Groundcovers are the unsung heroes of landscaping, bringing a multitude of benefits to your outdoor space while requiring minimal care. These plants offer versatile solutions for a variety of landscape challenges. In this guide, we’ll explore the many advantages of groundcovers and provide tips on how to choose, plant, and integrate them seamlessly into your landscape design.
The Many Benefits of Groundcovers:
Erosion Control:
Groundcovers act as nature’s net, preventing soil erosion on slopes and embankments. Varieties like Vinca minor (Periwinkle) and Phlox subulata (Creeping Phlox) are excellent choices for this purpose.
Weed Suppression:
Their dense growth habit shades the soil, making it difficult for weeds to take root. Consider low-maintenance options like Sedum spurium (Stonecrop) or Ajuga reptans (Bugleweed).
Soil Improvement:
Many groundcovers, such as Ajuga and Lamium maculatum (Dead Nettle), improve soil health by acting as living mulch, enhancing moisture retention, and promoting beneficial microorganisms.
Temperature Regulation:
Groundcovers help regulate soil temperatures, protecting plant roots from extreme heat in summer and insulating them from harsh cold in winter.
Choosing the Right Groundcovers:
When selecting groundcovers for zones 6 and 7, it’s essential to consider their cold tolerance. Some excellent options include:
Liriope muscari (Lilyturf):
A hardy evergreen with vibrant foliage that offers excellent erosion control.
Galium odoratum (Sweet Woodruff):
A fragrant, shade-loving ground cover ideal for wooded areas.
Pachysandra terminalis (Japanese Spurge):
A versatile, low-maintenance choice that thrives in both sun and shade.
Thymus praecox (Creeping Thyme):
Delicate, fragrant, and drought-tolerant, making it perfect for sunny areas.
Planting and Spacing:
To ensure success, plan your groundcover layout carefully:
Spacing:
Follow spacing recommendations on plant labels, typically 6 to 12 inches apart, depending on the variety.
Preparation:
Prepare the soil by removing weeds, rocks, and debris. Incorporate organic matter to improve fertility and drainage.
Planting:
Dig holes slightly larger than the root balls, place your groundcovers, and backfill with soil. Water thoroughly after planting.
Care and Maintenance:
Groundcovers are prized for their low-maintenance nature, but they do benefit from some care:
Watering:
Provide consistent moisture during the establishment phase. Once established, most groundcovers are drought tolerant.
Mulching:
Apply a layer of mulch to help retain soil moisture and suppress weeds.
Pruning:
Trim or mow groundcovers as needed to maintain their desired height and shape.
Incorporating Groundcovers Into Your Landscape:
Edging:
Frame pathways, driveways, and garden beds with groundcovers like Sedum ternatum (Wild Stonecrop) for a polished look.
Under Trees:
Replace thirsty grass with shade-loving groundcovers like Hosta or Epimedium for an attractive, low-maintenance solution.
Filler:
Use groundcovers as living mulch around established shrubs and perennials to reduce weed competition.
Rock Gardens:
Combine low-growing varieties like Aubrieta deltoidea (Rock Cress) with rocks for a picturesque alpine garden.
Groundcovers are versatile, practical, and stunning additions to any landscape. By carefully selecting, planting, and caring for these plants, you can enjoy their many benefits while elevating the beauty of your outdoor space.
