Cordyline Glauca, also known as Ti Plant or Hawaiian Good Luck Plant, is a popular houseplant known for its colorful foliage and easy care. However, one common problem that Cordyline Glauca owners face is the presence of lerps on the plant. Lerps are small, white, waxy bumps that appear on the underside of leaves and can cause damage to the plant if left untreated. In this article, we will discuss how to get rid of lerps on Cordyline Glauca plant.

What are Lerps?

Lerps are small sap-sucking insects that cover themselves with a protective waxy coating. They are commonly found on the undersides of leaves and can cause damage to plants by sucking sap from the foliage. Lerps are often mistaken for scale insects because of their similar appearance. However, unlike scale insects, lerps can be easily removed from plants.

Signs of Lerp Infestation

The presence of lerps on a Cordyline Glauca plant can be identified by the white, waxy bumps found on the undersides of leaves. Other signs of lerp infestation include yellowing or browning of leaves, stunted growth, and wilting.

How to Get Rid of Lerps

There are several ways to get rid of lerps on Cordyline Glauca plant:

1. Manual Removal

The most effective way to get rid of lerps is by manually removing them from the plant. Use a soft-bristled brush or a cotton swab dipped in rubbing alcohol to gently scrub off the lerps from the underside of leaves. Be sure to discard any fallen lerps and clean your tools after use.

2. Soap Water Solution

Another effective method to get rid of lerps is by using a soap water solution. Mix a few drops of dish soap in a spray bottle filled with water and spray the solution on the affected leaves. The soap will dissolve the waxy coating of the lerps, making them easier to remove. Rinse the plant with clean water after treatment.
