If you’re like most gardeners, you enjoy spending time outdoors surrounded by beautiful plants. One of the most common plants grown in gardens is geranium. While these plants are generally easy to care for, there can be times when they experience problems.

One such problem is holes that appear in the leaves. In this article, we will explore what causes these holes and how you can treat them.

Why Are There Holes in Geranium Leaves?

Pests are the primary cause of holes in geranium leaves. The most common pests that attack these plants are aphids, slugs, and caterpillars. These pests can cause damage by eating the leaves completely or by puncturing them as they feed.

Take a closer look at the leaves to see if you can identify which pest is causing the problem. Aphids are small, soft-bodied insects that congregate in large numbers on the undersides of leaves. Slugs are slimy creatures that leave a trail of slime as they move. Caterpillars are the larvae of moths and butterflies and can vary greatly in size and appearance.

In reality, there are dozens of pests that can cause holes in geranium leaves. Once you’ve identified the pest, you can take steps to control it and prevent further damage.

How to Remove Pests from Geranium Flowers?

The best way to remove larger pests from geranium flowers is to physically remove them by hand. This can be done using a cotton swab or a soft brush. For larger caterpillars, you may need to use tweezers.

Smaller pests can be controlled using a variety of methods. One option is to spray the plants with water to knock the pests off. You can also use insecticidal soap or neem oil. These products will disrupt the lifecycle of the pests and prevent them from causing further damage.

Diatomaceous earth can also be used to control pests. This is a powder that is made from fossilized diatoms. It works by puncturing the exoskeletons of insects and causing them to dehydrate and die.

Preventing Pests on Geranium Flowers

Once you have gotten rid of the pests, you will need to take steps to prevent them from returning. The best way to do this is to keep your plants healthy. Healthy plants are better able to resist pests and disease.

Start by ensuring that your plants are getting enough water. They should be watered deeply and allowed to dry out between waterings. Overwatering can lead to problems such as root rot, which makes plants more susceptible to pests and disease.

In addition to keeping your plants healthy, you can also take steps to deter pests. One way to do this is to remove any debris or mulch from around the base of the plant. This will eliminate hiding places for pests. You can also use yellow sticky traps to control flying pests such as aphids and whiteflies.

Beneficial insects can also be used to control pests. These include ladybugs, lacewings, and parasitic wasps. These insects feed on the pests that damage plants, helping to keep populations in check.

By following these tips, you can eliminate the holes in your geranium leaves and prevent them from returning. With a little effort, you can keep your plants healthy and beautiful.

What Else Could Cause Geranium Holes?

There are a few other things that can cause holes in geranium leaves:

Disease

Certain diseases can also cause holes in the leaves of geranium plants. These include bacterial leaf spots and fungal diseases such as powdery mildew. These diseases thrive in humid conditions, so be sure to water your plants from below to prevent them.

Applying a fungicide can help to control fungal diseases and stop them from spreading. Bacterial leaf spots can be controlled by removing affected leaves and disposing of them properly.

Physical Damage

Geranium leaves can also be damaged by physical means. This can happen if you accidentally brush up against the leaves or if they are blown around in strong winds. The best way to prevent this type of damage is to provide support for the plant so that the leaves are not blown around.

Animals

Sometimes, animals can cause damage to geranium plants. While deer dislike eating geranium, rabbits and groundhogs will often nibble on the leaves. If you suspect that an animal is damaging your plants, you can try using a fence to keep them out.

Should Pest-Damaged Geraniums Be Pruned?

I only recommend pruning your geraniums if the damage is extensive. If only a few leaves are affected, it’s best to leave them be. Pruning can cause stress to the plant, which can make it more susceptible to disease and pests.

It can also be helpful to prune geraniums if the plant is infected with a fungal disease. Removing the leaves that are affected can help to stop the disease from spreading. If you do decides to prune your geraniums, be sure to sterilize your pruning tools before and after use.
