Starting a new patch of this reliable groundcover begins with careful planning and an understanding of how the plant establishes itself in the soil. You should approach the planting process with patience, knowing that a well-installed plant will form a thick, beautiful mat within just a couple of seasons. Proper installation is the most critical phase of the plant’s life, as it determines how quickly the roots can tap into the local environment for moisture and nutrients. By following professional planting protocols, you can ensure a high success rate and a seamless integration into your existing garden design.
Timing and site preparation
The best time to plant is typically in the early spring or early autumn when temperatures are mild and natural rainfall is more consistent. You should avoid planting during the heat of mid-summer, as the young plants will struggle to establish roots while simultaneously dealing with high transpiration rates. If you plant in the spring, the species has the entire growing season to build a strong root system before the winter frost. Alternatively, autumn planting allows the plant to settle in during the cooler months, often leading to a more vigorous start the following year.
Preparing the site properly is a task that pays dividends for years to come by providing the best possible start for your new arrivals. You should begin by removing all existing weeds, especially perennial ones with deep taproots that could grow up through your groundcover later. Loosen the soil to a depth of about six to eight inches to ensure that the delicate new roots can penetrate easily and find the moisture they need. Adding a layer of organic compost to the area will provide a nutrient-rich foundation and improve the soil structure for better drainage.
The spacing of your plants will depend on how quickly you want the area to be completely covered by the green foliage mat. You should generally space the individual plants about ten to twelve inches apart for a balanced growth rate that avoids overcrowding too early. Closer spacing will result in faster coverage but will require more initial plant material and might lead to increased competition for resources. Wider spacing is more economical but will require more diligent weeding during the first two seasons until the canopy closes completely.
Soil moisture should be checked and adjusted before any plants are actually put into the ground to prevent root shock during the transition. You should water the planting area thoroughly a day or two before you begin to ensure the soil is hydrated but not overly saturated or muddy. If the soil is very dry at the time of planting, it can pull moisture away from the root ball, causing the plant to wilt immediately. A well-hydrated planting site provides a welcoming environment that encourages the roots to move out from the nursery soil into the native garden earth.

Planting steps and techniques
When you are ready to plant, handle each specimen with care to avoid damaging the crown or the emerging runners that are vital for future growth. You should dig a hole that is slightly wider and deeper than the current root ball of the nursery plant. Place the plant in the hole so that the crown—the point where the stems meet the roots—is level with the surrounding soil surface. Planting too deeply can lead to crown rot, while planting too shallowly can cause the roots to dry out and die.
Gently backfill the hole with the amended soil, pressing down lightly with your hands to remove any large air pockets around the roots. You should be careful not to pack the soil too tightly, as this can impede root growth and limit the amount of oxygen reaching the plant. Watering each plant immediately after it is in the ground is essential for settling the soil and ensuring good contact between the roots and the earth. This initial irrigation should be deep and thorough to saturate the entire root zone of the new planting.
Applying a light layer of mulch around the base of the new plants will help conserve moisture and suppress the growth of competing weeds. You should use a fine-textured mulch like shredded bark or compost that won’t smother the small plants but will still provide protective cover. Keep the mulch a small distance away from the stems themselves to prevent moisture from sitting against the crown, which can encourage disease. A good mulching strategy is one of the easiest ways to increase the survival rate of newly installed groundcovers.
During the first few weeks after planting, you must monitor the site daily to ensure that the young plants are adapting well to their new home. You should look for any signs of stress, such as yellowing leaves or wilting, which might indicate a need for more water or a bit of temporary shade. If a plant seems to be struggling, check the soil moisture and ensure that it hasn’t been disturbed by animals or heavy rain. Consistent care during this establishment phase is the key to creating a resilient and long-lasting garden feature.

Division of established clumps
Dividing existing plants is the most common and effective way to propagate this species and expand your garden coverage for free. You should look for healthy, well-established clumps that have grown for at least two or three years before attempting to divide them. The best time for this process is in the early spring just as the new growth begins to emerge from the center of the plant. Dividing in the early morning or on a cloudy day will help reduce moisture loss from the exposed roots during the procedure.
To begin the division, use a sharp spade or garden fork to carefully lift the entire clump out of the ground with as much of the root system as possible. You should then gently pull the clump apart by hand or use a sharp knife to cut it into smaller sections, ensuring each piece has several healthy leaves and a good amount of roots. Large clumps can often be divided into three or four separate plants that are ready to be moved to their new locations. Keep the divided sections in a shaded spot and keep the roots moist until they are back in the soil.
Replanting the divisions follows the same basic steps as planting new nursery stock, with an emphasis on immediate watering and soil contact. You should prepare the new planting holes in advance so the roots are not exposed to the air for longer than necessary. Firm the soil around the new divisions and provide a light mulch to help them settle into their new environment quickly. Dividing not only gives you more plants but also rejuvenates the original mother plant by giving it more space and fresh soil to grow into.
Post-division care is crucial because these new plants have smaller root systems and are more vulnerable to environmental changes for the first few months. You should keep the soil consistently moist but never waterlogged to encourage rapid root development in the new sites. Avoid applying heavy fertilizers during this time, as the plants need to focus on establishing roots rather than producing a lot of top growth. With a little extra attention, these divisions will soon grow into lush, independent plants that look like they have always been there.
Alternative propagation methods
While division is the easiest method, you can also propagate this plant by utilizing the natural runners it produces during the growing season. You should look for long stems that have small plantlets forming at the nodes where they touch the soil. You can encourage these plantlets to root more quickly by gently pressing them into the earth and pinning them down with a small piece of wire. Once the new plant has developed a strong root system of its own, you can simply snip the connecting stem and move the new plant elsewhere.
Collecting and sowing seeds is another way to propagate the species, though it is a much slower process than using divisions or runners. You should harvest the small seeds from the spent flower heads in early summer once they have turned dark and dry. Sow the seeds in a tray filled with high-quality seed-starting mix and keep them in a cool, shaded area with consistent moisture. Germination can be irregular, so you must be patient and keep the environment stable until the small seedlings are large enough to be handled.
Growing from cuttings is sometimes possible, though it is less common for this specific groundcover because the runners are so effective. You should take small sections of healthy stems with a few leaves and place them in a moist potting medium under a humidity dome. Keep the cuttings in a bright but indirect light source and check the moisture levels regularly to prevent them from drying out or rotting. If successful, the cuttings will develop roots within a few weeks and can be transitioned to individual pots before being planted in the garden.
Successful propagation requires a bit of experimentation to find which method works best for your specific garden conditions and available time. You should keep records of when you tried each method and what the success rates were to improve your skills for future projects. Whether you use division, runners, or seeds, the goal is always to create healthy new plants that can contribute to the beauty of your landscape. Propagation is a rewarding part of gardening that allows you to multiply your favorite plants and share them with the gardening community.
