Do Deer Eat Lilacs? Best Deer-Resistant Flowers and Shrubs for Your Garden!

I am passionate about deer and nature, and I have always wondered: do deer eat lilacs? After researching, I have discovered the answer, along with the best deer-resistant flowers and shrubs for your garden. Protect your plants and keep your garden beautiful with these tips!

Do Deer Eat Lilacs?

Deer are not known for eating lilacs but may consume them if they have limited food options. However, it is more probable that insects and other visiting animals are responsible for damaging lilacs. It is crucial to protect these plants to maintain their beauty, and gardeners should take necessary measures to prevent damage by deer or other harmful wildlife.

Factors that Deter Deer from Eating Lilacs

If you have a deer problem, you may also have to consider ways to protect your lilacs. One effective method is to plant deer-resistant shrubs and flowers alongside your lilacs. This will discourage deer from approaching the area in the first place.

Busy roads or frequent human activity can also keep deer away, as they tend to avoid areas with high human traffic.Another option is to use deer repellent sprays. These sprays work by giving off unpleasant smells and tastes to deer, discouraging them from eating your plants. You can make your own at home using household items, or invest in commercially available repellents.

How To Protect Your Garden From Deer

If you’re tired of worrying about deer damage, consider including some deer-resistant flowers and shrubs in your garden. There are plenty of attractive options to choose from, such as lavender, hibiscus, boxwood, and barberry. These plants tend to have unpleasant tastes or smells that deer don’t like, making them ideal alternatives to lilacs.

Deer Repellent Sprays

Deer repellent sprays can be an effective method of keeping deer away from your lilacs. There are many different types of repellent sprays on the market, including homemade remedies and commercial products. Homemade sprays can be created with ingredients such as chili powder, garlic, and even hair clippings. Commercial repellents often use natural ingredients like essential oils, and some even have scents that humans find pleasant.


Perhaps the most effective way of keeping deer away from your lilacs is by fencing them off. This means building a fence that is at least eight feet tall, as deer can jump up to six feet high. Alternatively, some gardeners use double fences, with one fence about five to six feet tall and another around one to five feet away. This creates confusion for deer because they can’t see where they are landing.

Companion Planting

Companion planting is a technique whereby plants are grown together to benefit each other. By planting deer-resistant plants alongside your lilacs, you can create an environment that is less appealing to deer. Some examples of deer-resistant plants include salvia, alliums, and roses. These plants tend to have strong smells or tastes that deer find unappealing.

Let’s look more in detail at the lilac companion planting options!

Pest Repellent Plants to Protect the Garden

  • Lavender: The strong fragrance of lavender can repel deer and other pests.
  • Rosemary: This fragrant herb is another plant that deer dislike and will often avoid.
  • Sage: Like rosemary, sage has a pungent smell that can help deter deer.
  • Chives: Chives emit a strong smell that deer don’t like, making them a great option for companion planting.
  • Peppermint: Another fragrant herb, peppermint has the added benefit of attracting beneficial insects like bees and butterflies.

Plants That Attract Beneficial Insects

  • Yarrow: The delicate flowers of yarrow attract beneficial insects like ladybugs and lacewings, which can help keep pests like aphids under control.
  • Cosmos: Another attractive flower for beneficial insects, cosmos blooms throughout the summer and into the fall.
  • Dill: This herb’s flowers are a favorite of beneficial insects like parasitic wasps and predatory beetles, which can prey on pests that might attack your vegetables.

Deer-Resistant Companion Plants For Lilacs

  • Catmint: A member of the mint family, catmint has a strong scent that deters deer while also attracting bees and butterflies.
  • Daffodils: Spring-flowering bulbs like daffodils are generally not attractive to deer and can be planted around the base of your lilacs.
  • Foxglove: This tall flowering plant is poisonous to deer and can also add a pop of color to your garden.
  • Bleeding Heart: A shade-loving perennial, bleeding heart can be planted around the base of lilacs to add visual interest while also providing some deer protection.

Motion-Activated Sprinklers

A motion-activated sprinkler system might come in handy. These sprinklers are equipped with motion sensors that detect movement in the garden, and once triggered, the sprinklers spray a burst of water, startling the deer and discouraging them from returning.

The sprinklers can cover a large area, and the sudden burst of water also creates noise, which can deter not just deer, but other garden pests as well. Install a motion-activated sprinkler system in your garden, and watch as the deer stop trampling your flowers and plants.

Ultrasound Repellents

Ultrasound repellents are another option for those looking to repel deer and other wildlife from their garden. These devices emit high-frequency sound waves that are inaudible to humans but irritating to animals like deer.

The sound waves are meant to create a sonic barrier around the garden, keeping wildlife at bay. Although some studies suggest that ultrasound repellents may not work as effectively as other methods, they can still be a useful tool in conjunction with other repellents or as a preventative measure. Consider adding an ultrasound repellent to your garden to keep the deer and other pesky animals away.

Habitat Modification

Deer tend to live in wooded areas and avoid open spaces. If you live in an area where deer are abundant, you may have to consider modifying your garden to make it less appealing to them. This can include removing any tall grass or vegetation, as deer like to hide in overgrown areas. You can also use motion-activated sprinklers or lights to startle deer and deter them from approaching.

What is a Lilac?

Lilacs are undoubtedly some of the most beautiful flowers you can have in your garden. Known for their vibrant purple blooms, lilacs can easily add a pop of color to any landscape. Their unique fragrance is equally appealing and can be enjoyed from afar. These deciduous shrubs grow up to 15 feet tall, with their blooms appearing in early to mid-spring. Growing lilacs requires just a little bit of maintenance, such as pruning and fertilization, to keep them looking their best. They thrive in well-draining soil, spread through suckers, and can be propagated via cuttings.

How To Grow Lilacs

Lilacs are beautiful and fragrant flowering shrubs that can successfully grow in a wide range of climates, from cold northern regions to mild southern areas. Here are some tips on how to grow lilacs:

Choose the Right Variety

Lilacs come in many varieties, and picking the right one is crucial. You want a variety that will thrive in your climate and soil type. Common lilacs are the most popular, but smaller varieties such as Miss Kim are ideal for smaller gardens. Take some time to research the varieties that will work best where you live.

Ideal Soil

Lilacs prefer well-draining soil that is slightly alkaline. They thrive in loamy soil that is rich in organic matter, and they will appreciate a layer of mulch over their roots. Some gardeners add lime to their soil to increase its alkalinity, but this is not always necessary. It is also worth noting that lilacs do not like too much moisture, so be careful not to overwater them.

Lighting Requirements

Lilacs are sun-loving plants that need a minimum of six hours of sunlight daily to grow healthy and produce beautiful flowers. These shrubs can tolerate partial shade, but they may not bloom as much or may have less dense foliage.

Therefore, it’s essential to plant lilacs in an area where they can receive enough sunlight throughout the day.If you’re planning to add lilacs to your garden, make sure to choose a spot that gets morning or afternoon sun. This way, you can ensure that your lilacs are getting enough light while avoiding extreme heat that can stress the plants during hot afternoons.

Planting Time

Picking the right time to plant lilacs will determine their success. Plant in the fall or early spring when the soil is moist, and temperatures are cool. Summer can be an option too, but you’ll need extra care to prevent heat stress.

Watering and Fertilization

Lilacs require well-draining soil, and that is why they thrive in fertile, alkaline soil. Water is crucial for lilacs, especially during dry and hot periods. During the growing season, these plants need at least one inch of water per week.

Fertilize the plants with balanced nitrogen-phosphorous-potassium (NPK) fertilizer at the beginning of each spring. This will encourage the shrub to produce flowers during the blooming season.It’s also essential to prune the shrub, especially after blooming, to maintain its shape and remove dead or sickly branches. Cut back up to a third of the shrub’s length and shape it as desired.

If it doesn’t rain enough, you need to water them regularly. However, over-watering or low-quality drainage can lead to water-logging and root rot or other problems.To keep your lilacs healthy, add a layer of mulch around their base. This will help retain soil moisture and keep the area cool; it also stops weed growth.


Pruning is essential to the health of your lilacs. Removing dead or damaged wood, promoting airflow between stems, and encouraging new growth is crucial to keep your lilacs looking their best. Prune immediately after flowering to avoid removing the following year’s flower buds.


Can trees heal after being damaged by deer?

Deer can cause harm to trees, but it is possible for the trees to recover. Typically, the best time for this to happen is in the spring and early summer when new growth begins. With proper care and pruning techniques, trees can heal more quickly and regain their strength.

Which season do deer harm trees?

During the mating season, bucks have a tendency to rub their antlers against the trunks of trees, causing damage that can hinder the tree’s natural healing process. However, by utilizing proper pruning methods, recovery time can be expedited. It’s vital to keep in mind that healthy foliage can usually replace any damage sustained during the autumn or winter months.

Do shrubs regenerate after deer consumption?

Deer often feast on shrubs and foliage, leaving homeowners wondering if their plants will grow back. The good news is that as long as the roots have not been completely destroyed, most shrubs can regrow foliage in the spring or early summer. It may take some time for the plant to recover, but with proper care and maintenance, it should return to its former glory. Consider fencing or other deterrents to prevent further damage.


So, do deer eat lilacs? The answer is not a straightforward yes or no. While deer are not known to actively seek out lilacs as a food source, they may still consume them if other options are limited. However, it is often other culprits such as insects and visiting animals that cause damage to these beautiful plants. As a gardener, it is important to take necessary measures to protect your lilacs and preserve their beauty.

Fortunately, there are many deer-resistant flowers and shrubs that can be planted in your garden to avoid such issues altogether. From marigolds and daffodils to boxwood and yucca, there are plenty of options available. With a little bit of research and careful planning, you can create a garden that not only looks great but is also resistant to pests and wildlife. Happy gardening!
