Garden Guides, How to Get Rid of Aphids Without Harming Flowers

How to Get Rid of Aphids Without Harming Flowers

21 September, 2017

Aphids are tiny, lime-green, pear-shaped pests that appear in the garden in the early summer. Sucking the juice from tender new shoots, aphids are among the most destructive garden pests outside of the tropics, attacking everything from roses to potatoes to pine trees. Once aphids have begun to colonize a plant, quick action must be taken or a colony can rapidly evolve into a swarm capable of destroying your entire garden.

Spray infected plants with the garden hose. The pressure from the water will knock the insects off the foliage and wash them away. Once the aphids have been physically removed from the plant, it is unlikely they will attempt to recolonize it. Take care not to use too much water pressure so you don’t harm the flowers.

Apply insecticidal soap following the manufacturer’s instructions.

Make your own anti-aphid soap if you cannot find it at the store or if the price is off-putting. Combine 2 tsp. of liquid dish soap, 1 cup of vegetable oil and 2 cups of water. Stir the ingredients until well blended and then transfer the solution to a plastic spray bottle. Use the soap to thoroughly coat the foliage of any affected plants, being sure to spray the bottoms of the leaves as well as the tops.

Plant marigolds near your other flowers to encourage the growth of beneficial insects such as ladybugs or lacewings. If you can’t seem to attract them, purchase them from a garden center or over the Internet and release them into your garden.

Sprinkle diatomaceous earth over infected plants. The abrasive white powder is nontoxic and safe for people and pets, but the sharp edges created by the fossilized remains can easily shred the aphid’s exoskeleton.

Plant garlic, chives or onions near the flower beds. The aroma is a natural repellent for aphids and other destructive insects. For the greatest effectiveness, these plants should be placed near the flowers early in the spring, prior to the first aphid invasion.

Here in Southern California with our mild and ideal climate conditions, there are still pests and sicknesses that can ail plants. Thankfully, aphids are one of the few pests that disturb my plants. They love showing up on my hibiscus and rosebuds, much to my dismay.

The aphids I’ve seen around here are green, but they can also be white, orange, black, yellow and grey. They like hanging out on the buds of my mini roses and hibiscus flowers. Aphids also can be found under leaves, so don’t forget to check places where you can’t see them.

What are aphids?

Aphids are tiny bugs that love to feed on plants. Aphids love to feed off of the sugary liquid that comes from plant flowers and leaves where the nutrients are located. Aphids will also attack houseplants if they find a way indoors.

If these pests are left alone, they repopulate quickly, and can swiftly become an infestation issue. Here are some more facts about aphids:

  • Aphids can live a several weeks up to several months.
  • Females can reproduce asexually (without males). This only happens in the springtime. During the fall they produce babies sexually.
  • Stinging wasps, ladybugs, lacewings, pirate bugs, crab spiders, and big-eyed bugs are great to have around since they like to eat aphids.
  • Aphid feed off plants during the daytime and nighttime.
  • These bugs go through three life stages: egg, nymph, and adult.
  • Some aphids can make female soldiers. The reason these aphids exist are to watch over and protect their mother.
  • Aphids are very small and grow from 0.04 to 0.39 inches long.
  • Aphids feed on plants by sucking up sap from leaves, stems, roots, and buds. The sticky drops that are left over are called honeydew.
  • Ants love honeydew and will protect aphids so that they can continue to benefit from the honeydew.
  • Sometimes aphids will give birth to winged aphids, but only when these winged pests are needed to find other plants to feed off of.

How to Get Rid of Aphids on Plants

Now that you know a little more about aphids, here are some ways to get rid of them. I am only going to mention organic ways, since I love using natural and homemade methods.

Water and Soap

This is my personal favorite way to eliminate aphids. My husband and I have a water bottle that we use when our cats misbehave. When I spot aphids on my hibiscus and mini roses, I open the water bottle and drip a little dish soap in the bottle. I put the lid back on, shake the bottle, and its ready to kill some aphids!

Remove by Hand

You can also just remove aphids by hand. This can be tricky since they are so small. Put on gardening gloves and you can pinch the aphids off your plants or use a brush to get rid of them this way. You can also prune the branches where the aphids are hanging out and put these in soapy water to kill them.

This method is doable with a few aphids. It may be too time-consuming to remove a bunch by hand though.

Natural Insecticidal Soap

Insecticidal soaps are another option to get rid of aphids. No mixing is required and you can purchase these at your local gardening supply store or online.

Pressure from Water

Water pressure can reduce the aphid population in your garden. Use a water hose to get rid of the pests. Water pressure can hurt younger plants that are still establishing themselves in your garden, but this method works well with older plants that can withstand the pressure.

Animal and Plant Helpers

Bird Bugs

There are certain birds that like to eat aphids. These are chickadees, titmice, and wrens. You may or may not live in an area where these birds live, but if you do, make sure you have plants that these birds love to next in. These include abelia, hydrangea, boxwood, and other small trees and plants.

Insect Helpers

You can also attract insects to your garden that will help keep away aphids. Ladybugs are well known to keep aphids and other pests away from plants. These can be purchased from garden supply stores and online stores. Lacewings and hoverflies can also keep aphids away from your garden.

You want to plant certain plants in your garden to attract these insects. Plant herbs such as oregano, garlic, and catnip to bring in hoverflies. Lacewings and ladybugs love yarrow, mint, clover, fennel, and dill.

Grow Food

Aphids don’t like the smell of garlic and onions. Have these around your plants or grow them where you don’t want to attract aphids.

Aphid Plants

You can also grow certain plants to attract aphids to one area of your garden, away from your prized plants. Grow plants such as asters, dahlias, cosmos, and zinnias that the aphids will happily use as food.

Natural Oils

Neem Oil

Neem oil works in a similar way as water and dish soap. Put some drops of neem oil in water and spray onto plants infested with aphids. Other garden pests will also stay away from neem oil, such as caterpillars, beetles, mealy bugs, leafminers,cabbage worms, and ants.

Essential Oils

Certain essential oils can also work to keep away aphids. Place several drops of clove, thyme, rosemary, and peppermint into a spray bottle with water. Shake this solution and place on plants where aphids are hanging out.

How to Get Rid of Aphids on Roses

Garden pests are a nuisance, and an aphid infestation destroys rose plants if left unchecked. While pollinators, ladybugs, and other insect varieties are useful bugs for the garden, rose aphids are destructive. We’ll show you how to get rid of aphids on roses using natural remedies.

Many species of aphids are members of the superfamily Aphidoidea and are also known as the blackfly and greenfly. These tiny insects are sap suckers, and an infestation destroys an entire plant in no time at all. These insects, in addition to other pests such as spider mites, cause stress to roses, which leads to disease.

Rose aphids spend their time on the undersides of leaves, so they are not always visible. A rose bush that has a black spot from stress and a sticky substance on the stems and rose leaves is a sign that aphids have invaded your garden. This sap, or honeydew, attracts dust to the plant called a sooty mold and resembles powdery mildew.

How to Kill Aphids on Roses Naturally

Organic pest control is essential for keeping aphid populations from destroying your roses. We’ll show you how to get rid of aphids in your garden with natural solutions and how to control aphids by using beneficial insects as natural predators.

Aphids on Roses Home Remedy

The best aphids on roses home remedy without using harsh chemicals is to remove them manually. If you’re not squeamish about dealing with insects on your own, here are a few hands-on techniques to eradicate aphids from your roses.

Manually Removing Aphids

  • Garden gloves
  • Garden hose
  • Plant clipper

Put on garden gloves and pull aphids off your roses by hand. They have soft bodies and crush easily while removing them. If your plants have more than a dozen aphids, use a damp paper towel for quick removal.

Once or twice a day, take the garden hose to your roses as the best way for getting rid of aphids. Spray a forceful stream of water to the underside of leaves to force the pests loose. Doing this combats small infestations on hardy plants. Allow the roses to dry completely between watering to prevent diseases such as rust and blight.

For sections that are heavily infested, perform selective pruning. Use clippers to remove leaves, stems, or parts of the plant that are covered in aphids and discard appropriately. Spray the plant thoroughly with water or a homemade spray for roses after trimming.

How to Get Rid of Aphids on Roses

Soapy water is effective at killing insects. They breathe through small vents in their bodies, and the soap clogs their airway. We’ll show you how to kill aphids on roses using liquid dish soap as a natural bug repellent for plants.

Natural Insecticidal Soap Spray

  • 1 quart of warm water
  • 1 tablespoon of dish soap
  • Cayenne pepper
  • Spray bottle

Pour the warm water into a bottle sprayer, add the dish soap and a pinch of cayenne pepper, and shake the bottle of soap solution gently to mix.

Label the container for continual use. Apply the soap spray liberally to areas of the roses that are affected with aphids. Avoid spraying on beneficial insects because the solution kills them as well.

Make an Essential Oil Blend Aphid Spray

Certain types of essential oils repulse aphids, and these insects stay away from plants sprayed with them. This homemade aphid spray for roses contains a blend of essential oils to keep aphids away.

DIY Aphid Spray

  • Water
  • Glass spray bottle
  • Cedar oil
  • Rosemary oil
  • Clove oil
  • Orange oil

Fill a glass bottle sprayer with water and add one drop of each essential oil. Do not apply essential oils directly to roses without diluting them first to prevent burning the plant. Shake the container well and spray the solution over the surface of the rose bush to kill existing aphids and repel others.

Using Neem Oil to Kill Aphids

Use neem oil for garden and aphid control on roses. This oil is a plant-based oil compound that smothers and kills aphids in just a few hours. This non-toxic oil is sold at garden centers and is not harmful to plants.

Neem Oil Aphid Spray

  • 1 quart of water
  • 1 teaspoon neem oil
  • 1/2 teaspoon dish soap
  • Spray bottle

Fill the spray bottle with water and add the neem oil and dish soap. Shake the bottle gently to mix. Spray the solution on the underside of leaves and other areas of the rose bush infested with aphids.

This spray also kills other pests such as beetles, mealy bugs, and caterpillars. You can kill spider mites on plants and eliminate all kinds of pests that may want to eat your rose bushes. Avoid spraying the solution on beneficial insects since it kills them, too.

Encouraging Beneficial Insects to the Garden

Aphids have natural predators that are useful for keeping infestations under control. After eliminating the aphid problem or before one even begins, introducing these beneficial insects to your garden keeps an aphid population to a minimum.

Aphid Predators

  • Ladybugs
  • Green lacewings
  • Hoverflies

There are a few ways to attract beneficial insects to your rose garden. The best way to attract them is to plant flowers that they enjoy. Ladybugs enjoy sunflowers, geraniums, parsley, Queen Anne’s Lace, and Sweet Alyssum.

Garden supply stores sell these beneficial bugs as egg, larvae, and live specimen forms. The key is to keep a healthy balance by bringing in a modest number to prevent trading one pest for another.

Grow Aromatic Plants to Deter Aphids

Believe it or not, but there are a variety of plant types that aphids cannot stand. Strategically planting these types around your garden keeps aphids from taking an interest in your roses.

Aromatic Plant Deterrent

Any plants that have pungent odors are efficient at keeping aphids at bay. Consider planting onions, chives, garlic, sage, oregano, and ginger root around the vicinity of your roses. Not only do these plants keep the aphids away, but you get the benefits of enjoying the alliums and herbs in savory meals.

How to Protect Your Hibiscus from Aphids? Try These 5 Ace Ways

Aphids can damage the beautiful flowers of hibiscus as well as the plant. Getting rid of them should be your first priority when you notice them. Gardenerdy gives tips to get rid of aphids and bugs on hibiscus.

Aphids can damage the beautiful flowers of hibiscus as well as the plant. Getting rid of them should be your first priority when you notice them. Gardenerdy gives tips to get rid of aphids and bugs on hibiscus.

Hibiscus is the best known tropical flowering shrub in the world. It comes in various colors―single as well as double-petaled, native and hybrid strains, such that one is spoiled for choice. The genus includes annual and perennial herbaceous plants, as well as woody shrubs and small trees. They are very popular among gardeners and herbalist tea makers. Their growth requires minimal care and maintenance. Some training to prune them and pest control among other things is all they need. Among all the pests that infect this plant, aphids should be dealt with immediately. Aphids or plant lice are nasty, small, soft-bodied, plant-eating insects. They are extremely destructive in nature and are found on cultivated plants in temperate climates. There are about 4,400 species of aphids, and they may be green, yellow, white, brown, red or black, depending on the species and the plants they feed on.

Plants affected by any kind of aphids needs to be removed. You will find them close to the top of the stems and on and around the hibiscus flower buds. They secrete a sticky fluid known as honeydew on parts of the plant they infect, promoting the growth of black sooty mold fungus. Aphids feed on hibiscus using their needle-like mouth parts, by rupturing vessels that carry water, carbohydrates, and proteins, which plants use. This black color should help one easily identify the presence of aphids. Unchecked, these pests can spread quickly, infecting more parts of the plant. The black soot does not let sunlight penetrate through the infected part. Without adequate sunlight, hibiscus plants cannot use its pigment―chlorophyll for the process of photosynthesis, thereby, depriving it of food and other vital nutrients required for growth. This eventually weakens the plant and kills it, or damages the quality of flowers produced.

There are different ways in which one can use for killing aphids. They seem to infect the plant more in winters, so ensure proper sunlight and air circulation for the plants. They curl and yellow the leaves, flower and stems colonize, so the first thing that needs to be done is to prune away all affected plant parts, leaves along with the offending insects. If the infestation is severe, try spraying. While purchasing hibiscus from nurseries, check thoroughly for any infected part.

● Insecticides meant specifically for aphids should be sprayed straight onto the infected part. Hose it down completely.
● A strong flush of water will dislodge some and kill some.
● You can also make a soapy water solution at home by putting 2 tablespoons of any hand wash or detergent in 1 gallon of water, and spray it on them. The chemicals present in most detergents will destroy them. As this solution is not harsh to the plants, continue spraying until all aphids have been eliminated. Rinse off with plain water after an hour or two.
● Hibiscus does not tolerate too many insecticides and fertilizers. So don’t spray insecticides in excess; it will damage the plant, whereas over-fertilizing the plant will make it more susceptible to aphids.
● A chemical known as imidacloprid is also used for getting rid of aphids. It is used as a soil treatment, from where it enters the hibiscus through the roots, and is then circulated within the phloem vessels of the plants. This chemical interferes with the insect’s nervous system by causing a blockage to the stimuli transmission. As a result, aphids die. Before using this chemical, one should study its effects as well, as they are toxic and have the potential for ground and surface water contamination.

Aphids can damage your plant and make your beautiful hibiscus look really sad. So, get rid of them before they travel to other plants in the vicinity.
