How to Prune Phlox
Pruning and Caring for Phlox
It doesn’t matter if the Phlox is annual or perennial, watering when the ground is dry is all that is required for proper care.
Phlox cultivated in pots, garden boxes, or containers needs more frequent watering.
Annual Phlox
- Among Phlox, the drummondii is the most well-known variety.
- It prefers well-drained, fertile soil in full sun.
- During dry spells, make sure to give it plenty of water.
Perennial Phlox
Despite the wide range of Phlox species and types, they all have a common trait: a penchant for direct sunlight.
- Always look for areas that are exposed to the sun for at least a few hours a day, if not more.
- Check to see if your soil is rich enough to support lovely blooms.
- fertilizer for flowering plants should be added to the soil in spring.
- Regularly remove flowers that have faded or wilted.
Phlox in winter
Perennial phlox will return each year, but cutting back the foliage after the first frost is preferable. If it is left on the plant, it will shortly turn black. Apply a thick layer of mulch made from dead leaves.
Annual Phlox is easy to remove because it doesn’t grow back year after year.
Where to Plant Phlox Garden
Perennial gardens
With other perennials that bloom in the spring and summer, such lilies, bee balm, rudbeckia and Shasta daisies to name a few, phlox is an ideal companion.
Tall Phlox can be used as a backdrop for smaller plants in flowerbeds.
Creep phlox care may be quite intriguing, as can this creeping Phlox Michigan.
Cutting Gardens
The sturdy and long stems of the gardening phlox make it simple to arrange other flowers like dahlias and lilies in a vase, where they may compliment and support them.

As soon as they’re bud-stage, cut off the stems. This will help them last longer in the vase.
How to Plant a Phlox Garden
- Mix in several handfuls of compost and approximately 14 cup of granular all-purpose fertilizer to loosen the soil to a depth of 13 inches (follow package directions).
- When planting, make sure the crown (the point where the roots and trunk meet) is level with the ground.
- Soil and water should be applied generously to the roots.
Keep it Clean

Pruning phlox is as simple as using your fingers and a pair of bypass shears. Before you prune, disinfect the shears to prevent the spread of disease and insects. Use an isopropyl alcohol-soaked cloth to clean your pruning shears before you begin and after you finish pruning to get rid of fungus spores and disease germs. You should wash your hands before handling phlox and wear clean gardening gloves while doing so to prevent the spread of plant disease A lack of adequate garden cleanliness can quickly spread fungal diseases among phlox plants, which are particularly vulnerable.
Thin it Out
Demand Media / Jeanne Studio
Phlox paniculata (garden phlox), which grows to a height of 2 to 4 feet and is hardy in USDA zones 4 through 8, benefits from early trimming. When the plant reaches a 6-inch height, sterilized pruning shears can be used to remove all but five or six of the strongest stems. Thinning helps the remaining stems to develop and flower beautifully, and it also helps to keep powdery mildew at bay later in the season by increasing air circulation. After you’ve thinned the plant, squeeze each stem just above the topmost developing bud with your thumb and fingertips. Plants with fuller, bushier flowers can be achieved by pinching the stems
Cut it Back

To encourage new growth and blossoms, some phlox cultivars need to be deadheaded to prevent seed production. Additionally, it cleans the plants to keep them looking their best and to keep mildew at bay. Trim off garden phlox’s dead flower stems at their bases immediately after the plant finishes blooming. As soon as the flowers have faded, it is necessary to prune back the shorter types, such as the hardy USDA zones 4 through 8 creeping phlox, as well as the hardy USDA zones 2 through 8 moss phlox (Phlox subulata). Reduce the height of the entire plant by a third to a half.

Reduce the height of the entire plant by a third to a half.
Planting tips for Phlox
- To foster new growth and flowers, some phlox kinds need to be deadheaded, which means removing existing flowers from the plant. Plants benefit from a fresher appearance and a reduction in mildew. Immediately following blooming, cut the dead flower stems of garden phlox back to their rootstocks. Phlox subulata (Phlox subulata) and stoloniferous phlox (Phlox stolonifera), which are both hardy in USDA zones 2 through8, need to be trimmed back after they have finished flowering. Remove around a third to a half of the plant’s mature height by performing this procedure.
- Deadheading — removing old flowers — hinders seed production, which stimulates some phlox kinds to produce new growth and fresh blossoms. Additionally, it cleans the plants to keep them looking their best and prevent mildew growth. Immediately following blooming, cut the dead flower stems of garden phlox back to their rootstocks to avoid disease. Phlox subulata (Phlox subulata), hardy in USDA zones 2 through 8, and creeping phlox (Phlox stolonifera), hardy in USDA zones 4 through 8, must be pruned back after they finish flowering. Reduce the height of the plants by a third to a half.
What to expect
- During the growing season, Phlox needs about 2 inches of water every week.
- Maintaining a healthy appearance for the plant’s foliage is important, but avoid wetting the leaves.
- Weeds are discouraged and soil moisture is retained when compost or shredded leaf detritus is used as a mulch.
- Powdery mildew, a fungus, can harm garden phlox.
- Despite the fact that it poses no significant threat to the plant, this disease can cause the foliage to get covered in an unsightly white powder.
- Powdery mildew thrives in humid, warm climates, making it a major concern. Good ventilation should be encouraged in order to minimize the risk.
- Keeping the foliage as dry as possible can help lessen the risk of infection.
Thinning
The early thinning of Phlox paniculata (a 3 to 5 foot perennial garden phlox that thrives in USDA zones 4 to 8) encourages the plant to produce more flowers.
- Using a sterilized pruning shear, remove all but five or six of the plant’s strongest stems when it reaches a height of six inches.
- When the stems are thinned, the other stems become stronger and produce larger blooms. In the later part of the season, powdery mildew is less of a problem because of the better ventilation.
- Using thumb and fingers to pinch each stem just above the uppermost growing sprout once it has been thinned out.
- Plants with more flowers and a bushier appearance are the outcome of pinching the trunks of the plants.
Cut it back
- To encourage new growth and blooms on some phlox kinds, deadheading (removal of old flowers) is an effective way to prevent seed production.
- It also helps keep plants looking their best and preventing mildew.
- After the phlox has finished blooming, cut back the plant’s dead flower stalks at their base.
- Creeping Phlox is one of the many types of shorter Phlox (Phlox stolonifera). It is necessary to prune back hardy plants in USDA zones 2 through 8 and moss phlox (Phlox subulata), which are hardy in USD zones 5 through 10.
- Reduce the height of all plants by a third to a half.
Stop mildew
- Powdery mildew, the most prevalent disease of Phlox, can be avoided by pruning and cleaning up afterward.
- White powder covers the plant’s leaves and blossoms when powdery mildew is present. Eventually weakening and eventually killing the plant due to a lack of sunshine.
- Infected stems and leaves should be removed at any moment during the growth season in order to keep this disease from spreading further.
- After each cut, destroy mold spores by disinfecting your pruning shears, and wash your hands after handling sick Phlox.
- As soon as the leaves and pruning trimmings fall, rake them up to avoid the Phlox from becoming a breeding ground for mold spores.
- Phlox-infecting diseases and parasites.
- Snails and slugs, which feed on Phlox’s leaves, are the most harmful parasites.
- Powdery mildew can also affect phlox.
- Description and treatment of powdery mildew.
When and Where to Plant Phlox
You can plant the Phlox as soon as you receive it in the fall or spring, depending on the weather.
Light:
Vertical garden phlox may tolerate midday shade in the south, but both types of Phlox prefer full sun.
Soil:
- Well-drained soil is preferable, especially in northern places where spring snow is more likely to accumulate and take longer to melt.
- Dormant roots can be rotted by wet, soggy spring soil.
- Enhance the garden’s drainage and overall quality by incorporating compost or peat.
Spacing:
- While creeping, garden phlox has to be spaced about 19 inches apart. Three feet is the ideal height for phlox.
- The best way to prevent mildew growth on these plants is to provide them with lots of air circulation.
- As a result, the majority of the types currently on the market have been bred to be mildew resistant.
- You’ll see both species clump together over the next few years, with the Creeping variety generating a mat or carpet of Phlox in the process.
Fall planting:
It’s best to wait to plant the plants until it’s chilly enough to do so on the terrace in the fall, but don’t allow the roots dry up. You want to get them in the ground well before the first foot frost occurs.
In the spring, plant:
Similarly, if the plant is delivered in a spring container, make sure to keep it moist until you’re ready to plant it.
Spring planting should be postponed until the soil is clear of melting ice and snow and can be worked easily. In many circumstances, a one-inch layer of earth is the most convenient.
How to Prune Phlox: FAQs
When should I prune Phlox?
Remove faded or dead flowers to encourage reblooming in your plants. The first killing frost in the fall is the perfect time to trim back tall phlox to a height of 1 to 2 inches high. (Be sure to check the dates of your local frost). For healthy, disease-free plants, divide tall phlox every two or three years.
How do you maintain Phlox?
Keep the foliage dry by applying water to the earth rather than to it, and you’ll be keeping your phlox tree in good shape! To help the soil retain moisture, cover the plants with a 2- to 3-inch layer of mulch. After the flowers have faded, you should cut the stems of your garden phlox.
How do you Deadhead phlox?
- With a small pair of scissors, trim spent flower clusters as soon as the blooms begin to droop.
- Once the flowers have bloomed and no new buds have formed along the stalk, remove the entire flower spike. After decomposition, discard or compost the removed flower clusters and spikes.
Conclusion
When it comes to decorating your home, phlox provides an abundance of flair and grace. Always maintain your plant labeled and make sure it has all it needs for healthy development.
Planting a Phlox tree in your home is the greatest option in the long run. The effort required to maintain them is well worth it. Many times, these trees can be a tremendous aid in terms of aesthetics. Everything will be alright as long as you maintain them clean and avoid drying them out.
