How to Grow Irish or Scotch Moss (Sagina Subulata)

Though not a true moss, Irish moss (sometimes called Scotch moss) forms a tight mound like moss does, and it works well as a ground cover around stepping-stones and in rockeries. Irish moss thrives in USDA zones 6 to 9.

Instructions

Difficulty: Easy

Things You’ll Need:

• Fertilizers
• Garden Hoses
• Garden Spades
• Mulch
• Plants
• Seeds
• Shovels

1. Look for plants at nurseries in spring and summer, or year-round in warmer climates.
2. Choose healthy-looking plants with signs of new growth in leaves and flower buds. Buy Irish moss in 4-inch to 1-gallon containers.
3. Choose a site with full sun or partial shade and well-drained soil.
4. Dig a hole for each plant no deeper than the plants were growing in their containers; space the holes 6 inches apart.
5. Add a light application of organic fertilizer to the planting holes before setting the plants in.
6. Mulch around but not on top of the plants with 3 inches of organic compost.
7. Water well until soil is completely moist, weekly during the first year and in summers with no rainfall.
