How to Get Rid of Scales on Purple Velvet Plant

Introduction

Purple velvet plants, also known as Gynura aurantiaca, are beautiful houseplants that feature vibrant purple leaves with a velvety texture. However, like many other houseplants, they are susceptible to pests. One common pest that can infest purple velvet plants is scales. Scales are small, oval-shaped insects that attach themselves to the plant’s leaves and stems, feeding on its sap. If left untreated, scales can weaken the plant and hinder its growth. In this article, we will discuss effective methods to get rid of scales on purple velvet plants and restore their health.

Identifying Scales

Before we delve into the treatment options, it is essential to identify scales correctly. Scales are tiny insects that often resemble small bumps or shells on the plant’s surface. They come in various colors, including brown, black, or even transparent. When they feed on the plant’s sap, they excrete a sticky substance known as honeydew. This honeydew can attract ants and promote the growth of sooty mold, another plant disease.

Prevention is the Best Cure

As with any pest infestation, prevention is always better than cure. To minimize the risk of scales attacking your purple velvet plant, it is crucial to maintain good plant care practices:

Inspect new plants: Before introducing a new purple velvet plant to your collection, thoroughly inspect it for any signs of pests or diseases. Look for scales on both sides of the leaves and along the stems.
Quarantine new plants: It is advisable to keep new plants separate from your existing collection for a few weeks. This allows you to monitor them closely for any signs of infestation before introducing them to other plants.
Maintain proper hygiene: Regularly clean the leaves of your purple velvet plant using a damp cloth or sponge. This helps remove any dust or debris that may attract pests.
Avoid overwatering: Scales are attracted to moist conditions, so it is essential to water your purple velvet plant sparingly and only when the top inch of soil feels dry.

Natural Remedies for Scale Infestation

If your purple velvet plant is already infested with scales, there are several natural remedies you can try to get rid of them:

Manual removal: For small-scale infestations, you can physically remove the scales using a cotton swab dipped in rubbing alcohol. Gently rub the affected areas to dislodge the scales and wipe them away. Repeat this process regularly until all scales are removed.
Neem oil: Neem oil is a natural insecticide derived from the neem tree. It is effective against various pests, including scales. Mix one teaspoon of neem oil with one quart of water and apply it to the foliage of your purple velvet plant using a spray bottle. Make sure to cover both sides of the leaves and stems thoroughly. Repeat this treatment once a week until the scales are eradicated.
Insecticidal soap: Insecticidal soaps can be used to suffocate and kill scales. Mix one tablespoon of mild liquid soap (without additives like bleach or fragrance) with one quart of water and spray it onto the affected areas of your plant. Leave it on for a few hours, then rinse off with clean water. Repeat this treatment every 7-10 days until the scales are eliminated.
Beneficial insects: Introducing beneficial insects, such as ladybugs or predatory mites, can help control scale populations naturally. These insects feed on scales and their eggs, effectively reducing their numbers. You can purchase these beneficial insects online or from gardening supply stores.

Chemical Control Options

If natural remedies fail to eliminate the scale infestation on your purple velvet plant, you may consider chemical control options. However, it is crucial to use these chemicals with caution, following the instructions provided by the manufacturer:

Systemic insecticides: Systemic insecticides are absorbed by the plant and transported throughout its tissues. This makes them effective against scales that are difficult to reach with sprays. However, systemic insecticides should be used judiciously and sparingly, as they can harm beneficial insects and pollinators.
Contact insecticides: Contact insecticides are sprayed directly onto the scales, killing them upon contact. These products usually contain active ingredients like pyrethroids or horticultural oils. Before using any contact insecticide, carefully read and follow the instructions on the label.

Conclusion

Scales can be a frustrating pest to deal with, but with proper care and timely intervention, you can effectively get rid of them from your purple velvet plant. Remember to practice good plant hygiene, regularly inspect your plants for signs of infestation, and take immediate action at the first sight of scales. By following the preventative measures mentioned in this article and using natural or chemical control options as necessary, you can keep your purple velvet plant healthy and pest-free.
