Living Mulch: A Natural, Low-Maintenance Groundcover Solution

Mulching is an essential practice in gardening, helping to retain moisture, suppress weeds, and regulate soil temperature. While traditional mulches like wood chips or straw are effective, living mulch—low-growing plants that act as a natural groundcover—offers even more benefits. In addition to providing these same advantages, living mulch also enriches the soil, supports pollinators, and adds beauty to the landscape.

Choosing the Right Living Mulch for Your Garden

Different plants thrive under different conditions. When selecting a living mulch, consider factors like sun exposure, soil type, and moisture levels. Below are some excellent living mulch options categorized by growing conditions.

Full Sun Options

• Creeping Thyme (Thymus serpyllum) – Forms a dense, aromatic mat and is drought-tolerant.

• Blue Star Creeper (Isotoma fluviatilis) – A dense, low-growing groundcover with small blue flowers that thrives in full sun and tolerates light foot traffic.

• Oregano (Origanum vulgare) – A low-growing, aromatic herb that thrives in full sun and provides seasonal interest.

Partial Sun Options

• Sweet Woodruff (Galium odoratum) – A delicate, fragrant groundcover that thrives in light shade.

• Strawberry Begonia (Saxifraga stolonifera) – A low-growing, spreading groundcover with attractive foliage and delicate flowers that thrives in partial sun.

• Ajuga (Ajuga reptans) – Forms a thick carpet with colorful foliage and springtime blooms.

Shade Options

• Pachysandra (Pachysandra terminalis) – A tough, evergreen groundcover ideal for deep shade.

• Golden Star (Chrysogonum virginianum) – Offers bright yellow flowers and thrives in moist, shady areas.

• Foamflower (Tiarella cordifolia) – A native groundcover with attractive foliage and spring blooms.

Dry Soil Options

• Sedum (Sedum spp.) – Succulent groundcovers that tolerate drought and poor soils.

• Wintercreeper (Euonymus fortunei) – A hardy, evergreen groundcover that thrives in dry soil and provides year-round interestr.

• Ice Plant (Delosperma spp.) – Produces vibrant flowers and thrives in arid conditions.

Moist Soil Options

• Creeping Jenny (Lysimachia nummularia) – A fast-spreading, golden-green plant that loves damp areas.

• Marsh Marigold (Caltha palustris) – Thrives in wet environments and adds bright yellow blooms in spring.

• Blue-eyed Grass (Sisyrinchium angustifolium) – A moisture-tolerant, low-growing perennial with grass-like foliage and charming blue flowers that thrive in wet conditions while attracting pollinators.

Caring for Living Mulch

Living mulch requires less maintenance than traditional mulch but still benefits from some care to keep it lush and healthy:

• Regular Trimming – Some species, like creeping jenny or ajuga, spread aggressively. Trim them back to prevent them from overtaking other plants.

• Watering Needs – Although many living mulches are drought-tolerant, watering during establishment helps them take root and spread.

• Weed Management – Once established, living mulch helps suppress weeds, but occasional weeding may be needed in early growth stages.

• Soil Health – Adding compost or organic matter occasionally can keep the soil fertile and promote vigorous growth.

• Dividing and Replanting – Over time, some groundcovers may become too dense. Dividing them every few years helps maintain their health and spread.

Enhancing Your Landscape with Living Mulch

Living mulch not only replaces traditional mulch but also enhances biodiversity and soil health. Whether used in vegetable gardens, flower beds, or pathways, these plants create a dynamic and sustainable groundcover that offers year-round beauty and function. By selecting the right species for your growing conditions and providing minimal care, you can enjoy the benefits of a lush, low-maintenance landscape.
