Answer: Irish moss grows best in full sun to light shade and in good, well-drained soil. With time, one plant forms an attractive carpet of greenery. Occasionally, growth becomes crowded, pushing sections of the carpet upward. If you consider this less attractive, cut out a slice of the plant and push down until the roots are in contact with the soil. Any empty space resulting from this surgery will be quickly filled with greenery.
Best wishes with your garden!
