How to Grow Phlox in New Mexico
Phlox is a vibrant and captivating flower that can add a splash of color to gardens across New Mexico. Known for its hardiness and diverse range of colors, phlox can thrive in various conditions, making it an excellent choice for both seasoned gardeners and beginners alike. This article will explore the best practices for growing phlox in New Mexico’s unique climate and how to care for these beautiful plants effectively.
Understanding Phlox
Phlox belongs to the Polemoniaceae family and comprises several species, including Phlox paniculata (garden phlox), Phlox subulata (moss phlox), and Phlox drummondii (annual phlox). These flowers come in various hues, including pink, purple, blue, white, and red. They can be categorized into two main types: perennial phlox, which returns year after year, and annual phlox, which blooms for one season.
Benefits of Growing Phlox
- Aesthetic Appeal: Phlox is known for its striking visual presence. Whether you choose low-growing moss phlox for ground cover or tall garden phlox as focal points, these flowers can enliven any garden space.
- Attracting Pollinators: The nectar-rich blooms of phlox attract butterflies and bees, positively contributing to the local ecosystem.
- Versatility: Different species of phlox can adapt to various environments—from borders and rock gardens to containers—making them suitable for diverse garden designs.
Best Time to Plant Phlox in New Mexico
The ideal time to plant phlox in New Mexico largely depends on the type of phlox you choose:
-
Perennial Phlox: For perennial varieties like garden phlox, spring is the best time to plant (typically between March and May). You can also plant them in fall (September to October) for early blooms in the following spring.
-
Annual Phlox: If you are growing annual varieties, the best time to sow seeds or transplant seedlings is after the last frost date, usually around mid-April.
Choosing the Right Location
Phlox thrives best in well-drained soil with plenty of sunlight. Here are key considerations when selecting a location:
Sunlight Requirements
In New Mexico’s high desert climate, most phlox varieties prefer full sun—at least 6 hours of direct sunlight per day. However, some species may tolerate partial shade, especially during the intense afternoon sun.
Soil Type
Phlox prefers rich, loamy soil with good drainage. Sandy or clay soils may require amendments like compost or peat moss to improve fertility and water retention. Conduct a soil test if you’re unsure about your garden’s capabilities.
Space Considerations
When planting multiple phlox plants, ensure they are spaced adequately—typically 12 to 18 inches apart for taller varieties and 6 to 12 inches apart for shorter ones—to allow air circulation and reduce disease risk.
Preparing the Soil
Preparation is essential for healthy growth. Follow these steps before planting:
- Clear the Area: Remove weeds and debris from your chosen planting bed.
- Amend the Soil: Incorporate organic matter such as compost or well-rotted manure into the soil to enhance nutrient levels.
- Level the Bed: Rake the area smooth to create an even surface for planting.
Planting Phlox
Planting Perennials
- Digging Holes: Make holes that are slightly larger than the root ball of your phlox plants.
- Positioning: Place each plant in its hole, ensuring that the top of the root ball is level with the soil surface.
- Backfilling: Fill in around the root ball with soil and gently tamp it down to eliminate air pockets.
- Watering: After planting, give your newly planted phlox a thorough watering.
Planting Annuals
- Preparation: Sow seeds directly into prepared soil or transplant seedlings after they have developed a few sets of true leaves.
- Spacing: Follow spacing guidelines according to seed packet instructions.
- Watering: Water gently but thoroughly after sowing or transplanting.
Watering Requirements
Phlox plants require consistent moisture but do not tolerate waterlogged conditions.
- Initial Watering: After planting, water your phlox deeply to establish roots.
- Regular Watering Schedule: Once established, water once a week unless rainfall provides adequate moisture.
- Drought Tolerance: While some phlox varieties are drought-tolerant once established, they will perform better with regular watering during dry spells.
Fertilization
To promote healthy growth and abundant flowering:
- Pre-Plant Fertilization: Mix a balanced fertilizer into your soil before planting.
- Post-Plant Fertilization: After blooming starts in late spring or early summer, apply a slow-release fertilizer according to package instructions.
Pruning and Deadheading
Maintaining your phlox encourages more blooms:
- Deadheading: Remove spent flowers throughout the blooming season to encourage further flowering.
- Pruning: At season’s end or in late fall, cut back perennial phlox stems to about 6 inches above ground level to prepare them for winter dormancy.
Pest Control & Disease Management
Phlox plants can be susceptible to pests such as aphids and spider mites as well as diseases like powdery mildew:
- Monitoring: Regularly check your plants for signs of pests or diseases.
- Organic Solutions: Use insecticidal soap or neem oil for pest control; removing affected leaves can help manage diseases like powdery mildew.
- Good Hygiene Practices: Keep your garden clean by removing debris and dead plant material that could harbor pests or pathogens.
Winter Care
New Mexico’s winter weather can vary widely depending on elevation:
- In areas with milder winters (lower elevations), mulch around perennial plants with straw or shredded leaves to protect roots from freezing temperatures.
- In higher elevations where temperatures drop significantly, consider covering plants with burlap or frost cloth during extreme cold snaps.
Conclusion
Growing phlox in New Mexico offers gardeners a wonderful opportunity to enhance their outdoor spaces with colorful blooms while supporting local pollinators. By understanding their needs regarding light, water, soil type, and care practices such as pruning and pest management, you can ensure that your phlox thrive season after season.
