Are you waking up to find your beloved hydrangea looking more like a disgruntled feast rather than a garden star? Unfortunately, hydrangeas can often become the prime dining spot for several bothersome pests.
From discoloration and gnawed leaves to drooping flowers, damage signs can reveal a secret battle happening right in your backyard. With a variety of culprits lurking, identifying what is eating your hydrangea is the first step to regain control of your garden’s peace.
What Is Eating My Hydrangea?
The most common pests that could be eating your hydrangea are insects like aphids, hydrangea scale, and caterpillars. You might also see the effects of slugs, snails, or deer, depending on your garden’s location. Aphids are tiny insects that suck sap from the hydrangea leaves, causing yellowing and deformity. Hydrangea scale appears as a white covering on the leaf bottom and stems, and the insect feeds on the plant’s sap. Caterpillars can cause significant damage as they eat the leaves.

|Damage||Root damage leading to stunted growth and nutrient deficiency.|
|Control||Implement regular inspections, use insecticidal soap or neem oil, attract beneficial insects, and remove affected plant parts.|
Aphids and Hydrangeas
Aphids, small sap-sucking insects, commonly infest hydrangeas. They are usually found on the undersides of leaves or on young shoots, where they pierce the plant tissues to feed on the sap. This triggers a variety of detrimental effects, including leaf yellowing, curling, wilting, and decreased growth rates. If left unchecked, severe aphid infestations can lead to the death of your hydrangea.
Solutions to Aphid Infestations
Good news is, managing aphid infestations can be quite straightforward. One simple way is to regularly hose down your hydrangeas with a strong stream of water to physically dislodge the aphids. For more heavy infestations, you may need to use insecticidal soaps or horticultural oils. These are typically considered safe for your plants and beneficial bugs, while deadly to aphids. It’s always good practice to regularly monitor your hydrangeas for aphid activity to catch infestations early on. With these methods, aphids can be effectively controlled.

|Control||Implement physical barriers, such as copper tape, and organic solutions like beer traps, to deter slugs from devouring hydrangeas.|
Damage by Slugs on Hydrangeas
Slugs are a common garden pest that can eat hydrangea leaves, especially in wet and humid conditions. They typically feed on these plants during the night, leaving behind irregular, ragged holes in the leaves, often along the leaf veins.
Solution for Slug Infestation
There are several methods you can use to control slugs. Firstly, you can handpick them off your hydrangeas during the evening or early morning to physically remove them. Secondly, using slug pellets that contain iron phosphate can be an effective method to kill slugs without harming other wildlife.
Natural Slug Control Methods
For a more natural approach, you could use beer traps, which attract and drown slugs. Alternatively, planting things that slugs don’t like, such as rosemary or lavender, near your hydrangeas could help repel them. Also, removing garden debris and reconsidering your watering habits (water in the morning so the soil dries out during the day) can help to create an environment that is less appealing to slugs.

|Control||Implement physical barriers such as copper tape, create a beer trap, apply organic snail repellents, and maintain a clean garden.|
Effect of Snails on Hydrangeas:
Snails are common pests that harm hydrangeas. They feed on the tender parts of the plant, usually the foliage, resulting in large, irregular holes. These pests are nocturnal and prefer damp conditions, which is why they are often found hiding under leaves during the daytime. Their feeding can severely damage or even kill the plant if left unchecked.
Controlling Snails on Hydrangeas:
To deal with snails, you can utilize slug and snail baits that are available in garden supply stores. Scatter the bait around the hydrangeas, especially in the evening when these pests are most active. An alternative organic method is to set traps using beer or yeast water in a shallow container. The smell attracts snails and they will fall into the trap.
For long-term preventative measures, consider incorporating plants into your garden that are known to repel snails, such as lavender, rosemary, or sage. Additionally, try to keep the area around your hydrangeas clean and free of debris where snails might hide. Regularly inspect your plants for signs of these pests and remove them manually if present.
In severe cases, consider consulting with a professional pest control or gardening service to properly treat your hydrangeas and ensure their health and longevity.

Effects of Deer on Hydrangea: Deer are known to wreak havoc on gardens. They have a particular taste for hydrangeas, consuming the lush leaves and vibrant blooms of the plant. They are capable of causing extensive damage, oftentimes, eating away the entire plant including the buds, leaves, and stems.
Solutions: The first method to deter deer is to use repellents. These can be either odor-based or taste-based and should be applied following the package’s instructions. Fencing is another solution. A high fence around your garden will prevent deer from reaching your hydrangeas. Install motion sensors that trigger lights or sprinkler systems, frighten deer and discourage them from coming into your yard. Lastly, you can also opt for deer-resistant plants in your garden. These include certain types of shrubs, herbs, and flowers that deer typically avoid.

– Introduce natural predators of rabbits, such as owls or foxes, to the area.
– Regularly inspect the plants for any signs of damage and take immediate action if rabbits are present.
Rabbits as Pests
Rabbits are known to be a common pest for hydrangeas. These furry creatures enjoy nibbling on the tender shoots, leaves, and buds of the plant. While the occasional nibble won’t significantly harm your hydrangea, continuous feeding can lead to stunted growth and reduced blooming.
Firstly, fencing your garden or the plants directly could be an effective way to deter rabbits. The use of repellents, both commercial and homemade, can also help. These usually need to be reapplied after rain. Another approach is installing motion detection sprinklers that scare away the rabbits. In some cases, introducing plants that rabbits dislike, around your hydrangeas, can serve as a natural deterrent. Ultimately, it’s all about creating an environment that is unwelcoming to rabbits while preserving the beauty and health of your hydrangeas.

Damage to Hydrangeas by Squirrels
Squirrels can cause significant damage to your hydrangeas. They are known to eat the bark, leaves, and flowers of the plant, which can lead to poor growth and loss of blooms. Their feeding activities can lead to structural damage as they strip off the bark, leaving the plant exposed to diseases and weather conditions. Other than eating, they may also dig up the roots when burying their food, leading to further harm.
Solutions to Squirrel Infestation
The best defense against squirrels is prevention. Using a good quality squirrel repellent sprayed onto the plants can deter them from feeding. You can also consider netting your hydrangeas to physically prevent these creatures from reaching the plants. Adding squirrel feeders to your garden away from your plants may attract the squirrels to a different location. Alternatively, if the squirrels are a persistent problem, you may want to hire a professional pest control service. Be sure the pest control methods you employ are humane and comply with local wildlife laws.

Hydrangeas can fall prey to various pests, including Hydrangea Scale, Aphids, Japanese Beetles, and Slugs. Signs of damage include holes or bites in the leaves, discoloration, wilted flowers or leaves, and a generally weakened appearance.
Hydrangea Scale are tiny insects that suck the sap out of the plant, causing yellowing and wilting. Using a systemic insecticide applied in the early summer when the first signs of infestation occur, can be effective in controlling them.
Aphids also feed on the sap, leaving a sticky residue and causing the leaves to turn yellow and drop off. A good way to get rid of them is by using insecticidal soap or neem oil.
Japanese Beetles are notorious for munching on hydrangea leaves, leaving them skeletonized. Hand-picking them off or using a beetle trap can help in managing beetle populations.
Finally, Slugs can be a problem, chewing holes in the leaves usually at night. You can hand pick them at dusk or trap them using beer traps or slug pellets. Regularly checking for and removing these pests will also help to maintain the health of your hydrangeas.

|Control||Implement a combination of physical barriers (e.g. fences) and natural deterrents (e.g. predator urine) to protect hydrangeas from pests.|
Damages Caused by Mice
Mice can be a nuisance to your hydrangeas. They are capable of devouring the buds, stems, leaves, and even the roots of your plants, causing significant damage. This consumption negatively affects the plant’s growth and overall health, as it reduces the plant’s ability to photosynthesize and absorb nutrients.
Prevention and Control
To protect your hydrangeas from mice, you could use various methods. Using a rodent repellent, which can be found in gardening stores, is one option. These repellents, which are usually non-toxic, tend to deter mice from gnawing on your hydrangeas. Additionally, you could use a physical barrier like a wire mesh or fence around the plant.
Regularly clearing garden debris, which can serve as a hiding place for mice, can also help prevent an infestation. If there’s already an infestation, consider contacting a professional pest control service.
