Planting & Care

Planting and caring for the Luminary® 'Backlight' Tall Garden Phlox (Phlox paniculata) is straightforward, making it accessible to gardeners of all skill levels. Here’s how to ensure this stunning perennial thrives in your garden:

Planting Instructions:

  • Timing: The best time to plant is in the spring or early fall to allow the plant to establish itself during the cooler, moist periods.
  • Location: Choose a site that receives part sun to full sun (at least 4-6 hours of sunlight daily). Adequate sunlight is crucial for optimal flowering.
  • Soil: Phlox prefers consistently moist, well-drained soil. It can tolerate a range of soil types, from average to fertile, and prefers a slightly acidic to neutral pH.
  • Spacing: Plant them about 20 to 24 inches apart to ensure proper air circulation, which is vital for preventing disease.
  • Planting Depth: Dig a hole as deep as the root ball and twice as wide. Set the plant in the hole at the same level it was growing in its nursery pot. Fill the hole with soil and press firmly.

Care Instructions:

  • Watering: Water regularly to keep the soil consistently moist, especially during dry spells. Phlox does not like to dry out.
  • Mulching: Apply a layer of mulch around the base of the plant to help retain soil moisture and keep the root zone cool.
  • Fertilizing: Feed your Phlox in early spring with a slow-release, balanced fertilizer to support vigorous growth and abundant flowering.
  • Pruning: After blooming, you can deadhead spent flowers to encourage a second bloom and to keep the plant looking tidy. In late winter or early spring, cut back any dead stems to ground level to make way for new growth.
  • Disease Prevention: Good air circulation is crucial for preventing powdery mildew and other fungal diseases. Avoid overcrowding and water at the base of the plant to keep foliage dry.
  • Winter Care: In colder zones, apply a protective layer of mulch after the ground freezes to help insulate the root system.

Additional Tips:

  • Disease Resistance: Luminary® 'Backlight' is noted for its excellent disease resistance, especially to powdery mildew, which can be a common issue with Phlox. This makes it easier to care for compared to other varieties.
  • Attracting Wildlife: This plant is excellent for attracting pollinators. Consider planting it in groups to create an abundant source of nectar.
  • Companion Planting: Phlox pairs well with other perennials that enjoy similar growing conditions, such as Echinacea, Rudbeckia, and Salvia. These combinations can create a vibrant and healthy garden ecosystem.

By following these planting and care guidelines, your Luminary® 'Backlight' Tall Garden Phlox will become a luminous fixture in your garden, offering dazzling white blooms and a welcoming environment for pollinators throughout the growing season.
