What Does Creeping Phlox Look like When Not in Bloom? 

If you’re wondering what creeping phlox look like when not in bloom, then let me enlighten you. These easy-to-grow fragrant flowering plants are quite attractive whether they are in bloom or not. During the spring season, you will get to see the beauty of their flowers as it is the time of year when they are in full bloom.

Their shaded flowers come in an array of colors which include white, purple, blue, and pink. However, when these plants are not in bloom, they are still quite an eye-catching garden beauty. Without flowers, they show off their needle-like bright green foliage, which is known to enhance the look of any landscape.

So, a phlox not flowering shouldn’t really be a worry, especially when it comes to the extent to which they beautify your yard without their candy-colored blooms.

Creeping Phlox Light Requirements

When it comes to creeping phlox light requirements, there are a few things that you should keep in mind. These plants, although hardy, grow to their full potential when afforded full sunlight. Although creeping phlox plants can tolerate partially shaded light, to get exceptional blooms, full sun is recommended. Keep in mind that if these plants are grown in the right conditions, they will eventually become well-established and able to grow healthily in the case of drought.

However, to reach this stage, creeping phlox plant care and maintenance are vital. Seeing that the phlox plant does well in soil with efficient drainage properties, planting them on slopes will enhance the growing mediums’ capabilities. So, to ensure fully flowered phlox plants through the blooming season, it is best to plant them away from large trees that will block direct sunlight. Monitoring when does creeping phlox blooms should be an important plant of your plant care implementations. 

What to Do with Phlox After Flowering?

So, you have creeping phlox plants in your garden and are wondering what to do with phlox after flowering. After flowering, it is essential to deadhead your phlox plant. The reason that this is recommended is that it will enhance the plant’s appearance and neaten it up. Thereafter, in the coming autumn or winter seasons, it is best to cut your phlox plants down to ground level, which will accelerate spring growth.

Keep in mind that the process of deadheading your phlox plants may also afford them side shoots during the autumn season. This is actually a bonus if it occurs. In areas where winter cold fronts arrive later in the season, it is best to deadhead early. This will then allow for the phlox plant to grow and develop full flower heads by the end of the summer.

Although there are sterile phlox cultivar varieties that don’t really require this type of pruning, you must know that deadheading them will result in a much more attractive array of flowers. During this time, you can also fertilize your phlox plants and if you’re lucky enough, you could be surprised with a second flush of dainty blooms. For these reasons, knowing when does creeping phlox blooms will keep you a step ahead with your plant maintenance strategies.

Varieties of Phlox that Bloom All Summer and Spring

  • Creeping phlox.  This is the most common and is planted in many homes.  Creeping phlox is called so because it grows close to the ground, crawling and spreading.  It blooms approximately 6 weeks into the spring and the early part of summer in all the zones it grows.  You can propagate it by transplanting portions to the areas where you wish to grow it.  It grows slowly taking a long time to fill a large space.
  • Tall Phlox.  This variety grows anywhere from 10 inches to 4 feet high.  Tall phlox blooms in summer that is July and August.  There are exceptions of tall phlox that do not bloom in summer.  Astoria and Intensia phlox bloom beautifully into late fall and through winter in very cold climates.  Astoria grows up to about 24 inches and Intensia reaches around 14 inches tall.

When and Where to Plant Phlox

Plant phlox immediately after you receive it to avoid damage to sensitive young plants. Plant it either in spring or fall.

Planting in Fall.  Plant your phlox a few weeks before your first frost falls.  You can keep the plants cool on a deck for a few days until it’s the best time to plant.  But do not let the roots dry out before you plant.

Planting in Spring.  If your phlox plant arrives in spring, keep it moist in the container until the ground is ready for planting.  Hold off the spring planting until the ground is easy to work on and the soil is free from melted snow and ice.

Growing Conditions for Phlox Flower

Phlox is a low-maintenance plant but it requires the right growing conditions to thrive.

  • Light.  Both varieties of phlox thrive in full sun.  The garden phlox requires both sun and a little shade particularly in the south to thrive.
  • Soil.  Though phlox is tolerant to most garden soils, it does well in well-drained soils, especially in the Northern areas where the snow drains slowly.  Waterlogged, damp spring soil can cause root rot in the plants killing them.  Use compost or peat moss added to the garden soil to improve drainage and create a better growing environment.
  • Spacing.  Tall Phlox should be planted about 18 inches apart while creeping phlox planted about 2 feet apart.  If you plant them too close they are attacked by mildew. Giving them enough room for air circulation is the cure for mildew.

Once planted in these right growing conditions, you will realize that both varieties will gradually increase and join together to form a large grouping of phlox.  The creeping variety creates a carpet or mat-like formation on the ground.
