Introduction
Few sights in the garden are as rewarding as the first tulip blooms of spring. These elegant flowers represent the true start of the growing season, bringing vibrant colors and graceful shapes to your flower beds. Planning your spring display is an exciting process, and at Longfield Gardens, we want to ensure your gardening experience is successful from the very first day you head out with a trowel.
While you may worry about local wildlife discovering your freshly planted treasures, protecting your garden is much simpler than you might think. Squirrels are curious creatures, but they are also quite predictable. By understanding their habits and making a few small adjustments to your planting routine, you can keep your garden safe.
This guide will walk you through practical, time-tested methods to protect your tulip bulbs from the moment they go into the ground until they bloom in the spring. We will cover physical barriers, scent-based deterrents, and the benefit of choosing the right companion plants. With these straightforward steps, you can feel confident that your spring garden will be full of the beautiful tulips you envision.
Understanding Why Squirrels Dig
To protect your garden, it helps to understand why squirrels are interested in your flower beds in the first place. Many people assume squirrels are specifically hunting for tulip bulbs to eat. While they may nibble on a bulb if they find one, their primary motivation is actually a bit different.
Squirrels are instinctively driven to find buried food sources, especially in the fall as they prepare for winter. When they see freshly turned soil, their natural instinct tells them that another animal has recently buried a cache of nuts or seeds there. To a squirrel, a tidy circle of loose earth is a "treasure map" leading to a potential meal.
They dig into the loose soil to investigate. Once they find your tulip bulb, they might take a test bite. If they decide they don't like it, they often leave the bulb on the surface of the soil and move on to the next spot. By understanding that squirrels are attracted to the act of digging itself, we can use strategies that hide our work and make the area less appealing to them.
The Power of Planting Depth
One of the easiest ways to protect your bulbs is to get the planting depth exactly right. Most squirrels are "surface diggers." They generally look for items buried just an inch or two below the soil surface. If your bulbs are nestled safely deep in the ground, they are much harder for a squirrel to accidentally discover.
For standard-sized tulips, we recommend planting at a depth of 6 to 8 inches. This measurement is taken from the bottom of the bulb to the soil surface. Planting at this depth provides several benefits:
- Temperature Stability: The soil temperature stays more consistent deep underground, which helps the bulb develop a strong root system during the winter.
- Protection from Paws: A squirrel is unlikely to dig a 6-inch hole just to see what is there. They prefer easy targets closer to the surface.
- Stem Support: Deeper planting provides a sturdy foundation for the tall stems of varieties like Darwin Hybrids or Triumph tulips.
When you finish planting, make sure to firm the soil down gently with your hands or the back of a shovel. This removes large air pockets and makes the soil feel more like the undisturbed earth around it.
Installing Physical Barriers
If you have a very active squirrel population, a physical barrier is the most reliable way to keep your bulbs safe. These barriers create a "shield" that allows the tulip stems to grow through while keeping paws away from the bulbs.
Using Chicken Wire
Chicken wire is a classic gardening tool for a reason. It is flexible, inexpensive, and very effective. You can use it in two different ways depending on your preference.
The first method is to lay the chicken wire directly over the bulbs before you fill the hole back in with soil. Place your bulbs at the correct depth, lay a piece of chicken wire over them, and then cover everything with soil. The tulip shoots will easily find their way through the one-inch holes in the wire, but a squirrel will find it impossible to dig down to the bulb.
The second method is to lay the wire on top of the soil surface after you have finished planting. You can secure the edges with landscape staples or heavy rocks. This prevents squirrels from even starting to dig. Once the ground freezes solid in the winter, you can remove the wire if you prefer, or leave it in place until the green shoots appear in the spring.
Hardware Cloth and Bulb Cages
Hardware cloth is a sturdier version of chicken wire with smaller, square openings. It is excellent for protecting small groups of bulbs or creating "bulb cages." A bulb cage is essentially a box made of wire mesh that completely surrounds the bulbs.
If you have issues with burrowing animals like voles or gophers, a full cage is a great solution. For squirrels, simply covering the top of the planting area is usually enough. Just ensure the mesh size is at least a half-inch wide so the tulip stems can grow through without being constricted.
Repurposing Window Screens
If you have old metal window screens, they can be repurposed as temporary covers for your bulb beds. Lay the screens over your freshly planted area and weigh them down with bricks. Because screens are permeable, rain and air can still reach the soil. This is a great "no-cost" way to protect a flat flower bed during the critical weeks following autumn planting.
What to do next:
- Measure your planting area to see how much chicken wire you need.
- Check that your wire mesh holes are at least a half-inch to one inch wide.
- Secure the edges of your barriers so curious paws can't lift them.
Camouflaging the Planting Site
Since squirrels are attracted to the sight and scent of freshly dug soil, camouflaging your work is a highly effective tactic. If the squirrel doesn't realize you were ever there, they won't be tempted to investigate.
Cleaning Up Scent Traces
Tulip bulbs have a faint scent, and the papery outer skin—known as the "tunic"—can fall off during planting. If these pieces are left sitting on top of the soil, they act like a signpost for squirrels.
Always pick up any stray bulb skins or damaged bulb pieces before you leave the garden. It is also a good idea to avoid using bone meal as a fertilizer if squirrels are a problem. While bone meal is a traditional bulb fertilizer, its strong scent can actually attract curious animals to your planting site. Instead, we recommend using a balanced, slow-release fertilizer or a layer of finished compost.
Using Mulch and Leaves
Once you have filled in your planting hole and firmed the soil, cover the area immediately. Use a layer of shredded bark mulch, wood chips, or even fallen autumn leaves. This layer of organic matter serves two purposes. First, it hides the visual evidence of your digging. Second, it helps regulate soil moisture and temperature, which is great for the health of your bulbs.
If you are planting in a lawn or a naturalized area, try to replace the sod or groundcover as neatly as possible. The goal is to make the ground look like it hasn't been touched in years.
Planting Through Groundcovers
Another clever trick is to plant your tulips underneath an existing groundcover. Low-growing plants like ivy, vinca minor, or creeping thyme provide a natural root barrier. Squirrels are generally reluctant to dig through a thick mat of established roots and stems. Simply tuck your bulbs into the soil between the existing plants. The tulips will pop up through the greenery in the spring, creating a beautiful layered look.
Strategic Interplanting with "Distasteful" Bulbs
Nature provides its own set of deterrents. Some spring-blooming bulbs contain natural compounds that taste bitter or smell unappealing to squirrels and other wildlife. By mixing these bulbs in with your tulips, you create a "shield" that protects the entire bed.
The Power of Alliums
Alliums are members of the onion family. While we love the ornamental beauty of their globe-shaped flower heads, squirrels are not fans of their onion-like scent. At Longfield Gardens, we offer many varieties of Alliums that pair beautifully with tulips.
Try planting a border of Allium Giant Gladiator around your tulip patch. If a squirrel starts to dig and encounters the scent of an Allium Aflatunense Purple Sensation, they are likely to move on to a different part of the yard. (Note: We do not ship Allium bulbs to Idaho due to state agricultural restrictions).
Daffodils: The Ultimate Deterrent
Daffodils (Narcissus) are perhaps the most squirrel-resistant bulbs you can grow. They contain a bitter substance called lycorine, which most animals find completely unpalatable. Squirrels almost never bother daffodils.
Interplanting tulips and daffodils is one of the smartest moves a gardener can make. You can mix them together in the same hole or plant them in alternating rows. This technique not only protects your tulips but also extends your blooming season, as different varieties will flower at different times. Classic yellow Trumpet daffodils or fragrant Jonquilla varieties are excellent companions for your favorite tulips.
Other Protective Companions
Hyacinths and Fritillaria Rubra Maxima are also excellent choices for a squirrel-resistant garden. Hyacinths have a very strong fragrance that many humans love, but squirrels often find it overwhelming. Fritillaria, particularly the large Crown Imperial (Fritillaria imperialis), has a distinct "skunky" odor that acts as a powerful natural repellent for many garden pests.
Key Takeaway: Mixing "distasteful" bulbs like Alliums and Daffodils with your tulips is a natural and beautiful way to create a pest-resistant flower bed.
Using Natural Deterrents and Repellents
If physical barriers aren't an option for your garden layout, you might consider using scent-based deterrents. These products work by making the soil or the bulbs themselves smell like something a squirrel wants to avoid.
Commercial Repellents
There are several commercial animal repellents available at garden centers. Many of these use natural ingredients like dried blood, putrified egg solids, or essential oils (such as peppermint or garlic).
Products like Plantskydd have earned a good reputation among gardeners for being long-lasting. These are often applied as a spray on the soil surface or as granules mixed into the planting hole. While these can be very effective, remember that most repellents need to be reapplied after heavy rain or snowmelt.
Household Solutions
Some gardeners swear by household items to keep squirrels at bay. Here are a few common suggestions:
- Black Pepper or Chili Flakes: Sprinkling these over the soil can irritate a squirrel's sensitive nose, discouraging them from digging. However, use caution and avoid over-applying, as you want to be kind to the local wildlife while protecting your plants.
- Crushed Garlic: Mixing crushed garlic into the soil near your bulbs can mimic the scent of Alliums and provide a similar deterrent effect.
- Soap Shavings: Some people find that scattering shavings of strongly scented soap (like Irish Spring) around the garden beds helps keep squirrels away.
- Prickly Materials: Scattering holly leaves or thorny rose clippings over a freshly planted bed creates a "prickly" surface that squirrels don't like to touch.
While these methods can work, they are usually less permanent than physical barriers or interplanting. They are best used as a secondary layer of protection during the first few weeks after planting.
Protecting Your Spring Blooms
Sometimes, the challenge isn't just protecting the bulbs in the fall; it's protecting the flowers once they emerge in the spring. While rare, some squirrels develop a taste for tulip blossoms. This is often a learned behavior in specific neighborhoods where squirrels have discovered that flower heads are a source of moisture and nutrients.
If you notice your flower heads being clipped off, you can use a spray repellent directly on the stems and buds. Look for a clear, scent-based repellent that won't stain the delicate petals. Another option is to keep a birdbath nearby. Sometimes squirrels eat flowers simply because they are thirsty during a dry spring. Providing a clean water source can often distract them from your flower beds.
Remember that this behavior usually only lasts for a short window of time. Once the spring rains arrive and other food sources become available, squirrels typically move on to other things.
Timing Your Planting for Success
In gardening, timing is often more important than any specific trick. Squirrels are most active in their food-gathering "frenzy" during the early fall when the weather is still warm. If you plant your bulbs too early, you are placing them in the garden right when squirrels are most motivated to dig.
We recommend waiting to plant your tulip bulbs until the soil temperature has cooled down to about 55°F or lower. In most regions, this happens after the first frost of the season. At this point, the squirrels have usually finished most of their winter caching, and the cooler air makes them less active.
Planting in late October or November (depending on your USDA hardiness zone) is often the "sweet spot" for avoiding the worst of the squirrel activity. If you aren't sure of your zone, you can check our shipping information for a schedule based on your location. We time our shipments to arrive roughly two weeks before the ideal planting time for your specific area.
Simple Gardening Rules for Tulip Success
To wrap up, most of your success will come from getting the basics right. We believe gardening should be a joy, not a struggle. Here is a quick summary of the simplest ways to ensure your tulips thrive:
- Right Plant, Right Place: Choose a spot with well-drained soil and plenty of sunlight (at least 6 hours a day). If you have a high squirrel population, consider a mix of tulips and daffodils.
- Depth is Your Friend: Always plant your tulips 6 to 8 inches deep. This simple step solves many common problems.
- Clean Up After Yourself: Removing the scent of the bulbs by picking up tunics and firming the soil goes a long way toward "hiding" your garden from curious eyes.
- Water Once: Water your bulbs well immediately after planting to help settle the soil and start root growth. After that, nature usually provides enough moisture through the winter unless you live in a very arid climate.
- One Step at a Time: If you are new to gardening, start with one or two methods. You might find that simply planting deeply and mulching is all you need for your specific yard.
What to do next:
- Wait for the soil to cool down before you start planting.
- Choose a balanced mix of your favorite tulips and some squirrel-resistant companions.
- Keep a bag of mulch or a pile of leaves ready to cover your work as soon as you are done.

FAQ
Does coffee grounds keep squirrels from digging up bulbs?
Some gardeners find that the strong scent and gritty texture of coffee grounds can act as a mild deterrent. You can sprinkle used coffee grounds on the surface of the soil after planting. While not a guaranteed fix, it is a safe, natural addition to your camouflage strategy and adds a small amount of nitrogen to the soil as it breaks down.
Will squirrels dig up tulips after they have started growing?
It is very rare for squirrels to dig up bulbs once they have established roots and started growing in the spring. At that stage, the soil is usually firm, and the bulb is no longer "fresh" and aromatic. Most squirrel interference happens in the first few weeks after the bulbs are planted in the fall.
Can I plant my tulips in pots to keep them safe from squirrels?
Yes, planting in containers is an excellent way to protect your tulips. You can easily cover the top of the pot with a piece of chicken wire or a heavy layer of decorative stones. Pots also allow you to move your display to a porch or patio where squirrels may be less likely to venture.
Do squirrels eat the leaves of tulip plants?
Generally, squirrels are not interested in the green leaves of tulips. If you see foliage being eaten, it is more likely the work of rabbits or deer. If you suspect squirrels are the culprits, it is usually because they are looking for moisture, so providing a birdbath or water dish nearby can help.
