Boxwood Care & Maintenance
Planting:
- Choose a site with full sun to partial shade.
- Use well-drained soil; amend with organic matter if needed.
- Space plants 2–3 feet apart for seamless hedges.
Care:
- Water regularly during the first growing season to establish roots. Ensure that your shrubs receive adequate water in late fall. Moisture in their leaves will protect your evergreens against drying winter winds and windburn.
- Fertilize in early spring with a balanced fertilizer.
- Prune or shear lightly in late winter or early spring to shape and remove dead or damaged growth. These are naturally dwarfed shrubs that will remain small. They can be easily sheared into tight, upright ovals.
- Mulch around the base to retain moisture and regulate soil temperature.
