Most Common Snow Bush Plant Pests:
Identification and Treatment Guide

Updated: July 27, 2023

Snow bush (Breynia disticha), also known as snow-on-the-mountain or sweetpea bush, is a popular tropical plant known for its attractive variegated leaves. While snow bush is generally easy to care for, it is not immune to pests. In this article, we will explore the most common pests that can infest snow bush plants, how to identify them, and the best treatment options available.

Aphids

Aphids are one of the most common pests that can infest snow bush plants. These small, soft-bodied insects feed on the sap of the plant, causing stunted growth and distorted leaves. If you notice curled or yellowing leaves on your snow bush, aphids may be the culprit.

To identify aphids, look for clusters of tiny insects on the undersides of leaves. They can be green, black, brown, or pink in color. You may also notice a sticky residue called honeydew on the leaves and nearby surfaces.

To treat aphids on your snow bush, start by spraying the plant with a strong stream of water to dislodge them. You can also use insecticidal soap or neem oil spray to control the infestation. Repeat the treatment every few days until the aphids are eliminated.

Spider Mites

Spider mites are another common pest that can attack snow bush plants. These tiny arachnids are not actually insects but are closely related to spiders. They suck the sap from the leaves, causing yellowing, stippling, and eventually leaf drop.

To identify spider mites, inspect the undersides of leaves for fine webbing and tiny specks that move when disturbed. You may also notice a dusty appearance on the leaves due to their feeding habits.

To control spider mites on your snow bush, first isolate the infected plant to prevent the infestation from spreading. Increase humidity around the plant by misting it regularly, as spider mites thrive in dry conditions. You can also use insecticidal soap or a solution of neem oil to treat the infestation. Repeat the treatment every few days until the spider mites are eradicated.

Scale Insects

Scale insects are another common pest that can affect snow bush plants. These small, oval-shaped insects attach themselves to the stems and leaves of the plant, sucking sap and causing yellowing, stunted growth, and leaf drop. They can be challenging to control as they have a protective shell that makes them resistant to many insecticides.

To identify scale insects on your snow bush, look for small bumps or shells on the stems and leaves. These bumps can vary in color depending on the species, ranging from brown to white.

To treat scale insects on your snow bush, start by manually removing them using a soft brush or cotton swab dipped in rubbing alcohol. Be sure to target both the adult insects and their nymphs. You can also use horticultural oil or insecticidal soap to suffocate and kill the insects. Repeat the treatment every 10-14 days until the scale insects are eliminated.

Mealybugs

Mealybugs are yet another common pest that can infest snow bush plants. These soft-bodied insects look like tiny cotton balls and feed on plant sap, causing yellowing leaves and stunted growth. They also produce honeydew, which can attract ants and lead to sooty mold growth.

To identify mealybugs on your snow bush, look for white, cottony masses on the stems and leaves of the plant. You may also notice a sticky residue on nearby surfaces.

To control mealybugs on your snow bush, start by manually removing them using a soft brush or cotton swab dipped in rubbing alcohol. You can also use insecticidal soap or neem oil spray to treat the infestation. Repeat the treatment every few days until the mealybugs are eradicated.

Conclusion

While snow bush plants are generally hardy and resistant to many pests, they can still fall victim to common insect infestations. By learning to identify the most common pests that affect snow bush plants and utilizing effective treatment options, you can keep your snow bush healthy and thriving. Remember to regularly inspect your plant for signs of infestation and take prompt action to prevent further damage. With proper care and attention, your snow bush can continue to be a beautiful addition to your garden.
