How to Propagate Phlox: A StepbyStep Guide
How to Propagate Phlox?
To propagate phlox, there are three main methods: seed, cuttings, and division.
Division is the easiest and quickest method.
In the spring or fall, the plant can be dug up and the root ball separated into new clumps.
These new clumps can then be transplanted into a location with rich, moist, well-drained soil.
Water and fertilize the newly divided phlox plants, ensuring they receive 5 hours of direct sunlight per day and one inch of water per week.
Creeping phlox can also be propagated through division, stem cuttings, or rooted stems.
For stem cuttings, take them in summer or fall and use a fast-draining growing medium.
The cuttings should be planted 4 inches into the soil and kept moist in bright, indirect light until rooted, which usually takes four to six weeks.

Did You Know?
1. Phlox plants have been cultivated for centuries, with evidence of their cultivation dating back to ancient civilizations such as the Assyrians and Egyptians.
2. Propagation of phlox can be done through various methods, such as division, stem cuttings, and even seed collection. However, stem cuttings tend to be the most successful method for propagating specific cultivars.
3. Phlox plants are known to attract butterflies and hummingbirds with their vibrant and fragrant flowers, making them a popular choice for gardeners looking to create a wildlife-friendly environment.
4. Although phlox plants are generally low-maintenance, they can be prone to powdery mildew, especially in humid conditions. Applying a fungicide or planting resistant varieties can help prevent this common fungal disease.
5. Some phlox varieties, such as creeping phlox (Phlox subulata), are excellent for groundcover and erosion control due to their spreading growth habit and ability to thrive in poor soil conditions.
Propagation Methods For Phlox
Phlox, also known as “flame flowers,” can be propagated using three different methods: seed, cuttings, and division. Each method has its own advantages and challenges, but all can be successful when done correctly. Depending on your preference and the resources available, you can choose the propagation method that suits you best.
Division: The Easiest And Quickest Method
If you are looking for the quickest and easiest way to propagate phlox, division is the way to go. This method involves digging up an existing phlox plant and separating the root ball into new clumps. The best time to divide phlox is in the fall or early spring.
To start the division process, carefully dig up the plant, making sure to keep the root ball intact. Separate the root ball into smaller clumps, ensuring that each new division has a healthy amount of roots and shoots. It is crucial to handle the roots with care to avoid damaging them.
Once you have divided the phlox, choose a location with rich, moist, and well-drained soil for transplantation. Dig holes that are the same size as the root clumps and place the divisions into the holes, making sure to keep them at the same depth they were previously planted.
After transplanting, water the newly divided phlox plants thoroughly. It is essential to keep the soil moist, especially during the initial establishment period. Provide the newly divided phlox with around 5 hours of direct sunlight per day and about one inch of water per week to ensure their healthy growth.
Phlox Cuttings In The Spring
Another effective method for propagating phlox is through cuttings. Cutting phlox can be done in the spring before the plant starts to bloom. This method involves taking stem cuttings from a healthy phlox plant and encouraging them to root and grow into new plants.
To take cuttings, carefully select the stems that are several inches long and have several leaves. Using sharp and clean cutting tools, make a clean cut just below a leaf node. Avoid taking cuttings that already have flowers, as they require a large amount of energy from the plant.
- Select stems that are several inches long and have several leaves
- Make a clean cut just below a leaf node
- Avoid taking cuttings with flowers
Length And Condition Of Cuttings
The length and condition of the cuttings are crucial for the successful propagation of phlox. Aim for cuttings that are several inches long, as shorter cuttings may struggle to establish roots. Ensure that each cutting has at least one leaf, as they play a vital role in the growth process.
Before planting the cuttings, it is advisable to remove any flowers or flower buds. This allows the plant to focus its energy on root development rather than flower production. If desired, you can use a rooting hormone to speed up the process of establishing roots. Apply the rooting hormone to the cut end of the stem according to the instructions on the packaging.
- Aim for several inches long cuttings
- Ensure each cutting has at least one leaf
- Remove flowers or flower buds before planting
- Consider using a rooting hormone for faster root development
Propagation In Soil Or Water
Phlox cuttings can be propagated using either soil or water.
In soil propagation, plant the cuttings in a fast-draining growing medium, such as a mixture of peat, coarse sand, and perlite. Make a hole in the planting medium with a pencil or a similar tool and insert the cutting, ensuring that at least two-thirds of the stem is buried in the soil.
For water propagation, place the cuttings in a container filled with water, making sure that the nodes are submerged. Change the water regularly to prevent the growth of algae or bacteria that can harm the cuttings.
Regardless of the propagation method you choose, it is important to provide the cuttings with the right conditions. Keep the planting medium or water moderately moist and place the container in an area with bright but indirect light.
To maintain adequate moisture levels, cover the container with a clear plastic bag or use a propagator. However, remember to remove the plastic bag daily to prevent fungal build-up, which can lead to rotting of the cuttings.
Seed Collection And Planting Outdoor
If you prefer to propagate phlox from seeds, you can collect them from existing plants. The ideal time to collect seeds is in the fall or spring. Once you have gathered the seeds, they need to undergo a process known as stratification before planting.
Stratification involves storing the seeds in the refrigerator for about a month. This cold treatment helps break the seed coat dormancy and promotes more successful germination. After the stratification period, you can plant the seeds outdoors, directly in the ground or in seed trays.
Choose a location with well-draining soil and partial sun for optimal growth. Carefully follow the instructions on the seed packet regarding planting depth and spacing. Ensure that the soil is kept consistently moist after planting until the seeds germinate.
In summary, propagating phlox can be achieved through various methods, including division, cuttings, and seeds.
- Division is the quickest and easiest way to produce new phlox plants.
- Cuttings and seed propagation require more patience and attention.
By following the steps mentioned above, you can successfully propagate phlox and enjoy an abundance of these beautiful flowers in your garden.
Frequently Asked Questions
How do you divide and transplant creeping phlox?
When dividing and transplanting creeping phlox, it is best to do so in the spring when new growth starts. Carefully dig up the plants, ensuring that each clump is separated into sections with a sharp knife. Remember to include 2 or 3 shoots and a portion of the root system in each division. Once divided, promptly replant the sections to ensure successful transplantation.
How do you propagate phlox seeds?
To propagate phlox seeds, start by filling trays, punnets, or jiffy pots with a high-quality seed-raising mix or use soil starter pellets. Sow the phlox seeds about 3mm deep into the soil and ensure that the soil remains constantly moist, avoiding both excess wetness and dryness. With a soil temperature of 18-20°C, the seeds should germinate within approximately 14-21 days. Patience and proper care in maintaining the ideal temperature and moisture levels will promote successful propagation of phlox seeds.
How do phlox reproduce?
Phlox reproduces both through cuttings and transplants, making it easier to cultivate them compared to growing from seeds. While established plants naturally spread through seed dispersal in the garden, it is recommended to space the plants based on their mature size for optimal growth and arrangement.
Can phlox grow from cuttings?
Yes, phlox can be propagated through cuttings. One method is to carefully take root cuttings during the winter months, before the plants begin to produce new shoots in the spring. These cuttings can be taken from plants either dug up from the garden or from pot-grown plants. Once the cuttings are potted, they can be placed in a cold frame where they will have the opportunity to develop roots and grow into new young plants by midsummer. This method allows for the successful propagation of phlox through cuttings, offering a way to expand one’s phlox collection and create new plants.
