No gardener wants to see their beautiful roses being threatened by an infestation of aphids. Left untreated, they can distort growth and over time weaken the plants. They could also be attracting ants that like to feed off the honeydew the aphids produce. While aphids on rose bushes and other plants are incredibly common, it’s best to tackle the issue as soon as you notice it. You can follow these five tips to get rid of aphids quickly for lasting results.

What are aphids?

Aphids are small insects no bigger than a quarter of an inch. They may be white or green or black. The little critters settle on leaves and stems of rose bushes to feed off the sap. They usually form colonies quickly so where you notice a few, there’ll be hundreds soon. Because they feed by piercing the leaves and sucking out the sap, they can transfer diseases to a plant that may spread through an entire rose garden. Damage from aphids is easy to spot: you’ll notice leaves that are misshapen or that begin to curl. Sometimes they may hide underneath the leaves, so check both sides if you suspect an aphid infestation of your roses.

 

Unfortunately, cutting your roses won’t get rid of the aphids. So, let’s discover how to get rid of aphids on roses.

Wash them off manually – if detected early

If you’ve spotted a few aphids, wipe the leaves and stems of the plant with a wet cloth. This will stop an infestation before it has begun and spread to other parts of the plant. This will only be feasible during the very early stages of an infestation.

Use a hose to wash them off

Aim a stream of water at the plants that have become infested. This will knock off the aphids from the leaves. It’s best to do this every day until you no longer see any aphids and are sure that they won’t return. 

Add good insects

Insects like ladybugs love to munch on aphids. You can get ladybugs online to release into your garden. They’ll be helping you to get rid of the aphids naturally. Once they’ve eaten the aphids, the ladybugs will move on to other gardens. 

Use an insecticide

Insecticides shouldn’t be your first bet. That’s because synthetic sprays and oil will kill off beneficial insects like ladybugs as well. But if the infestation is very stubborn, they can be incredibly powerful at getting rid of aphids on roses. There are two different main types to treat aphids.

 

The insecticide soaps are made with potassium salts which kill the aphids when they come into contact with them. These sprays are usually applied once a week and more often when it rains. Simply follow the instructions on the packaging.

 

The other type is an oil-based spray that lists mineral oils as the main ingredient. They work by smothering the aphids and should be applied more frequently when it rains.

 

Instead of buying insecticides, you could make your solution using tomato leaves. You’ll need:

  • Tomato leaves
  • 2 cups of water
  • Spray bottle

Simply chop up the leaves and soak them in the 2 cups of water overnight. Then strain the leaves and add the mixture to the spray bottle. Apply to your rose bushes and repeat spraying every 2 to 3 days. With all that, you should have defeated aphids on your rose bushes forever!
