What Is Eating My Hydrangea

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.

– Aphids

Description Tiny, soft-bodied insects with pear-shaped bodies in various colors, often found clustered on new growth of plants, causing leaf curling and stunted growth.
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.

– Slugs

Description Slimy, nocturnal pests with voracious appetites that leave irregular holes and silvery trails on hydrangea leaves.
Damage Chewed leaves and flowers, slimy trail.
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.

– Snails

Description Small, slimy mollusks with a soft body, a single foot, and a hard shell, known for devouring hydrangea leaves.
Damage Leaves with irregular holes and chewed edges.
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.

– Caterpillars

Description Small, voracious, green or brown pests with multiple legs and a habit of devouring hydrangea leaves.
Damage Devouring leaves and flowers, leading to defoliation and diminished plant health.
Control Implement regular inspection and removal, use insecticides or organic controls like neem oil or Bacillus thuringiensis (BT), and encourage natural predators.

Caterpillars, such as hydrangea leaftiers, can cause significant damage to your hydrangeas. These pests are primarily leaf-eaters. They chew on the leaves creating unsightly holes and can cause a significant amount of defoliation if the infestation is severe. impact of caterpillars on hydrangeas

Use a multi-tiered approach to manage caterpillars. Firstly, you can physically remove the caterpillars when you see them. Secondly, consider applying a caterpillar specific insecticide like Bt (Bacillus thuringiensis) which is organic and safe. Regularly check your plants for signs of these pests and take action promptly when noticed.
