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

  1. 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.
  2. Attracting Pollinators: The nectar-rich blooms of phlox attract butterflies and bees, positively contributing to the local ecosystem.
  3. 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:

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:

  1. Clear the Area: Remove weeds and debris from your chosen planting bed.
  2. Amend the Soil: Incorporate organic matter such as compost or well-rotted manure into the soil to enhance nutrient levels.
  3. Level the Bed: Rake the area smooth to create an even surface for planting.

Planting Phlox

Planting Perennials

  1. Digging Holes: Make holes that are slightly larger than the root ball of your phlox plants.
  2. Positioning: Place each plant in its hole, ensuring that the top of the root ball is level with the soil surface.
  3. Backfilling: Fill in around the root ball with soil and gently tamp it down to eliminate air pockets.
  4. Watering: After planting, give your newly planted phlox a thorough watering.

Planting Annuals

  1. Preparation: Sow seeds directly into prepared soil or transplant seedlings after they have developed a few sets of true leaves.
  2. Spacing: Follow spacing guidelines according to seed packet instructions.
  3. Watering: Water gently but thoroughly after sowing or transplanting.

Watering Requirements

Phlox plants require consistent moisture but do not tolerate waterlogged conditions.

Fertilization

To promote healthy growth and abundant flowering:

  1. Pre-Plant Fertilization: Mix a balanced fertilizer into your soil before planting.
  2. 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:

Pest Control & Disease Management

Phlox plants can be susceptible to pests such as aphids and spider mites as well as diseases like powdery mildew:

  1. Monitoring: Regularly check your plants for signs of pests or diseases.
  2. Organic Solutions: Use insecticidal soap or neem oil for pest control; removing affected leaves can help manage diseases like powdery mildew.
  3. 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:
