Introduction
There is nothing quite like the sight of the first cheerful yellow daffodils popping up to announce that spring has finally arrived. These hardy perennials are some of the most reliable performers in the garden, bringing a sense of joy and renewal after a long winter. Most of the time, these bulbs are happy to stay exactly where you planted them, but occasionally, you may need to lift them out of the ground to divide a crowded clump or clear space for summer annuals.

Daffodil bulbs are incredibly resilient, and by following a few basic steps, you can keep them healthy and vibrant during their time out of the soil.
Why You Might Store Daffodil Bulbs
Daffodils are famous for being "plant and forget" bulbs. In most parts of the United States, they are perfectly happy to remain in the soil year-round. However, there are several practical reasons why you might choose to dig them up and store them over the summer months.
The most common reason is overcrowding. Daffodils are excellent at "naturalizing," which means they multiply and spread on their own. Over several years, a single bulb can turn into a dense clump. When the bulbs become too crowded, they start to compete for nutrients and space. You might notice that the foliage stays green and healthy, but the number of flowers starts to dwindle. Lifting and storing the bulbs allows you to separate them and give them more room to grow when you replant them in the fall.
Another reason is garden management. If you have a small garden space, you may want to use the area where your daffodils bloom for summer-flowering plants like dahlias or begonias. By lifting the daffodils after they finish their spring show, you free up prime real estate for your summer garden. Some gardeners also prefer to lift bulbs to protect them from excessive moisture. If your garden soil stays very wet during the summer due to heavy irrigation or frequent rains, the bulbs could potentially rot. Storing them in a controlled, dry environment prevents this issue. For more daffodil options with a strong spring display, the Classic Double Daffodil Collection is a great place to explore.
Key Takeaway While daffodils can stay in the ground for years, lifting them every 3 to 5 years helps prevent overcrowding and keeps your floral displays looking their best.
The Importance of After-Bloom Care
Before you even think about reaching for your garden shovel, you must give your daffodils time to prepare for their move. The life cycle of a bulb depends on the energy it gathers after the flowers have faded. This period is the most critical time for the bulb's future health.
Once the petals wither and fall, the green leaves continue to work hard. They use sunlight to create food through photosynthesis, which is then stored in the bulb’s fleshy layers. This stored energy is exactly what the plant will use to grow leaves and flowers next spring. If you cut the leaves off too early, you are essentially "starving" the bulb, which will result in weak growth or no flowers at all in the following season.
As the weeks pass after blooming, the leaves will naturally begin to turn yellow and eventually brown. This change in color is a signal that the bulb has finished its work for the season and is entering its dormant phase. Only when the foliage is completely withered and pulls away easily from the soil should you begin the lifting process. This usually happens by late June or early July, depending on your local climate. If you like fragrant selections for future planting, the Fragrant Daffodil Collection is worth a look.
How to Lift Your Bulbs Safely
When the foliage has died back and the bulbs are dormant, it is time to get them out of the ground. You want to be as gentle as possible during this step. A damaged bulb is more susceptible to rot and disease during storage, so taking your time pays off.
It is best to use a garden fork rather than a sharp spade if you have one. A fork is less likely to slice through the bulbs as you work. Start by inserting the tool into the soil several inches away from the center of the clump. This gives you a wide berth so you don't accidentally strike the bulbs. Gently pry upward to loosen the soil and lift the entire mass of bulbs to the surface.
Once the bulbs are out of the ground, use your hands to shake off the large clumps of soil. You can gently pull apart the individual bulbs if they are part of a large cluster. You will often see smaller "offset" bulbs attached to the base of the larger mother bulb. These can be separated easily if they have their own skin and look independent. If they are still firmly attached, it is better to leave them together for another year.
Inspecting for Quality
As you clean the bulbs, take a moment to inspect each one. A healthy daffodil bulb should feel heavy and firm to the touch, much like a good-quality onion. If a bulb feels light, hollow, or "squishy," it is likely past its prime or has started to rot.
Look for any signs of mold, soft spots, or significant mechanical damage from your tools. It is always better to discard a questionable bulb now than to let it sit in storage where it could potentially spread rot to its healthy neighbors. We recommend only keeping the best, most robust bulbs to ensure a successful garden next spring.
- Firm bulbs: Keep these for replanting.
- Mushy or soft bulbs: Discard these immediately.
- Bulbs with mold: Discard to prevent spreading.
- Dried-out or "papery" hollow bulbs: These won't grow and can be tossed.
The Curing Process
"Curing" is just a fancy gardening term for letting the bulbs dry out properly before they go into long-term storage. This is a vital step because any moisture trapped against the bulb’s skin can lead to fungal growth.
Find a spot that is out of direct sunlight but has excellent air circulation. A shady porch, a garage workbench, or even a garden shed works well. Spread the bulbs out in a single layer on a flat surface. You can use a piece of cardboard, a window screen, or a wooden crate. Avoid stacking the bulbs on top of each other, as this restricts airflow.
Let the bulbs sit for about 2 to 7 days. During this time, any remaining soil will dry up and become easy to brush off. The outer skin of the bulb, known as the tunic, will become dry and papery. This skin acts as a protective layer for the soft tissue inside. Once the bulbs feel completely dry to the touch and the last bits of dirt fall away easily, they are ready for their summer home.
What to do next:
- Move bulbs to a shaded, breezy area immediately after digging.
- Spread them in a single layer to ensure every bulb gets air.
- Wait until the outer skin is dry and papery before moving to storage.
- Avoid using water to clean the bulbs; a dry brush is much safer.
Choosing the Right Storage Container
The most important rule for storing daffodil bulbs over the summer is to avoid plastic at all costs. Plastic bags or airtight containers trap moisture and heat, which is the perfect recipe for mold and rot. Your bulbs are living organisms, and even in their dormant state, they need to "breathe" a little bit.
Mesh bags are often the best choice. If you have saved bags from store-bought onions or oranges, these are perfect for storing bulbs. They allow air to circulate freely around every bulb. Another great option is an old pair of nylon stockings. You can drop a bulb in, tie a knot, and repeat the process until the stocking is full.
If you don't have mesh bags, paper bags are a good secondary option. Just make sure you don't overfill them, and perhaps poke a few holes in the sides of the bag to improve ventilation. Cardboard boxes or wooden fruit crates also work well, provided you don't stack the bulbs more than two layers deep. If you use a box, you can lightly nestle the bulbs in some dry peat moss or vermiculite to keep them from touching, though this isn't strictly necessary if the air is dry.
Finding the Ideal Storage Environment
Once your bulbs are packed, you need to find a place for them to rest until autumn. The goal is to mimic the cool, dark conditions they would naturally find deep underground, but without the moisture.
The ideal temperature for storing daffodil bulbs is between 60°F and 65°F. While they can handle slightly warmer temperatures, you should avoid areas that regularly exceed 70°F, as excessive heat can dry the bulbs out too much or damage the flower bud developing inside. Conversely, you don't want them to freeze, so an uninsulated shed in a very cold climate might not be the best spot if you are storing them into late fall.
A cool, dry basement is often the perfect location. If your basement is damp, a ventilated garage or a dark closet in the center of your house may be better. Make sure the area is dark, as light can sometimes trigger the bulbs to start sprouting prematurely.
Keep Away from Fruit
One common mistake is storing bulbs in a refrigerator or a pantry near ripening fruit. Many fruits, especially apples and pears, give off ethylene gas as they ripen. While this gas is harmless to humans, it is deadly to the flower buds inside your daffodil bulbs. Exposure to ethylene can cause the bulbs to become "blind," meaning they will grow leaves next year but will fail to produce any flowers. Keep your garden treasures far away from the kitchen. If you want to check your climate before replanting, use the Hardiness Zone Map.
Monitoring Your Bulbs During Summer
Even though your bulbs are tucked away, it is a good idea to check on them once or twice a month. This only takes a minute and can save your entire collection if a problem starts to develop.
When you check on them, look for any bulbs that might have started to soften or show signs of blue or gray mold. If you find one "bad apple," remove it immediately and discard it. Check the surrounding bulbs to make sure they are still dry and firm. If the bulbs feel slightly damp, you may need to move them to a spot with better air circulation or lower humidity.
Healthy bulbs should remain dormant and unchanged throughout the summer. If you see green tips starting to emerge, it is a sign that they are getting too much light or the temperature is fluctuating too much. Try to find a darker, more stable environment for them.
- Check once a month: Look for soft spots or mold.
- Assess humidity: If bulbs feel damp, increase airflow.
- Watch for sprouts: Keep them dark to prevent early growth.
- Sniff test: A healthy bulb smells like earth; a rotting bulb has a distinct, sour odor.
When to Replant
The storage period ends when the weather begins to cool down in the fall. In most regions, this is between September and November. The rule of thumb for replanting is to wait until the soil temperature has dropped, but the ground is still easy to work and hasn't frozen.
Ideally, you want to get your bulbs back into the ground about 2 to 4 weeks before the first hard frost. This gives them enough time to start developing a root system before the deep winter chill sets in. If you live in a very warm climate (Zone 8 or higher), you may need to keep your bulbs in storage a bit longer or even provide a "chilling period" in a refrigerator (away from fruit!) for 6–8 weeks before planting, as daffodils need cold temperatures to trigger their spring bloom.
When you are ready to plant, choose a sunny spot with well-draining soil. Our general rule at Longfield Gardens is to plant the bulb about twice as deep as the bulb is tall. For most daffodils, this means the base of the bulb should be about 6 inches deep. Space them 4 to 6 inches apart to give them room to grow and multiply over the coming years.
Managing Expectations
Gardening is a partnership with nature, and while we can provide the best conditions, things like unusual weather patterns or local soil variations will always play a role. When you store bulbs over the summer, keep in mind that they are living things. It is normal to lose a few bulbs to natural desiccation (drying out) during the storage process. This is why it is always a good idea to store a few more than you think you will need.
When you replant them in the fall, they may take a little time to settle back in. If you divided a very large, old clump, the smaller offset bulbs might spend their first year just growing foliage while they gather enough energy to bloom. This is perfectly normal and a sign that the plant is building its strength. The larger, mature bulbs should reward you with their classic blossoms right on schedule. For a broader fall shopping shortcut, the Daffodil Assorted Long-Blooming Yellow Collection offers a ready-made mix.
Key Takeaway Success comes from the basics: wait for the foliage to die naturally, dry the bulbs thoroughly, and store them in a cool, breathable spot.

FAQ
How long can I keep daffodil bulbs out of the ground?
Daffodil bulbs can stay out of the ground for the duration of their summer dormancy, typically from late June until the fall planting season in September or October. They should not be kept out of the soil for more than one full season, as they will eventually dry out and lose the energy needed to grow. It is best to get them back into the garden as soon as the autumn weather turns cool. If you want a simple planting reminder, the How Deep Should I Plant My Daffodil Bulbs? Planting Guide is a useful reference.
Do I need to wash the dirt off the bulbs with water?
No, it is much better to avoid using water to clean your bulbs. Introducing extra moisture right before storage can encourage rot and fungal growth. Instead, let the bulbs dry in a shaded area for a few days until the soil becomes crumbly. You can then easily brush off the excess dirt with your hands or a soft brush without risking the health of the bulb.
Can I store my daffodil bulbs in the refrigerator?
While a refrigerator provides a cool, dark environment, it is only recommended if you live in a very warm climate and need to "pre-chill" your bulbs to simulate winter. If you do use a refrigerator, you must be extremely careful to keep the bulbs away from any ripening fruit, like apples. These fruits release ethylene gas, which will destroy the flower bud inside the bulb, leading to no blooms in the spring. If you need a climate reference, check the Hardiness Zone Map first.
What should I do if my stored bulbs start to sprout in the summer?
If your bulbs start to grow green tips while in storage, they are likely getting too much light or the temperature is too high. Move them to a darker, cooler location immediately. If it is still mid-summer, do not plant them yet; wait until the soil cools in the fall. Early sprouting usually won't kill the bulb, but it does use up some of the energy that was meant for spring growth. For fall timing and shipping, review our Shipping Information.
