Introduction
There is nothing quite like the sight of the first daffodils poking through the soil to announce that spring has finally arrived. These cheerful, resilient flowers are a favorite for many of us because they are so reliable and easy to grow. Whether you are lifting your bulbs to thin out an overcrowded patch or moving them to a new part of your yard, the process is simple and rewarding.
At Longfield Gardens, we want to help you make the most of your garden by ensuring your bulbs stay healthy from the moment they finish blooming until they go back into the ground. Storing your bulbs correctly over the summer is an easy way to protect your investment and guarantee another spectacular show next spring. This guide will walk you through exactly how to dig, clean, and store your daffodil bulbs so they remain in peak condition.
By following a few basic steps, you can keep your bulbs safe and firm until the autumn planting season arrives.
Why You Might Choose to Store Daffodil Bulbs
Daffodils are famous for being "plant and forget" bulbs. In most cases, they are perfectly happy staying in the ground year-round. However, there are several practical reasons why you might want to lift them after they finish blooming and store them until fall.
Managing Overcrowded Clusters
Daffodils are excellent "naturalizers," which means they multiply on their own over time. While a large drift of flowers is beautiful, eventually the bulbs can become too crowded. When bulbs are packed too tightly together, they compete for nutrients and water. You might notice your once-vibrant patch is producing more leaves but fewer flowers. This is a clear sign that it is time to lift, divide, and store them for replanting with more space in the fall.

Protecting Bulbs from Summer Rot
Daffodils prefer to stay relatively dry during their dormant summer period. If your garden beds are equipped with automatic irrigation for summer annuals, or if you live in an area with very wet, humid summers, the bulbs may be at risk of rotting. Lifting them allows you to keep them in a controlled, dry environment until the cooler weather returns.

Redesigning Your Garden Space
Gardens are always evolving. You may decide to move your daffodils to a new flower bed or a different part of the yard. Digging them up in the summer gives you the freedom to rework your landscape without accidentally slicing into the bulbs while they are dormant and invisible underground.

Key Takeaway: While daffodils are hardy, lifting and storing them is the best way to manage overcrowding and protect bulbs from excessive summer moisture.
Timing Your Harvest Correctly
The most important rule for storing daffodil bulbs is to wait for the right time to dig them up. It can be tempting to clear away the fading foliage as soon as the flowers wither, but patience is a virtue in this case.
The Role of Foliage
After a daffodil finishes blooming, the leaves continue to work hard. Through the process of photosynthesis, the leaves gather energy from the sun and store it in the bulb. This energy is exactly what the bulb needs to develop next year's flower and survive the dormant season. If you cut the leaves back while they are still green, the bulb will be weaker and may not bloom the following spring.
Signs the Bulbs are Ready
You should wait until the foliage has turned completely yellow or brown and has begun to go limp. This usually happens about six to eight weeks after the flowers have finished. At this point, the leaves have finished their job, and the bulb has pulled in all the nutrients it can. The leaves will often pull away from the bulb with a very gentle tug once they are fully dry.
What to Do Next
- Allow the foliage to die back naturally.
- Avoid braiding or tying the leaves, as this reduces the surface area available for sunlight.
- Wait for a dry day to dig, as bulbs are easier to clean when the soil isn't muddy.
How to Dig and Handle Bulbs Gently
When it is time to lift the bulbs, your goal is to get them out of the ground without any nicks or bruises. Damaged bulbs are much more likely to develop rot or attract pests during storage.
Using the Right Tools
A garden fork is often better than a spade for this task. The tines of a fork can slide into the soil with less risk of slicing directly through a bulb. If you only have a spade, make sure to start your digging circle several inches away from the center of the plant to give the bulbs a wide berth.
Lifting the Clumps
Insert your tool into the soil at least six inches away from the base of the foliage. Gently pry upward to loosen the soil. You may need to do this at a few different points around the clump. Once the soil is loose, you can reach in and lift the entire cluster of bulbs out by hand.
Initial Cleaning
Once the bulbs are out of the ground, gently shake them to remove large clumps of dirt. Do not scrub the bulbs or use water to wash them. Moisture is the enemy of stored bulbs, so it is better to leave a little dry dust on them than to get them wet. If the soil is very damp, let the bulbs sit on the surface of the soil in the sun for an hour or two to dry out before moving them to your staging area.
The Curing Process
"Curing" is a professional-sounding term for a very simple step: letting the bulbs dry out completely before they go into long-term storage. This process toughens the outer skin of the bulb and helps prevent fungal issues.
Find a Shady, Airy Spot
Move your cleaned bulbs to a place that is out of direct sunlight but has excellent air circulation. A covered porch, a garage, or a garden shed works perfectly. Spread the bulbs out in a single layer. Do not stack them on top of each other, as this can trap moisture and lead to mold.
How Long to Cure
Bulbs typically need about one to two weeks to cure. You will know they are ready when the outer tunics (the papery skin) feel dry and crispy. Any remaining roots will also be dry and brittle.
Final Inspection
Before the bulbs go into storage, give them a quick health check.
- Feel the bulbs: They should be heavy and firm. Discard any that feel light, hollow, or squishy.
- Look for damage: If a bulb was accidentally sliced by the shovel, it is best to toss it.
- Check for pests: Look for any holes or signs of insect activity.
- Separate offsets: If small "baby" bulbs are loosely attached to the main bulb and fall off easily, you can store them separately. If they are firmly attached, leave them alone to avoid wounding the parent bulb.
Key Takeaway: Curing your bulbs in a single layer for 10-14 days is the most important step in preventing rot during the summer months.
Choosing the Best Storage Container
Once your bulbs are cured and cleaned, you need a home for them until fall. The golden rule for storage containers is that they must breathe. Never use plastic bags or airtight bins, as these will suffocate the bulbs and cause them to rot almost immediately.
Mesh Bags
Old onion bags or specialized nylon mesh garden bags are the gold standard for bulb storage. They allow air to flow around the bulbs from every angle. You can even hang the bags from rafters in a garage or basement to maximize airflow and keep them away from rodents.
Paper Bags
If you don't have mesh bags, plain brown paper lunch bags or grocery bags work well. They are breathable and keep the bulbs dark. To improve airflow, you can use a hole punch to make several small holes in the sides of the bag. Avoid overfilling the bags; a few layers of bulbs are fine, but a giant sack of bulbs can become heavy and restrict air at the bottom.
Cardboard Boxes or Trays
Low-profile cardboard boxes or wooden crates are also excellent options. Line the bottom with a layer of newspaper and spread the bulbs out. If you have a lot of bulbs, you can place a layer of dry peat moss or sawdust between them to keep them from touching, though this isn't strictly necessary if your storage area is dry.
What to Do Next
- Label your containers with the variety and color.
- Keep different varieties in separate bags to avoid confusion in the fall.
- Double-check that no plastic is touching the bulbs.
Creating the Ideal Storage Environment
Where you put your bulbs is just as important as what you put them in. Daffodil bulbs are living things that are simply "sleeping," and they need specific conditions to stay healthy during their nap.
Temperature Control
The ideal temperature for storing daffodil bulbs is between 60°F and 70°F. Most basements, crawl spaces, or insulated garages stay within this range naturally during the summer. Avoid areas that get excessively hot, like an attic or a garden shed in full sun. High heat can dry out the bulbs so much that they lose the energy they need to grow.
Humidity and Moisture
A dry environment is essential. While a little bit of humidity is fine, the area should not be damp or musty. If you are storing bulbs in a basement, keep them away from the floor or walls where moisture might seep in. Hanging them or placing them on a shelf is always a safer bet.
Darkness
Bulbs should be stored in the dark. Sunlight can trigger them to "wake up" too early or may cause them to dry out too quickly. Most storage containers like paper bags or boxes naturally provide darkness, but it’s still best to keep them away from windows.
Airflow
Do not tuck your bulb bags into a corner behind heavy boxes. They need room for air to circulate. If the air becomes stagnant, the risk of fungal growth increases. If you are storing them in a closet or cupboard, leave the door cracked occasionally to let fresh air in.
A Note on Ethylene Gas and Refrigeration
You might have heard that some gardeners store their bulbs in the refrigerator. While this is sometimes done to "force" bulbs for early indoor blooming, it is generally not recommended for standard summer storage, especially if you have food in the fridge.
The Danger of Fruit
Many fruits, particularly apples and pears, release ethylene gas as they ripen. This gas is harmless to humans but can be deadly to flower bulbs. Exposure to ethylene can destroy the flower bud inside the bulb, meaning your daffodils will grow leaves next year but no flowers.
Best Practice
Unless you have a dedicated "bulb-only" refrigerator set to a consistent temperature, it is much safer to store your daffodils in a cool basement or garage. They do not need artificial cooling during the summer months; they simply need to be kept away from extreme heat.
Maintaining Your Bulbs Over Summer
Storing your bulbs isn't a "set it and forget it" task. It only takes a minute or two once a month to check on them, and this small effort can save your entire collection if a problem arises.
Monthly Check-ins
Once every four weeks, take a quick peek at your storage bags. Look for any bulbs that appear to be shriveling excessively or showing signs of mold. If you find one bulb that has gone soft or fuzzy, remove it immediately and throw it away. This prevents the issue from spreading to the healthy bulbs nearby.
Signs of Trouble
- Soft or Mushy: This is a sign of rot. Remove the bulb immediately.
- Blue or Green Mold: This usually indicates that the storage area is too damp or there isn't enough airflow. Move the bulbs to a drier spot.
- Extremely Light Weight: If a bulb feels like a feather, it has dried out completely and is likely dead.
What to Do Next
- Set a calendar reminder to check your bulbs on the first of each month.
- Adjust your storage location if you notice any dampness after heavy summer rains.
- Keep the storage area clean and free of clutter to discourage pests.
Preparing for Fall Replanting
As the weather begins to cool and the kids head back to school, it's time to start thinking about getting those daffodils back into the ground.
Timing the Replant
Daffodils should be replanted in the fall when the soil temperature has dropped but before the ground freezes. In most parts of the United States, this is between late September and November. Our Shipping Information page explains how we time orders by zone, so that is a great time to check your own stored stash. (longfield-gardens.com)
Selecting the Right Spot
When you bring your bulbs out of storage, give them one final inspection. They should still be firm and heavy. Choose a planting site that offers:
- Full to Partial Sun: At least 6 hours of light is best.
- Good Drainage: Daffodils hate "wet feet," so avoid low spots where water puddles.
- Space to Grow: Since you likely lifted them because of overcrowding, make sure to give them enough room this time—about 3 to 6 inches apart.
If you want to compare bloom times and flower styles before replanting, the Planning Guide for Daffodils is a good companion resource. (longfield-gardens.com)
Planting Depth
The general rule of thumb for daffodils is to plant them three times as deep as the bulb is tall. For most standard daffodils, this means the base of the bulb should be about 6 inches deep. Small miniature varieties only need to be about 3 or 4 inches deep. Always plant with the pointed end facing up.

Dealing with Pests and Safety
While we love daffodils, they do come with a few safety considerations for the home gardener.
Toxicity
Daffodil bulbs contain lycorine, an alkaloid that is toxic if ingested. This is actually a benefit in the garden because it makes them naturally resistant to deer, rabbits, and squirrels. However, it is important to keep your stored bulbs out of reach of curious pets and children.
Skin Irritation
Some people experience a mild skin itch or rash after handling a large number of daffodil bulbs, often called "lily rash." This is caused by calcium oxalate crystals in the bulb's sap. If you have sensitive skin, wearing gardening gloves while digging, cleaning, and replanting is an easy way to stay comfortable.
Rodent Protection
Even though squirrels don't usually eat daffodil bulbs, they are famous for digging them up just to see what they are. When you replant in the fall, make sure to firm the soil down well. Some gardeners also place a piece of chicken wire over the planting area and cover it with mulch to discourage digging.

Proper storage protects the energy stored within the bulb, ensuring that your spring garden returns even stronger and more beautiful than the year before.
FAQ
Can I store daffodil bulbs in the refrigerator?
It is generally not recommended to store daffodil bulbs in a standard kitchen refrigerator. Most fruits release ethylene gas which can destroy the flower bud inside the bulb. A cool, dry basement or garage between 60-70°F is a much safer environment for summer storage.
How long can daffodil bulbs stay out of the ground?
Daffodil bulbs can stay out of the ground for the duration of their dormant season, which is typically from early summer until late fall. While they can technically survive a bit longer, they must be replanted in the fall so they can grow roots before the ground freezes. They will not survive in a bag until the following spring.
Do I need to wash the dirt off the bulbs before storing them?
No, you should never wash daffodil bulbs with water before storage. Moisture can lead to rot and fungal diseases. Instead, let the bulbs dry for a few hours in the shade and then gently brush off any loose soil with your hands or a soft brush.
What should I do if my stored bulbs start to sprout in the bag?
If you see green tips emerging, it is a sign that the bulbs are being kept too warm or are getting too much light. Check your storage temperature and move them to a cooler, darker spot. If it is close to fall, go ahead and plant them in the ground as soon as possible, as they are ready to grow.
