Phlox is a versatile and attractive perennial plant that can be used effectively as ground cover in gardens and landscapes. Its vibrant blooms and lush foliage create a colorful carpet that attracts pollinators such as butterflies and bees. Growing phlox as ground cover requires understanding its specific needs and care requirements to ensure healthy growth and abundant flowering.
Choosing the Right Phlox Varieties
There are many varieties of phlox suitable for ground cover, including creeping and spreading types. Some popular options include:
- Phlox subulata (Moss Phlox)
- Phlox stolonifera (Creeping Phlox)
- Phlox paniculata (Tall Garden Phlox, used in borders but can be low-growing in some cultivars)
For ground cover purposes, Phlox subulata and Phlox stolonifera are most suitable due to their low-growing, spreading habits.
Planting and Location
Choose a location that receives full sun to partial shade. Phlox thrives in well-drained soil with moderate fertility. When planting, space the plants about 12 to 18 inches apart to allow for spreading and growth. Prepare the soil by loosening it and adding organic matter if necessary to improve drainage and nutrients.
Care and Maintenance
Proper care ensures that your ground cover phlox remains healthy and vibrant. Key maintenance tips include:
- Watering: Keep the soil consistently moist, especially during the first growing season. Once established, phlox is relatively drought-tolerant.
- Fertilizing: Apply a balanced, slow-release fertilizer in early spring to promote healthy growth and flowering.
- Mulching: Use organic mulch around the plants to conserve moisture, suppress weeds, and maintain soil temperature.
- Pruning: Remove dead or damaged stems in early spring to encourage new growth and maintain a tidy appearance.
- Dividing: Every 3-4 years, divide the plants in early spring or fall to rejuvenate the ground cover and prevent overcrowding.
Controlling Pests and Diseases
Phlox can be susceptible to powdery mildew, especially in humid conditions. To prevent this:
- Ensure good air circulation by spacing plants adequately.
- Water at the base of the plants to avoid wetting foliage.
- Apply fungicides if necessary, following label instructions.
- Regularly inspect plants for pests such as aphids or caterpillars and treat accordingly.
Benefits of Using Phlox as Ground Cover
Using phlox as ground cover offers several advantages:
- Provides vibrant color and visual interest throughout the growing season.
- Suppresses weeds naturally by covering the soil.
- Requires minimal maintenance once established.
- Supports local pollinators, contributing to ecological health.
Conclusion
Growing phlox as ground cover is an excellent way to add color, texture, and ecological benefits to your garden. By selecting the right varieties, planting in suitable locations, and providing proper care, you can enjoy a lush, flowering carpet that enhances your landscape for years to come.
