Do Deer Eat Asters? (Here’s The TRUTH & 11 Ways To Protect Your Garden)

As a nature lover and avid deer enthusiast, I’ve often wondered, do deer eat asters? After conducting extensive research and observing these majestic creatures in their natural habitat, I’ve discovered the truth about these beautiful flowers and their relationship with deer.

During late summer and fall, when food sources are scarce for deer, they may sometimes turn to the flowers of asters. However, asters aren’t exactly their favorite food, and they generally don’t find them very appealing. The bigger threat to asters is actually rabbits, who seem to love them and can cause severe damage throughout the year.

Do Deer Eat Asters?

Gardeners often ponder whether asters are a favorite of deer. Although deer have been known to nibble on aster blooms, they tend to find the texture unappetizing and therefore rarely indulge. Conversely, rabbits have a voracious appetite for asters and can easily inflict damage on the plant any time throughout the growing season. This is an important consideration for gardeners seeking to mitigate wildlife-related harm to their blossoming crops.

Reasons Why Deer Eat Asters Plant

Deer tend to feed on asters when other food sources are scarce in the late summer and fall. Despite this, the grazing behavior of deer towards asters is mostly limited to the flowers rather than the entire plant. Therefore, asters are not typically a significant part of deer’s diet. Other animals, such as rabbits, pose a greater threat to asters.

Different Ways to Prevent Deer From Eating Asters

If safeguarding your asters from deer harm is a priority, there exist several approaches to accomplish this. One successful technique involves utilizing commercial repellents aimed at deterring deer, for example, the product Liquid Fence Deer and Rabbit. This solution appears to protect against these herbivores to a certain extent. Additionally, selecting perennial plants that are resistant to deer may prove fruitful, as these plants are less affected by grazing and can play a crucial role in maintaining the integrity of your garden.

What Makes a Perennial Plant Deer-Resistant?

Perennial plants that resist deer are typically characterized by their texture, taste, or scent. They have evolved to be less appealing to deer and other herbivores, which makes them a great option for gardeners who want to keep their plants safe from wildlife damage. Some perennial plants are also less susceptible to diseases and pests.

Characteristics of Deer-Resistant Plants

Deer-resistant plants are characterized by their ability to resist both deer and rabbits. These plants have evolved to deter herbivores through texture, taste, and scent. They tend to have a waxy or hairy leaf texture and produce spiky or thorny flowers. Some deer-resistant plants also have a distinctive scent or taste that deer find unpleasant.

Types of plants that deer and rabbits tend to avoid

Deer and rabbits are notorious for devouring gardens, but not all plants are on their menu. If you want to protect your precious greenery, consider planting species that these critters tend to avoid. Some examples include the prickly holly bush, fragrant lavender, pungent allium, and aromatic rosemary. These plants not only repel herbivores but also add beauty and scent to your yard. So, skip the pansies and petunias and opt for deer-resistant plants that are both lovely and low-maintenance.

Growing Tips and Suggested Planting Locations

When planting deer-resistant perennial plants, it’s essential to choose the right location. Most deer-resistant plants prefer full sun to partial shade and well-draining soil. If you are not sure about the soil type in your garden, you can take a soil sample to a local nursery or gardening center to be tested. Generally, deer-resistant plants are low-maintenance, and they do not require much water or fertilizer. However, you should still follow specific care requirements for each plant to ensure that it thrives in your garden.

Other Options for Garden Protection

Maintaining a garden can prove gnawing in the event that herbivorous animals, such as rabbits and deer, decide to make a meal out of your plants. Although selecting deer-deterring plants is crucial, there are multiple methods to safeguard your garden from these animals. Consider these alternatives to protect your plants from deer and rabbits:

1. Fencing

Deer are majestic creatures, but you don’t want them in your garden! Construct a fence that’s at least 8 feet high, made from heavy-duty material such as metal or plastic. You can also add a slanted top or double fence to deter them from jumping over. Remember to bury the fence at least 8-12 inches into the ground to prevent them from digging under it.

As an alternative, especially in more rural areas, you can also use an electric fence, however, make sure to place warning signs around it and be careful when passing nearby.

2. Use Deer-Resistant Plants

If you can’t beat them, plant things they don’t like. Deer tend to avoid plants with strong scents or prickly textures, so opt for fuzzy lamb’s ear, spiky yucca, fragrant lavender, and Russian sage. But keep in mind that no plant is completely deer-proof, so plant a mix of vegetables, herbs, and flowers to minimize their interest.

3. Motion-Activated Sprinklers or Lights

Motion-activated sprinklers or lights can startle deer and make them run for the hills! It’ll teach them to stay away from your garden. Sprinklers release a burst of water when it senses movement, while lights can make it harder for them to navigate around your garden.

Here are the best motion-activated sprinklers to keep deer out of your garden:

4. Deer Repellent Sprays

Deer repellent sprays are an excellent option for the chemically-averse gardener. They use a combination of ingredients, including garlic, hot pepper, and eggs, to create an unpleasant taste and scent that will keep the deer away. But remember to reapply after rainfall to ensure it remains effective.

Here’s the best deer repellent spray for you:

5. Hang Reflective Objects

Want to add some pizzazz to your garden while keeping deer out? Hang shiny objects such as CDs or aluminum foil strips. The reflection of light off these shiny items can confuse deer and keep them from coming towards your garden.

6. Physical Barriers

Protect individual plants or small garden areas by creating physical barriers, such as cages made from chicken wire or heavy plastic netting. Row covers are also effective in protecting sprouts and young plants from being eaten by deer.

Pro tip: you can even use a transparent fhishing line around your plants. Deer will be annoyed by it and leave. Just make sure to put at least 2 rows of wire at the right height.

7. Sound Deterrents

Deer have a keen sense of hearing, and certain sounds can frighten them away. Wind chimes or ultrasonic devices emit sounds that can deter deer from coming near your garden.

Here’s the best ultrasonic deer deterrent:

8. Smell Deterrents

Deer’s sensitive noses can be put to use! Human hair, soap, and rotten eggs are examples of strong scents that deer dislike. Spread these around the garden to discourage deer from coming close.

9. Natural Barriers

You can use nature to your advantage by planting holly or barberry bushes around the perimeter of your garden. Deer will avoid these prickly and thorny bushes. Alternatively, use a natural deer repellent such as bone meal or blood meal, which emit strong smells that deer dislike.

10. Clean Up Debris and Fallen Fruit

Old leaves, fruit, and debris attract deer, so clean up your garden regularly. By doing so, you’ll eliminate any potential food sources that might draw deer to your garden.

11. Rotate Your Methods

Deer are smart creatures, and they figure out how to outsmart your preventative measures. Rotate your tactics to keep them guessing. For example, start with building a fence, use sound deterrents or deer-resistant plants, then switch to natural barriers or deer repellent sprays. Keep mixing them up to keep them off-guard.


So, do deer eat asters? The answer is a bit complex – while not a favorite snack, deer will occasionally chomp down on these beautiful flowers when their other food sources are scarce. However, the bigger threat to asters actually comes from rabbits, who find them irresistible and can cause significant damage to the plant anytime.

So, if you’re looking to protect your asters from hungry critters, make sure to keep an eye out for cute little bunnies hopping around instead of just focusing on the more obvious deer. And remember, while asters may not be at the top of the menu for deer or even rabbits, it’s always better to be safe than sorry when it comes to protecting your garden!
