Drought-tolerant ground covers are an excellent solution for weed control and maintaining a low-maintenance garden. These plants are not only resilient in dry conditions but also provide a lush, green carpet that suppresses weeds effectively. By choosing the right ground cover, you can enhance your garden’s appearance while conserving water and reducing the need for chemical weed killers.
What Are the Best Drought-Tolerant Ground Covers for Weed Control?
Choosing the right drought-tolerant ground cover depends on your specific climate, soil type, and aesthetic preferences. Here are some popular options:
1. Creeping Thyme (Thymus serpyllum)
- Water Needs: Low
- Sun Exposure: Full sun
- Benefits: This aromatic herb forms a dense mat that crowds out weeds. It blooms with tiny purple flowers, attracting pollinators.
- Example: Ideal for rock gardens or between stepping stones.
2. Sedum (Stonecrop)
- Water Needs: Very low
- Sun Exposure: Full sun to partial shade
- Benefits: With its succulent leaves, sedum thrives in dry conditions and comes in various colors and textures.
- Example: Perfect for borders and slopes where water drainage is rapid.
3. Ice Plant (Delosperma cooperi)
- Water Needs: Low
- Sun Exposure: Full sun
- Benefits: Known for its vibrant flowers and succulent foliage, the ice plant is excellent for hot, sunny areas.
- Example: Use in coastal gardens or areas with sandy soil.
4. Lamb’s Ear (Stachys byzantina)
- Water Needs: Low
- Sun Exposure: Full sun
- Benefits: Its soft, silvery leaves create a striking contrast and deter weeds.
- Example: Useful in borders and mixed plantings for texture and color.
5. Creeping Jenny (Lysimachia nummularia)
- Water Needs: Moderate
- Sun Exposure: Full sun to partial shade
- Benefits: Although it prefers more moisture, creeping Jenny can survive drought once established. Its bright green leaves spread quickly.
- Example: Works well in containers or as a ground cover in shaded areas.
How to Plant and Maintain Drought-Tolerant Ground Covers
Preparing the Soil
Before planting, ensure your soil is well-draining. Amend heavy clay or compacted soils with compost or sand to improve drainage. This step is crucial for preventing root rot in drought-tolerant plants.
Planting Tips
- Spacing: Plant ground covers close together to quickly establish a weed-suppressing mat.
- Mulching: Apply a layer of mulch around new plantings to retain moisture and further inhibit weed growth.
Maintenance Practices
- Watering: Water deeply but infrequently to encourage deep root growth.
- Pruning: Trim back any overgrown areas to maintain shape and encourage dense growth.
- Fertilizing: Use a slow-release fertilizer sparingly, as excessive nutrients can promote weed growth.
