Plant Irish moss in spring or early summer. Situate plants about 10 inches apart; in ideal conditions, they will grow together to form a carpet of color in a couple of seasons. Plant Irish moss closer together for faster cover. Prolonged periods of hot, humid weather are not good for Irish moss. It thrives in cool, somewhat dry environments. Don’t be surprised if it dies out in the heat of summer in humid areas. Solve your perennial problems here.
A Weed to Some
Irish moss is sometimes called pearlwort and is considered a weed by many golf course professionals, nursery growers, and greenhouse managers. Pearlwort pops up in turf grass and throughout nurseries and greenhouses, and it’s sometimes tough to eradicate. In the average home lawn and landscape, it does not create a weed problem.
