Creeping Bentgrass, while not traditionally invasive, can spread aggressively and outcompete Moss Rose for resources, especially in moist conditions.

Aphids

These small insects suck sap from the plant, causing distorted growth and attracting ants. Look for clusters of aphids on stems and buds.

Mealybugs

Mealybugs appear as white, cottony masses on the plant. They weaken the plant by feeding on its sap, and can cause leaf yellowing and drop.

Steps:

    • Take stem cuttings from a healthy plant.
    • Allow the cuttings to dry for a day or two to form a callus.
    • Plant the cuttings in well-draining soil and water sparingly.
    • For seeds, sow directly into the soil after the last frost.

Effective natural insecticide against aphids and other pests.
