Crossandra plants are known for their beautiful orange flowers and glossy green leaves, making them a popular choice for indoor and outdoor gardens. However, these plants can fall prey to a common pest called lerps, which can damage the leaves and affect the overall health of the plant. In this article, we will discuss what lerps are, how they affect crossandra plants, and most importantly, how to get rid of them.
What are Lerps?
Lerps are small, white, waxy structures that appear on the leaves of plants. They are created by tiny insects called psyllids that feed on the sap of the plant. The psyllids excrete a sugary substance that forms a protective cover over themselves and their eggs. These covers are called lerps.
How do Lerps Affect Crossandra Plants?
Lerps can cause significant damage to crossandra plants. They feed on the sap of the plant, which can weaken it and cause stunted growth. The lerps themselves can also block sunlight from reaching the leaves, which can further harm the plant’s growth. If left untreated, a severe infestation of lerps can even kill a crossandra plant.
How to Get Rid of Lerps on Crossandra Plants
There are several methods that you can use to get rid of lerps on your crossandra plant. Here are some of the most effective ones:
1. Prune affected leaves
The first step in getting rid of lerps is to prune any affected leaves. This will not only remove the lerps but also prevent them from spreading to other parts of the plant.
2. Use a strong stream of water
Using a strong stream of water is another effective way to get rid of lerps. Simply spray the affected leaves with a strong jet of water, making sure to hit the undersides of the leaves where the lerps like to hide.
3. Apply insecticidal soap
Insecticidal soap is a natural and effective way to get rid of lerps. You can purchase it at most garden centers or make your own by mixing 1 tablespoon of mild liquid soap with 1 quart of water. Spray the affected leaves with the solution, making sure to cover both the tops and bottoms of the leaves.
4. Use neem oil
Neem oil is another natural and effective way to get rid of lerps. Mix 1 tablespoon of neem oil with 1 quart of water and spray the affected leaves with the solution. Neem oil works by disrupting the life cycle of the psyllids, preventing them from reproducing.
Are lerps harmful to humans?
No, lerps are not harmful to humans. They do not bite or sting and are not known to carry any diseases.
Can I prevent lerps from infesting my crossandra plant?
Yes, you can take several steps to prevent lerps from infesting your crossandra plant. These include regularly inspecting your plant for signs of infestation, keeping your plant well-watered and fertilized, and avoiding over-fertilizing, which can attract psyllids.
Can I use chemical pesticides to get rid of lerps?
Yes, you can use chemical pesticides to get rid of lerps, but we recommend using natural methods first. Chemical pesticides can harm beneficial insects and pollinators and may also be harmful to humans and pets if used incorrectly.
In conclusion, getting rid of lerps on your crossandra plant is essential to maintain its health and beauty. Pruning affected leaves, using a strong stream of water, applying insecticidal soap, and using neem oil are all effective ways to get rid of lerps naturally. By following these methods and taking preventive measures, you can keep your crossandra plant healthy and thriving for years to come.
