Planting & Care

Planting and caring for the Luminary® 'Ultraviolet' Tall Garden Phlox (Phlox paniculata) requires attention to a few key details to ensure it thrives and rewards you with its vibrant blooms and fragrance. Here is a comprehensive guide to help you grow this stunning perennial successfully:

Planting Instructions:

  1. Timing: Plant in spring or early fall to allow the plant time to establish before extreme temperatures set in. Cooler temperatures help the roots to grow without the stress of heat.
  2. Location: Choose a location that receives part sun to full sun (4-6 hours of sunlight daily). Although it is adaptable, more sunlight encourages better blooms.
  3. Soil Preparation: Phlox prefers well-drained soil. If your soil is heavy clay or too sandy, amend it with compost or peat moss to improve drainage and nutrient content.
  4. Planting Depth and Spacing: Dig a hole as deep as the root ball and twice as wide. Place the plant in the hole so that the top of the root ball is level with the soil surface. Space plants 28 to 32 inches apart to ensure good air circulation, which is vital for disease prevention.

Care Instructions:

  1. Watering: Water regularly to keep the soil consistently moist, especially during the first growing season to establish a deep, extensive root system. Once established, the plant can tolerate occasional dry spells, but optimal growth occurs with regular moisture.
  2. Mulching: Apply a layer of mulch around the base of the plant to retain soil moisture, regulate soil temperature, and reduce weed competition.
  3. Fertilizing: Feed in early spring with a balanced, slow-release fertilizer to encourage vigorous growth and flowering. Repeat feeding may be beneficial during the growing season, following the product's recommendations.
  4. Pruning: After the first bloom, deadhead (remove spent flowers) to encourage a second bloom period. In late winter or early spring, before new growth begins, cut back the plant's foliage to ground level to tidy the plant and promote healthy, fresh growth.
  5. Disease Management: Ensure good air circulation around the plants to reduce the risk of fungal diseases like powdery mildew. Selectively prune overcrowded areas if necessary. The Luminary® 'Ultraviolet' is noted for its disease resistance, but proper care can prevent any issues.
  6. Winter Care: In zones 3-8, the plant is perennial and should survive the winter without special care. In colder parts of its range, apply a protective layer of mulch after the ground freezes to insulate the roots.

Following these planting and care instructions will help your Luminary® 'Ultraviolet' Tall Garden Phlox to flourish, bringing color, fragrance, and life to your garden for many seasons.
