Most Common Trailing Ice Plant Pests:
Identification and Treatment Guide

Introduction

Trailing ice plants (Delosperma spp.) are a popular choice for ground cover in many gardens and landscapes due to their attractive succulent foliage and vibrant, daisy-like flowers. However, like any other plant, trailing ice plants are susceptible to various pests that can cause damage and compromise their overall health. In this article, we will explore some of the most common pests that affect trailing ice plants, how to identify them, and the best treatment options available.

Aphids

Aphids are small, soft-bodied insects that feed on the sap of plants. They can be found clustered on the undersides of leaves or along the stems of trailing ice plants. These pests can cause distortion of new growth, yellowing of leaves, and even transmit viral diseases.

Identification: Aphids are typically green or black in color but can also appear in shades of yellow or brown. They have pear-shaped bodies and long antennae. When present in large numbers, aphids can be easily seen with the naked eye.

Treatment: The first step in controlling aphids is to physically remove them by spraying the affected plants with a strong stream of water. This will dislodge the insects from the plant. Alternatively, you can use insecticidal soap or neem oil to eliminate aphids. Be sure to follow the instructions on the product label for safe and effective use.

Mealybugs

Mealybugs are another common pest that affects trailing ice plants. These soft-bodied insects are covered in a white, waxy substance that gives them a mealy appearance. They feed on plant sap and can cause leaf yellowing, stunted growth, and wilting.

Identification: Mealybugs are small, oval-shaped insects that range in color from pale yellow to light brown. They are covered in a white, powdery wax that protects them from predators and environmental conditions. Mealybugs are usually found on the undersides of leaves, along stems, or in leaf axils.

Treatment: To control mealybugs, it is important to isolate the affected plants to prevent the spread of infestation. You can physically remove mealybugs by gently wiping them off with a cotton swab dipped in rubbing alcohol or soapy water. Another effective treatment option is to use insecticidal soap or horticultural oil to suffocate the pests. Repeat the treatment as necessary until all mealybugs are eliminated.

Spider Mites

Spider mites are tiny pests that are difficult to see with the naked eye. They are a common problem for trailing ice plants, especially in hot and dry conditions. These pests feed on plant sap and cause stippling, discoloration, and webbing on the leaves.

Identification: Spider mites are usually red or brown in color but can also be green or yellow. They have eight legs and a round, oval-shaped body. Although they are difficult to see individually, their presence can be detected by the fine silk webbing they produce on the leaves.

Treatment: To control spider mites, it is important to maintain a humid environment around the affected plants as these pests thrive in hot and dry conditions. Regularly misting the plants or placing them on trays filled with water can help increase humidity levels. Additionally, you can use insecticidal soap or neem oil to control spider mites. Apply the treatment thoroughly, ensuring that all affected areas are covered.

Slugs and Snails

Slugs and snails are common garden pests that can damage trailing ice plants by feeding on their leaves and flowers. These pests are most active during damp and cool conditions, such as early mornings or after rainfall.

Identification: Slugs and snails leave behind a trail of slime as they move, making their presence easily detectable. These pests have soft bodies and are usually brown or gray in color. They can be found hiding under plant debris, rocks, or in damp areas of the garden.

Treatment: To control slugs and snails, you can create barriers around your plants using materials such as copper tape or diatomaceous earth. These substances create a rough surface that is unpleasant for slugs and snails to crawl over. Additionally, you can handpick these pests and dispose of them away from your garden. If the infestation is severe, you can consider using organic slug and snail baits.

Conclusion

Trailing ice plants can be a beautiful addition to any garden or landscape, but it is important to be aware of the common pests that may affect them. By identifying these pests early on and implementing appropriate treatment measures, you can ensure the health and vitality of your trailing ice plants. Remember to always follow the instructions on any pest control products used and monitor your plants regularly to catch any signs of infestation before they become a major problem. With proper care and attention, your trailing ice plants will thrive and continue to enhance your outdoor spaces for years to come.
