Shaping Evergreen Hedges: Boxwood, Yew, and Arborvitae Tips | NH Seacoast
Why Evergreen Hedges Need Proper Care on the Seacoast
Evergreen hedges are the framework that gives a garden its shape, marking boundaries, providing privacy, and staying green even through the long New England winter. But without proper pruning, these reliable plants can develop bare spots, grow unevenly, or lose the dense structure that makes them so valuable. On the Seacoast, where strong winds, salty air, and sandy soils already place stress on evergreens, learning how to prune and shape them correctly is especially important for keeping them healthy and attractive year-round.
Boxwood Basics
Boxwood is a classic choice for low hedges and formal garden designs, offering a neat, structured look that frames flower beds and walkways beautifully. To keep boxwood healthy, it’s important to prune with a light and steady hand. These shrubs respond well to regular, gentle trimming, but they do not tolerate being cut back into old wood, which can leave permanent gaps. The best time to prune is after the first flush of growth in late spring, with small touch-ups during summer if needed. Using sharp hand pruners ensures clean cuts, improves air circulation within the plant, and helps prevent disease. A little attention each year keeps boxwood dense, green, and shapely without causing stress.
Yew’s Flexibility
Yews are a versatile option for Seacoast landscapes and are generally more forgiving than boxwood when it comes to pruning. Unlike many evergreens, they can regenerate even if cut back hard into old wood, making them ideal for taller hedges or situations where a hedge needs a complete reset. For major cutbacks, the best time is early spring before new growth begins, while light shaping can be done through the summer to keep them tidy. Known for their tough, dark green foliage and reliability, yews remain a dependable choice for homeowners who want both structure and resilience in their hedges.
Arborvitae Care
Arborvitae is one of the most popular choices for privacy screens, thanks to its fast growth and ability to form a solid wall of evergreen foliage. However, unlike yew, arborvitae does not recover once branches are cut back into bare wood—any stripped sections usually remain that way permanently. To keep these hedges looking full and healthy, it’s important to prune lightly each year, taking off only a little at a time. The best season for shaping is late spring to early summer, after new growth has appeared. With careful yearly attention, arborvitae will maintain its dense, vibrant structure and provide lasting privacy for your landscape.
Seacoast Challenges
Living near the coast brings unique challenges for evergreen hedges. Strong winds, salty air, and sandy soils can place added stress on plants that are already working hard to stay green year-round. Salt spray may cause foliage to brown, while sandy soils tend to dry out quickly, leaving roots thirsty and stressed. To counter these conditions, gardeners should focus on mulching to retain moisture, deep watering to encourage strong roots, and balanced fertilizing to support steady growth. Pruning at the right time of year also gives evergreens the best chance to recover from stress, keeping them dense and full even in the face of tough Seacoast conditions.
Recap: Key Points for Evergreen Hedges
Boxwood thrives with light, regular trims and should never be cut back into old wood.
Yew is highly adaptable, able to regenerate even after heavy pruning, making it one of the most forgiving choices.
Arborvitae need gentle yearly shaping and will not recover if branches are cut into bare wood.
Seacoast conditions—including wind, salt, and sandy soils—mean hedges require careful timing and extra attention to stay healthy and full.
