Want a gorgeous, low-effort landscape? Pachysandra is your answer. This shade-loving superstar spreads quickly, suppresses weeds, and offers year-round greenery with minimal fuss.
What is Pachysandra?
Pachysandra, a Japanese spurge, is a beloved evergreen ground cover. It’s prized for its lush, dark green foliage, low maintenance needs, and ability to thrive in shady areas where grass struggles. Native to Japan, Pachysandra is hardy in USDA zones 4-8. It spreads through underground stems, forming a dense carpet that suppresses weeds and adds beautiful texture to your landscape.

-
Foliage: The leaves of ‘Green Carpet’ are smaller and more densely packed than standard Japanese Pachysandra. They retain the classic glossy, dark green color.
-
Growth Habit: ‘Green Carpet’ still spreads via underground rhizomes, but its growth is more controlled. It forms a dense, carpet-like mat without being as aggressive as some Pachysandra varieties.
-

Pachysandra Planting Tips
-
Location: Pachysandra thrives in full shade or partial shade. Avoid planting in areas with prolonged direct sunlight, especially during hot afternoons, as the intense sun can scorch the leaves and lead to browning. Ideal locations include under trees, alongside buildings, or on the north side of structures.
-
Soil: While Pachysandra is adaptable to various soil types, it flourishes in a slightly acidic (pH 5.5 – 6.5), moist, and well-draining soil. If your soil is heavy clay, amend it with organic matter like compost or leaf mold to improve drainage and texture. For very sandy soils, adding organic matter also helps with moisture retention.
-
Spacing: Plant Pachysandra cuttings 6-12 inches apart. This spacing allows for adequate room as the plants spread and fill in the area. Closer spacing will result in quicker coverage, while wider spacing means a longer wait for a full groundcover effect.
-
Planting Time: The best times to plant Pachysandra are in early spring or early fall. This gives the plants time to establish their root systems before the extreme temperatures of summer or winter set in.
-
Planting Process:
- Dig holes approximately 4-5 inches deep and 6 inches in diameter.
- Gently place a Pachysandra cutting in each hole, ensuring the roots are in contact with the soil.
- Backfill the holes with soil, gently tamping it down around the base of the plant.
- Water the newly planted Pachysandra thoroughly and deeply to settle the soil and encourage root growth.
Caring for Your Pachysandra Ground Cover
- Watering: Water regularly until established. Once established, Pachysandra is somewhat drought-tolerant, but deep watering during dry spells is beneficial.
- Fertilizing: Apply a balanced, slow-release fertilizer once a year in spring.
- Pruning: Prune in early spring before new growth begins to control size and shape. You can also lightly shear the tips to encourage bushier growth.
- Mulching: A layer of mulch helps retain moisture, suppress weeds, and add nutrients as it decomposes.
Common Pachysandra Problems & Solutions
- Volutella Blight: This fungal disease causes brown spots and stem dieback. Treat with a fungicide and remove infected plant parts.
- Scale Insects: These small pests can be controlled with insecticidal soap.
- Winter Burn: In colder climates, Pachysandra foliage may turn brown in winter. This usually recovers in spring.
Using Pachysandra in Your Landscape
- Under Trees and Shrubs: Pachysandra excels in the shade of larger plants.
- Erosion Control: Its dense root system helps stabilize slopes.
- Borders and Edging: Creates a tidy, defined edge along paths and flower beds.
- Foundation Plantings: Softens the look of building foundations.
Additional Tips
- Propagation: Pachysandra is easily propagated by division or cuttings.
- Patience: Pachysandra may take a few seasons to establish and spread fully.
