Phloxes are a low-maintenance perennial that can thrive in a variety of conditions. They're perfect for gardeners of all levels.

Phloxes are native to North America, with over 60 species to choose from. They come in a range of colors, including pink, purple, white, and red.

To grow phloxes, choose a location with well-draining soil and full sun to partial shade. They're also drought-tolerant, but will perform best with regular watering.

Some phloxes can grow up to 4 feet tall, while others stay compact and only reach 1-2 feet in height.

About Phloxes

Phloxes are low-maintenance flowers that come in a variety of colors and bloom times.

Phloxes are available in a range of colors, including red, pink, blue, white, and lavender. I've seen them thrive in well-drained soil and partial shade, making them a great choice for gardeners with limited space.

Some phlox species, like P. subulata, are compact and only grow to 6 inches tall, while others, like P. divaricata, can reach heights of 2-4 feet. This diversity makes phloxes suitable for a range of garden designs.

The spring-blooming phlox species, such as P. subulata and P. divaricata, are great for adding early color to your garden. Their vibrant blooms can last for several weeks, providing a beautiful display of flowers.

Here are some common phlox species and their characteristics:

Phloxes are also relatively low-maintenance, requiring only occasional watering and pruning to keep them looking their best.

How to Plant

Planting phlox is a bit more involved than just sticking a stick in the ground, but don't worry, it's still pretty straightforward. First, choose a spot that gets the right amount of sunlight for your specific type of phlox - some love full sun, while others prefer partial shade.

Soil is also super important. Phlox prefer soil that's nutrient-rich and evenly moist, but they don't like to sit in wet soil, so make sure to loosen it up with a garden fork or tiller to about 12 to 15 inches deep. This will give the roots room to breathe and help prevent root rot.

Mix in a 2- to 4-inch layer of compost to improve soil consistency and fertility. This will give your phlox a great head start on growing strong and healthy.

If you're planting phlox in the spring, wait until the threat of frost has passed. If you're planting in the fall, do it at least a month before your first frost.

You can plant phlox from cuttings or transplants, which is generally easier than trying to grow them from seed. Space plants according to their mature size, and if you're transplanting a plant from a pot, dig a hole about twice the size of the pot's diameter.

When you've got your phlox in the ground, fill in around the root ball, and remember to water it thoroughly. This will help the roots settle in and get established.

Types of Phloxes

Phloxes are incredibly versatile, and there are many varieties to choose from. One of the most popular species is Phlox subulata, also known as creeping phlox or moss phlox.

Creeping phlox is a low-growing species that works well as a ground cover, spreading slowly in mounds that get 4-6 inches thick. It's particularly stunning when allowed to drape over a rock wall, creating a waterfall of color.

There are also two other low-growing species to consider: Phlox stolonifera and Phlox divaricata. Phlox stolonifera has oval-shaped leaves and produces flowers on stems that rise 6-10 inches above the foliage, preferring a shadier growing site with rich, evenly moist soil. Phlox divaricata, also known as woodland phlox or blue phlox, produces bluish flowers in early spring and prefers partial to full shade and moist, rich soils.

Here are some of the most popular phlox species to try:

  • Phlox subulata (Creeping phlox or moss phlox)
  • Phlox stolonifera (Creeping phlox or moss phlox)
  • Phlox nivalis

Dividing Like a Pro

Dividing phlox in early spring is the best time to do so, as the plant is coming out of dormancy and you can clearly see how large they have spread.

You can increase your stock of phlox plants by dividing them, and it's a great way to give them a fresh start.

To divide phlox, dig down and lift one piece of the plant out and plant in another area, making sure to give the new plant enough space to grow.

The ideal time to divide phlox is when the plant is coming out of dormancy, which is typically in early spring.

Plant the new phlox plants 60cm apart, so they have plenty of room to spread out and grow.

If you're looking to propagate phlox, you can also take root cuttings in winter, before they start to send up their spring shoots.

By dividing and replanting phlox, you'll be rewarded with new plants that will go on to flower in summer.

Here are some low-growing phlox species to consider:

Growing: Problem Solving

Growing phlox requires some problem-solving skills, especially when it comes to their watering needs. Phlox don't like drought and will show it by wilting in dry weather.

Watering in the morning is a good idea, as this allows the roots to get a good soaking before the heat of the day sets in. This can make a big difference in keeping your phlox healthy and thriving.

Powdery mildew can be a problem in hot, humid weather, especially if your phlox is growing in partial shade. Improving air circulation by thinning the plants in early spring can help prevent this issue.

Growing from Seed

Growing from seed is a great way to start your phlox journey. In warmer areas, sow the seeds in fall, while in colder areas, start them about two months before your last spring frost date.

Annual phlox will germinate in about a week, while perennial phlox takes up to a month. Keep the seeds covered and in the dark to help them germinate.

Place the seed tray in a black garbage bag to keep it dark, and make sure to keep the seeds moist. Once they germinate, move them to full sun.

The perennial phlox seedlings can be transplanted into the garden when they're large enough to handle easily. They'll grow slowly the first year and typically don't bloom until year two.

Good Pairings

Growing phloxes is a great way to attract pollinators to your garden. There are hundreds of native flowers, shrubs, and trees that make for great phlox pairings.

You can pair phlox with native flowers, shrubs, and trees to have something blooming throughout the growing season. This will keep pollinators like bees and butterflies happy and busy.

One goal of native gardening is to have something blooming throughout the growing season. This is especially important for pollinators that rely on these flowers for food.

Pairing phlox with other native plants can create a beautiful and diverse garden. With so many options to choose from, you can experiment and find the perfect combination for your garden.

By choosing native plants, you'll also be supporting local ecosystems and biodiversity. This is a win-win for both you and the environment.

Care and Maintenance

To keep your phlox plant thriving, divide it every three or four years in early spring, replanting the clumps around 60cm apart. This will prevent congestion and promote healthy growth.

Signs that your phlox needs dividing include fewer flowers and a sparse centre. Don't worry, it's an easy process that will give your plant a new lease on life.

Deadheading immediately after flowering can actually lead to more phlox flowers produced from side shoots in autumn. It's a clever trick that will keep your plant blooming all season long.

How to Care for

To keep your phlox plant growing well, divide it every three or four years in early spring, replanting the clumps around 60cm apart. This will prevent it from becoming congested and promote healthy growth.

Fewer flowers and a sparse centre are signs that your phlox needs dividing. I've noticed this in my own garden, and it's amazing how a simple division can revitalize the plant.

Deadheading immediately after flowering can result in more phlox flowers produced from side shoots in autumn. This is a great way to extend the blooming season and keep your garden looking its best.

Plants rarely need staking, but a windy site may require some extra support. I've had to stake my phlox in the past when it was exposed to strong gusts, and it made a big difference.

To stagger flowering or delay it, try the 'Chelsea Chop' on your plants. Cut some or all of the stems back by half in late May, and you'll see a delay of about a month in the blooming process.

Remove

Removing dead or dying phlox plants is an essential part of their care and maintenance. This helps prevent the spread of disease and encourages healthy growth.

Deadheading, the process of removing spent flowers, can also be beneficial. It encourages the plant to produce more blooms and can improve its appearance.

If you're removing a large amount of phlox, consider dividing the roots to propagate new plants. This can be a great way to share phlox with friends or expand your garden.

To remove dead or dying phlox, carefully dig around the plant with a fork to avoid damaging the surrounding soil. Gently lift the plant out of the ground and remove any dead or dying stems.

Some phlox varieties, such as Phlox subulata, can be quite invasive and may need to be removed regularly to prevent them from taking over other areas of your garden.
