Phlox FAQ

What Is Phlox?

"Phlox" refers to a genus of about sixty-eight species of flowering plants in the family Polemoniaceae. They are native to North America, with one species found in Siberia. Phlox plants are herbaceous and can be annuals or perennials. They typically have oval or linear leaves and produce clusters of star-shaped flowers in a variety of colors, including white, pink, purple, red, and blue. Many phlox species are fragrant.

Here are some of the most common types of phlox:

Garden phlox (Phlox paniculata): This is the most popular type of phlox for gardens. It is a tall-growing perennial that can reach up to four feet in height. Garden phlox blooms in midsummer to early fall and produces large clusters of fragrant flowers.
Creeping phlox (Phlox subulata): This is a low-growing perennial that is often used as a groundcover. It grows to only about six inches in height and blooms in the spring. Creeping phlox produces mats of colorful flowers that are attractive to butterflies and hummingbirds.
Drummond phlox (Phlox drummondii): This is an annual phlox that is easy to grow from seed. It grows to about twelve inches in height and blooms in midsummer to early fall. Drummond phlox comes in a wide variety of colors, including white, pink, purple, red, and blue.

Phlox are relatively easy to care for and are a good choice for beginner gardeners. They prefer full sun and well-drained soil. They are fairly drought-tolerant but will benefit from regular watering during hot, dry weather. Phlox are also relatively pest- and disease-resistant.

How Do I Plant Phlox?

Planting phlox can be a rewarding experience, bringing vibrant color and fragrant blooms to your garden. Here is a guide to help you get started:

When to Plant:

Spring: Ideal for most types of phlox, especially in colder climates. Plant after the last frost when the soil temperature is around 50°F (10°C).
Fall: A good option for warmer climates. Plant at least 6 weeks before the first frost to allow roots to establish.

Choosing a Location:

Sunlight: Most phlox varieties prefer full sun (at least 6 hours of direct sunlight daily) for optimal bloom production.
Soil: Phlox thrive in well-drained soil with good air circulation. Amend heavy clay soil with compost or sand to improve drainage.
Spacing: Leave enough space between plants for mature growth. Tall garden phlox need about eighteen inches, while creeping phlox prefer two feet.

Planting Steps:

Prepare the soil: Loosen the soil to a depth of 12-15 inches and mix in 2-4 inches of compost or aged manure. This improves drainage and provides nutrients.
Dig holes: Dig holes twice the size of the root ball (or seed depth for direct sowing).
Plant: Carefully remove the plant from its container (if transplanting) and loosen the roots gently. Place the plant in the hole, ensuring the crown (where the stems meet the roots) sits slightly above soil level.
Backfill and water: Fill the hole with soil, tamp it down gently, and water deeply to settle the soil around the roots.

Additional Tips:

Mulch around the plants with a 2-inch layer of organic material like bark chips or straw to retain moisture and suppress weeds.
Water regularly, especially during hot, dry weather. Aim for about one inch of water per week.
Deadhead spent blooms to encourage further flowering.
Divide established phlox every 3-4 years to maintain vigor and prevent overcrowding.

Seed Sowing:

Some varieties, like Drummond phlox, can be directly sown in the garden after the last frost.
Follow seed packet instructions for specific spacing and depth.
Keep the soil moist until seedlings emerge.

Remember, specific needs may vary depending on the type of phlox you choose, so consulting a plant guide or local nursery for additional information is always helpful.

Enjoy planting your phlox and watching them flourish!

Are There Any Common Pests Or Diseases That Affect Phlox?

Unfortunately, no plant is completely pest and disease-proof, and phlox are no exception. While generally resilient, they can occasionally face some challenges. Here are some of the most common pests and diseases that can affect phlox:

Pests:

Phlox bugs: These bright red and black bugs suck sap from leaves and buds, causing stippling, yellowing, and stunted growth. They are particularly fond of garden phlox and can cause significant damage if left unchecked.
Leafhoppers: These tiny, jumping insects also feed on sap, leaving behind similar stippling and yellowing symptoms. They can also spread diseases between plants.
Spider mites: These tiny pests thrive in hot, dry weather and can quickly cover the undersides of leaves with their webbing. They feed on plant juices, causing leaves to turn yellow, bronze, or drop prematurely.
Thrips: These slender insects feed on flowers and buds, causing them to distort or become discolored. Thrips can also be vectors for plant viruses.

Diseases:

Powdery mildew: This fungal disease appears as white, powdery patches on leaves and stems. It thrives in cool, humid conditions and can stunt growth and reduce flowering.
Leaf spot: This fungal or bacterial disease causes brown or tan spots on leaves, which can eventually drop prematurely.
Root rot: This fungal disease attacks the roots, causing plants to wilt and die. It is most common in poorly drained soil or conditions with excessive moisture.

Controlling Pests and Diseases:

The best approach is to focus on prevention:

Provide good air circulation: Avoid overcrowding plants and ensure proper spacing.
Water correctly: Water deeply at the base of the plant, avoiding overhead watering that can spread fungal diseases.
Mulch around plants: A layer of organic mulch helps retain moisture and suppress weeds, which can harbor pests.
Encourage beneficial insects: Ladybugs, lacewings, and other beneficial insects help control pest populations naturally.
Practice good sanitation: Remove and destroy infected plant material promptly.

If pests or diseases become a problem, several organic and conventional control methods are available. Always consult a reputable source or gardening expert for specific recommendations based on your location and the severity of the infestation or disease.

By staying vigilant and responding appropriately, you can help your phlox plants thrive and bring vibrant color and fragrance to your garden throughout the season.

Is Phlox Invasive?

Whether phlox is invasive depends on the specific type and your location. Here is a breakdown:

Non-invasive: The most popular types of phlox, like garden phlox (Phlox paniculata) and creeping phlox (Phlox subulata), are not considered invasive in most regions. They spread modestly within their designated area and generally do not threaten native plants or ecosystems.
Invasive Lookalike: Be aware of Dame's rocket (Hesperis matronalis), which closely resembles phlox but is highly invasive. It has four petals instead of five and belongs to a different plant family. Dame's rocket can quickly spread and displace native vegetation.

Location-Specific Concerns:

Certain Varieties: Some less common phlox varieties, like Carolina phlox (Phlox pilosa), may be invasive in specific regions. Check with your local gardening authorities or experts to determine if any phlox types are considered invasive in your area.
Factors Influencing Invasiveness: Even non-invasive phlox can spread more aggressively in certain situations, such as disturbed soil or lack of competition. Proper planting and care practices can help prevent unwanted spreading.

When Is The Best Time To Divide Phlox Plants?

The best time to divide phlox plants depends on a few factors, including the climate in your area and the specific type of phlox you are growing. Here is a breakdown to help you decide:

General Recommendations:

Spring: This is the ideal time for dividing most phlox in cold and temperate climates. Aim to do it just as new growth begins to emerge, typically in early spring after the last frost. This gives the divisions enough time to establish before winter arrives.
Fall: In warmer climates with mild winters, dividing phlox in late summer or early fall (August to September) can also be successful. Make sure to do it at least 6 weeks before the first expected frost and mulch them well before winter sets in.

Variety-Specific Considerations:

Garden Phlox (Phlox paniculata): Spring division is generally preferred but fall division can also work in warmer climates.
Creeping Phlox (Phlox subulata): Can be divided any time during the year, but spring or fall are most ideal.

Drummond Phlox (Phlox drummondii): This annual phlox does not need dividing.

Signs Your Phlox Needs Dividing:

Crowded Plants: If your phlox plants are becoming overcrowded, the center may no longer flower, and overall growth may be stunted. Division will help rejuvenate them.
Reduced Blooming: Fewer flowers than usual can be a sign that the plants need more space and nutrients.
Doughnut Shape: If your phlox plants are growing in a circular shape with a dead patch in the center, it is a clear indication they need dividing.

Remember:

Avoid dividing phlox on hot, sunny days. Choose a cool, cloudy day or early morning/evening.
Water the plants thoroughly before and after dividing.
Ensure each division has healthy roots and at least 3-5 shoots.
Plant the divisions immediately in well-drained soil at the appropriate depth.

By understanding the best timing and considering your specific type of phlox and local climate, you can successfully divide your phlox plants and enjoy their vibrant blooms for many years to come!
