How to Get Rid of Scales on Dew Plant

Dew plants are beautiful and interesting plants that can be grown both indoors and outdoors. They are commonly known for their ability to trap insects on their leaves, making them a popular choice for insectivorous plant enthusiasts. However, like any other plant, dew plants can also face challenges such as pests and diseases. One of the most common issues affecting dew plants is the presence of scales on the leaves. In this article, we will discuss what scales are, why they are harmful to dew plants, and how to get rid of them.

What are Scales?

Scales are small, oval-shaped insects that attach themselves to the leaves and stems of plants, sucking sap from them. They are often mistaken for part of the plant due to their hard, shell-like appearance. Scales come in different colors, shapes, and sizes depending on the species. The most common types of scales that affect dew plants are the armored scales and soft scales.

Why are Scales Harmful to Dew Plants?

Scales can cause a lot of damage to dew plants if left untreated. They weaken the plant by sucking out its sap, which can lead to wilting, yellowing leaves, stunted growth, and even death. Scales also create a sticky substance called honeydew that attracts ants and promotes the growth of sooty mold. Sooty mold is a black fungus that grows on the honeydew residue left by scales, making the leaves look dirty and unsightly.

How to Get Rid of Scales on Dew Plants

Getting rid of scales on dew plants requires a multi-step approach that involves both physical and chemical control methods. Here are some steps you can take to get rid of scales:

Step 1: Inspect Your Plant Regularly

Inspect your dew plant regularly for signs of scale infestation. Look for small, round bumps on the leaves and stems, as well as sticky residue and black sooty mold. Early detection is crucial in controlling scale infestation.

Step 2: Remove Scales by Hand

Use a soft-bristled brush or cotton swab dipped in alcohol to remove scales from the leaves and stems of your dew plant. This method is most effective when dealing with a small number of scales.

Step 3: Use Insecticidal Soap

Insecticidal soap is an effective and safe way to control scales on dew plants. It works by suffocating the scales and disrupting their cell membranes. Spray your dew plant with insecticidal soap according to the manufacturer’s instructions, making sure to cover all parts of the plant, including the undersides of the leaves.

Step 4: Apply Horticultural Oil

Horticultural oil is a type of oil that can be used to control scales on dew plants. It works by smothering the scales and preventing them from breathing. Apply horticultural oil to your dew plant according to the manufacturer’s instructions, making sure to cover all parts of the plant.

Step 5: Use Systemic Insecticides

Systemic insecticides are absorbed by plants and kill scales when they feed on them. This method is most effective when dealing with severe infestations. However, systemic insecticides should be used with caution as they can harm beneficial insects such as bees and butterflies. Follow the manufacturer’s instructions carefully when using systemic insecticides.

Regular inspection, physical removal, and the use of insecticidal soap, horticultural oil, and systemic insecticides can help control scale infestations. Remember to follow the manufacturer’s instructions carefully when using any chemical controls. With these methods, you can keep your dew plant healthy and thriving for years to come.
