Eastern Redcedar

Juniperus virginiana

Eastern Redcedar is a tall native evergreen that brings year-round vertical structure to sunny, open parts of the landscape. Its 40-foot height makes it better suited to property edges, broad beds, and large-scale screening than to small foundation plantings. The narrow 15-foot mature width lets it form a substantial green wall without consuming the footprint of a broad-canopied shade tree. It is hardy in USDA Zones 2 through 9 and handles low-water settings.

Eastern Redcedar spacing and mature footprint

Space Eastern Redcedar 15 ft apart, measured center to center (4.6 m).

The mature spread is about 15 ft (4.6 m), so neighboring plants just meet at maturity without crowding.

Treat 15 ft as a planning baseline — cultivar and local growing conditions shift the final footprint.

Placement and use

Use Eastern Redcedar along an outer boundary, driveway edge, or exposed side of a property where a tall evergreen screen or windbreak can develop without blocking needed views. Its dense, upright to pyramidal form works especially well in repeated rows or loose groups rather than tucked into a mixed border. Keep the planting line far enough from buildings, overhead utilities, and narrow paths that the mature canopy will not crowd circulation or cast unwanted shade on sun-dependent beds.[1][2][3]

Spacing and mature footprint

Set plants 15 feet apart, center to center, for a continuous long-term planting rhythm. That spacing matches the expected mature width, so neighboring trees can meet visually while retaining room for individual crowns. Reserve a planting strip at least 15 feet deep from the back edge of a bed toward paths, fences, or structures, and allow additional setback where access is needed for mowing, pruning, or fence maintenance.

Sun, water, and soil

Place this tree in full sun, where it can hold a dense form and make the most of its drought tolerance. It accepts a broad range of well-drained soils, including dry, rocky, shallow, and poorer ground, making it useful where less adaptable evergreen screening would be difficult. Avoid sites that remain continuously wet, and do not rely on it to fill a shaded side yard once established.[1][2]

Seasonal notes

The evergreen canopy keeps a screen or windbreak present through winter, when its spatial role is often most noticeable. Female trees may carry blue, berry-like cones that ripen in fall, while foliage can take on bronze to yellow-brown tones in winter. Plan the tree primarily for persistent structure rather than a brief seasonal display, and give its full height clear visual room in every season.[1]

Planning caveats

Avoid placing Eastern Redcedar immediately beside apple plantings. It can share a rust fungus with apples, so separating these plants is a sensible layout decision when apples are part of the same garden plan. Also account for the tree’s substantial eventual height before using it near solar exposure zones, vegetable beds, or areas where winter light is important.[1]
