What Is Sagina Moss?

Moss Look-Alikes

• In spite of its mosslike appearance, Sagina is not a true moss. Unlike moss that reproduces by spores and does not produce flowers or seeds, Sagina is a herbaceous plant with roots, stems, flowers and seeds. Sagina requires typical care required for most perennial plants, including good soil and occasional fertilization. Unlike Sagina, true moss tolerates full shade and often grows without soil. Moss often causes problems when it grows on roofs, bricks or concrete sidewalks.

Uses

• With a mature height of only 2 to 4 inches, Sagina spreads to form compact, rounded masses, creating a velvety green ground cover. Sagina grows well in semi-shady rock gardens and is often used to fill walkway cracks or gaps between paving stones. You can also plant Sagina in containers where the intense green provides contrast to brightly colored annuals or perennials. Sagina tolerates limited foot traffic but doesn't stand up to heavy use.

Growing Conditions

• Moderation is the key when it comes to sunlight. Sagina thrives in full sunlight and the plant may die in too much shade. However, in hot climates, direct sunlight can scorch the plants, especially if the soil isn't consistently moist. To protect the plant from intense sunlight, plant Sagina where it receives morning sunlight and afternoon shade. Sagina isn't fussy about soil and grows in average to poor garden soil as long as it is well-drained.

Planting and Care

• Although you can plant Sagina by seed, the easiest way to propagate the plant is by breaking off small chunks of a mature plant. Place the chunks on the prepared soil, then press them firmly so the roots make contact with the soil. You can also purchase small bedding plants at most garden centers. Before planting, spade the soil to a depth of at least 6 inches. Dig in 1 inch of compost along with a slow-release, 10-10-10 fertilizer applied at a rate of 4 tablespoons per 10 square feet of growing space.

Water and Fertilizer

• Water the plant at least once every week and more often during hot, dry weather. Let the surface of the soil dry slightly between waterings because Sagina rots in soggy soil. However, never let the soil become bone dry. Feed Sagina in spring and after blooming ends in early or midsummer, using a fish emulsion mixed at a rate of about 5 to 6 teaspoons in 1 gallon of water.
