Expert tips
The key tip
Pachysandra terminalis slowly colonizes shaded areas as a dense, low carpet: it needs no maintenance and thrives in poor soil as long as it stays moist. A mow every 3-4 years in February keeps it dense.
The common mistake
Waiting too long for it to spread: it grows very slowly in the first two years, so be patient.
The pro's trick
Plant at tighter spacing from the start (every 25-30 cm) if you want a uniform carpet in two years instead of four.
Care
Light Exposure
Pachysandra prefers partial shade to full shade, ideal under trees or along north-facing walls. It thrives well in shaded areas where few plants flourish. Avoid prolonged sunny exposures that can scorch the foliage.
Watering
Water regularly during the first year to establish the plant. Once established, it's moderately demanding and tolerates relative dry periods. Keep the soil moist but not waterlogged, especially in summer.
Soil Preparation
Prepare soil enriched with compost or peat before planting. Pachysandra appreciates slightly acidic to neutral soils. Good drainage is essential to prevent root rot.
Pruning and Maintenance
Low maintenance, it requires virtually no pruning. Light cleanup in spring to remove dead leaves is sufficient. You can trim it back lightly every 3 to 4 years to stimulate density.
Fertilizing
Apply balanced fertilizer in spring or add compost annually. Pachysandra isn't very demanding and often thrives on the fertility of soil enriched at planting time.
Diseases and Pests
Generally very resistant, it may occasionally suffer from root rot if soil is too wet. Watch for spider mites in very dry air. Good air circulation and adequate drainage prevent most problems.
Did you know?
Pachysandra terminalis is historically used in Japan as a traditional ground cover in zen gardens. In the West, it became a highly prized plant among 20th-century landscapers to revitalize difficult areas under deciduous trees, where it creates a dense and timeless plant carpet.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
