Gardening and Landscaping
Choose evergreen trees by mature width, site conditions, and upkeep.
A narrow side yard can feel private without losing its walkway. Choose trees for their mature width as well as height, since a slim nursery plant can broaden over time.
Columnar evergreens have naturally narrow, upright crowns, useful along property lines, driveways, and side yards. The term describes growth habit, not a guarantee of a pencil-thin mature tree.
‘Taylor’ juniper and Italian cypress are among the slimmest choices for sunny, narrow strips. Junipers need sun and well-drained soil; Italian cypress suits mild regions and good drainage.
‘Emerald Green’ arborvitae is a common choice for a fuller, moderate-height screen. ‘Green Giant’ grows quickly, but needs much more room at maturity, so it may not suit a tight strip.
‘Taylor’ juniper reaches an approximate mature height of 15–20 feet and width of 3–5 feet. Treat published size ranges as planning estimates and verify the plant tag before buying.
Compare hardiness, sunlight, drainage, and summer moisture before choosing a cultivar. Wet, compacted soil can cause decline, while many screening conifers need good light to grow dense foliage.
For a connected screen, start by spacing trees about 60–80% of their expected mature width apart. Adjust for branching habit and desired coverage, rather than planting tightly for instant privacy.
Set the tree at its nursery depth with the root flare visible at soil level. Make a broad hole no deeper than the root ball, water thoroughly, and keep the root zone evenly moist as it establishes.
Planting too closely can make crowns compete for light, water, and root space. Pruning has limits: it cannot reliably shrink a mature crown or restore foliage on bare old wood in many conifers.
For a very narrow sunny strip, consider ‘Taylor’ juniper or Italian cypress where climate permits; choose ‘Emerald Green’ for a moderate-height screen. Let mature width guide your final spacing.
