Holes in Wisteria Leaves: Reasons and Solutions

Do you have a wisteria plant in your garden? If so, you may have noticed that the leaves have holes in them. This can be quite concerning, but don’t worry – we’re here to help! In this blog post, we will discuss the reasons why wisteria leaves may have holes in them and how to fix the problem.

Why Are There Holes in My Wisteria Leaves?

There are holes in your wisteria leaves because a pest is eating them. The most likely culprits are caterpillars, beetles, aphids, mealy flats, and the wisteria borer.

These pests are attracted to wisteria plants because they offer a good food source. Wisteria leaves are high in protein and nutrients, which makes them an ideal target for pests.

Take a closer look at your wisteria leaves. If you see any of these pests, you’ll know that’s the cause of the holes in your leaves. You may need to inspect them early in the morning or late at night, as some of these pests are more active during those times.

The wisteria borer is an infamous pest that is known for causing damage to wisteria plants. The larvae of this pest bore into the stems and branches of the plant, which can cause the plant to become weak and eventually die.

How to Treat Wisteria Leaves with Holes?

To treat wisteria leaves with holes, you’ll need to remove the pests that are causing the damage. The best way to do this is to handpick them off of the plant. You can also use a garden hose to blast them off.

If you have a severe infestation, you may need to use an insecticide. Be sure to choose an insecticide that is specifically labeled for the pest you’re trying to control. For example, if you’re dealing with caterpillars, look for an insecticide that contains Bt (Bacillus thuringiensis).

My favorite method of pest control is to use neem oil (Amazon link), which is a natural and effective way to get rid of pests. You can find neem oil at your local garden center or online.

Simply mix the neem oil with water according to the manufacturer’s instructions and spray it on your wisteria plant. Be sure to thoroughly cover the leaves, stems, and branches. You’ll need to reapply neem oil every few days until the pests are gone.

You can also use other natural methods of pest control, such as diatomaceous earth, essential oils, and ladybugs.

How to Keep Pests Away From Wisteria Leaves?

To prevent holes in wisteria leaves, you’ll need to take steps to keep pests away from your plant. The best way to do this is to keep your plant healthy and strong. A healthy plant is less likely to be damaged by pests.

Be sure to water your wisteria regularly and fertilize it with a high-quality fertilizer. You can also prune your plant to promote new growth.

You can also use pest control methods, such as traps, to keep pests away from your wisteria. For example, you can use yellow sticky traps (Amazon link) to trap aphids. Place the traps near your plant and check them regularly. Remove any trapped pests and dispose of them.

You can also use barriers, such as row covers, to keep pests away from your wisteria. Row covers are placed over plants and secured at the base. This creates a barrier that pests cannot penetrate.

What Else Causes Holes in Wisteria Leaves?

There are other reasons why wisteria leaves may have holes in them, such as:


Holes in wisteria leaves can also be caused by disease. Common diseases that affect wisteria plants include powdery mildew and leaf spot. These diseases can cause discoloration, wilting, and eventually death.

If you suspect that your plant has a disease, use fungi or bacteria-specific fungicide. Be sure to follow the manufacturer’s instructions carefully.

Environmental Damage

Holes in wisteria leaves can also be caused by environmental damage. For example, if your plant is exposed to too much sun or wind, it can cause the leaves to dry out and develop holes.

You can prevent environmental damage by placing your wisteria in a location that receives partial sun and is protected from strong winds.


Wisteria is toxic in most animals, so it’s unlikely that an animal will eat the leaves. However, animals can cause damage to wisteria plants by rubbing against them or digging in the soil around them. Birds, rodents, and deer are common culprits.

To prevent animals from damaging your wisteria, you can use fencing or repellents. Fencing should be at least six feet high and made of sturdy material, such as a chicken wire. You can also use animal repellents, such as mothballs or ammonia-soaked rags.

Should I Prune Wisteria Leaves with Holes?

Pruning is not necessary if your wisteria leaves have holes. However, you may want to prune the plant to encourage new growth and get rid of any leaves with diseases. If you do prune your wisteria, be sure to use sharp, clean pruning shears.

You can also prune your wisteria to shape it. For example, if you want your plant to grow in a certain direction, you can prune it to encourage growth in that direction.


In conclusion, holes in wisteria leaves are usually caused by pests or disease. However, environmental damage and animals can also cause holes. To prevent holes, you’ll need to take steps to keep pests away from your plant and protect it from the environment.

My number one tip is neem oil, which is a natural pesticide that will kill the pests that are causing the holes in your leaves. Simply apply the neem oil to the affected areas and reapply every few days until the pests are gone.
