The Unfortunate Truth: Why Animals Are Attracted to Your Dahlias

First, let’s get one thing straight: you haven’t done anything wrong. Dahlias are simply delicious to a variety of critters. Unlike some other garden plants like foxglove or daffodils, dahlias aren’t toxic to most animals, making them a perfectly fine meal in their eyes.

Animals are drawn to different parts of the dahlia plant during its life cycle, which is a key part of our investigation.

  • The Tubers: Think of dahlia tubers as little potatoes—starchy, full of energy, and an absolute delicacy for animals that dig. They are especially vulnerable right after you plant them in the spring.
  • The New Shoots: As those first tender green shoots emerge from the soil, they are succulent, soft, and irresistible to nibblers. They’re the dahlia equivalent of fresh spring asparagus.
  • The Leaves and Stems: Throughout the growing season, the foliage provides a steady source of food for browsing animals.
  • The Buds and Flowers: For many animals, the flower buds and petals are the sweetest part—a sugary, high-energy treat worth reaching for.

Do Animals Eat Dahlias? Identifying the Most Common Garden Intruders

Alright, let’s get down to business and create a “most wanted” list. Knowing who you’re up against is the first step in creating an effective defense. Here are the most common culprits you’ll find munching on your dahlias.

The Number One Suspect: Deer

If you live in an area with a deer population, they should be your primary suspect. Deer are browsers, and they aren’t particularly picky eaters, especially when other food sources are scarce.

They can do a tremendous amount of damage in a single night, often eating the entire top half of a plant, including leaves, stems, and any precious flower buds. Their damage is often ragged and torn, as they lack upper incisors and have to rip and pull at the foliage.

The Low-to-the-Ground Nibblers: Rabbits & Groundhogs

These critters are masters of stealth. You often won’t see them, but you’ll certainly see their handiwork. Rabbits and groundhogs (or woodchucks) target younger, more tender plants.

Look for damage low to the ground. The tell-tale sign of a rabbit is a clean, sharp, 45-degree angle cut on the stems. It looks almost like someone came through with a tiny pair of pruning shears. Groundhogs are less precise and can mow down several plants in one sitting.

The Underground Thieves: Squirrels, Chipmunks, and Voles

If your dahlia plants are disappearing before they even have a chance to sprout, you might have an underground thief. These animals are primarily after the tubers.

Squirrels and chipmunks will dig up newly planted tubers and carry them away. You’ll see disturbed soil and a small hole where your tuber used to be. Voles, on the other hand, create runway tunnels just under the surface of the soil or mulch and will eat the tubers from below, often leaving the plant to mysteriously wilt and die.

The Slimy Marauders: Slugs & Snails

Don’t underestimate these small but mighty pests. Slugs and snails can wreak havoc, especially in damp, shady conditions. They are most active at night, so the damage appears as if by magic in the morning.

Their damage consists of irregularly shaped holes in the leaves and petals. The dead giveaway, of course, is the shimmering slime trail they leave behind as evidence of their late-night feast.

Reading the Clues: How to Tell What’s Eating Your Dahlia Plants

Becoming a garden detective is a crucial skill. Before you can implement a solution, you need to be sure you’ve identified the right problem. Here’s a quick-glance guide to help you analyze the crime scene.

  • The Damage: Ragged, torn leaves and missing flower heads, typically a foot or more off the ground.

    The Culprit: Almost certainly deer.

  • The Damage: Clean, angled cuts on lower stems of young plants.

    The Culprit: Very likely rabbits.

  • The Damage: Dug-up soil and missing tubers, especially in spring.

    The Culprit: You’re probably dealing with voles.

  • The Damage: Irregular holes in leaves and petals, accompanied by a silvery slime trail.

  2. For Rabbits: A 2-3 foot tall fence made of chicken wire or hardware cloth with small openings is perfect. The most important tip is to bury the bottom 6 inches of the fence underground to stop them from digging under it.
  3. For Tubers: To protect tubers from diggers like squirrels and voles, plant them in “bulb cages.” You can buy these or make your own from hardware cloth. It’s a fantastic pro tip that saves so much heartache.
  4. For Young Plants: Individual plant protectors or cloches can be placed over new shoots until they are large enough to be less tempting.

  • DIY Repellents: You can make your own spray by mixing crushed garlic, a few hot chili peppers, and a drop of dish soap with water. Let it steep overnight, strain it, and spray it on your plants.
  • Scent Deterrents: Hanging fragrant bar soaps (like Irish Spring) or bags of human hair around the garden can confuse and deter deer.

Are dahlia plants poisonous to dogs or cats?

Dahlias are considered mildly toxic to dogs and cats by the ASPCA. Ingesting the tubers or plant parts can cause mild gastrointestinal upset like vomiting or diarrhea, but they are not considered life-threatening. It’s always best to discourage pets from chewing on any garden plants.
