How to Plant and Care for Native Ground Covers in Clay Soil
Preparing Your Clay Soil
Before planting, it’s essential to prepare the clay soil to ensure the best growth conditions for your native plants:
- Amend the Soil: Incorporate organic matter such as compost to improve drainage and soil structure.
- Test the pH: Ensure the soil pH is suitable for the selected plants, usually between 6.0 and 7.0 for most natives.
- Loosen the Soil: Break up compacted layers to allow roots to penetrate easily.
Planting Tips
- Spacing: Follow recommended spacing guidelines to allow plants to spread and form a dense cover.
- Watering: Water newly planted ground covers regularly until established, then reduce frequency.
- Mulching: Apply a layer of mulch to retain moisture and suppress weeds.
Maintenance Practices
- Pruning: Trim back ground covers to encourage denser growth and remove dead or damaged parts.
- Fertilizing: Use a balanced, slow-release fertilizer if necessary, but many natives thrive without additional feeding.
- Monitoring: Regularly check for pests and diseases, addressing issues promptly to maintain plant health.
