Introduction
There is nothing quite like the sight of the first daffodil blossoms emerging after a long winter. Those bright yellows, soft whites, and peachy oranges are a signal that the garden is coming back to life. While many gardeners choose to leave their bulbs in the ground year-round, there are several reasons why you might want to lift and store them during the warmer months. Whether you are reorganizing your flower beds, dividing crowded clumps to encourage better blooming, or making room for summer annuals, knowing the right way to handle these spring favorites is key to a beautiful display next year.
At Longfield Gardens, we believe that gardening should be a rewarding and straightforward experience. Storing bulbs doesn't have to be a complicated science; it is simply about mimicking the plant’s natural cycle of rest. By following a few basic steps, you can ensure your bulbs stay healthy, firm, and ready to burst into bloom once the autumn planting season arrives. This guide will walk you through the process of harvesting, curing, and storing your daffodils so you can enjoy their cheerful faces season after season.
Learning how do you store daffodil bulbs over the summer is an excellent way to take control of your garden layout and maintain the health of your prized daffodils.
Why You Might Choose to Lift Your Bulbs
Daffodils are remarkably hardy and can often stay in the same spot for many years. However, "lifting" (the gardening term for digging up) and storing them over the summer can be a smart move for several reasons. The most common reason is overcrowding. Over time, a single daffodil bulb will produce "offsets" or daughter bulbs. Eventually, the clump becomes so dense that the plants compete for nutrients and space. If you notice your daffodils are producing lots of green leaves but fewer or smaller flowers, it is likely time to lift, divide, and store them.
Another reason to store bulbs is to protect them from "wet feet." While daffodils are tough, they do not like to sit in soggy soil during their dormant summer period. If your garden beds are heavily irrigated for summer vegetables or annuals, the extra water can cause dormant bulbs to rot. By lifting them, you keep them in a controlled, dry environment. Additionally, if you are planning a major landscaping change, storing the bulbs allows you to save your favorites—like the classic Daffodil Trumpet Dutch Master or the fragrant Daffodil Trumpet Mount Hood—and move them to a new location in the fall.
Timing Your Harvest: The Golden Rule of Foliage
The most important rule of storing daffodil bulbs is one that requires a little bit of patience: you must wait for the foliage to die back naturally. After the flowers fade, the green leaves remain. It might be tempting to cut these back to keep the garden looking tidy, but those leaves are hard at work. They act like solar panels, absorbing sunlight and converting it into energy. This energy is sent down into the bulb to "recharge" it for next year’s bloom.
Wait until the leaves have turned yellow or brown and have started to collapse toward the ground. This usually happens about six to eight weeks after the flowering has finished. At this stage, the bulb has finished its work and is entering its dormant phase. If you cut the leaves while they are still green, the bulb will be "blind" next year, meaning it may produce leaves but will lack the energy to create a flower.
Key Takeaway: Never cut or tie up green daffodil foliage. Let it turn completely yellow or brown before lifting the bulbs to ensure they have enough energy stored for next year's blossoms.
How to Dig Your Bulbs Without Damage
When the foliage is ready, it is time to get the bulbs out of the ground. It is best to choose a day when the soil is relatively dry, as this makes it much easier to shake off excess dirt. Using a garden fork is often better than a spade, as the tines are less likely to slice through a bulb if you accidentally strike one.
Start by inserting your tool into the soil several inches away from the center of the clump. This gives you a wide berth to avoid damaging the bulbs or their root systems. Gently pry upward to loosen the soil. Once the soil is loose, you can often lift the entire clump by the base of the dried foliage. If the foliage breaks away, simply reach into the loose soil and gather the bulbs by hand.
Once the bulbs are out, give them a gentle shake to remove large clumps of soil. Do not wash them with water; moisture is the enemy during the storage process. Use your fingers to brush away any loose dirt. At this stage, you may notice that the bulbs naturally pull apart into smaller individual bulbs. This is the perfect time to divide them. If they are still firmly attached, leave them be; forcing them apart can create wounds that lead to rot.
The Curing Process: Preparing for Storage
"Curing" is just a fancy word for letting the bulbs dry out. This is a vital step because it toughens the outer skin (the tunic) and ensures that no moisture is trapped inside, which could lead to mold. After you have dug and cleaned the bulbs, find a shady, well-ventilated spot to let them rest. A porch, a garage workbench, or a garden shed works perfectly.
Lay the bulbs out in a single layer. Do not stack them, as this prevents air from reaching all sides of the bulb. You can place them on a tray, a piece of cardboard, or even a screen. Avoid placing them in direct sunlight, as this can "cook" the bulbs or cause them to dry out too quickly. Let them cure for two to three days. You will know they are ready when the outer skin feels papery and dry, and any remaining bits of soil fall off easily with a light touch.
Selecting the Best Storage Location
The environment where your bulbs spend their summer will determine how well they perform in the spring. You are looking for a "Goldilocks" zone: not too hot, not too cold, and definitely not damp. The ideal temperature for storing daffodil bulbs is between 60°F and 70°F. This is roughly room temperature for most homes, though a slightly cooler basement or garage is often the most practical spot.
Humidity is another factor to consider. A damp basement can encourage fungus, while a bone-dry attic might cause the bulbs to shrivel. A standard garage or a well-ventilated garden shed usually provides the right balance. Keep the bulbs away from ripening fruit, such as apples or pears. These fruits release ethylene gas, which can actually kill the flower bud inside the daffodil bulb.

Choosing the Right Storage Containers
How you package your bulbs is just as important as where you put them. The most critical rule is to avoid plastic. Plastic bags or airtight containers trap moisture and heat, which will quickly rot your bulbs. Instead, use materials that allow the bulbs to "breathe."
- Mesh Bags: Old onion or citrus bags from the grocery store are perfect for bulb storage. They provide maximum airflow and allow you to hang the bulbs from a hook, keeping them away from rodents.
- Paper Bags: These are a great option if you have many different varieties to keep separate. Just be sure to poke a few holes in the sides to encourage air circulation.
- Cardboard Boxes or Crates: A shallow cardboard box lined with newspaper works well. You can also use wooden crates or plastic nursery flats.
- Egg Cartons: For smaller bulbs like the miniature Tete a Tete variety, paper egg cartons provide individual "rooms" that keep the bulbs from touching.
If you are storing multiple varieties, we recommend labeling your containers immediately. It is surprisingly easy to forget which bulbs are the tall 'King Alfred' types and which are the delicate 'Ice Follies' once they are all out of the ground!
What to Do Next: A Storage Checklist
Before you tuck your bulbs away for the summer, run through this quick checklist to ensure they are set up for success:
- Inspect every bulb: Toss out any that feel soft, mushy, or exceptionally light. A healthy bulb should feel heavy for its size, like a firm onion.
- Remove old roots: Once the bulbs are dry, you can gently trim away the long, withered roots if they are in the way.
- Check for ventilation: Ensure your storage container is not crowded. Space the bulbs out so they aren't touching if possible.
- Set a reminder: Mark your calendar for late September or October so you don't forget to get your bulbs back into the ground!

Monitoring Your Bulbs During the Summer
Storing bulbs is mostly a "set it and forget it" task, but a quick check once a month is a good habit. Occasionally, a bulb that looked healthy during harvest might develop rot or mold during the summer. By checking on them, you can remove any "bad apples" before the problem spreads to the rest of the batch.
If you notice a small amount of surface mold, it is usually not a cause for alarm. Simply wipe it off and ensure the bulbs have better airflow. However, if a bulb becomes soft or develops a foul odor, discard it immediately. This occasional monitoring ensures that when autumn arrives, you are planting only the strongest, healthiest bulbs.

When to Replant Your Stored Bulbs
The summer storage period ends when the soil begins to cool down in the fall. For most of the United States, this is between September and November. Ideally, you want to plant your daffodils about two to four weeks before the ground freezes. This gives the bulbs enough time to grow new roots and settle in before the deep winter chill arrives.
When you bring your bulbs out of storage, they should still feel firm. If some have started to sprout small green tips, don't worry—just get them into the ground as soon as possible. Plant them about 6 inches deep (or three times the height of the bulb) with the pointy end facing up. Even if you aren't sure which end is the top, the bulb is smart enough to find its way toward the light, though planting it correctly helps it get a faster start.

FAQ
Can I store daffodil bulbs in the refrigerator?
It is generally not recommended to store daffodil bulbs in a refrigerator that also contains food. Many fruits and vegetables release ethylene gas, which can damage the developing flower bud inside the bulb. Additionally, a refrigerator is often too cold and damp for long-term summer storage; a cool garage or basement is a much better environment.
What happens if I cut the green leaves off early?
If you cut the foliage while it is still green, you are essentially "starving" the bulb. The leaves are the only way the bulb can gather energy for the following year. Cutting them early often results in "blindness," where the bulb survives and grows leaves the next year but fails to produce any flowers.
Do I need to treat my stored bulbs with fungicide?
For most home gardeners, a fungicide is not necessary if the bulbs are properly cured and stored in a dry, well-ventilated area. If you live in an extremely humid climate and have had issues with rot in the past, you can lightly dust the bulbs with a garden-safe sulfur powder before putting them into storage.
How long can daffodil bulbs stay out of the ground?
Daffodil bulbs are meant to be replanted every year. While they can survive for several months in storage over the summer, they should always be returned to the soil by late fall. If you miss the fall planting window, the bulbs will likely dry out or lose too much energy to survive until the following year.
