What to do against aphids on roses? Effective and environmentally friendly solutions

Aphids on your roses can be a frustrating challenge, but fortunately, there are several natural and effective ways to combat these unwanted visitors. In this blog, you will discover what you can do to prevent and control aphids on roses without using harmful chemicals.

What are aphids and why do they appear?

Aphids are small, soft insects that feed on the sap of plants. They mainly appear in spring and summer, when the weather gets warmer. While a small amount of aphids is not a problem, a large infestation can weaken your roses.

1. Remove aphids with water and your hands

A simple but effective method is to spray aphids off your roses with water. Use a strong water jet for this. If you prefer not to waste water, you can also gently wipe the aphids away with your hands.

2. Diatomaceous earth as a natural barrier

Diatomaceous earth is a natural powder containing microscopically sharp particles. These particles damage the exoskeleton of aphids, causing them to dry out. Sprinkle a thin layer of diatomaceous earth on and around your roses for effective protection.

How I fight aphids

I personally use water, diatomaceous earth, and my hands to combat aphids. If there are only a few, I just leave them alone. 

3. Mixture of water and green soap

A classic among natural pesticides is a mixture of water and green soap. This mixture clogs the breathing openings of aphids, causing them to die. Mix 20 ml of green soap per liter of water and spray this on the affected leaves.

4. Plant garlic near roses

Garlic contains sulfur and other substances that have a repellent smell for aphids. Plant garlic among your rose bushes to deter aphids.

5. Attract natural enemies like ladybugs

Aphids have natural enemies like ladybugs and their larvae. By making your garden attractive to these beneficial insects, such as with insect hotels, you help nature along. We offer these insect hotels through Ons Tweede Thuis, a social workplace.

6. Attract birds with nest boxes

Birds such as sparrows, blue tits, and robins love to eat aphids. Place nest boxes in your garden to attract these birds. Start early so they have a permanent spot in your garden next year.

7. Mealworms and seeds to attract birds

Want to attract birds quickly? Place dishes with mealworms near your roses. This attracts small birds that love aphids. Be careful not to attract large birds like crows with this.

8. Don't worry too much

A tip from an experienced grower: don't worry too much about a little aphids. Within a few weeks, natural enemies like ladybugs and their larvae will appear. They will clean up the aphids for you. I've already spotted several ladybugs among the roses. 

Conclusion

Aphids on roses are annoying, but with these natural methods, you can effectively combat them without burdening your garden with chemical pesticides. Do you have a golden tip for fighting aphids? Let us know in the comments!
