Aphids love to prey on the queen of flowers – the Rose. This article explains how to deal with aphids infesting roses and how to prevent them from returning in the future.
You’re already anticipating your roses’ spectacular colors and distinctive perfume when spring arrives? A nasty surprise awaits you as the first flower buds appear: leaves that are deformed, shiny, and stick to your hands.
These are common aphid infestation symptoms, as aphids may do a lot of damage to flowers and foliage. Aphids feed on the sweet phloem sap in roses, stunting their growth. Aphid infestations that are too severe can potentially kill the bud. You can also check out our article on how to get rid of aphids on indoor house plants.
We’ll show you how to spot an aphid infestation on roses, how to treat it effectively while minimizing damage to the environment, and how to avoid further infestation. The use of environmentally friendly approaches to reduce the aphid infestation on roses is a viable option in addition to the different home remedies now available.

Identify Aphids Infesting Your Rose Garden
If you have a few aphids on your roses, they will quickly multiply and spread, so keep an eye out for any signs of an aphid infestation. But how do you know if you have an infestation of these nasty pests?
Aphids are frequently visible with the naked eye if you look closely at the tips of your plants or the attachments on your flowers. The aphids might be green, black, red, or white and are a few millimeters in length. In most cases, the green-colored rose aphid (Macrosiphum roseae) will be seen in gardens full of blooming roses.
Deformed and curled leaves at the shoot tip, as well as drooping flower buds, are signs of aphid infestation. There are times when plants reject flower buds because of an infection. Aphids sucking action on the plant causes a considerable localized water loss, which results in flower buds and stem tips drooping downward.
The sticky honeydew that glitters in the sun typically covers the leaves under an aphid colony. Everything that’s stuck to the leaves should be an energy-rich substance that’s circulating throughout the plant and feeding the cells.
A blackish sooty mold likes to deposit on the leaves because of the sugar, and this might damage the plant even more by preventing photosynthesis.
Aphid infestation is indicated by the increasing presence of ants on a plant. Ants consume aphid honeydew, which is a sugary secretion of these pests. As a result, ants shield aphids from predators and thus encourage them to consume more plant sap. Ants, in this way, facilitate an infestation of these small pests.
How can I recognize aphids on my roses?
Here are some pointers to quickly identify if aphids have infested your beautiful rose garden.
- Insects are a few millimeters in size, mainly green in color.
- Can be noticed at the tips of the stems and around the buds.
- Leaf deformities, including twisted and bent edges.
- Buds and shoots dangling downward.
- Honeydew-damaged leaves have become slick and glossy.
- Leaves might develop a dark sooty mould from time to time.
- More ants are appearing on and around the rose plants.
How to Get Rid of Aphids from Rose Garden
Aphid infestations in roses may be devastating, so what should you do? Stopping the aphids from feeding as soon as possible and then getting rid of them should be the goal.
Chemical vs Natural Treatments
Organic and Synthetic treatments are the two main types of plant protection treatments available. It is not recommended to use synthetic chemical agents in home gardens or in the home because they could harm beneficial insects. When possible, we suggest using biological measures instead of chemical ones.
Organic Neem Treatment to control Aphids
Neem-based treatments, derived from the seeds of the neem tree, are a highly effective and safe alternative. These have oil in them that’s especially good in keeping aphids at bay. The aphids sucking on the plant absorb the neem oil’s herbal active component.
After a few hours, the insects no longer have an appetite for feeding and stop sucking. The active element also stops the aphids from growing and developing, so they perish.
Due to the fact that the active ingredient is dispersed throughout the plant, the systemic action affects even hidden aphids. Organic Neem-based treatments get their power from neem oil, which has proven to be quite powerful in controlling pests. It’s a natural way to keep aphids under control and thus protecting your roses.
Spray the neem oil based product on the infected plant after mixing it with water in a spray bottle. Twelve roses can be treated with three milliliters of pest-free solution diluted in two liters of water.
#Tip: Organic Neem Pest Control is safe for bees, too. Correct application is critical with any plant protection agent, of course.
#Tip: If a neem-based product is applied, you should make sure that cats keep some distance. While there is no warning from the Federal Office of Consumer Protection and Food Safety, some studies indicate that cats may be allergic to neem oil.
Organic Neem Aphid Pest Control Process
- Apply in the morning or evening as soon as an infestation is discovered.
- Put on safety gear and pay attention to the directions on the packaging.
- To treat approximately 12 roses, use 3 ml of Neem-based product with 2 liters of water (do not prepare more spray than necessary).
- Spray the solution on the afflicted plant.
- Do not dispose of any leftovers in the sewer or with waste water.
- After a period of severe rain, repeat the process again.
Home Remedies to Control Aphids Infesting Roses
If your roses only have a minor aphid infestation, you can employ natural methods to get rid of the pesky insects. Here are the top two home remedies.
Using Diluted Soap
Soft soap foam is a common home treatment for aphid infestations on roses. For this, use a fragrance-free pure curd soap or soft soap to create sudsy lather. In order to make liquid soap, use a 200-milliliter soap to 1 liter water ratio. Nevertheless, other detergents are unsuitable due to the risk of harming plants.
Using a spray bottle, the soap foam is sprayed all over the affected region. This results in a lye film that suffocates the aphids. Spraying the soapy residue several times a day will have the desired effect. You can stop treating your roses once you can no longer see aphids on them.
Using Nettle Decoction
Nettles are not only unpleasant for humans, but they also aid in the control of rose lice. You can easily prepare the nettle concoction at home by following the process described below.
In a kettle with five liters of boiling water, soak 500 grams of fresh, green nettles. The mixture should be swirled many times with a wooden spoon before being allowed to cool and infuse for 24 hours.
In this technique, the active compounds in nettles, such as formic acid, are extracted from the leaves. The decoction can then be filtered through a small sieve to avoid clogging the spray bottle later on. Using a spray bottle, spray the undiluted decoction onto the affected regions.
This treatment should be repeated several times per day until your roses are no longer plagued with aphids. To avoid scorching the leaves on days with strong sunlight, delay treatments until the early morning or evening hours.
Nettle decoction not only kills aphids but also includes active components such as silicic acid, which strengthens your plant.
#Tip: Nettle leaves that have been filtered out can be dried and used as a mulching layer in your rose bed. As described in this post on nettle liquid manure, the residual nettle broth can be blended with water in a 1:20 ratio and used as a liquid fertilizer.
Preventing Aphids on Roses
When dealing with the aphid pest, the same rule always applies: “prevention is better than cure“. Aphids thrive on weakening plants, which explains why large infestations are more common. Aphids prefer weak plants, which is why strengthening your roses can help you avoid aphid infestations.
Proper rose care is just as vital as an adequate supply of nutrients in this case. When fertilizing your roses, make sure you have a sufficient supply of potassium and a low amount of nitrogen. It is also critical to maintaining an adequate amount of magnesium. By using an organic rose fertilizer, for example, provides an adequate supply of nutrients for your roses.
How about a mixed culture rose bed instead of a pure rose bed? Plants that have essential scents, such as savory, onions, and notably lavender, not only repel pests but also look nice next to roses. Mixing roses with lavender, for example, can help keep pests away from your roses.
Beneficial insects that eat aphids, like ladybugs, ichneumon wasps, and aphid midges, can also help avoid aphid infestations on your roses. Building nesting boxes as well as making your garden beneficial insect friendly are two ways to encourage beneficial insects. Beneficial insects can also be acquired and deliberately established, which works particularly well inside or in greenhouses.
Furthermore, aphids are not really good at clinging to their host plant. If you only have a minor infestation on your plants, you should use a strong stream of water to rid the shoots of the aphids. Infestations are common in the spring and in early summer, therefore beginning in April, it is recommended that you inspect your plants on a regular basis.
What is the best way to prevent aphids on my roses?
- Fertilize your roses as needed with a good Organic Rose Fertilizer, which contains potassium and magnesium.
- Using cultivation in conjunction with fragrant plants like lavender or savory.
- Encourage beneficial insects to visit your garden or use them sparingly.
- Using a water jet, spray lightly infested shoots.
