What Are the Best Ground Covers for Acidic Soil in Cold Regions?
Choosing the right ground cover for acidic soil in cold regions can be challenging, but several hardy varieties are well-suited for these conditions. Some of the top choices include creeping juniper, bunchberry, and sweet woodruff. Each of these plants offers unique benefits and can thrive in the demanding environments of cold climates with acidic soil.
Creeping Juniper: A Hardy Evergreen

Creeping juniper spreads quickly, creating a dense mat that effectively covers the ground and prevents soil erosion. Its needle-like foliage provides year-round color, making it a popular choice for gardeners seeking a visually appealing and durable ground cover.
Bunchberry: A Native Beauty
Bunchberry is a native ground cover that thrives in acidic soils and cold climates. This plant is particularly valued for its attractive flowers and berries.
- Scientific name: Cornus canadensis
- Hardiness zones: 2-7
- Sunlight: Partial shade to full shade
- Benefits: Attractive flowers, wildlife-friendly, shade-tolerant
Bunchberry produces white flowers in spring, followed by bright red berries in the fall. It is an excellent choice for shaded areas under trees, where it can create a lush, green carpet that attracts wildlife and adds natural beauty to your garden.
Sweet Woodruff: A Fragrant Ground Cover
Sweet woodruff is a fragrant ground cover that thrives in moist, acidic soils. It is known for its delicate white flowers and pleasant scent.
- Scientific name: Galium odoratum
- Hardiness zones: 4-8
- Sunlight: Partial shade to full shade

Sweet woodruff spreads quickly, making it an ideal choice for filling large areas. Its sweet-smelling foliage is often used in potpourris, and it is deer-resistant, reducing the risk of damage from wildlife.
How to Plant and Care for Ground Covers in Cold, Acidic Soils
Successfully planting and maintaining ground covers in cold, acidic soils requires careful planning and attention to soil conditions. Here are some tips to help you get started:
-
Test your soil: Determine the acidity level of your soil with a pH test kit. Ground covers like creeping juniper, bunchberry, and sweet woodruff prefer a pH range of 4.5 to 6.0.
-
Prepare the soil: Amend the soil with organic matter, such as compost or peat moss, to improve drainage and nutrient availability.
-
Planting: Plant ground covers in early spring or fall when temperatures are cooler. Space plants according to their growth habits to ensure adequate coverage.
-
Watering: Water newly planted ground covers regularly until they are established. Once established, most of these plants are drought-tolerant and require minimal watering.
-
Mulching: Apply a layer of organic mulch around the plants to retain moisture, suppress weeds, and maintain soil temperature.
