Verbena plants are beautiful and easy to care for, but they can sometimes suffer from scale infestations. Scales are small, sap-sucking insects that can quickly multiply and cause damage to your verbena plant. If you notice scales on your verbena plant, it’s important to take action as soon as possible to prevent further damage. In this article, we’ll cover the steps you can take to get rid of scales on your verbena plant.
Before treating your verbena plant for scales, it’s important to make sure that the insects you see are actually scales. Scales are small, oval insects that attach themselves to the stems and leaves of plants. They have a hard, shell-like covering that protects them from predators and pesticides. If you’re not sure whether the insects on your verbena plant are scales, you can use a magnifying glass to get a closer look.
If the scales have spread throughout your verbena plant, it may be necessary to remove heavily infested parts. This will help prevent the scales from spreading to other parts of the plant or to other plants in your garden. Use pruning shears or scissors to cut off any heavily infested stems or leaves. Be sure to dispose of these parts in a sealed plastic bag or burn them so that the scales don’t survive and spread.
Once you’ve removed heavily infested parts, it’s time to wash the remaining parts of the plant. Use a gentle stream of water from a hose or spray bottle to wash away any remaining scales. Be sure to get both sides of the leaves and stems. This will help remove any eggs or nymphs that may be hiding on the plant.
Insecticidal soap is a safe and effective way to get rid of scales on your verbena plant. It works by suffocating the insects and disrupting their cell membranes. You can make your own insecticidal soap by mixing 2 tablespoons of dish soap with 1 gallon of water, or you can buy a ready-to-use insecticidal soap from your local garden center. Spray the soap solution onto the verbena plant, making sure to cover all parts of the plant. Be sure to follow the instructions on the label carefully.
Scales can be persistent, so it may take several treatments to get rid of them completely. Repeat the washing and insecticidal soap treatments every 7-10 days until you no longer see any scales on your verbena plant.
