Drought-tolerant ground covers are an excellent choice for cold climates, providing year-round beauty and reducing water usage. These hardy plants can withstand dry conditions and harsh winters, making them ideal for sustainable landscaping. In this guide, we’ll explore some of the best options, practical tips for planting, and how to maintain these resilient ground covers.
What Are the Best Drought-Tolerant Ground Covers for Cold Climates?
Selecting the right drought-tolerant ground covers for cold climates involves choosing plants that can endure both limited water and freezing temperatures. Here are some top choices:
- Creeping Thyme (Thymus serpyllum): This aromatic herb is not only drought-tolerant but also cold-hardy, thriving in USDA zones 4-9. Its low-growing habit and purple flowers create a lush carpet.
- Sedum (Sedum spp.): Known for their succulent leaves, sedums are excellent for dry, cold climates. They come in various colors and textures, providing year-round interest.
- Bearberry (Arctostaphylos uva-ursi): Ideal for colder regions, bearberry offers evergreen foliage and bright red berries. It is hardy in zones 2-6 and thrives in sandy, well-drained soils.
- Snow-in-Summer (Cerastium tomentosum): With silvery foliage and white blooms, this plant is perfect for sunny, dry areas and can withstand temperatures as low as zone 3.
- Ajuga (Ajuga reptans): This versatile ground cover is known for its vibrant foliage and blue flowers. It is drought-resistant once established and suitable for zones 3-9.
How to Plant and Care for Drought-Tolerant Ground Covers
Preparing the Soil
Before planting, ensure your soil is well-drained and amended with organic matter. This helps retain moisture while providing necessary nutrients. Loosen the soil to a depth of about 6 inches and remove any weeds or debris.
Planting Tips
- Spacing: Space plants according to their mature size to allow for proper growth and air circulation.
- Watering: Initially, water plants regularly until they are established. Afterward, they will require minimal irrigation.
- Mulching: Apply a layer of mulch to conserve moisture and suppress weeds. Organic mulches like shredded bark or compost are ideal.
Maintenance Practices
- Pruning: Trim back dead foliage in spring to encourage new growth.
- Fertilizing: Use a balanced, slow-release fertilizer in early spring to promote healthy development.
- Pest Control: Monitor for pests like aphids or slugs and manage them with natural remedies or horticultural oils.
