Do this if you had blind daffodils this spring

Daffodils can experience a condition known as “blindness,” where they grow a lot of foliage but fail to produce flowers. This issue can result from several factors, such as poor soil quality, overcrowding, and insufficient sunlight. Fortunately, this problem can usually be resolved through some straightforward steps, although it may take a couple of years for the bulbs to bloom again.
The first step is to feed the daffodils and allow them to die back naturally. Use a stick or take a photograph to mark their location, so you can remember where they are.
In autumn, dig up the daffodil bulbs and replant them immediately at a depth of about 6 inches. If the daffodils were growing in a shaded area, consider relocating them to a sunnier spot. If the bulbs are overcrowded, divide them and plant them in smaller clusters. Additionally, if the soil quality is poor, enhance it by adding bulb compost or homemade compost. Make sure the bulbs are adequately watered and top-dress with organic matter.
By following these steps, you should expect to see daffodil flowers blooming once again within a couple of years.
