Pests and Diseases
When it comes to pests and diseases, pampas grass is generally resilient, but it’s not infallible. A few unwanted guests might still make an appearance.
- Aphids: These tiny insects can sap the vitality from your pampas grass. If you notice clusters of these critters or see leaves curling, a strong blast of water can dislodge them. For severe infestations, consider insecticidal soap.
- Mealybugs: Recognizable by their cottony masses, mealybugs can be more persistent. Wiping leaves with alcohol-dipped cotton swabs usually does the trick.
- Fungal infections: Overly damp conditions can foster fungi, leading to rust or leaf spot. Ensure proper spacing for airflow and avoid overhead watering to keep fungal growth at bay.

Pink Pampas grass
The pink variety develops beautiful rose-pink plumes and generally performs best where summers are not excessively hot. However, pampas grass (Cortaderia selloana) is considered invasive in several parts of the United States because mature plants can produce thousands of windblown seeds that escape into roadsides, riverbanks, and other disturbed areas. It is restricted or prohibited in certain locations, so homeowners should check local regulations before planting it.
Pampas grass is usually less aggressive in Las Cruces and much of the arid Southwest because our limited rainfall makes it difficult for seedlings to survive without supplemental water. Even so, seeds may establish around irrigated landscapes, drainage areas, acequias, or other places that remain moist. Removing the flower plumes before seeds mature can help prevent unwanted spreading. California identifies pampas grass as an invasive plant, while Hawaii lists C. selloana and C. jubata as noxious weeds and restricts their importation.
