When it comes to cultivating your garden, one of the biggest challenges is looking for ways to deter aphids. Aphids are notorious for causing significant damage to plants over time. There are plenty of ways to keep your garden protected from these pests. Implement some of the tips listed below to help deter aphid from settling in your yard.

Know How to Recognize Them

To protect yourself from an aphid infestation, you have to be able to recognize them and signs of their damage. Aphids are small and pear-shaped. They are often green, but can also be brown, black, yellow or red. They often gather in clusters which makes them easier to spot on plants. Always check the undersides of plants if you are searching for aphids.
Many of these insects are flightless, but some sprout wings which allows them to more easily travel from one area to another. You can recognize damage from aphids by observing the plants in your garden and the areas around them. Aphids leave behind honeydew, which is a sticky substance that attracts other insects.
In addition to attracting ants, honeydew can cause property damage, including expensive damage to your vehicle’s paint. Plants impacted by aphids are often yellowing and look deformed. The leaves specifically can appear misshapen and curled.

Deal With Them Early

Use your knowledge regarding aphids to keep an eye out for them in your yard. The moment you notice the possible presence of aphids, address the issue quickly to help prevent an infestation that could severely damage and even kill the plants in your garden. If only one plant appears to have been infested with aphids, you can remove it from your yard entirely
If the plant cannot be removed, you can hose it down with water to remove the aphids. In addition to hosing infested plants down, you can regularly spray various solutions that help deter aphids. Certain solutions, such as garlic and onion spray solutions, need to be sprayed directly on top of clusters of aphids to help shoo them away.

Grow Plants That Discourage Aphids

Certain types of plants can act as an active deterrent for aphids. Plants such as onions, mint and garlic are disliked by aphids. Make sure to plant these in various parts of your garden. Research plants that aphids are attracted to. To help keep these plants safe from infestation, make sure you place plants that aphids actively dislike nearby.

Promote Their Natural Predators

Another way to help discourage the presence of aphids is to cultivate an environment that is friendly to their natural predators. Ladybugs are the natural predator of aphids. Many nurseries offer bags of ladybugs that you can then release in your garden to help lower the presence of aphids.
To help encourage ladybugs to remain in your garden, you will want to make sure you release them next to sources of food and water. Make sure you have a body of water nearby or that your plants are freshly watered before releasing them. Ensure that you open the bag of ladybugs near an infested plant so they will be readily aware of a good source of food. 
You may also want to release the ladybugs in a variety of areas within your garden to ensure that they each have an adequate supply of food and water and are able to address the different areas of infestation in your yard.

Sprinkle Flour Over Plants

Another natural way to help address aphids if they are invading your yard is to sprinkle flour over plants. Take up flour in the palms of your hands and sprinkle it evenly over plants that are infested by aphids. The aphids will consume the flour while attacking your plants, which will result in them becoming constipated and eventually dying.
By using the tips above, you can keep your garden protected and your plants looking healthy.
