What are the best evergreen trees for a privacy screen in NB?

Eastern white cedar (Thuja occidentalis) is the top choice for evergreen privacy screens in New Brunswick, offering year-round dense foliage, excellent cold hardiness to zone 3, and a naturally columnar growth habit that requires minimal pruning. Cedar screens are ubiquitous across the province for good reason — they grow well in NB's acidic soils, tolerate moderate shade, and can be planted as close as 3-4 feet apart to create a solid visual barrier within 4-5 years.

For a standard residential privacy screen in the Fredericton or Moncton area, plant 6 to 8-foot tall cedar transplants spaced 3 to 4 feet apart on centre. At this spacing, the trees will grow together into a continuous hedge within 3-5 growing seasons. Expect to pay $80-200 per tree at this size from NB nurseries, or $40-80 for smaller 3-4 foot specimens that will take longer to fill in. Cedar grows approximately 6-12 inches per year in New Brunswick, eventually reaching 20-40 feet if left unpruned, though most homeowners maintain their screens at 8-15 feet with annual trimming in late June.

White spruce is an excellent alternative for exposed or windy sites where cedar might struggle. Spruce grows faster than cedar — up to 18 inches annually — and its stiffer branches handle NB's heavy snow and ice loads better. However, spruce trees are wider at the base, requiring 8-10 foot spacing, and they do not respond as well to tight hedge-style pruning. They work best as a naturalistic screen rather than a formal hedge. For coastal properties in Saint John or Shediac, white spruce also provides superior salt tolerance compared to cedar.

Colorado blue spruce offers a striking blue-silver colour and grows reliably in NB zones 4-5, though it is susceptible to cytospora canker and needle cast diseases in humid Maritime conditions. Use it as an accent within a mixed screen rather than the primary species. Eastern hemlock creates a beautiful, soft-textured privacy screen and tolerates shade better than any other NB evergreen, making it ideal for north-facing property lines. However, hemlock grows slowly (6-10 inches per year) and is sensitive to winter wind exposure, so it performs best in sheltered locations in southern NB.

When planning your privacy screen, consider mature width as carefully as height. Cedar needs 3-4 feet of clearance from property lines and fences to maintain healthy growth on all sides. In NB municipalities, check local bylaws regarding hedge heights and setbacks before planting — Fredericton, Moncton, and Saint John all have specific regulations. A professionally installed cedar privacy screen of 20-30 trees typically costs $2,500 to $6,000 in New Brunswick, including trees, soil amendment, mulch, and planting labour.
