While not invasive everywhere, fountain grass can be aggressive in some climates and outcompete Elegia for resources.

Aphids

Aphids can infest Elegia tectorum, causing stunted growth and distorted leaves. They are small, soft-bodied insects that suck sap from the plant.

Mealybugs

Mealybugs are another common pest that can affect Elegia tectorum. They appear as white, cottony masses on the stems and leaves and can cause weakening and yellowing of the plant.

Steps:

    • Dig up a mature clump of Elegia tectorum in spring or autumn.
    • Carefully divide the clump into smaller sections, ensuring each section has roots and shoots.
    • Replant the divisions in well-draining soil and water thoroughly.
