How to Grow Pachysandra
Pachysandra terminalis
Pachysandra is the ultimate low-maintenance evergreen ground cover for shade. It spreads steadily by underground runners to form a dense, weed-suppressing carpet of glossy dark green leaves. Plant 30cm apart in humus-rich, moist but well-drained soil in partial to full shade. It is slow to establish in the first year or two but once settled requires almost no attention. The small white flower spikes in spring are insignificant — this plant is all about the foliage.
Yearly Lifecycle
Care Essentials
Rarely needed. A light mulch of leaf mould in spring helps maintain the humus-rich soil it prefers. Avoid heavy feeding which encourages leggy growth.
Watch For
- Volutella blight (brown patches in foliage)
- Scale insects on stems
- Leaf scorch in too much sun
Companions
Hostas, Ferns, Hellebores, Epimedium
Care Requirements
Light
Partial to full shade
Thrives in deep shade under trees where little else grows. Scorches in full sun. North-facing banks and woodland floors are ideal.
Watering
Moderate, consistent moisture
Prefers moist but well-drained soil. Water during establishment and prolonged dry spells. Once settled, largely self-sufficient in shaded positions.
Fertilizing
Light leaf mould mulch in spring
A thin layer of leaf mould or compost in spring mimics the woodland floor conditions it prefers. Heavy feeding encourages leggy growth.
Pruning
Shear leggy patches in early spring
If sections become bare-stemmed after several years, shear hard in early spring. Regenerates quickly from the base. Otherwise minimal pruning needed.
Growing Tips
Patience in the first years
Pachysandra is notoriously slow to establish. It may look sparse for 1-2 years before the underground runners knit together into a dense carpet. Do not give up on it.
Shade is essential
This plant scorches in full sun. It performs best in partial to full shade under trees or on north-facing banks where other ground covers struggle.
Shear leggy patches
If sections become bare-stemmed or patchy after several years, shear the entire area back hard in early spring. It regenerates quickly from the base.
