Holes in Evening Primrose Flower

Evening primrose flowers are known for their beauty and delicate petals. This is what makes them one of my favorite flowers. However, these delicate petals can also be easily damaged. One of the most common problems that I see with evening primrose flowers is holes in the petals.

Luckily, I’m well-versed in this area as I’ve had to deal with this issue many times before. There are a few things that you can do in order to fix this problem. Let’s jump in!

Why Are There Holes in My Evening Primrose?

Pests are usually the cause of holes in evening primrose flowers. The most common culprits are aphids and beetles, but larger pests like slugs can also cause damage. These pests are attracted to the taste of the flower’s petals and leaves. As they feed, they leave behind small holes.

You can find out what kind of pests are causing damage to your evening primrose by taking a close look at the holes. If the holes are small and round, then it’s likely that aphids are to blame. If the holes are larger and jagged, then beetles are probably the cause. Slugs will leave behind a slimy trail in addition to large holes.

These pests are known to hide, so look for them in the crevices of leaves and around the base of the plant. You can also check for signs of damage at night when they are most active.

How to Remove Pests from Evening Primrose?

Big pests like slugs can be removed by hand. For smaller pests, you’ll need to use a pesticide. I recommend using an organic pesticide so that you don’t damage the flower further.

My favorite type of pesticide for primroses is Neem oil, which is a natural pesticide made from the Neem tree. This oil will disrupt the life cycle of the pests and prevent them from reproducing. It’s also safe for humans and animals.

To use this pesticide, mix one tablespoon of neem oil with one cup of water. Then, use a spray bottle to apply the mixture to the affected areas. Coat all areas of the plant, including the undersides of leaves. Be sure to reapply every few days until the pests are gone.

You can also try using a diatomaceous earth pesticide. This is a type of powder made from fossilized algae that’s deadly to small insects. It works by puncturing their exoskeletons, causing them to dehydrate and die.

How to Stop Pests From Returning?

To keep pests from returning, you’ll need to take preventive measures. The best way to do this is to keep your evening primrose plants healthy. This will make them less attractive to pests.

Next, keep your garden clean. This means removing debris and dead leaves from the area. Without places to hide, pests will be less likely to stay in your garden and will be more likely to move on.

Applying neem oil as a preventative measure can also help to keep pests away. As soon as any pest lands on your plant, they’ll be coated in the oil and will be less likely to return.

Finally, you should inspect your evening primrose plants regularly for signs of damage. Be sure to check the undersides of the leaves and around the base of the plant. By catching pests early, you can prevent them from doing serious damage to your evening primrose flowers.

Should I Prune Evening Primrose with Holes?

There is no need to prune evening primrose with holes. Pruning will only cause more stress to the plant and can open up new areas for pests to enter. The good news is that tackling the pest issue will also fix the hole problem.

Once you’ve removed all of the pests from your evening primrose, the holes should begin to disappear on their own. The plant will produce new growth and the damaged areas will eventually be replaced.

If you must prune, only remove the damaged parts of the plant. Be sure to sterilize your pruning tools before and after use to prevent the spread of diseases.


In conclusion, holes in evening primrose flowers are typically caused by pests. The most common culprits are aphids, beetles, and slugs. To remove these pests, you’ll need to use a pesticide. I recommend using neem oil or diatomaceous earth for the best results.

To keep pests from returning, you should take preventive measures such as keeping your garden clean and inspecting your plants regularly. Additionally, applying neem oil to your evening primrose as a preventative measure can help to keep pests away.
