back in late spring or early summer, is the best time to dig up and separate the bulbs. Replant the healthy bulbs in a well-draining area to encourage better growth.
