Ground covers are a practical solution for landscaping in acidic soil and cold climates. These plants not only enhance the aesthetic appeal of your garden but also protect the soil from erosion and suppress weeds. Choosing the right ground cover can be challenging due to the specific conditions of acidic soils and cold temperatures. Here, we explore the best options and provide guidance on how to select and maintain them effectively.

Practical Example: Wintergreen in a Cold Climate Garden
Consider a garden in a USDA Hardiness Zone 4 area. Wintergreen, with its evergreen leaves and bright red berries, offers a stunning visual contrast against the winter snow. This plant thrives under the shade of coniferous trees, which naturally acidify the soil, making it an ideal choice for acidic conditions. By planting wintergreen, you create a low-maintenance, year-round ground cover that enhances the garden’s aesthetic while supporting local wildlife.
