Roses are an excellent addition to any garden, as there are many varieties and colors available. Unfortunately, gardeners are the only ones attracted to this stunning flower. Aphids are one of the most common garden pests. They eat everything from peppers and potatoes to roses and more.
If you see aphids on your rose buds, you should get rid of them right away to keep your plants healthy and long-lived. Fortunately, there are many tried-and-true methods for getting rid of aphids. Here are some of the most effective ways to get rid of aphids and protect your roses.
Aphids are tiny pests that can do major damage to rose bushes by sucking sap from the plants. An aphid infestation can weaken and even kill rose bushes if left uncontrolled. Getting rid of aphids requires persistence and consistency, but is possible with homemade and natural solutions. This comprehensive guide will provide useful tips and methods for eliminating aphids from roses.
What are Aphids?
Aphids are soft-bodied insects that use their piercing mouthparts to suck sap from the tender shoots buds and leaves of plants. There are around 250 species of aphids that can infest roses. Some of the most common species include the rose aphid, potato aphid, green peach aphid, and melon aphid. Aphids secrete a sticky substance called honeydew that attracts sooty mold fungus. A large infestation can stunt plant growth and lead to deformed buds and foliage.
Signs of an Aphid Infestation
It’s important to regularly inspect rose bushes for early signs of an aphid infestation
- Curled, distorted, or yellowing leaves
- Sticky residue on leaves and canes
- Clusters of small (1-3 mm), soft-bodied insects on new shoots and flower buds
- Ants crawling up and down the rose canes
Ants are often present where aphids are feeding since they feed on the honeydew secretions. Catching an infestation early allows for more effective treatment. Don’t wait until the aphids are widespread.
Effective Ways to Get Rid of Aphids
Spray Down with Water
A strong spray of water can dislodge and kill many aphids. Focus on the undersides of leaves and other areas where the pests gather. Repeat every few days to target newly hatched aphids. The forceful spray also removes honeydew secretions before sooty mold can grow.
Insecticidal Soap
Insecticidal soap sprays are very effective against soft-bodied insects like aphids. The soap penetrates the aphid’s protective outer layer and causes dehydration. Spray liberally on infested areas. Reapply every 5-7 days for 2-3 weeks until aphids are under control. Some brand examples are Safer’s Insecticidal Soap and Garden Safe Insecticidal Soap.
Neem Oil
Neem oil is a botanical insecticide derived from the neem tree. It smothers and kills juvenile aphids on contact. The oil also disrupts the reproduction cycle of adult aphids. Mix neem oil concentrate with water according to label directions and spray thoroughly on affected foliage, stems, and buds every 7-14 days. Neem oil is safe for people, pets, pollinators and plants when used as directed.
Horticultural Oils
Like neem oil, lightweight horticultural oils kill aphids by coating and smothering them. The oils also deter aphids from feeding on plants. Apply horticultural oil sprays every 7-14 days according to product instructions for severe infestations. Oils are very effective against immobile stages like eggs and nymphs. Some examples are SunSpray Ultra-Fine Oil and Bonide All Seasons Horticultural Oil.
Insecticidal Dusts
Powdery insecticidal dust made from diatomaceous earth fossils or mineral silica damages the waxy protective coating on aphids causing dehydration and death. Puff the dust onto dry foliage using a hand duster. The sharp particles cut into soft-bodied insects. Reapply after rain or watering. Some products are Safer Brand Diatomaceous Earth and Garden Safe Multi-Purpose Insect Killer.
Natural Predators
Beneficial insects like ladybugs, lacewings, hoverflies, and minute pirate bugs are predators of aphids. They can be purchased online and released onto infested roses. Or plant pollen and nectar sources like daisies, dill, and cosmos to attract them to the garden. The voracious predators provide natural aphid control.
Fungal Insecticide
Beauveria bassiana is a fungus that infects and kills many types of insects including aphids. Fungal spores penetrate the aphid body and multiply causing death within a few days. Commercial strains are available as liquid concentrates or powder formulations. Foliar application provides contact and residual control of aphids. Some products containing Beauveria bassiana are BotaniGard ES and Mycotrol ESO.
Remove Ants
Eliminating ants that feed on honeydew secretions can significantly reduce aphid numbers. Apply sticky barrier tapes around rose canes to prevent ants from climbing up. Or sprinkle ant baits or diatomaceous earth in problem areas. Removing this food source causes aphid colonies to decline.
Strong Water Stream
A daily strong stream of water can help wash away aphid populations before they multiply. Focus the pressure on the undersides of leaves and new shoots where aphids gather. The constant force keeps populations low and prevents future outbreaks.
Reflective Mulch
Spreading reflective mulch like aluminum foil around rose bushes can deter aphids from landing and colonizing the plants. The reflective surface confuses aphids and interferes with their reproduction. Replace the foil after several months as needed.
Remove Infested Growth
Prune and destroy any leaves, stems, or flower buds that are heavily infested with aphids. This eliminates populations and prevents them from spreading to healthy plant tissue. Be sure to dispose of the cuttings promptly.
Organic and Natural Solutions
Botanical insecticides like neem oil, essential oils, or pyrethrins derived from chrysanthemum flowers can control aphid populations without synthetic chemicals. Always follow label directions carefully. Insecticidal soap and horticultural oil sprays are also organic options for eliminating aphids on contact.
Preventing Future Aphid Infestations
Here are some tips to help prevent and control future aphid problems:
- Monitor roses frequently for signs of pests
- Remove and destroy any heavily infested parts immediately
- Use a strong spray of water to regularly dislodge aphids
- Release beneficial predators like ladybugs and lacewings
- Apply preventative sprays of insecticidal soap or neem oil early in the season
- Avoid over-fertilizing roses which causes excessive new growth that attracts aphids
- Grow alyssum, dill, fennel, and other small flowers to support beneficial insects
- Wrap trees, posts, or fences near roses with sticky tape barriers
- Maintain vigor through proper watering, pruning, and fertilization
When to Seek Professional Help
For severe infestations that persist after repeated attempts at treatment, contacting a professional may be warranted. They have access to more potent insecticides that may be necessary to completely rid roses of heavily established aphid populations. Professionals can also identify the specific species to tailor the treatment method. Seeing the extent of the damage, they will know if the roses can recover or need replacing.
Left unchecked, sap-sucking aphids can destroy beautiful rose plants. But with persistence and the right control methods, aphids can be managed and roses protected. Start at the first signs of infestation for best results. Combining multiple strategies often leads to complete control. With prevention and early intervention, vibrant, aphid-free rose bushes can be maintained to enjoy their beauty and fragrance all season.
What Are Aphids?
Aphids are a common garden pest, since theyre attracted to a wide range of flowers and vegetables. Aphids are generally the size of a flax seed and are typically green and black. These tiny bugs are usually found in groups on a plant’s stem, leaves, or both. However, they aren’t always easy to spot. If you cant locate these insects, look for the following signs of an aphid infestation:
- A saliva-like substance that is secreted by aphids, called “honeydew.”
- An unsightly, sooty mold, encouraged by the presence of honeydew.
- A huge group of ants on your rose buds because they like honeydew.
- Your rose bud leaves may begin to wilt or curl.
Why Are Aphids Harmful for Roses?
Aphids are harmful to roses, and a wide range of other popular garden plants, for many reasons. Aphids eat the sap in plant stems and leaves, which makes the plant weak and can stop its growth. Aphids not only eat your beautiful roses, but they also put saliva on the leaves, which can make people sick. As if these things weren’t bad enough for your rose buds, the sooty mold that aphids make from their honeydew can stop plants from taking in light and making food.
