Introduction
There is something truly magical about watching the first sprouts of a canna lily emerge from the soil in late spring. These tropical-looking plants bring an unmatched energy to the garden with their bold, paddle-shaped leaves and vibrant, orchid-like flowers. At Longfield Gardens, we love how cannas can transform a standard backyard into a lush, private oasis with very little effort.
If you have ever spotted a squirrel scurrying across your flower beds, you might feel a flicker of concern for your newly planted rhizomes. It is a common question for many gardeners: do squirrels eat canna bulbs? Understanding the habits of your local wildlife is the first step toward a successful growing season. This guide will help you identify whether squirrels are a genuine threat to your cannas and provide simple, effective ways to keep your garden looking its best.
While squirrels are often blamed for garden mischief, they are rarely the ones responsible for eating cannas. Most often, any damage caused by squirrels is due to their natural curiosity rather than a search for a meal. By following a few easy steps, you can ensure your canna lilies grow tall and beautiful without any unwanted interference.
Do Squirrels Eat Canna Bulbs?
The short answer is no, squirrels do not typically eat canna bulbs. In fact, what gardeners call "bulbs" are actually thick, fleshy underground stems known as rhizomes. To a squirrel, these rhizomes are generally unappealing. Squirrels much prefer high-fat, high-protein snacks like acorns, walnuts, and birdseed. They also enjoy starchy treats like tulip bulbs, which have a flavor profile they find much more attractive.
Canna rhizomes have a texture and taste that most rodents simply do not enjoy. They are often described as being somewhat bitter or woody. Because of this, it is very rare to find a squirrel actually sitting down to a meal of canna rhizomes. If your cannas are being eaten from underground, the culprit is likely a different animal entirely.
However, just because they don't eat them doesn't mean squirrels won't bother them. Squirrels are famous for their digging habits. They love to explore freshly turned soil because it is easy to move and often contains hidden treasures like buried nuts or the bulbs of other plants they find tasty. When you plant a new canna, the disturbed soil is an open invitation for a squirrel to investigate. They may dig up the rhizome, realize it isn't what they were looking for, and leave it sitting on the surface to dry out.
Key Takeaway: Squirrels rarely eat cannas because they find the taste unappealing. Most damage occurs when squirrels dig in loose soil and accidentally displace the rhizomes.
Identifying the Real Culprits
If you notice that your canna rhizomes are actually being eaten—meaning chunks are missing or the entire plant has vanished—you are likely dealing with a different garden visitor. While we want to keep the garden a happy place, it helps to know which neighbor is stopping by for a snack.
Voles and Gophers
Voles and pocket gophers are the most likely suspects for underground damage. Unlike squirrels, these small rodents spend most of their time beneath the surface. Voles look like stout mice with short tails and have a hearty appetite for roots and tubers. Gophers are larger and can pull an entire plant down into their tunnel system. If your canna sprouts and then suddenly wilts or disappears, look for small holes or mounds of soil nearby.
Raccoons and Skunks
Sometimes, the digging you see isn't about the plants at all. Raccoons and skunks often dig in garden beds to find grubs or insects. Because they are much larger than squirrels, they can do a significant amount of damage in a single night. They might toss your canna rhizomes aside while hunting for a high-protein insect meal. If the soil looks like it has been "roto-tilled" in small patches, these nocturnal visitors are likely the cause.
Deer and Rabbits
Cannas are generally considered deer and rabbit resistant. This is one of the many reasons we enjoy growing them! Most deer find the thick, fibrous leaves of cannas difficult to chew and digest. However, in areas where food is very scarce, a hungry deer might take a nibble of the new, tender growth. Rabbits may also investigate young sprouts but usually move on to tastier greens like lettuce or clover.
Simple Ways to Protect Your Canna Rhizomes
If you are concerned about squirrels digging up your cannas or other pests causing trouble, there are several easy ways to protect your garden. Most of these methods focus on making the soil less attractive for digging or creating a physical barrier.
The Wire Mesh Method
One of the most effective ways to stop digging is to use chicken wire or hardware cloth. This creates a physical barrier that squirrels cannot get through. After planting your canna rhizomes at the correct depth, lay a piece of wire mesh over the top of the soil. Secure the edges with landscape staples and cover the mesh with a thin layer of mulch.
The canna sprouts will be able to grow right through the holes in the wire, but squirrels will find it impossible to dig. This is a "set it and forget it" solution that works exceptionally well for the first few weeks after planting when the soil is most vulnerable.
Using Crushed Stone or Gravel
Squirrels love soft, easy-to-dig dirt. You can make your planting site much less appealing by mixing a bit of crushed stone or coarse gravel into the top inch of soil. The rough texture is unpleasant on a squirrel's paws, and they will quickly decide to dig somewhere else. This method also helps with drainage, which is a win-win for your cannas.
Natural Repellents
If you prefer a scent-based approach, there are many natural repellents available. Squirrels have a very sensitive sense of smell and are easily deterred by strong odors. Some gardeners find success by sprinkling dried blood meal or black pepper around the planting area.
Another popular option is to use a spray made from garlic or hot peppers. While these need to be reapplied after heavy rain, they are a simple and safe way to keep curious critters away.
"What to Do Next" Summary
- Identify the issue: Check if the rhizome is actually eaten or just dug up.
- Protect the soil: Use wire mesh if squirrels are digging in your beds.
- Improve the texture: Add a layer of gravel or mulch to discourage curious paws.
- Monitor growth: Watch for new sprouts and ensure they have plenty of water.
Planting for Success
The best way to ensure your cannas thrive is to get the basics right from the very beginning. When a plant is healthy and vigorous, it is much more resilient to minor stresses, including curious wildlife.
Right Plant, Right Place
Medium Cannas, like all cannas, are sun-loving plants. To get those big, beautiful leaves and tall flower stalks, they need at least six hours of direct sunlight every day. They also love heat. If you live in a cooler climate, the wait for warm soil is exciting and worthwhile. We recommend waiting until the soil temperature reaches at least 60°F before tucking your rhizomes into the ground.
Depth and Spacing
Getting the planting depth right is a quiet winner for garden success. Most canna rhizomes should be planted about 2 to 3 inches deep. If you plant them too shallowly, they are much easier for squirrels to uncover. Spacing is also important; give them about 1 to 2 feet of room so they have space to spread their roots and grow into their full, clumping habit.
Watering and Soil
Cannas are thirsty plants. They naturally grow in damp areas, so they appreciate consistent moisture. However, they also need soil that drains well. "Drainage" simply means how fast water leaves the soil. You want the soil to stay moist like a wrung-out sponge, not soggy like a puddle. If your soil is very sandy, you may need to water more frequently. If it is heavy clay, adding some compost can help improve the structure.
Key Takeaway: A well-planted canna is a strong canna. By focusing on sun, soil, and proper planting depth, you give your plants the best start possible.
Growing Cannas in Containers
If your garden has a high population of squirrels or other digging animals, growing cannas in containers is a fantastic solution. Containers offer several advantages when it comes to pest protection.
First, pots are much easier to monitor. You can place them on a patio or deck where squirrels may feel less comfortable hanging out. Second, the limited surface area of a pot makes it very easy to protect. A small piece of wire mesh or a layer of decorative stones on top of the soil will stop almost any digging in its tracks.
Cannas also look stunning in pots. Short Cannas are particularly well-suited for container gardening, providing a burst of tropical color without taking up too much space. You can even combine them with other sun-loving plants like lantana or sweet potato vine for a professional-looking arrangement.
Container Tips
- Choose the right size: Ensure the pot has plenty of room for the rhizome to grow. A 12-inch pot is usually the minimum for a single plant.
- Drainage holes are a must: Make sure your container has holes at the bottom so excess water can escape.
- Use high-quality potting mix: This provides the light, airy structure that cannas love.
Winter Care and Storage
In many parts of the United States, cannas are treated as annuals or need to be lifted for the winter. This is another time when you might encounter squirrels. If you live in a cold climate (typically USDA zones 7 and lower), you will want to dig up your rhizomes after the first frost has blackened the foliage.
Once you have lifted the rhizomes, let them dry in a protected area for a few days. This is the stage where you want to keep them out of reach of curious animals. While they still won't want to eat them, squirrels may try to carry them off if left out in the open.
Store your rhizomes in a cool, dark, frost-free place, such as a basement or crawl space. Many gardeners tuck them into boxes filled with peat moss or vermiculite to keep them from drying out completely. This winter rest is an essential part of the canna life cycle, and it is exciting to know that the same plant will return even bigger and better next year.
Troubleshooting Common Canna Questions
Sometimes, gardeners worry about squirrels because their cannas aren't growing as expected. Before assuming an animal is to blame, check these common factors.
Why won't my canna bloom?
If your canna has plenty of leaves but no flowers, the most likely cause is a lack of sunlight. These plants are sun-worshippers! If they are in too much shade, they will focus all their energy on foliage. Another factor can be nutrition; a balanced, slow-release fertilizer can provide the boost they need to produce those showy blooms.
Why is my canna growing so slowly?
Canna lilies are tropical plants that love heat. If the spring is unusually cool or damp, they may take their time to get started. Be patient—once the summer heat arrives, cannas often grow several inches in a single week. Framing this wait as a period of anticipation makes the eventual bloom even more rewarding.
What are these holes in the leaves?
While squirrels don't eat the leaves, some insects do. The most common pest for cannas is the canna leafroller. These are small caterpillars that stitch the leaves together before they unfurl. If you see holes or rolled leaves, you can simply unroll them and remove the caterpillars by hand or consult your local extension service for the best organic controls in your area.
Encouraging a Diverse Garden
It is helpful to remember that a garden is a living ecosystem. Squirrels, birds, and even the occasional rabbit are all part of the outdoor experience. By choosing plants like cannas that are naturally resistant to being eaten, you are already one step ahead.
Gardening is a journey of observation and small adjustments. If you see a squirrel digging, don't feel discouraged. It is simply a sign that your soil is healthy and easy to work with! A quick fix like a handful of gravel or a piece of wire mesh is all it takes to keep the peace between your plants and your backyard visitors.
At Longfield Gardens, we believe that every gardener can find success by focusing on the basics. When you provide the right environment, nature does most of the hard work for you. Cannas are incredibly resilient and rewarding plants that ask for very little in exchange for their spectacular summer show.
Conclusion
Squirrels are rarely a threat to the life of your canna lilies. While they may dig in the soil out of curiosity, they find the taste of the rhizomes unappealing. By using simple physical barriers like wire mesh or adding texture to your soil, you can easily protect your planting beds. Focus on providing plenty of sun, consistent water, and the right planting depth to ensure your cannas reach their full potential.
- Protect the soil: Use mesh or gravel to stop curious digging.

FAQ
Do squirrels eat canna lily flowers or leaves?
No, squirrels generally do not eat canna lily flowers or leaves. The foliage is thick and fibrous, which makes it unpalatable for most rodents and even deer. If you see holes in the leaves, it is much more likely to be caused by insects such as snails, slugs, or canna leafrollers.
Why do squirrels dig up my canna rhizomes if they don't eat them?
Squirrels are naturally curious and are drawn to freshly disturbed soil. They often dig in garden beds looking for nuts they previously buried or searching for the bulbs of other plants they find tasty, like tulips. Once they dig up a canna rhizome and realize it isn't food, they usually leave it on the soil surface.
What is the best way to stop animals from digging in my flower beds?
The most effective method is to create a physical barrier using chicken wire or hardware cloth. Laying the wire over the soil after planting prevents animals from reaching the rhizomes. Other simple options include adding a layer of mulch, using crushed stone, or applying a natural scent-based repellent like garlic or pepper spray.
Are canna lilies toxic to dogs or cats?
According to the ASPCA, canna lilies are considered non-toxic to dogs, cats, and horses. This makes them a wonderful choice for pet owners who want to create a beautiful landscape without worrying about their furry friends. However, it is always a good practice to discourage pets from digging in the garden to protect both the plants and your landscaping.
