Daffodils need at least six hours of sunlight to flower, so move your flowers to a sunnier area that's not blocked by trees.
Plant your daffodil bulbs at a depth of three times their size, about 8-10 inches deep. Ensure their roots won't be too crowded.
Avoid heavy nitrogen fertilizers since they can encourage leaf growth but not blooms.
Daffodils are a popular perennial bulb, with hundreds of varieties available in a range of types according to their shapes and bloom times. Though yellow is the most common color, they can also include touches of orange, pink, white, and green. Depending on the variety, daffodils may begin blooming in early, mid, or late spring. They tend to be easy to grow and are fairly reliable perennials, but sometimes poor growing conditions or other factors can cause them to stop blooming.

We spoke with some experts to explore some of the most common reasons why your daffodils aren't blooming, and also suggested some possible fixes for this problem.
Not Enough Sun
Daffodils need at least partial sun to bloom; some varieties prefer full sun. Peggy Anne Montgomery, a horticulturist and head of Montgomery Horticultural Consulting, says daffodils are not known to be finicky bloomers, but a lack of sunlight is often a reason why they don't flower.

She recommends striving for at least six hours of sunlight for daffodil plantings. Annette Hird, a horticulture writer and founder of Easy Urban Gardens, recommends moving daffodil bulbs to a sunnier location if the blooms have been scant, and points out that ample sunlight aids photosynthesis of the foliage.

Keep in mind that the angles of sunlight move during the season, and daffodils emerge early, so when planting bulbs in autumn, you need to consider where the sun will be in spring. Also, if your daffodils have been in one place for a long time, it's possible that trees or shrubs growing larger over the years may be blocking sunlight.
Too Crowded
If your daffodils are planted in an enclosed flower bed or near a building foundation, shrub, or tree, they may become too crowded over time. This is even more likely if the clumps have grown large and haven't been divided in a while.

If your clumps are more than a foot wide, they may need dividing. Montgomery says that daffodils being too crowded is a common reason for blooms to decrease, and that if you have an old stand of daffodils, it may be time to lift and divide them.

Poor Drainage
In thick clay soil or in boggy garden areas, daffodil bulbs may stay too wet, and this can rot the bulbs. Add some soil amendments when planting or dividing to improve drainage. Divide large clumps of bulbs regularly (every couple of years), as wet soil clinging to large clumps can also affect soil drainage or even cause bulbs to rot.

Not Planted Deep Enough or Early Enough
There's a standard "rule" that daffodil bulbs should be planted at a depth of three times their size, about 8-10 inches deep. It's also important to plant daffodils well in advance of the first frost, by mid to late September.

This lets the bulbs get established before cold weather sets in. The same rule goes for replanting bulbs after dividing them. Laura Janney, a gardening expert and creator of the Inspired Garden Masterclass, suggests dividing daffodils in early summer.

Trimming Foliage Too Soon
Daffodils draw nutrients from their leaves to help feed the bulbs and allow them to store up energy for the next season of bloom. Janney says that some gardeners don't realize that it's important to let the foliage fade and die back naturally, rather than cutting it right after flowering has ended.

She suggests waiting until the leaves have started to turn yellow before removing the foliage. Some gardeners plant their daffodils strategically near other perennials that emerge in late spring (such as hostas or day lilies) to help camouflage the decaying foliage.

Too Much Fertilizer
In general, daffodils don't really need much fertilizer unless you have poor soil. You can use a small amount of fertilizer made for spring-blooming bulbs as new growth emerges, or top dress them with a bit of bulb food in the fall, or mix it into soil when planting, Janney says.

Also, avoid heavy nitrogen fertilizers; Montgomery says too much nitrogen tends to encourage leaf growth but not blooms. Hird recommends a balanced, low-nitrogen fertilizer in spring if needed, as well as enough water to keep the growing plants hydrated, which will keep their leaves lush.
