Why Do My Roses Have Holes in the Leaves?
You might be wondering why your pretty rose bushes have holes in their leaves.
There are a few reasons this could be happening. Bugs, diseases, not enough nutrients, and the environment can all cause holes in rose bush leaves.
You need to figure out what’s causing the problem, to be able to fix it. Let’s look at each of these reasons more closely.
Common Pests Causing Holes in Rose Leaves
One main reason for holes in rose leaves is insect Infestation. Some pests like to eat rose bushes, making holes in the leaves. Let’s talk more about these insects and the damage they can do.
- Cutter Bees
Cutter bees make half-moon-shaped cuts in rose leaves. If you don’t stop them, they can harm your rose bushes. To get rid of cutter bees, you can use a bug spray made for them.
- Caterpillars
Caterpillars are another bug that can cause big problems for your roses. They usually leave random spots or eat the whole leaf.
To stop them from causing further damage, pick caterpillars off the leaves and put them in water.
This works well as a good control method. Or you can use Bacillus thuringiensis, a natural way to get rid of caterpillars that’s safe for the environment.
- Rose Slugs
Rose slugs are pests that come out at night and eat rose leaves. They make big holes or eat the whole leaf, leaving just the middle part.
Soapy bug spray and plant oil work well to control them. You can also use bug sprays meant for home use, like acephate, bifenthrin, cyfluthrin, lambda-cyhalothrin, permethrin, and spinosad on them.
- Scale Insects, Aphids, and Thrips
Scale bugs, aphids, and thrips are bugs that often damage roses and can make holes in the leaves. Scale bugs look like tiny scales on rose stems, sucking out food and leaving the leaves weak.
Aphids and thrips can also cause harm when there are a lot of them. You can spray aphids with water or use plant oil to stop scale bugs.

- Slimy Bugs and Hard-Shelled Bugs
Slugs and snails are slimy pests that can make your pretty rose leaves full of holes. These pests like dark and wet places and usually eat leaves at night.
To protect your roses from them, you can make a barrier with crushed eggshells or diatomaceous earth. These things stop slugs and snails from crawling over them, so your rose leaves stay safe.
Bugs like beetles can also make holes in rose leaves. Japanese beetles, in particular, like soft rose leaves and make round holes.
To deal with this, you can pick off the beetles in the morning when they’re still sleepy. And then put them in soapy water to get rid of them. Or you can use natural neem oil to keep Japanese beetles away from your roses.
- Black Spots and Powdery Mildew
Holes in rose leaves can also happen because of fungal infections like black spots and powdery mildew.
To keep your roses healthy, make sure air can move around them, don’t water them from the top, and keep the leaves dry.
If your roses get a fungus, you can mix baking soda, water, and dish soap on the leaves every one or two weeks. This mix helps get rid of the fungus and makes your roses healthy again.
- Nutrient Deficiencies as a Factor
Not having enough potassium can make small round holes, because potassium helps keep plant tissue strong. Make sure that the soil has enough organic matter and the right pH to stop nutrient problems and keep your roses healthy.
Why is My Rose Leave Yellow
Yellow leaves on rose plants could mean they don’t have enough nutrients, especially nitrogen in the soil. To fix this, you can put decayed plants or balanced plant food near the bottom of the plants.
Always make sure they get enough sunlight and the soil drains well. Taking off yellow leaves often can stop diseases from spreading and keep the plant from getting worse.
Combating Plant Illnesses Caused by Fungus
Chlorosis is when leaves turn yellow because they don’t have enough chlorophyll.
This can make the leaves weak and more likely to get holes. To fix this, make sure your roses get enough nutrients, especially iron.
Put iron chelate in the soil or Use Epsom salt to help with chlorosis and make the leaves healthier.
