In this guide, we’ll explore how to plant and care for the Wintergreen Boxwood to ensure it stays healthy and beautiful for years to come.
What is a Wintergreen Boxwood?
Wintergreen Boxwood (Buxus sinica var. insularis ‘Wintergreen’) is a compact, slow-growing evergreen shrub that can reach heights of 2-4 feet and a similar spread. It features small, oval-shaped leaves that remain bright green throughout the year, even in cold winters. This boxwood is particularly prized for its cold-hardiness, making it an excellent choice for regions with harsh winters.
Why Choose Wintergreen Boxwood?
• Year-Round Color: Retains its vibrant green foliage through all seasons, even in cold climates.
• Cold Hardy: One of the most winter-hardy boxwoods, suitable for colder regions.
• Low Maintenance: Requires minimal pruning and care, perfect for busy gardeners.
How to Care for Wintergreen Boxwood
The Wintergreen Boxwood is relatively easy to grow, but following a few basic care guidelines will ensure it remains healthy and vibrant.
1. Sunlight Requirements
This shrub thrives in partial to full sun, although it prefers some afternoon shade in hotter climates to prevent leaf scorch. Choose a planting location with 4-6 hours of sunlight for optimal growth.
2. Watering Needs
Water deeply and regularly during the first growing season to establish a strong root system. Once established, the Wintergreen Boxwood is moderately drought-tolerant but performs best with consistent moisture, especially during hot, dry periods.
3. Ideal Soil and Climate
The Wintergreen Boxwood prefers well-draining soil that is slightly acidic to neutral. It is hardy in USDA zones 4-9, making it suitable for a wide range of climates, including colder regions where other boxwoods may struggle.
4. Fertilizing
Fertilize in early spring with a balanced, slow-release fertilizer to encourage healthy growth. Be careful not to over-fertilize, as this can cause the foliage to yellow.
Common Issues and Solutions
• Leaf Browning: Often caused by winter burn or drought stress. Mulch around the base of the plant to retain moisture and protect roots from extreme temperatures.
• Pests: Wintergreen Boxwood can be susceptible to boxwood leafminers and spider mites. Treat infestations with insecticidal soap or neem oil as needed.
Pruning and Maintenance
Prune in late winter or early spring to shape the shrub and remove any dead or damaged branches. Regular light pruning helps maintain the plant’s natural shape, but avoid heavy pruning, as it can lead to sparse growth.

The Wintergreen Boxwood is versatile and can be used in a variety of ways in the landscape, including:
• Hedges and Borders: Its dense growth makes it ideal for low hedges or garden borders.
• Foundation Planting: Perfect for framing entryways or softening the edges of a home’s foundation.
• Topiary: This shrub’s compact growth makes it an excellent candidate for shaping into topiaries or formal garden designs.
