To propagate holly, you can take cuttings from a healthy holly plant and place them in a container of well-draining soil. The best time to take cuttings depends on the type of holly, but it’s usually in the summer or late fall.
Steps
Select a healthy plant: Choose a holly plant with vibrant green leaves and no signs of disease or pests.

Prepare the cuttings: Dip the cut end in water, then rooting hormone
Plant the cuttings: Place the cuttings in a container with well-draining soil
Press down on the cuttings and water generously Place the container in a bright location with good ventilation
Care for the cuttings: Keep the soil moist
