Introduction
There is nothing quite like the crisp air of autumn to get a gardener excited about the coming spring. Tucking dormant bulbs into the soil feels like a promise of future color, and at Longfield Gardens, we share that anticipation with you. However, it can be a bit surprising to head out to your garden the morning after planting only to find small holes in the mulch or bulbs sitting on top of the soil.
If you have ever wondered what is digging up my daffodil bulbs, you are certainly not alone. While it might feel like a setback, identifying the visitor is the first step toward a beautiful, undisturbed spring display. This guide will help you identify the common backyard animals responsible for this behavior and provide simple, effective ways to keep your garden peaceful. By understanding why animals are attracted to your planting sites, you can protect your bulbs and ensure a successful bloom.
The Mystery of the Dug-Up Bulb
Daffodils are unique in the world of spring-flowering bulbs because they have a built-in defense mechanism. Unlike tulips or lilies, which are often viewed as a delicious snack by wildlife, daffodils contain a bitter-tasting alkaloid called lycorine. This substance makes the bulbs toxic and unappealing to almost every common garden pest, including deer and rabbits.
If daffodils are unpalatable, why do they get dug up? Most of the time, the digging is accidental or a case of "mistaken identity." Animals are often looking for something else entirely, and your freshly tilled soil provides an easy place for them to search. Understanding this distinction helps you choose the right approach to keep your garden beds intact.
Why Animals Target New Planting Sites
When we plant bulbs, we naturally disturb the soil. This creates a few signals that attract curious wildlife:
- Fresh Scents: The smell of freshly turned earth and the papery skins of the bulbs can signal to an animal that something has been buried there.
- Soft Soil: Loose, aerated soil is much easier to dig in than the surrounding hard-packed earth.
- Searching for Snacks: Many animals bury their own food (like acorns) in soft soil and may dig in your garden bed assuming they—or a competitor—left a treat there.
Identifying the Suspects
To solve the problem, we first need to look at the "clues" left behind in the garden. Different animals have distinct digging styles and schedules.
Squirrels: The Curious Gardeners
Squirrels are the most frequent culprits. They are active during the day and have a natural instinct to bury nuts for the winter. When they see you digging in the garden, they often investigate the area once you go inside.
A squirrel typically leaves a small, shallow hole about the size of a golf ball. They may pull a daffodil bulb out of the ground, take one bite, realize it tastes terrible, and leave it right there on the surface. If you find your bulbs scattered around the planting hole but not actually eaten, a squirrel is likely the visitor.
Skunks and Raccoons: The Grub Hunters
Skunks and raccoons are nocturnal, so you will likely see the results of their work in the morning. They aren't interested in the bulbs themselves. Instead, they are looking for grubs and worms that live in the soil.
Raccoons use their paws like hands to flip over chunks of mulch or sod. Skunks tend to leave "cone-shaped" holes. If your garden looks like it has been lightly rototilled or if there are patches of soil peeled back, these animals are likely looking for insects. The soft soil you created while planting makes it much easier for them to find their breakfast.
Voles and Chipmunks: The Tunnelers
Voles are small rodents that create tunnels just beneath the surface of the soil. While they love to eat tulip bulbs, they usually avoid eating daffodils. However, their tunneling can dislodge daffodil bulbs or push them toward the surface.
Chipmunks also dig small entrance and exit holes for their burrows. If you see a perfectly round hole about two inches wide with no mound of dirt next to it, a chipmunk might be living nearby. Like squirrels, they may dig up a bulb out of curiosity or to clear a path for a tunnel.
Domestic Pets
Sometimes the visitor isn't a wild animal at all. Dogs, especially those that enjoy digging, may be attracted to the scent of organic fertilizers like bone meal or blood meal often used during planting. If you have recently amended your soil and find large, messy holes, your neighborhood canine friend might be the cause.
Key Takeaway: If your daffodil bulbs are sitting on top of the soil but appear uneaten, the animal was likely investigating the soft soil or searching for other food rather than trying to eat the bulb.
Simple Strategies to Stop the Digging
Once you know who is visiting your garden, you can take a few easy steps to encourage them to move along. You do not need complex equipment or harsh chemicals to keep your bulbs safe.
Clean Up the Planting Site
This is the simplest and most effective tip. When you plant bulbs, the papery outer layers (called tunics) often fall off. These skins carry the scent of the bulb. If you leave them scattered on top of the soil, it acts like a "Welcome" sign for squirrels.
- Always carry a small bucket or bag with you while planting.
- Collect all the loose skins and discarded bulb bits.
- Dispose of them in the trash or a closed compost bin away from the garden bed.
The Power of Planting Depth
Getting the depth right is a quiet winner in garden success. As a general rule, daffodils should be planted about three times as deep as the bulb is tall. For a standard daffodil bulb, this means the base of the bulb should be 6 to 8 inches deep.
Deep planting makes it much harder for small animals like squirrels and chipmunks to reach the bulb. It also helps the bulb stay at a more consistent temperature throughout the winter. If you plant too shallowly, the bulbs are much more likely to be accidentally unearthed.
Use Physical Barriers
If you have very persistent squirrels or raccoons, a physical barrier is the best way to ensure your bulbs stay put until the ground freezes.
- Chicken Wire or Hardware Cloth: After planting your bulbs and leveling the soil, lay a piece of poultry netting (chicken wire) or 1/2-inch hardware cloth over the surface of the bed.
- Secure the Edges: Use landscape staples to pin the wire flat against the soil.
- Cover with Mulch: Hide the wire with a two-inch layer of mulch or shredded leaves.
- Wait for the Freeze: Once the ground freezes solid, animals can no longer dig, and you can choose to remove the wire or leave it. Most bulbs, including daffodils, can grow right through the gaps in chicken wire in the spring.
Avoid Smelly Fertilizers
Many gardeners like to add bone meal to the planting hole. While bone meal is a traditional source of phosphorus, its scent is highly attractive to dogs, raccoons, and skunks.
- If you choose to use bone meal, mix it thoroughly into the soil at the bottom of the hole so the scent is buried deep.
- Consider using a synthetic bulb fertilizer instead, as these generally do not have an animal-attracting scent.
Mulch and Camouflage
Animals are visually attracted to patches of fresh, dark soil. By camouflaging the area, you make it less obvious that something has changed.
- Cover the entire garden bed with a uniform layer of mulch, such as wood chips or pine needles.
- Spread some dry leaves over the area to make it look like the rest of the yard.
- Water the area well after planting. This helps "settle" the soil and dissipates the scent of the fresh digging.
What to do next:
- Clear all bulb skins and debris from the soil surface.
- Check that your bulbs are at least 6 inches deep.
- Apply a fresh layer of mulch to disguise the disturbed earth.
- If digging persists, lay chicken wire over the area for the first two weeks.
Natural Repellents and Scents
If physical barriers aren't an option, you can use scent to your advantage. Because animals have a much stronger sense of smell than humans, certain odors can make your garden bed feel "unpleasant" or "unsafe" to them.
Spicy and Pungent Deterrents
Squirrels and rodents generally dislike the smell and taste of capsaicin (the heat in hot peppers).
- Red Pepper Flakes: You can sprinkle crushed red pepper flakes into the planting hole or on the surface of the soil.
- Garlic: Some gardeners find success burying a few cloves of garlic or using a garlic-based spray around the perimeter of the bed.
- Castor Oil Sprays: These are often used to deter voles and moles. The scent is unappealing to them and encourages them to tunnel elsewhere.
Predator Scents
Commercial repellents often use the scent of predator urine (like fox or coyote) to trigger a flight response in small prey animals.
- Follow the label instructions carefully.
- Remember that these often need to be reapplied after heavy rain.
When Humans are the Ones Digging
Sometimes the question of "what is digging up my daffodil bulbs" comes from the gardener themselves. There are times when it is actually beneficial for us to dig up the bulbs. If you aren't seeing signs of pests, but your daffodils aren't blooming well, it might be time for a little maintenance.
Dividing Overcrowded Clumps
Daffodils are wonderful because they "naturalize," meaning they multiply over time. However, after five to seven years, a single bulb can turn into a dense clump of twenty bulbs. When they become too crowded, they compete for nutrients and water, which results in lots of green leaves but very few flowers.
The best time to dig and divide your own daffodils is in late spring or early summer, just as the leaves are beginning to turn yellow and die back. This allows you to see exactly where the bulbs are located.
- Lift Gently: Use a garden fork to lift the entire clump out of the soil.
- Separate by Hand: Gently pull the bulbs apart. You will notice smaller "offset" bulbs attached to the main bulb.
- Replant or Store: You can replant them immediately in a new location or store them in a cool, dry place until fall.
Moving Bulbs for Garden Renovations
If you are redesigning a bed or moving to a new home, you can dig up your favorite varieties to take with you. While fall is the traditional time to move dormant bulbs, daffodils are quite hardy. Even if you have to move them "in the green" (while they still have leaves), they will usually survive if you keep the roots moist and replant them promptly.
Handling and Safety
It is important to remember that all parts of the daffodil are toxic if eaten. This is why they are so deer-resistant! However, the sap can also cause skin irritation for some people, a condition sometimes called "lily rash."
- Wear gloves when handling large quantities of bulbs.
- Always wash your hands after planting.
- Keep bulbs stored safely away from curious pets or children.
Growing Success with Longfield Gardens
At Longfield Gardens, we want every gardener to experience the simple joy of a blooming spring garden. Whether you are planting a few dozen 'Dutch Master' daffodils or a sweeping drift of miniature 'Tête-à-Tête,' getting the basics right is the key to success.
Wildlife is a natural part of any healthy garden ecosystem. While it can be a bit startling to see a hole in your flower bed, most digging is temporary curiosity. Once the soil settles and the weather cools, the animals will move on to other food sources. By using a few simple physical barriers and keeping your planting site clean, you can protect your investment and look forward to a vibrant, colorful spring.
Summary of Best Practices
- Right Plant, Right Place: Choose daffodils for areas with high deer or rabbit pressure.
- Depth is Key: Plant at least 6 inches deep to discourage squirrels.
- Cleanliness Matters: Remove all papery skins from the garden surface.
- Barrier Protection: Use chicken wire if you have persistent digging issues.
- Be Patient: If a bulb is dug up, just tuck it back in. Most will still bloom beautifully.

Conclusion
Finding your daffodil bulbs unearthed can be a bit of a surprise, but it is rarely a sign of a major problem. Because daffodils are naturally resistant to being eaten, the digging is almost always a result of a curious squirrel or a nocturnal animal looking for grubs. By clearing away debris, planting at the correct depth, and using simple barriers like chicken wire, you can easily protect your spring display.
- Identify the culprit by the shape and timing of the holes.
- Use physical barriers like mesh for the first few weeks after planting.
- Always plant at least 6 inches deep to keep bulbs out of reach.
- Remember that daffodils are toxic to pests, which is why they are a top choice for trouble-free gardening.

FAQ
Do squirrels eat daffodil bulbs?
No, squirrels generally do not eat daffodil bulbs because they contain lycorine, a bitter and toxic substance. However, squirrels are very curious and will often dig them up to "test" them or because they are attracted to the soft, freshly disturbed soil. If they pull a bulb out, they usually leave it on the surface once they realize it is not a nut.
How deep should I plant daffodils to stop animals from digging them?
You should plant daffodil bulbs so that the base of the bulb is 6 to 8 inches deep (or about three times the height of the bulb). Planting at this depth makes it much harder for squirrels and chipmunks to reach the bulbs. It also provides a more stable environment for the bulb to grow throughout the winter.
What can I put over my bulbs to stop animals from digging?
The most effective physical barrier is a layer of chicken wire or 1/2-inch hardware cloth. Lay the wire flat over the soil surface after planting and secure it with landscape staples. You can cover the wire with a layer of mulch to hide it; the daffodils will grow right through the holes in the spring.
Why are my daffodil bulbs sitting on top of the soil?
If you find bulbs on the surface, it is usually due to one of two things: an animal dug them up and left them there, or the "freeze-thaw" cycle of the soil pushed them up. This often happens if the bulbs were planted too shallowly. Simply dig a hole to the correct depth and replant them as soon as you find them.
