Asian Ponysfoot, scientifically known as Dichondra micrantha or Dichondra repens, is a popular groundcover prized for its dense, carpet-like growth and vibrant green, kidney-shaped foliage. This low-growing perennial spreads quickly by rooting stems, creating a lush lawn substitute where traditional turfgrasses may struggle. Its appeal lies in its soft, uniform texture and ability to thrive in areas that receive less intense sunlight.
Preparing the Planting Site
Successful establishment of Asian Ponysfoot begins with careful preparation of the soil and selecting the correct site conditions. This plant performs best in a rich, well-draining medium, preferring a slightly acidic to neutral pH range of 6.0 to 7.5. Heavy clay or poorly draining soils should be amended with organic matter like compost to ensure excess water does not linger and cause root problems.
Choosing the right light exposure is necessary for the plant’s health and appearance. While it tolerates a wide range, Asian Ponysfoot flourishes in full sun to partial shade. In regions with intense, hot summers, afternoon shade is beneficial to prevent the foliage from scorching and to reduce moisture stress.
Planting can be achieved through seed, plugs, or sod, with springtime being the optimal period once night temperatures consistently exceed 50°F. If sowing seed, they should be lightly pressed into a finely raked seedbed, as they require light for germination, and then kept consistently moist. For plugs or established plants, spacing them approximately 6 to 12 inches apart will allow the runners to quickly fill in the area and create a dense mat.
Essential Ongoing Care
Once the Asian Ponysfoot has become established, the focus shifts to a maintenance regimen that supports its dense, creeping growth. Proper watering involves deep, infrequent irrigation rather than frequent, shallow sprinklings. The goal is to allow the top layer of soil to dry out slightly between waterings, as consistent saturation makes the plant susceptible to fungal diseases.
The plant benefits from regular feeding during the active growing season to maintain its lush green color and vigor. A balanced fertilizer, such as a 10-10-10 N-P-K ratio, is appropriate for overall health. Many growers recommend a high-nitrogen fertilizer, applied lightly once every two to three weeks, or a slow-release option applied less frequently.
Nitrogen is especially important for promoting the leafy, dense growth characteristic of a good groundcover. Applying the fertilizer at a rate of roughly 0.5 to 1 pound of nitrogen per 1,000 square feet monthly is a common practice. If the plant is used as a lawn substitute, mowing is optional but can be done to encourage a finer, more uniform texture. Maintaining a cutting height of 1.5 to 2 inches every two weeks during the summer helps to achieve this manicured appearance without causing undue stress or scalping.
Identifying and Managing Problems
Asian Ponysfoot, while generally hardy, can be affected by specific pests and environmental conditions that require targeted management. Common insect pests include slugs and snails, which chew irregular holes in the soft foliage, particularly on young plants. Controlling these mollusks often involves applying baits containing metaldehyde or iron phosphate around the affected areas.
Other pests, such as flea beetles, aphids, and cutworms, may also feed on the leaves and stems. Flea beetles skeletonize the leaves, which appears as browning with gnawed lines. Managing these insects typically requires confirming their presence and then applying an appropriate insecticide only when the infestation is severe enough to cause significant damage.
Fungal diseases, including root rot and powdery mildew, are primarily linked to poor drainage and overwatering. Root rot is a common issue in poorly draining soils, causing the plant to yellow and decline. Improving soil aeration, correcting watering practices, and ensuring the site is not waterlogged are the most effective corrective measures. The plant is generally resilient but may suffer environmental stress when exposed to heavy foot traffic, which can break the creeping stems and damage the dense mat. While it can tolerate cold temperatures down to around 20–25°F, it will go dormant and may experience some browning in colder climates, but the roots usually survive to regrow in the spring.
