How to Grow Moss for Your Garden

Some homeowners cringe at the presence of mosses (Bryophyta group) among grasses and gardens, but, for moss lovers, the sight calls for celebration. Inspired by soothing Japanese gardens and historic European moss lawns, moss gardeners surrender space and encourage mosses to move in. Mosses encompass many plant families and number in the thousands of species, some native to every region. By balancing natives with simple moss basics, you can grow your own moss -- outdoors or in.

What's So Special About Mosses?

Besides their rich colors and velvety textures, mosses stand out from other plants in basic ways. True mosses are primitive plant forms without roots and vascular systems. Unlike most plants, mosses soak in moisture and nutrients from above and draw them from below, like candlewicks, while held in place by threadlike structures known as rhizoids.

Despite common perceptions, mosses don't crowd out lawn grasses; instead, they move into challenging areas where grasses failed. Nurturing moss-preferred conditions gives these lush native plants an advantage over others.

Some specialty nurseries offer true mosses, but most garden centers rarely carry them. The perennial ground covers at these places are mosses in common name only. For true moss gardens, look beyond these perennials to mosses that naturally occur in your area.

Duplicating Ideal Conditons

Mosses excel in conditions that many other plants hate. Consistently wet, poorly drained, compacted, acidic soil is a moss-lover's dream. Some mosses tolerate sun with plentiful moisture, and some desert mosses tolerate extended drought, but most common mosses prefer wet, medium-to-dense shade, where few plants compete.

If moss already grows in your lawn or garden, cultivating more comes easily. Let moss spread on its own or remove grass and other plants to speed the process. If you're short on natural moss, simple steps encourage its growth.

Mosses prefer acidic soil with a pH near 5.5 or lower -- a range where lawn grasses and weeds struggle. If soil testing shows higher pH levels, follow test recommendations to lower soil pH. For example, broadcast 1 pound of elemental sulfur per 100 square feet to lower soil pH by 1.0 unit. Wear protective clothing, including gloves and safety eyewear, and work the sulfur into the soil.

Transplanting Native Moss

Many mosses transplant easily from their natural locations. Some mosses lift like woodland rugs and relocate like sod. As with all native plants, mosses may be protected in some areas. Know your local laws, and never gather moss from public or private lands without permission.

When scouting out moss for your garden, look for conditions that match your own. Identifying mosses can be difficult -- even for moss experts -- so don't worry about species. Mosses from wet, low-lying areas require wetter garden sites than mosses from tree stumps or drier, higher areas. Matching natural habitats translates to healthy moss and less maintenance.

Mosses have two basic forms: carpet types and mounding types. Pieces 6 to 8 inches across transplant easiest because they dry out more slowly, but any size can work. Insert a spade or long knife under the moss, and lift it gently. Place the pieces where you want them, and firmly press them into place. Move moss during your region's rainy season, when natural precipitation helps keep it moist.

Maintaining Moss Gardens

Newly transplanted mosses need regular watering through their first year of establishment. Water them any time the soil dries out, including winter months. Mosses are very sensitive to fertilizers, which also encourage competing grass and weeds. Keep soil pH in proper ranges, and avoid extra fertilizers.

Naturally occurring mosses need very little maintenance. Keep moss gardens free of fallen leaves and other debris that block light and smother mosses. Rake leaves gently or use a leaf blower. If tiny tree seedlings or other plants appear, cut them off at the soil line. Pulling out their roots can dislodge moss.

Mosses are tough and resilient, but they don't tolerate heavy foot traffic. Thick moss cushions take several years to establish and spread. Strategic flagstone paths or pavers protect moss from damage.

Expressing Your Artistic Side

Garden mosses aren't limited to horizontal surfaces. You can recreate the look of ancient retaining walls, paint designs in moss, or cover pots with living color. While small pieces transplant to tiny stone crevices, a blend of moss and water helps get gardens and other moss projects started fast.

Blend equal parts of small moss pieces and water in a common household blender to form a thick slurry of paintable moss. Add extra moss to thicken the mixture as needed, and then paint or spread it on surfaces you want covered. For clay pots and rocks, add 3 parts potter's clay to 1 part fish emulsion fertilizer for extra sticking power and support.

Mist moss projects regularly, so they stay fresh and green as moss takes hold. Don't use a hose to water; new moss dislodges easily from vertical surfaces.

Growing Moss Indoors

Mosses flourish indoors when they have proper conditions. The same basic care rules apply, and lower indoor light levels are welcome. Tuck mosses in around forced bulbs, let them blanket container soils, or create miniature moss gardens or terrariums for indoors.

Mosses are sensitive to pollution. Chemicals and softening salts in tap water trigger those sensitivities. Water indoor mosses with reverse-osmosis water, distilled water or rainwater whenever possible. At a minimum, let tap water sit overnight.

Indoors mosses grow on the same foundations that outdoor mosses handle, including stones, twigs, sand and soil. When mosses lack water, colors dull and pleasant textures diminish. Mist and water indoor mosses regularly to keep them vibrant and soft. Move them back outside whenever you desire.
