Lilac borer larvae, which eat the plant’s sapwood, are the main cause of damage to lilacs. Another pest that harms lilacs is the scale insect, which feeds on the sap of the plant’s leaves, stems, and roots.
Who or what consumes lilac bushes?
Lilac bushes are not eaten by deer. Deer would generally avoid them because of their offensive fragrance. Never forget though that no plant is completely deer-proof.
Even if lilac plants occasionally and only rarely have seriously damaged kinds, they are still edible.
During the winter or during times when there are few other food sources, deer will probably devour the lilac shrubs. Because deer will gladly eat lilac bushes when they are young, it also occurs then. There’s a good probability that lilac bushes, if they’re native to your area, will end up being a deer’s preferred food.
What is destroying my lilac shrubs’ leaves?
The lilac, privet, and ash leaves are the primary food source for the caterpillars of the lilac leaf mining moth. As a result, the leaves develop brown spots and begin to roll up from the tip.
Can lilac bushes be eaten by rabbits?
This fall-planted bulb has a distinctly “skunky” smell. Animals will avoid the area since they can smell the flowers or greenery even if you can’t.
When planting, place 1 inch of coarse sand under the bulb since crown imperial needs adequate drainage. And plant the bulb on its side to avoid water from condensing in the top.
Sprinkle fertilizer all around your crown imperials in the early spring as soon as you notice the stems peeking through. Find a general-purpose bulb food with a 9-9-6 analysis. Snip off the blooms once they have faded, but save the foliage to nourish the bulb. After the bulb goes dormant, keep the soil dry.
The big-flowered alliums will still be preparing to put on their display after the deer and rabbits have devoured all of the tulips. The iconic flower in the image above, “Gladiator,” has blooms that can endure up to three weeks. The globes will continue to stand even after the foliage withers, which usually happens before the flowers are finished and the color dries up.
Even if a single specimen is impressive, planting in groups has a greater impact. Per square foot, allow two to three bulbs. They can cost more than other spring bulbs, which is true, but their flowers often persist longer than tulips or daffodils.
Toxic to both humans and other creatures like deer and rabbits, foxgloves are poisonous in all sections. They are aware to leave this plant alone, somehow.
Foxglove with narrow leaves is infamous for dying quickly. By preventing it from setting seeds, you can attempt to extend its life for several years and increase the number of blossoms you get in the process. The plant may use up all of its energy ripening the seeds and die throughout the winter if you fall behind in deadheading and seeds form. If so, allow the seeds to fall to the ground and search for seedlings the following spring. The first year, they most likely won’t blossom, but mark them so you can enjoy the flowers the following year.
Deer and rabbits won’t likely enter a bed in search of food if the edge is made unpleasant to them. This mounding plant looks great in a container or as a low border. Most cultivars feature flowers that are lavender-blue, like this one’s “Blue Pearl.” All of them prefer full light, however in USDA zones 8 or warmer, afternoon shade keeps the color the best.
Not even deadheading is necessary. New growth and flower buds typically cover the old vegetation as the blooms fade. The plant may become a little bit lanky with time. Your plants will start blooming again in a week or two if you lightly shear or clip a couple of inches from the top.
Traffic can be stopped when the flower stalk of this lovely shrub is covered in creamy white bells in the summer. Additionally, it will deter passing hummingbirds from stopping by for a taste of nectar. Deer and bunnies, meanwhile, won’t even nip at the stringy, stiff foliage. The leaves of ‘Variegata’ are blue-green with creamy yellow edges. The evergreen trees’ leaves become rosy pink in the fall.
Spanish dagger is actually a shrub, but because it grows so slowly, most people grow it as a perennial. It will eventually grow a trunk that elevates the leaf rosette after around 10 years, making a remarkable focal point.
Lilacs might be found blossoming carelessly in abandoned lots. One explanation for why lilacs thrive when left alone? Deer and rabbits ignore them in favor of chewing on more appetizing objects.
Here, there are Persian lilacs that are incredibly fragrant and resemble well-known French hybrids. But compared to its well-known cousins, it appears a little bit smaller and more fragile.
The fact that most lilacs bloom for such a brief period of time is their worst flaw. Plant a variety of deer- and rabbit-resistant plants and cultivars. You can do this to extend the season of color and scent for as long as a month.
How can I keep my lilac bushes safe?
Lilacs are more resilient than other plants to a chilly winter. If there is no precipitation accessible to the roots, they do benefit from sporadic watering. Winter protection for lilacs is provided by watering close to the root zone, which actually maintains the soil warmer than dry soil.
Rarely, you might have to cover the plant to keep the buds safe. When buds are just starting to open in late winter or early spring, a severe freeze strikes. Cover the shrub with a blanket, canvas, or even a plastic tent to help shield the buds from the cold. If it gets warm enough during the day, take it off so the plant may enjoy some sunlight and air.
How can lilacs be protected from squirrels?
Due to the numerous stems that lilac bushes have, which squirrels may climb and jump on, keeping them out of your lilac bushes might be difficult. Consider coating the shrub’s lower trunks in metal flashing. This will shield such areas from harm and possibly deter squirrels from scaling. Plant shrubs far from trees, homes, and fences to prevent squirrels from leaping from these structures into the lilacs.
Do deer consume lilac shrubs?
Lilacs may be vulnerable in the first few weeks after planting, despite their deer resistance designation. The shrub should live even if it has been nibbled on as long as the root structure is unharmed. A lilac plant can be almost completely destroyed and still recover and thrive. Lilac plants are tough and can actually benefit from pruning, even if it isn’t done on purpose.

What is lilac bush in my yard dying?
The most typical tree disease that affects lilac trees is powdery mildew. Plants with this fungal infection develop more slowly, and in certain situations, they may die. Watch out for a white, flour-like substance on the leaves of your lilac plant. If you do have powdery mildew, get rid of all the affected plant portions and use a fungicide.
Inquire about scale, lilac borer, and other problematic pests from your tree service professional.
Tip
Lilacs can also be harmed by various illnesses, as well as by borers, aphids, scales, and societal issues. Look for indications of insect infestation on the plant, such as holes in the wood, black smut, or honeydew-like sticky material. Remove borer-infested branches that have holes in the base from the tree. In the spring, use insecticidal oil to treat aphids and scales.
Shoot blight results in blackened roots as well as shoots, as opposed to merely leaves, shoot tips, and flowers, like lilac blight. Since this illness is more severe than lilac blight, affected plants should often be pulled out. Witch’s broom results in twisted, gnarly growths. Remove plants that have been seriously harmed or prune diseased branches.
Most lilacs require winter cooling to flower successfully and are only hardy in USDA zones 3 through 7. These lilacs won’t blossom and can be more prone to disease in warmer climates. Purchase low-chill, disease-resistant types bred for warm coastal areas in moderate climes.
What species of insects are drawn to lilacs?
Your lilac, candytuft, and grape hyacinth blossoms are being invaded by tiny insects known as thrips, possibly Frankliniella occidentalis, often known as western flower thrips. Thrips tend to be a problem with landscape flowers early in the season since they are drawn to blossoms of brilliantly colored flowers.
How can I keep my rabbits’ lilacs safe?
In the winter, rabbits can seriously harm trees and plants. They are most active at night. You wouldn’t have noticed their footprints if they were eating in your garden because there hasn’t been any snow cover so far this year, nor would you anticipate seeing them during the day. Both in the winter and during the growing season, it is a good idea to frequently walk through your garden to check for animal damage.
By gnawing off little branches and girdling huge stems, rabbits harm bushes. During the winter, rabbits consume woody plants by nibbling on the bark or removing the buds, ends of stems, and branches. Rabbits consume the tissue that lies between the wood and the bark. They typically avoid older trees and plants’ thick, rough bark in favor of the smooth, thin bark, which is an easier food source for them. But on mature-barked plants, the rabbits do target the young, smooth-barked twigs.
Keep an eye out for plant damage caused by rabbits near the snow line or a few feet above the ground. The extent of damage rises when there is snow cover since the rabbits will feed by climbing higher on the plants. On twigs with a small diameter, rabbits leave a neat, angled cut at a about 45-degree angle. Look for little, spherical, brown mounds of scat that are about 3/8 inch in diameter—these are rabbit droppings. Similar in size and shape to human excrement, deer excrement is more oblong. The morphology of rodent excrement is more tubular.
Installing chicken wire fencing or hardware cloth with apertures no larger than 1 inch around vulnerable plants is an efficient approach to stop rabbit damage to trees and shrubs in your garden. The fencing material should be 24 to 36 inches high to effectively protect plants and to deter rabbits from scaling it after a snowstorm. To keep rabbits from climbing under the fencing, secure the bottom with stakes. If the ground is not frozen, U-shaped sod pegs or burying the wire ends 3 to 4 inches below the surface work well for this.
Smaller bushes can be covered with plastic garden netting to deter rabbits. To deter rabbits, wrap the wire around the trunks of tiny trees or install white spiral tree guards around them. Check protected plants to make sure rabbits can’t climb over fencing or tree guards after a significant snowfall. To prevent rabbits from getting to the trees or shrubs, it might be essential to remove some of the snow.
In order to deter rabbit grazing, you can also spray the afflicted bushes with a repellent that has an unpleasant taste and smell. It is recommended to use repellent when it is above freezing and to reapply after it has rained or snowed heavily. False predator figures, like owls and hawks, used to scare or frighten away bunnies, are ineffective.
Because the flow of food and water has been impeded, any branches or trunks that have had the bark entirely stripped surrounding them typically die as a result. A process known as bridge grafting, which should be handled by a qualified practitioner, may be used to save valuable trees.
The best course of action is typically to replace the girdled tree. The majority of deciduous shrubs near their base will sprout new shoots or suckers and eventually recover. In order for the shrub to recover, prune the girdled stems immediately below the injured portions in the early spring.

How can I prevent bunnies from consuming my plants?
- Given that rabbits have such keen senses of smell, sprinkling powdered red pepper throughout the garden or on certain plants may deter them.
- It has been suggested that scattering shavings of Irish Spring soap throughout the garden in small drawstring bags can deter rabbits.
- By blending three fiery peppers, three sizable onions, and a whole amount of garlic, you can make a foul-tasting rabbit cocktail. Overnight, cover with water and place in a container. After straining, mix the ingredients with a gallon’s worth of water. Spray plants again after a rainstorm. Try commercial goods made with strong garlic oil as well.
- Spray one teaspoon of Lysol and one gallon of water around your plants.
- Some individuals use individual “tin can collars” or screens to protect plants, allowing them to grow to a less vulnerable size. For safety, wrap the collar around each stem.
- Use hardware cloth cylinders with a 1/4-inch mesh to prevent rabbits from nibbling on young fruit and ornamental trees. The cylinders should stand one to two inches away from the tree stem and be higher than a rabbit might reach when standing on the anticipated depth of snow.
- Some odor-based deer tactics are claimed to also be effective against rabbits. Commercially marketed deer repellents that combine dried bovine blood, sulfured eggs, and garlic will keep rabbits away.
- Try an old-fashioned rabbit cure and scatter big, clear glass jars of water throughout the garden. According to legend, rabbits are afraid of their own reflection. Reflectors and other items are offered by garden centers. Bunnies can be scared away from your plants with the help of lurking cats, phony snakes, and ominous owls.
- Humane traps can be the best option in some situations. (Take note that it can be against the law to capture and release wild animals in your region.) Consider creating a trap if you don’t want to purchase one. Put the trap in the area where you’ve noticed the rabbits eating or relaxing, then cover it with a canvas. Apples, carrots, cabbage, and other vibrantly green fruits and vegetables make great lures.
Plants That Rabbits Dislike
Experts on bunnies claim that rabbits have specific plant preferences based on a variety of factors, including flavor, nutritional value, the presence of poison or prickles, and accessibility. Not all plants are suitable for all rabbits because their interests in diet might vary by place and season. Be cunning and take care of plants that rabbits don’t find particularly appealing.
Rabbits frequently steer clear of certain plants that deer and Japanese beetles do. Check out our lists of deer-resistant plants and best and worst plants for Japanese beetles to learn which plants might work best for controlling all of these pests. For rabbits, pick plants like forsythia, lilac bushes, zinnias, daffodils, lavender, and snapdragons. Your rabbit population might be reduced as a result of this. Although planting these plants in your garden may make it less enticing than another, this is not a guarantee because hungry rabbits will consume practically anything. Additional plants that rabbits don’t like include:
