It’s the middle of spring, and you’re expecting to see your daffodil buds burst open into bright yellow blooms. Instead, they’re short, stubby little things that barely look like flowers. And you might be wondering what the possible reasons for this are.
Some reasons your daffodils are so short include an issue with watering, pH balance, sunlight, temperature, or the nutrients in the soil. Additionally, keep an eye out for any pests or illnesses in your plant. Also, check to ensure your daffodils aren’t too crowded.
In the rest of this article, I’ll give you the five most common reasons that daffodils come up short. Then, I’ll review some common pests and illnesses to look out for. We’ll wrap up with a quick reminder of how to plant your daffodils properly.
Why Daffodils Come Up Short
When your plant is stressed, it doesn’t have the energy to grow. It’s as simple as that! If something goes wrong or against its most desired routine, such as too much water or too little light, it stresses the roots and stunts the growth.
Every spring, I look forward to the arrival of daffodils. Daffodils are lovely flowers that require a bit of care. Luckily, you can do plenty of things to ensure that your daffodils grow and bloom as they should. These flowers are a welcome sight after months of gray skies and bare trees. And then, after just a few weeks in bloom, they’re gone again!
It’s hard not to feel like your investment wasn’t worth it when you see what seems like half-dead tulips and daffodils sticking up from your yard. But don’t give up on these hearty plants just yet — there are several reasons why they may not bloom as expected this year.
Most commonly, I see the following problems when investigating daffodils that are stubby or short:
- Watering issues
- pH and nutrient issues
- Sunlight and temperature issues
- Illness and pests
- Bad bulbs
Often, when an issue arises in a garden, I’ll do a thorough investigation before making any sudden movements. Changing one thing in your routine often knocks everything else on its side.
Doing something without much investigation (such as watering more even though your problem is inadequate sunlight) may make the problem worse.
There’s nothing wrong with checking in with your practices to create a holistic and intentional gardening routine. But for stubby daffodils, read below to see which category fits most of what you’re seeing and see why it makes a difference.
1. Watering Issues
If you’re noticing that your daffodil stalks are getting shorter and shorter, consider whether there has been an issue with overwatering or consistently soggy soil conditions. If your daffodils are producing short stems, it could be because the soil is too wet. Daffodils like moist soil but can’t handle being waterlogged for extended periods.
If you live in an area where you experience frequent rain, especially during the spring and early summer when most bulbs are starting to grow their leaves, this can lead to very wet conditions in the ground around your bulbs year. If this happens regularly enough, it may cause rot within the bulb, which means fewer flowers.
Drainage is also important: you can water as little or as much as you want, but if the water isn’t going through the pot, you’re going to have some issues. Stressed plants need space for their roots to grow and to get rid of excess nutrients.
2. pH and Nutrient Issues
When you plant your daffodils, they’ll need suitable soil to thrive. When the pH of your soil is off, it can cause all kinds of problems for the plants in your yard.
If you don’t know what that means or how to adjust it, don’t worry! Test the pH of your soil by using a kit from a garden store or online (you can also buy kits at most hardware stores). This will tell you which numbers range matches yours — and then give advice on how to change them if needed.
3. Sunlight and Temperature Issues
Daffodil bulbs need full sun to bloom. The amount of sunlight they need varies depending on the variety. Still, the more sunlight they get, the better they will grow.
You can help your daffodils get more sun by planting them where there is more light than shade — on a south-facing slope or in your yard’s sunny corner instead of an adjoining tree’s dappled shade. Most varieties should also do well in partial shade — just make sure that you don’t bury their tops under mulch or other groundcover plants after planting! Keep your soil moist and fertilize properly.
Daffodils are a little finicky. Daffodils prefer cool temperatures around 40-50 °F (4.44-10 °C), with high humidity and plenty of rainwater. They don’t like it when the weather gets too hot or too cold either way — so they’ll shut down if they’re left in the sun all day long.
4. Illnesses and Pests
Another reason your daffodils might be short is because of pests or diseases. It’s essential to use a good quality fertilizer, compost, or mulch that contains nutrients plants need during the growing season, like iron and magnesium; it will help keep them healthy while producing flowers. These can also help keep pests and illnesses at bay.
Some of the most common illnesses for daffodils are:
- Root rot. This is caused by overwatering or poor drainage in the soil. This is especially likely to happen if your daffodils have been planted in clay-heavy soil. If you suspect root rot, pull up one of your plants and examine its roots for signs of decay or discoloration.
- Leaf spot. This disease can be caused by a fungal pathogen that attacks new leaves as they emerge. Affected leaves turn yellow and brown before falling off completely; if left untreated, it can spread to other plants in your garden as well as nearby ones if carried on wind or water droplets from raindrops hitting infected leaves directly overhead during springtime showers or storms (which happens often).
- Mosaic virus. Daffodils are also susceptible to mosaic virus, spread through insects like bees and thrips. Once infected with a mosaic virus, your plants will show symptoms such as yellowing leaves and stunted growth before dying completely!
If you do find that your daffodils are diseased, this would explain why they were too stressed to grow to full length.
You should also keep a look out for pests. Some of the pests most commonly attracted to daffodils are:
- Aphids. These little guys are so small that you might not even see them at first, but they can damage your flower beds. They suck the life out of your daffodils and other plants, causing them to wilt or die.
- Whiteflies. These pests look like tiny white moths that hover around the tops of leaves, sucking out the plant’s juice.
- Slugs and snails. These creatures are a pair of different critters, but both eat holes in your daffodil bulbs, leading to shorter blooms and early leaf drops.
If you notice bugs on your daffodils, try natural remedies like neem oil or soapy water to rid them!
5. Bad Bulbs
If you’ve been growing daffodils for more than three years, your bulbs have likely lost their vigor — even if they look fine on the outside.
To determine whether your bulb is past its prime, take a closer look at the area inside the outer layer of skin where new leaves sprout — you should see little white roots emerging from within. If there are no white roots present within an inch (2.54 cm) of this spot, then your bulb isn’t viable anymore and should be thrown away before planting new ones in its place next spring.
How To Properly Space Your Daffodils
Overcrowding is another common issue I see with daffodils. Still, this issue can’t be fixed as quickly as above. The stress from being planted too close can leave daffodils leggy and constantly competing for nutrients. Though it may be too late to fix this issue this season, you can remember the proper spacing techniques you need next year.
Daffodils need about 10 inches (25.4 cm) of space between them to grow, bloom, and look their best. When they are packed together, they will not be able to reach their full potential.
Additionally, be cautious of how deeply you plant your daffodils. Daffodils don’t need to be planted very deep, but you do not want them at such a shallow depth that they are exposed to the sun and dry out quickly. Plant your daffodil bulbs so that only a third of their length is visible above ground level (or slightly less if you’re planting in clay soil).

Daffodils are easy to grow and a good choice for beginner gardeners because they don’t require much maintenance or special soil conditions. They can be planted in almost any type of soil as long as it’s fertile and well-drained. It’s also essential to keep their roots cool (but not cold) during winter months, so they can withstand freezing temperatures without being damaged.
