Plant Overview

Irish Moss is a delightful, low-growing ground cover that creates a lush, carpet-like appearance reminiscent of a soft green cushion. Despite its common name, its not actually a moss but rather a flowering perennial that forms dense mats of tiny green leaves. This versatile plant is perfect for filling spaces between stepping stones, rock gardens, or as an alternative to traditional grass in small areas.

Plant Care

Irish Moss thrives with minimal maintenance once established. Regular watering is essential during the first growing season to develop a deep root system. While drought tolerant once established, it performs best with consistent moisture. Remove any dead foliage in early spring and trim if needed to maintain desired shape. Fertilization is typically unnecessary, but a light application of balanced fertilizer in spring can promote healthy growth.

Planting Instructions

Plant Irish Moss in spring or early fall for best results. Prepare the planting area by loosening the soil to a depth of 6 inches and incorporating organic matter. Space plants 6-8 inches apart to allow for spread. Plant at the same depth as the nursery container, ensuring the crown is level with the soil surface. Water thoroughly after planting and maintain consistent moisture until established. For use between pavers or stones, ensure soil depth is at least 2 inches and prepare the area by removing all weeds and grass.
