I’m a novice gardener. My Pleasanton yard is neatly landscaped with a variety of plants. I have several lovely patches of irises, hyacinths, and daffodils because I love the springtime blooms that come from bulbs. A row of daffodils about 8 feet long (maybe a dozen plants) has been sprouting leaves for the past three years without a single stalk or bloom. Other daffodils nearby flower wonderfully, but one row does not. I believed it to be an anomaly that will self-correct, but three years have passed with no flowers. Any thoughts on the cause or what I can do to fix it? These were dubbed “blind daffodils” by a neighbor.
A similar query is: Should the remaining foliage be removed after the blossoms and flowering of bulbs have passed, or do the bulbs need the leaves to stay for a while? I was warned not to prematurely remove the leaves since the bulbs would “resorb” nutrients from the dead plant.
A: Howdy, blind daffodils. Although daffodils weren’t known for their keen eyesight, this is a traditional word for daffodils that are flowerless.
If your plants have a lot of leaves, it’s likely that the bulbs were once healthy but have since multiplied to the point where the clump is now so crowded that none of the bulbs are receiving enough water and nutrients. If so, you can divide the bulbs, dig them up in the early summer when they are dormant or almost so, and replant them. All of the bulbs will ultimately bloom, but if you’re short on room, you might want to throw away the smaller ones as they won’t bloom for at least a year or two.
Your plants’ inability to store food is likely to be the cause of their sparse leaf production. For instance, did another plant become taller and suddenly cast a severe shade on this row? As a result, there might be less food to store and a reduction in photosynthesis. Occasionally, bulbs that were planted too shallowly do not bloom. Daffodils require soil that is twice their height above them. The top of a daffodil bulb should be 4 to 6 inches deep because it is 2 to 3 inches tall. To gauge their depth, dig up a few of them. Replant them deeper if they are not planted deep enough.
According to daffodil experts, cultivars with double flowers or several blooms on a stalk are more likely to stop flowering under conditions like the ones mentioned above since they require more energy. You can check to see if the theory is accurate if yours ever bloom!
If you need to replant your bulbs for any of the aforementioned reasons, remove them all and then re-dig the bed, turning under a few inches of compost and some greensand or other fertilizer delivering around 5-10-20 percent of the soil’s total nitrogen content (ratio of nitrogen, phosphorous, and potassium).
Why are my daffodils producing blind flowers?
Daffodils typically grow and flower well when they are first planted, but in later years flowering may be diminished or fail entirely, despite having healthy, abundant leaves. Blind daffodils are those that emerge with leaves but no blooms. This condition might be brought on by pests, illnesses, or the growth environment.
Do blind daffodils recover?
Keep the bulbs well-fed by adding a granular high-potash feed in early March and liquid fertilizer every 10–14 days following flowering, until the foliage dies down.
How are daffodil bulbs revived?
Daffodils might not blossom, but there are a few unfortunate causes for this! Please see the following check list to determine if anything applies to your situation:
- Bulb ‘feeding’ has not occurred in a few years (a broadcast of 5-10-10 granules at planting, when leaves emerge, and again at bloom is a reasonable feeding schedule.)
- The fertilizer used for feeding has been heavy in nitrogen. (This promotes the growth of leaves while reducing the plant’s demand for blossoms.)
- A shaded area is where bulbs are planted. (Daffodils require at least a half-day of sun to bloom. Longer if planted in partial light.)
- Other plants and bulbs compete for food resources. (Limiting their access to food by planting near fast-growing plants or under evergreen trees. No blooms and poor plants are the result.)
- In a region with bad drainage, bulbs are planted. (Daffodils require good drainage because they adore water. Where there are water puddles, they struggle. They deteriorate and eventually perish there due to “basal rot fungus or other ills.” Basal rot-infected plants have leaves that have lost their green hue and are deformed, including the stems, blossoms, and leaves. Dig and throw away the bulbs because basal rot is incurable.
- The previous year, plant leaves were either tied off or removed too soon. (After blooming, daffodils continue to replace their bulb for around six weeks. After blooming, the bulbs should receive water for around this amount of time. Until the leaves begin to lose their green color and become yellow, they shouldn’t be cut off from the sun or shaded. This denotes that the process of rebuilding the bulb is finished.)
- Stress from transplanting may affect bulbs. (If some types are dug up and transplanted in a different habitat, they appear to skip a year of blooming. Some types that were purchased from a grower in one location could take some time to acclimate to one in a very different climate. They might produce flowers the first year from a bulb from the year before, but they won’t be able to produce enough flowers the following year.)
- Some naturalized types that thrive in one climate don’t thrive in others with a different climate. If transferred north, the wild jonquils that are populating and blooming in the Southeast United States do not flower.
- The bulbs can be virus-ridden. (A number of plant viruses target daffodils. An infected plant gradually loses strength, develops smaller, weaker leaves and stems, stops blossoming, and eventually perishes. Yellow stripe and mosaic viruses are the most prevalent. Fine yellow lines run the length of the leaves, indicating a yellow stripe. It appears as the leaves start to erupt. By the second year, the plant is already feeble. Mosaic only manifests as white spots where the petals of yellow flowers lose their color. Vegetation vitality appears unaffected. Both of these illnesses are fatal and infectious to other daffodils. Dig, then discard the bulbs.)
- growing circumstances The bulb’s reformation may have been hampered by the previous Spring’s unfavorable conditions. (An early heat wave might have stopped bulb reconstruction before it was finished. It’s possible that the bulbs were grown in a modest pot without enough care or protection from the elements.)
- Bulb disease or stress from transportation the previous Summer could be present. (Retail bulbs frequently spend a significant amount of time while transportation in closed crates. These moist circumstances are almost ideal for the spread of fungus illnesses like “basal rot” (fusarium). When you obtain some bulbs, they already have an infection. Never invest in or plant “soft bulbs. Before planting, treat a solid bulb with a systemic fungicide like Clearys 3336 and cut any decaying areas back to healthy tissue. For a list of retailers, see our page on ADS bulb sources.
- It may be necessary to divide bulbs that have been growing in the same location for many years. (In general, daffodil bulbs divide every year or two. Bulb clusters that are vying for food and space may arise from this. Bulb clumps that are too tightly packed usually stop blooming. When the foliage has turned yellow, dig the bulbs. Replant them at a distance of six between each bulb and a depth of six. After lifting the bulbs, you have two options: you can plant them right away, or you can dry the bulbs in the shade, store them in mesh bags, and plant them again in the fall. If you immediately replant, hold off on watering them until the fall.)
- Bulbs might be trying to harm you! (The scenario in which you resentfully hand them away and they erupt into a riot of blooms for the new recipient.)
Why aren’t my daffodils blooming?
Daffodils are referred to be blind daffodils if they get into leaf but don’t bloom for one of the following reasons:
- The most frequent reason for this is improper planting depth; bulbs must be buried at least three times their height in the soil. The most frequent reason for daffodils not blooming is this. When the daffodils have finished blooming, mark them, then dig out the bulbs and replant them at the proper depth.
- Blindness can result from extremely dry soil, therefore it’s a good idea to mulch the area before planting to help preserve moisture and lessen the dryness.
- Daffodil planting too late may result in the absence of blossoms. By the middle of September, the soil must be prepared for daffodil planting.
- Daffodil mature clumps may get overcrowded; in this case, lift, divide, and replant. Lift the bulbs as soon as they begin to leaf, and then immediately replant them.
- Problems might result from knotting and defoliation. Making the worn-out foliage look more attractive may be alluring, but removing it too soon prevents the leaves from absorbing nutrition. After flowering, you should give the foliage at least 6 weeks to gradually die down.
- In the event that all other measures fail, feeding may help; in this instance, any suitable applied consistently after the blooms have faded.
How can you make daffodils grow more?
Unsurprisingly, improving either mode of reproduction is the best approach to promote the spread of daffodils. For instance, you should be prepared to take cuttings as the bulbs begin to divide and plant them as necessary if you wish to increase the rate at which they reproduce through asexual reproduction.
Naturally, this takes a lot of time, so you’re probably more interested in letting your daffodils expand on their own.
This entails doing all in your power to increase the likelihood that your daffodils’ seeds and pollen will blow, settle in fertile soil, and then produce new flower buds.
However, daffodils are constrained in ways that other flowers are not. For instance, the pollen of flowers that use this as their primary means of dispersal and reproduction, such as daffodils, is substantially heavier.
As a result, you cannot rely on the pollen to travel far. As a result, if you anticipate that a simple wind gust in the spring would spread the pollen from your daffodils across your yard to fertile land, you should reconsider.
Perhaps you believe that the buzzing of bees in your backyard will be beneficial, as they are with other flowers. Daffodils do not have nectar to draw them, so that is out of the question (or luckily, if you want to control the spread).
Additionally, it may take daffodils months or even years from the time they are planted until they reach their full potential.
Since most of us aren’t prepared to wait that long to spread daffodils over our yards, this approach is definitely not the one you want to use first if you want them to spread quickly.
As previously said, you must instead assist the bulbs by doing a little bulb division yourself. We’ve already talked about how this works, but you can speed things up.
Dig a hole, put the bulbs there, and wait for them to grow once you have divided the bulbs or allowed this process to occur naturally.
You’ll want to make sure that they are large enough to accept them, so dig them at least two to three times larger than the size of the bulb itself, just like you did with the holes for your initial daffodils.
Once you’ve completed that, the daffodil bulb can be planted into the hole. When you begin to fill it back in, make sure the bulb itself stays below the soil line.
Does daffodil pruning produce more flowers?
Before they turn yellow, daffodil leaves shouldn’t be pruned back. Daffodils generate energy from their leaves, which is then used to make the flower that blooms the next year. Daffodil bulbs won’t bloom the next year if they are pruned before the leaves turn yellow.
When may I trim back my daffodils?
None. The two terms are equivalent. Like ilex is for hollies, narcissus is the Latin or botanical term for all daffodils. The ADS advises against using the common name “daffodil” for any member of the genus Narcissus except when writing scientifically. Return to Top
What is a jonquil?
In some regions of the nation, any yellow daffodil is wrongly referred to as a jonquil. The majority of jonquil species and hybrids have many yellow flowers, a potent perfume, and rounded leaves. The hybrids are limited to Division 7, hence the term “jonquil” should only be used to refer to Division 7 daffodils or Division 13 species that are known to be members of the jonquil group. Return to Top
How many kinds of daffodils are there?
There are between 40 and 200 distinct daffodil species, subspecies, or variants of species, and more than 32,000 registered cultivars (also known as hybrids), distributed throughout the thirteen divisions of the official classification system, according to the botanist you speak with. Return to Top
Will squirrels and other rodents eat daffodil bulbs?
No. Only specific insects can freely consume the toxic crystals found in the bulbs and leaves. However, they might dig up the bulbs. Return to Top
Are daffodils expensive?
Prices for bulbs range from approximately $1 to over $100, depending on a cultivar’s rarity or newness, not necessarily on how desirable it is. Prize-winning display cultivars can often be purchased for less than $2.50. Even less expensive cultivars are available for naturalizing, although mixes of unknown cultivars are not advised.

How long do daffodil bulbs last?
They should outlive any of us if given the proper growing conditions. Daffodils should grow, however some types of bulbs have a tendency to diminish and disappear. Return to Top
How do daffodils multiply?
Daffodils grow by asexual cloning (bulb division), which produces identical duplicates of the flower, and sexual reproduction (from seed), which produces new, distinct flowers.
The swelling just beneath the flower petals is called the seed pod (ovary), where seeds grow. The seed pod usually swells after bloom but is empty of seeds. On occasion, pollen from new flowers might be carried by wind or insects to the flower while it is in bloom. When this occurs, one or a few seeds will be present in the seed pod.
By lightly brushing pollen from one bloom onto the stigma of another, daffodil hybridizers fertilize flowers. The developing seed pod can then have up to 25 seeds inside of it. Each of these will result in a brand-new plant, although a plant produced from seed takes roughly 5 years to blossom. Return to Top
How long is the flowering season of daffodils?
From six weeks to six months, depending on where you live and the cultivars you grow. After flowering, allow the daffodil plant to regenerate its bulb for the following season. While everything is going on, the leaves continue to be green. You can remove the leaves as they start to turn yellow, but not before. Return to Top
What are miniature daffodils?
Sizes of daffodils range from half-inch blossoms on 2-inch stems to 5-inch blooms on 2-foot stems. The ADS has established that certain species and named cultivars are miniatures and must compete alone in daffodil displays, mostly for show purposes but also to provide gardening advice. Miniature lists that are up to date are published in the Daffodil Journal and are also available individually from the ADS. Return to Top
Are daffodils difficult to grow?
No. They are perhaps the simplest and most dependable flower families, making them perfect for a starting gardener in the majority of American states. Return to Top
Do you need to deadhead daffodils?
When daffodils have finished blooming, you can dead head the bloom to redirect energy away from seed development and toward developing the bulb for the following year’s blossom. The leaves should be left to naturally wither away until they are at least yellow before being removed. Return to Top
When should you cut back daffodils?
It is advised not to trim back daffodil leaves until they have at least turned yellow. To build the bloom for the following year, they utilise the energy in their leaves. After the blooms have faded, daffodils continue to absorb nutrients for around six weeks. They require plenty of sunlight and a steady supply of water throughout this time. The plant’s leaves gradually turn yellow and die back as the daffodil bulbs develop.
Daffodil leaves removed by mowing or pruning back shortly after blossoming will severely reduce your bulbs. Similar to dryness, it inhibits the formation of food stores and their storage in bulbs for the future. Return to Top
Can daffodils be grown throughout the United States?
Daffodils are grown all the way to the Canadian border because they can withstand frigid temperatures, especially when covered in snow. Only a few delicate cultivars, typically tazettas, like the well-known Paper White, are an exception. Daffodils can also be grown in the South, with the exception of Florida’s non-frosty regions. For the commencement of flower buds, a natural or forced cold treatment is required. There are specific varieties and named cultivars that have been shown to perform better than others along a limited zone along the Gulf of Mexico that extends from Florida to Texas. Return to Top
Will daffodils grow in the shade?
They have done flowering and the foliage has started to mature by the time deciduous trees begin to leaf out, thus they will grow in the shade of deciduous trees. However, it is preferable to grow them above rather than below deciduous trees’ drip lines. Additionally, tap-rooted deciduous trees are preferred to shallow-rooted trees. Daffodils won’t last very long in the presence of evergreen trees and plants. Return to Top
Do ground covers have an adverse effect on daffodils?
The fertility of the soil and the aggressivity of the ground cover will determine how well the two compete for nutrients and moisture. Daffodils are likely to be discouraged by vigorous, tall-growing, and deeply-rooted species like pachysandra and ivy, but they typically thrive in the presence of shallow-rooted, trailing plants like myrtle, foamflower (Tiarella cordifolia), or creeping phlox (Phlox stolonifera).

Why should I exhibit at daffodil shows?
for the fulfillment of contributing to the presentation of a magnificent show of a flower whose variety and virtues are too poorly known to the general public and other gardeners. A display will also provide you the opportunity to meet people who share your passion for daffodils and to observe the blooms of the newest kinds. Eventually, awards may be given in recognition of your talent, and you could then want to enroll in the courses and exams necessary to become an Accredited Judge. Return to Top
