Planting Phlox with Bulbs: Tips for a Stunning Mixed Garden Display

Creating a vibrant garden display can be a rewarding experience, especially when you combine the delicate beauty of phlox with the colorful bursts of bulbs. When planned thoughtfully, planting phlox alongside bulbs can produce a stunning mixed garden that blooms from early spring to late summer.

Choosing the Right Bulbs and Phlox

Start by selecting bulbs that bloom at different times to ensure continuous color. Popular choices include tulips, daffodils, and hyacinths for early spring, while alliums and lilies can extend the display into summer. For phlox, choose varieties suited to your climate and soil conditions, such as creeping phlox for ground cover or tall garden phlox for added height.

Preparing the Garden Bed

Prepare the soil by loosening it and adding organic matter like compost. Ensure good drainage to prevent bulb rot and root diseases. Mark the areas where you plan to plant bulbs, considering their mature height and spread to avoid overcrowding. Phlox prefers slightly acidic to neutral soil, so adjust pH if necessary.

Planting Bulbs

Plant bulbs at a depth of about three times their size, typically 4-6 inches deep. Space them according to their mature size, generally 3-6 inches apart. For a natural look, plant bulbs in clusters or drifts rather than in straight lines.

Planting Phlox

Plant phlox seedlings or divisions in gaps between bulbs or along the edges of the bed. Ensure they are spaced adequately to grow without overcrowding, usually 12-18 inches apart. Water thoroughly after planting to help establish roots.

Maintenance Tips for a Mixed Display

Water regularly, especially during dry spells, to support healthy growth. Mulch around the plants to conserve moisture and suppress weeds. Fertilize in early spring with a balanced fertilizer to promote vigorous blooms. Deadhead spent flowers to encourage additional flowering and maintain a tidy appearance.

Additional Tips for Success

  • Choose a sunny location; most bulbs and phlox thrive in full sun.
  • Plan for height differences; place taller phlox at the back of the border and shorter varieties at the front.
  • Consider the bloom time to ensure continuous color throughout the season.
  • Divide phlox every few years to prevent overcrowding and maintain vigor.
  • Remove faded flowers to encourage new blooms and keep the garden looking fresh.

By carefully selecting your bulbs and phlox, preparing the soil properly, and following maintenance best practices, you can enjoy a breathtaking mixed garden display that delights the eye from early spring through summer.
